The next South Shore Science Festival is Saturday, April 22, 2017, from 10 to 3.
Same location: 180 Old Colony Avenue, Quincy, Mass. (10 minute walk from the Wollaston T on the Red Line) That's the Quincy Center for Innovation. This is part of the Cambridge Science Festival, which is now statewide.

STEM (as it's more often referred to) and STEAM are guide words in education now:
Science -- Technology -- Engineering -- Arts -- Mathematics
Rather than teaching the traditional subjects of science, art and math separately, combining them makes them much more meaningful. Including technology and engineering makes them much more practical.
Many of the same presenters from the last two years will be there again, with a number of new presenters, too. (Some of them were students who shared their science fair exhibits with us.) As plans become more firmed up, I'll list them in this post. See www.southshorescience.org for pictures from the past two festivals.
If you love playing sports and games but think you don't like science, think again--SPORT SCIENCE. Welcome to Gateway to Science: Sports and Games!

ARIZONA...WHERE THEY'VE GOT IT TOGETHER TO HELP KIDS LEARN THE SCIENCE OF SPORT!
This is a program I found recently, and I think it's a wonderful model. This is my summary of highlights of the website. Science of Sport, an Arizona nonprofit, is only a few years old. They work with the College of Engineering at the University of Arizona, state and local departments of education, and various professional sports teams.
SCIENCE
OF SPORT
602-525-3197
Tucson,
Arizona
To
date: 894 teachers trained / 44,700 students reached
BACKGROUND:
Science of Sport was founded by Ricardo Valerdi, Ph.D.
Initially the goal was to teach math through baseball, but it
has expanded to baseball, soccer, basketball and football
science with teacher workshops / lesson plans / student camps /
webinars. SOS has gone beyond Arizona to the West Coast and
East Coast and Australia.
NOTE: I
found information on the baseball and soccer programs but no news
turned up when I clicked on basketball and football.
VIDEO: Introductory
6.5 minute video with Ricardo Valerdi and:
Darren
Heaton VP, business development, SOS / former manager, Education
Initiatives, Arizona Diamondbacks
Kevin
Brungardt Middle school social studies teacher. Over 25 lesson plans
include trajectory, nutrition, baseball analytics.
Ballard

The Bite have a one-day program for middle school students with
eight STEM lessons on Australian baseball.
PROFESSIONAL
DEVELOPMENT, BASEBALL
SAN
DIEGO
San
Diego Padres, Science of Sport, and San Diego Gas & Electric ran
a professional development workshop for 40 teachers in the San Diego
area. It was a one-day workshop from 9 to 2, and it introduced 12
lesson plans to math, science, and PE teachers for grades 5 to 8. It
covered: geometry, trajectory of the ball flight, aerodynamics,
elasticity, biomechanics, in addition to physiology, nutrition,
reaction time, baseball statistics, scoring, strike zone, rules of
baseball, and ballpark design.
SOCCER
PROFESSIONAL
DEVELOPMENT, SOCCER
LOS
ANGELES
The
LA Galaxy Foundation funded the initial training of 25 teachers from
the Newport Mesa School District, later began promoting this
throughout southern California.
A
video is narrated by Ricardo Valerdi, with comments from teachers
Katie Holt, Kurt Suhr, and Tarym Flamson. I watched “The Science
of Penalty Shootout” video on how to score 100% penalty kicks.
Besides
teaching the kids pointers on how to play soccer -– players and
positions / dribbling and passing / penalty kicks and goalies –- as
well as character development, the science includes aerodynamics /
trajectory of ball flight / momentum, plus physiology and nutrition
and training.
BASEBALL
AND SOCCER
Anaheim,
CA – December 23, 2015
The
Anaheim City School District has received a $1,050,000 STEM
education grant from the California Department of Education
that will be funded over a three-year period.
Additionally, the Orange County Department of Education, Angels
Baseball and the LA Galaxy will provide an additional
$500,000 in in-kind support for the program.
The
grant and in-kind support will allow 35 teachers from the
Anaheim City School District to become Master Teachers for
the Angels Science of Baseball and the LA Galaxy Science of
Soccer programs.
The
programs teach kids how STEM subjects relate to sports through
real- world examples.

THE SCIENCE OF SPORT -- A COMPREHENSIVE PROGRAM! (introduction)
This is a link to a terrific program I just found:
http://www.sciencesport.org/portfolio-items/san-diego-padres-science-of-baseball-teacher-workshop/
They don't just do a teacher workshop on the science of baseball. They have student camps and a webinar program. And they do basketball, soccer and football, too! They have helped the Arizona Diamondbacks and LA Galaxy develop programs which educate kids about science in sports, which I've already mentioned in this blog, plus the Houston Astros, Colorado Rockies, and Los Angeles Angels of Anaheim, to name a few.
This is from their website:
The Science of Sport is a non-for-profit foundation dedicated to developing curriculum and programming that promotes Science, Technology, Engineering and Mathematics (STEM). Our curricula are designed as in-school exercises that can be delivered by teachers or as after school programs that can be delivered by parents, coaches, and volunteers. The focus on middle school students is motivated by the fact that this age group can still be influenced to make academic choices that will help them transition from primary to secondary education.

LA Galaxy...Science of Soccer
The LA Galaxy have had a soccer science program since 2014:
I wasn't able to put the video here, but here is the link: https://youtu.be/zVFQyfoL15w
I wasn't able to put the video here, but here is the link: https://youtu.be/zVFQyfoL15w
The LA Galaxy Science of Soccer presented by Konica Minolta is an exciting series of community programs and initiatives that teach STEM (Science, Technology, Engineering and Math) in a fun and dynamic way through soccer. The curriculum includes brief lessons that use soccer demonstrations as hands-on inquiry based learning to spark interest in real-life applications of STEM knowledge. The goal is to translate the love of soccer into an appreciation, understanding and passion of the science and mathematics underlying the sport.
The LA Galaxy have partnered with Science of Sport, a non-profit organization, to develop the curriculum and align it with all current and future California standards like Common Core Standards and Next Generation Science Standards. The curriculum can be custom tailored to participating teachers and students in grades 1-12.
The LA Galaxy Science of Soccer schedules teacher camps, student camps and other engagements each semester during the school year and in the summer to teach the programs. Teachers are expected to take the curriculum back to their classrooms and are given all of the tools to implement the lesson plan at their school with their students. All teachers and students participating in the program receive a ticket to attend a LA Galaxy home match during the regular MLS season.
Examples of topics covered:
- The basic rules of the game, different player formations, dimensions of a soccer field
- How to dribble and pass the ball
- How to measure surface areas of various parts of feet used to kick and dribble a ball
- Test speed and accuracy in the context of Newton’s Laws of Motion
- Angles and possibilities associated with a penalty kick scenario
- Reaction time: speed, accuracy and control
- Aerodynamics – effects on a soccer ball moving through air: spin/curl, wind resistance, force, angle of trajectory
- Recording data
- Nutrition – relationship between healthy diet and athletic performance
- Muscle fatigue
- Heart rate
The LA Galaxy are proud to partner with the Angels and the Anaheim City School District who have received a $1 million, three-year grant from the California Department of Education to develop STEM.

San Francisco 49ers STEAM Education Program
I copied and pasted this article from www.49ers.com. You know, the SF 49ers can be a role model for professional sports teams to promote the learning of science through sports. Hands-on plus online (the online part via Khan Academy) makes this unique. Not to forget the Arizona Diamondbacks who have hands-on activities for kids before the games, too (see post further below in this blog).
What can YOU do to urge other teams to emulate "the first professional sports organization to embrace the STEAM learning concepts for youth"?
49ers STEAM Education Program Launches Online Learning Content Available on Khan Academy
Posted Sep 14, 2016
The San Francisco 49ers today unveiled online supplemental learning resources for students and teachers available free on Khan Academy to support the 49ers STEAM Education Program. The free online content extends the 49ers STEAM Education Program’s impact beyond the walls of the Levi’s® Stadium field trip program.
Now entering its third year in operation with more than 90,000 students reached to date, the 49ers STEAM Education Program provides learning platforms for K-8 students through its education program that teaches content-rich lessons using the STEAM principles of science, technology, engineering, art, and mathematics.
“Khan Academy’s online learning platform is exceptional and we’re thrilled to work with them to take the next step in growing our STEAM Education Program,” said 49ers Director of STEAM Education and the 49ers Museum Jesse Lovejoy. “Khan Academy will enable our program to go beyond the walls of Levi’s Stadium and provide students who we couldn’t previously reach with unique, exciting content that combines STEAM with football.”
The 49ers are the first pro sports organization to partner with Khan Academy. The organizations started working together in 2015 for the launch of LearnStorm, a math competition that rewards grit and hard work in addition to math mastery.
“The San Francisco 49ers have supported education for many years,” said Khan Academy founder and CEO Sal Khan. “We’re excited to make math and science lessons that are related to football widely available free for anyone, anywhere.”
As the first professional sports organization to embrace the STEAM learning concepts for youth and provide free onsite programming, the 49ers STEAM Education Program aims to tangibly show students how STEAM is applied at a professional football team.

A FOOTBALL REALLY RISING ON ITS TIPPITY-TOES?!
Welcome back, Tom Brady. You're the man!
In the New England Patriots v. Cleveland Browns football game today I saw Rob Gronkowski spin the football so that it stood upright. Do you know what that's called? It's spinning around its axis of rotation.
We all learn in school that the earth spins, or rotates, on its imaginary axis. It's the same with the football. Everything that turns has an axis of rotation.
Well, as you know, because of the shape of a football, it normally lies the long way.
It lies in a horizontal plane,
like this: __
When Mr. Gronkowski made the ball spin, we saw the ball move from that horizontal plane,
up through a diagonal plane,
like this: /
rising to an upright position in the vertical plane,
like this: !

LEAFLET: PHYSICS OF SWIMMING
DID
YOU KNOW THAT
YOU
CAN LEARN PHYSICS
FROM
SWIMMING ?
Learn
about the science in:
● Moving
Through Water vs. Moving Outside Water
● Diving
vs. Cannonball
It
looks at the following questions:
What
is the connection
between
buoyancy and gravity?
Why
is water more viscous than air --- and just WHAT does
viscous mean?!
What
simple machine in my body helps me swim?
GATEWAY
TO SCIENCE:
Sports
and Games
-----------------------------------------------
INSIDE p. 2 (left)
WHAT
KIND OF FORCES ARE INVOLVED IN ….?
walking
– bicycling – swimming
Walking Lifting my legs and swinging my arms, I work against GRAVITY (and
AIR RESISTANCE if I walk into the wind).
Bicycling Because I'm moving faster than walking, I'm working against
more AIR
RESISTANCE plus GRAVITY.
Swimming My BUOYANCY tends to cancel out the effect of GRAVITY.
(See the center column.
)
One
more thing!
WATER
RESISTANCE slows you down.
This is because water is more
VISCOUS and more DENSE than air.
Well,
what does viscous mean?
A
viscous liquid is resistant to flow. Think of molasses, honey,
and ketchup!
What
does dense mean here? The same amount
of water (a liquid) weighs more than the same amount of air (a
gas). Think of a balloon full of water vs.
a balloon full of air!
------------------------------------------------------------------------------
INSIDE p. 3, center
WHAT
KIND OF THINGS CAN I LOOK FOR?
Let's talk about
buoyancy!
Definition:
Buoyancy: Tendency
to float or rise when submerged in fluid
Buoyancy
is the balance between:
pressure
of water, pushing UP
and
force
of gravity, pulling DOWN
When you are
stretched out flat,
there is more surface for the water to push UP
on.
Therefore (∴)
:
Cannonball
© vs. Diving \
With
a small, concentrated surface area, you will sink!
------------------------------------------------------------------------------------------------
INSIDE p. 4 right
Newton's
3 Laws of Motion
1st An
object not moving tends to stay that way unless it comes in contact
with an outside force. An object that is in motion also has a tendency to stay that way, unless it comes in contact with an outside force. This tendency is called INERTIA. The tendency for a moving object (you) to stay in motion, when swimming, does not hold up well due to water resistance. Why? Water resistance is the “outside force” acting on the object, you.
2nd Force
is mass combined with acceleration --- or F = m∙a
Let's think about simple machines. What parts of your body work as a simple
machine to accelerate yourself and give more FORCE
and speed for less effort?
(Is this part:
an inclined plane? a screw? a lever? a rope and pulley? a wedge?
a wheel and axle?)
3rd Every
ACTION has an equal and opposite REACTION.
So when you push
backward – an action – on the side of the pool,
you go forward – an equal, opposite reaction.
-------------------------------------------------------------------------------------
OUTSIDE, left
NOTE
The
terms water resistance and air resistance used in
this leaflet are commonly referred to as “drag.”
Sports
and games are the gateway to science,
and
YOU hold the key!
Also,
did you know......?
Muscle
is more dense than fat
--- so fatter people are more buoyant.
_________________________________________________________
OUTSIDE, center (this is the back of the leaflet)
SWIMMING........
is
just one of endless ways to gain an understanding of physics and
geometry. I hope this leaflet introduces you to seeing
things you never saw before – or wondered about but just didn't
know where to start.
Physics
and geometry come into play in every activity and event going on
around us.
Knowing
how things work can add to your performance and to your fun. So give it a try. How?

POWER OF TEN lists, rev. 9.26.17
POWER
OF TEN
My POWER
OF TEN lists are groups of 10 science terms. In my study of physics and sports and games, etc., these words have stood out for me. They stand out because for the most part they are terms, or concepts, that we already understand in everyday life.
Many of them are self-explanatory. Others need a little explanation but can be easily understood. To some extent these words are arranged here so that you can see their relationship to each other. If you make up sets of 10 cards each, you will hold in your hand a solid start to gaining a working knowledge of physics and geometry.
Here is the POWER OF TEN.
I believe that with these you will begin to have the power!

RARE METALS USED IN iPHONES
THE
NEW NECESSITIES [for iPhones]
in
Boston College Magazine, Spring 2016, pages 44-46
David
S. Abraham, BC 1996
There
is “magic” in the glass of an iPhone, due to rare metals. Here
are some rare metals used in an iPhone:
Iridium Malleable,
the invisible link, a transparent conductor
between your finger and the telephone
Europium
& Terbium These rare metals provide the red and green hues.
Tantalum Regulates
the power in the phone.
Lithium Stores
power that makes the phone mobile.
Cerium Used
to buff the glass smooth to the molecular level.
Other
metals he discusses although he doesn't specify their function in an
iPhone:
Niobium Ductile
Cadmium Toxic
Thorium Radioactive
Cobalt Magnetic
Gallium May
melt in your hand.
Antimony Helps
resist fire.
Dysprosium
& Neodymium
Contained
in the rare earth permanent magnet. They help computer drives
to retain information. (They also help to propel hybrid
vehicles.)
Gallium
& Indium
These
rare metals are found in LED lights, along with rare earth elements.
Cf. Edison's bulb which had a simple carbon filament.
Tellurium Most
“rare metals” are called rare because they're mined in small
quantities compared with, for example, copper. But Tellurium is
geographically rare. It is used in metal alloys.
Some
“nuggets” I found in the article:
- Decades ago scientists dismissed these elements as impurities.
- In the 1980s Steve Jobs bought the home of mining magnate Daniel Jackling.
- Intel used 16 elements in computer chips in 1990. Almost 60 elements are being used in computer chips by 2016.
- Trade in rare metals takes place in backrooms rather than on open commodity exchanges, obscuring the size of the markets and the market price.
- The world is fast becoming as dependent on rare metals as it is on oil.

String-Can Telephones: Lesson Plan
LESSON
PLAN
STRING-CAN
TELEPHONES
LEAD
IN with SCIENCE OF SOUND
- Have you noticed that when you talk and your voice fades, you take a breath? Why?
- The sound of your voice starts with air passing over your vocal cord, AKA voice box. Your voice box will move (or vibrate) as you speak. Place your fingers over your vocal cords; your fingers might tickle as you speak. (Demonstrate; they try it.)
- Think about what you do to direct your voice:To whisper, cup your hands around your mouth and speak softly into someone's ear.To shout, put your hands to each side of your mouth and shout to everyone.
- Today we'll learn how to make our voice travel over a distance -– without shouting!
STRING-CAN
TELEPHONES
- This is what “telephone” means: (tele – = distant - phone = sound)
- This is what happens when talking and listening face-to-face:As we've already seen, our vocal cords move -– they vibrate. And the sound wave travels in the air, which is called a medium. Your friend's eardrums vibrate – and he hears you!
- This is what you can do when talking and listening over a distance: To do this without shouting -– make a string-can telephone! (show one).a. Speak into the can. The string and can vibrate. The vibration travels in sound waves.b. The sound wave's vibration travels along the string to the 2nd can, and then the other person hears. (Have 2 kids demonstrate.) c. c. You need to keep the string taut, as the sound travels best this way. Do not let the string sag or bend, either.
- Show them how to make one. (Pass out supplies.) Every 2 children make one set.
- Try them out.WRAP-UP
- Review what happens.air passes over vocal cord ----- vocal cord vibrates ----- sound wave travels through air to string at bottom of can ---- can and string vibrate ---- sound wave's vibration travels along the string to the 2nd can ---- be sure to keep that string taut ---- the other person's eardrum vibrates and he hears you
- Investigate further! use different kinds of cups and cans –--- use different kinds of strings ---- use different lengths of strings ---- chart the results * (see p. 2). What works best?
- Pass out the leaflet; ask them to take it home.
Page 2
EVALUATION
Demonstrate
it and explain to someone else how it works!
Notes
on Vocabulary:
Underlined
words: Put up signs you make or write them on the board.
Vocabulary: air
– vocal cord / voice box – telephone – vibrate – medium –
taut
Introduce
whatever vocabulary seems appropriate for the group. Both “vocal
cord / cords” and “voice box” are introduced and are used
interchangeably. The medical term is: l a r y n x.
Tips:
Cans
are referred to in this lesson plan, but cups can be used instead.
The
leaflet “String-Can Telephones and How They Work” can be used to
show this visually.
Notes
on the String-Can Telephones:
When you have
some assistance in making the telephones, this lesson can be done in
about 45 minutes. Making the holes in the cans/cups ahead of time
will help to speed this up.
It's good if
you have two sets of phones for two children to share (one for the
ear, one for the mouth, so they don't need to keep switching one
phone from ear to mouth). However, if time is limited, one set will
do.
Plastic cups
are easier to make holes in, so you might want to start with them.
Later on, use different kinds of cans and cups and compare them.
You can
introduce a variable in the type of string and/or can with the groups
within the class. Each group would be assigned one kind of string /
can:
Each group
could use a fishing line / regular string / or dental floss
plus tin can /
styrofoam cup / or plastic cup.
The different
groups can swap and compare results using different kinds of string
and cup.

Leaflet: Basketball Backspin
DID YOU KNOW THAT
YOU
CAN LEARN PHYSICS
WHILE
PLAYING BASKETBALL?
This
is about the science involved in
IMPARTING
BACKSPIN!
---------
It
looks at the following question:
“I
don't want the basketball to bounce off the rim.
How
do I get the ball to stay there and drop into the basket?”
-------
GATEWAY
TO SCIENCE:
SPORTS
AND GAMES
INSIDE LEFT
Listen
to what a famous Boston Celtics coach said about this:
Fingertips
help to impart backspin, which makes the shot softer.
A ball that
strikes the rim and then stops has good backspin.
Red
Auerbach
_____________
-- A
shot from the fingertips is launched with backspin! --
What
happens without backspin?
When
you use the flat of your hand to throw the ball and the ball hits
the rim,
there will be some friction.
This
collision robs the ball of some of its energy. It will slow it down.
However,
the ball still has enough energy to keep it moving –
and it can
bounce right off the rim of the basket!
INSIDE CENTER
WHAT'S
THE SCIENCE BEHIND BACKSPIN?
▪ In addition to
traveling through the air, the ball is spinning,
or rotating on its axis.
or rotating on its axis.
▪ With spin, the bottom of the ball moves faster.
▪ When the bottom of the ball hits the rim fast, this collision will cause
enough friction so that the ball loses more energy.
▪ This slows the ball down, keeps it where you want it –
so that gravity can finish the job!

WHAT
WORDS WILL HELP ME TO UNDERSTAND THE SCIENCE SO THAT I CAN PLAY

AXIS OF
ROTATION...Just as Earth spins around on its axis of rotation,
a
basketball with backspin also spins on its axis of rotation.
COLLISION...Two
