Why is the Sky Purple?
Source Institutions
This simple hands-on activity demonstrates why the sky appears blue on a sunny day and red during sunrise and sunset.
Odd or Even
Source Institutions
In this math activity, learners play a game and try to collect the most cards by guessing if the next number to appear will be odd or even.

Model Well
Source Institutions
In this quick activity about pollutants and groundwater (page 2 of PDF under Water Clean-up Activity), learners build a model well with a toilet paper tube.

An Object in Motion
Source Institutions
In this physics activity (page nine of the pdf), learners use balloons to explore how a rocket works. It is suggested they also work to see how they can alter the velocity of the rocket.

Flubber: Make a polymer!
Source Institutions
This activity (on page 2 of the PDF) features a recipe to create the stretchy polymer Flubber from Borax detergent, white glue, and water.

Sand Paper Rankings
Source Institutions
In this activity (2nd activity on the page), learners explore the sensitivity of their sense of touch.

Snake
Source Institutions
In this physics activity (page 4 of the PDF), learners will construct their own spiral "snake" and use it to explore the relationship between heat and kinetic energy.
Coat Hanger Chimes
Source Institutions
In this physics activity (page 4 of the PDF), learners will--using nothing more than a coat hanger and some string--explore and understand sound energy and how it moves.

Outbreak!: Investigating Epidemics
Source Institutions
A group of learners simulates the spread of disease by trading slips of paper, one set of which has been treated with a baking soda solution.

Making Circuits
Source Institutions
In this activity, learners explore electricity and conductivity to find that many things conduct electricity including copper, pencil lead, fruit, play-doh, and even people!

Keeps on Pumpin': Your Heart
Source Institutions
In this activity, learners explore the great pump in their chests--the human heart!

Plaster Casts
Source Institutions
In this activity, learners combine two substances (plaster of Paris and water) to make a cast of an object's imprint in clay.
PomPom Toss
Source Institutions
In this activity, learners play a game that helps young mathematicians recognize how the numbers 0 through 5 are related. Learners toss five pompoms into circle made out of string on the floor.

Convection
Source Institutions
In this activity, learners model atmospheric convection currents using food coloring, water, and clear cups. Activity includes step-by-step instructions, STEM connections, and more.

Fraction Penguin
Source Institutions
In this craft activity, learners will recognize, name, and compare the fractions 1/2, 1/4, and 1/8 by constructing a penguin out of portions of paper circles.

Sticky Situation
Source Institutions
In this activity, learners separate the protein from milk and and use it to make their own glue.

Thumb Piano
Source Institutions
In this activity, learners explore sound by constructing a simple piano out of wood and craft sticks.
