Breaking Beams
Learners investigate stress and strain by designing, building, and testing beams made from polymer clay.
Exploring Bouncing Balls
Source Institutions
Learners explore the physical properties of a variety of balls and how they bounce.
M&M's in Different Sugar Solutions
Source Institutions
In this activity, learners investigate whether having sugar already dissolved in water affects the speed of dissolving and the movement of sugar and color through the water.
Scented Dough
Source Institutions
In this activity, learners follow a recipe to create play dough scented with fruit-flavored drink mix.
Charge and Carry
Source Institutions
In this activity about electricity, learners produce a spark that they can feel, see, and hear. Learners rub a Styrofoam plate with wool to give it an electric charge.
Density Rainbow
Source Institutions
In this activity, learners mix several sugar solutions to investigate the property of density. Each sugar solution has a different density and color of the rainbow.
Building with Wonderful Junk
Source Institutions
In this activity (page 4), learners work in groups to plan and build large structures using recyclable materials they have brought from home.
Building Tall
Source Institutions
In this engineering activity (page 2 of PDF), young learners investigate how a wide base can make a building more stable. Learners use blocks or boxes of different sizes to construct stable towers.
Shimmering Lenses
Source Institutions
In this activity, learners use Jell-O to explore lenses. Learners cut Jell-O into convex and concave lens shapes and examine how light exits each lens in a darkened room.
Breaking the Tension: Surface Tension 1
Source Institutions
Learners explore how the attractive forces between water molecules create surface tension and allow certain objects to float on the surface of water.
Rolling Returns
Source Institutions
In this activity, learners build a special rolling can that returns back to you when you push it forward. Use this activity to demonstrate the transfer of energy between kinetic and potential energy.
Rubber Band newton Scale
Source Institutions
In this activity, learners make a simple spring-like scale using a rubber band instead of a spring, and calibrate the scale in newtons (N).
Everyday Poisons
Source Institutions
This reading and writing activity (on pages 2-9) teaches what plant parts should be avoided, how a person can get rid of toxins, symptoms of plant poisoning, and how plants create poisons to repel pre
Cryptographic Protocols: The Peruvian Coin Flip
Source Institutions
This activity about cryptographic techniques illustrates how to accomplish a simple, but nevertheless seemingly impossible task—making a fair, random choice by flipping a coin between two people who d
Two-String Yo-Yo
Source Institutions
Learners build a yo-yo using a piece of wood, PVC pipe, and string. In doing so, learners explore the force of gravity and angular momentum.
Creating a Local Field Guide
Source Institutions
In this activity, learners survey living organisms near where they live or go to school, and create a local field guide.
Milk Plastic
Source Institutions
In this activity, learners transform everyday milk into small plastic figurines and jewelry. Use this activity to introduce learners to monomers and polymers.
Blue Sky
Source Institutions
In this optics activity, learners explore why the sky is blue and the sunset is red, using a simple setup comprising a transparent plastic box, water, and powdered milk.
Take It in Stride
Source Institutions
In this health and fitness activity, learners focus on the importance of daily physical activity, specifically walking.
Change in Temperature: Exothermic Reaction
Source Institutions
Learners add calcium chloride to a baking soda solution and observe an increase in temperature along with the production of a gas and a white precipitate. These are all signs of a chemical reaction.
