Let's Make Music
Source Institutions
In this activity, learners will create their own percussion instrument with recycled materials. Learners will explore design, fabrication, cause and effect and sound through this activity.
Where on Earth?
Source Institutions
Learners look at labels on items in the room to determine where each item was manufactured, then write about the item on an index card.
Pop Can "Hero Engine"
Source Institutions
In this activity, learners build water-propelled engines from soft drink cans.
Roller Coasters
Source Institutions
In this design challenge, learners will create their own roller coaster using household objects for the track and a marble or small ball as their cart.
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.
Solar System on a Stick
Source Institutions
Learners build a model of the planets in the solar system. In their model, the planets are spaced in their relative distance from the Sun.
Mating Game
Source Institutions
In this game (on pages 14-21), learners explore how each human being inherits genetic traits such as eye color.
Spice World
Source Institutions
In this activity, learners create a map showing the origins of spices and herbs from a favorite recipe(s). Learners first research the origins of the ingredients and then locate them on a world map.
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.
Frog Olympics
Source Institutions
Did you know that a bullfrog can jump a distance of 10 times its body length? Learn more about nature's most acrobatic amphibian, the frog, through this set of short, hands-on activities.
Build a Bridge
Source Institutions
In this activity, learners use design thinking to design and build their own bridge out of household materials including adhesives and/or connectors.
Recycling Paper
Source Institutions
In this crafty chemistry activity (on page 2 of the PDF), learners make their own paper from used paper they may have otherwise thrown away.
Water Motor
Source Institutions
In this physics activity (page 10 of the PDF), learners will explore how energy from moving water can be used.
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.
Windmills
Source Institutions
In this physics activity (page 8-9 of the PDF), learners will explore wind energy. They will build their own windmill and see how energy from wind can be converted into a useable form.
Geodesic Gumdrops: Candy and Toothpick Architecture
Source Institutions
This hands-on activity shows you how to build basic architectural shapes out of toothpicks and gumdrops.
Blowin' in the Wind
Source Institutions
In this weather activity, learners build their own wind detector and test for the presence of convection currents in their indoor location.
