Making Recycled Paper
Source Institutions
In this activity on page 11 of the PDF, learners follow simple steps to recycle old newspaper into new paper.
Solve The Fall
Source Institutions
In this twist on a classic design challenge, learners will try to stop a bouncy ball from bouncing as they explore how to control the fall of an object.
Copper Cleanup
Source Institutions
In this hands-on experiment, kids use chemistry to explore whether acids or bases are better at restoring a penny’s shine.
Cauldron Bubbles
Source Institutions
In this activity, learners mix up a bubbly brew and examine density. Learners explore how they can make different materials fall and rise in water using oil, water, and salt.
Matter of Degree
Source Institutions
In two separate bags, learners mix water with Epsom salts and detergent.
Thaumatrope
Source Institutions
In this activity, learners make an optical illusion toy from the 1800s to explore persistence of vision.
Exploring Properties: Surface Area
Source Institutions
This hands-on activity demonstrates how a material can act differently when it's nanometer-sized.
Make Pan Pipes
Source Institutions
This is a simple activity for learners to create a traditional musical instrument. Pan Pipes have developed all over the world in different cultures, from South America to Greece and China.
Zipline
Source Institutions
In this design activity, learners create a vehicle that can transport a load, like a favorite toy or as a recycled object, from the top of a zipline to the bottom using only gravity.
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.
Glitter Slime
Source Institutions
Our bodies defend themselves in many different ways to prevent us from getting sick.
Exploring Fabrication: Self-Assembly
Source Institutions
In this activity, learners participate in several full-body interactive games to model the process of self-assembly in nature and nanotechnology.
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.
What am I?
Source Institutions
In this activity, learners examine nanoscale structures of common things.
Iodine Investigators!
Source Institutions
In this activity on page 7 of the PDF (Chemistry—It’s Elemental), learners use iodine to identify foods that contain starch.
Changing Colors
Source Institutions
In this activity, learners will explore how different colors of lights interact with objects around them. Will a blue object stay blue with a red filter?
Photosynthesis and Transpiration
Source Institutions
In this activity on page 7 of the PDF (Plants—The Green Machines), learners examine the effects that light and air have on green plants.
Gumdrop Dome
Source Institutions
In this engineering activity, learners construct sturdy geodesic structures out of gumdrops and toothpicks. Use this activity to explore engineering principles as well as sturdy shapes and triangles.
Balloon Rockets
Source Institutions
In this activity, learners will create a model rocket out of an inflated balloon attached to a straw on a taught string.
