Round, Light and Hollow
Source Institutions
In this activity about bones (page 12 of PDF), learners investigate and compare the weight-bearing capacity of solid and hollow cylinders.
Try Growing Your Own Mold
Source Institutions
This is a hands-on activity that uses bread and household materials to grow mold. Learners collect dust from a room, wipe it on food, and contain it. One to seven days later, mold has grown.
All Mixed Up!
Source Institutions
In this activity, learners separate a mixture of pebbles, salt crystals, and wood pieces. They add water and pour the mixture through a strainer.
Squidgy Slime
Source Institutions
In this chemistry activity, learners transform two ingredients (4% polyvinyl alcohol solution and 4% borax solution) into gooey slime.
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.
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.
Dangling Magnet
Source Institutions
In this activity about magnetism (page 13 of the pdf), learners will experiment with magnets to explore how water and other liquids affect the strength of magnetic fields.
See the Colors in Leaves
Source Institutions
Learners use chromatography to separate and analyze the mixture of pigments in leaves. Use this activity to discuss photosynthesis as well as why leaves change color in autumn.
Dye Detective
Source Institutions
Learners use filter paper and water to analyze six different markers. They mark the paper with ink, and dip the paper in water. The water travels up the paper and dissolved ink travels with it.
Static Shock!
Source Institutions
In this hands-on activity, learners explore static electricity through the use of common household products. They also explore the connection between static electricity and cold weather.
Do Plants Need Sunlight?
Source Institutions
In this activity, learners find out what happens when they cover leaves with pieces of black construction paper. This activity shows learners that plants need sunlight to survive.
Dusted!
Source Institutions
Learners press their fingertip onto a clean Plexiglas sheet. The fingerprints are then revealed as learners dust over the print with fingerprint powder.
What's in the Water
Source Institutions
"What's in the Water" lets participants use tools to solve the mystery- what chemicals and compounds are in a sample of water?
Flinker
Source Institutions
In this activity, learners make a foam packing peanut "flink"--neither float away nor sink--in water. Learners experiment with materials to make a Flinker that "flinks" for 10 seconds.
Take Me to the (Magnet) Races
Source Institutions
In this activity about magnetism (page 11 of the pdf), learners will experiment with magnets to explore how opposite poles attract and similar poles repel in magnetism.
Hot Spoons
Source Institutions
In this physics activity (page 2 of the PDF), learners will explore the concept of thermal conductivity and learn the differences between high and low thermal conductivity.
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.
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.
Paper Whites
Source Institutions
Learners observe different paper samples under ordinary room light and under a black light to learn some of the chemical differences between different types of paper.
