Taste Match Game
Source Institutions
In this activity (3rd activity on the page), learners taste test different foods and categorize them as sweet, bitter, sour, or salty. Learners compare their results with the group.
Touch Down
Source Institutions
In this design challenge activity, learners build a shock-absorbing system that will protect two “astronauts” when they land.
Glowing Tonic
Source Institutions
In this sunny day activity, learners compare how a cup of water and a cup of tonic water reflect or refract light in the sun.
Chocolate (Sea Floor) Lava
Source Institutions
In this edible experiment, learners pour "Magic Shell" chocolate into a glass of cold water. They'll observe as pillow shaped structures form, which resemble lavas on the sea floor.
Grow Rock Candy
Source Institutions
Learners grow sugar crystals (rock candy). They make a hot solution that has an excess of sugar dissolved in it, then as the solution cools, they see sugar crystals form.
Moo Glue
Source Institutions
Using a milk-based recipe, learners create "moo glue" which is basically white school-type glue. The "secret ingredient" in milk that helps make glue is a chemical called casein.
Leaning Tower of Pasta
Learners build structures from spaghetti and marshmallows to determine which structures are able to handle the greatest load.
Ice Cream
Source Institutions
In this chemistry activity, learners use the lowered freezing point of water to chill another mixture (ice cream) to the solid state.
Toast a Mole!
Source Institutions
In this quick activity, learners drink Avogadro's number worth of molecules - 6.02x10^23 molecules!
Candy Chromatography
Source Institutions
Learners analyze candy-coated sweets using chromatography. Learners use this method to separate the various dyes used to make colored candy.
Bake Ice Cream in Your Oven
Source Institutions
In this a hands-on activity, learners explore how to put ice cream in an oven without it melting. Ideas in this activity include insulation and cooking.
Curious Crystals
Source Institutions
Learners carefully look at four known household crystals.
Potato Straw
Source Institutions
In this physics demonstration, learners are challenged to insert a straw the furthest into a potato.
Gelatin Used for Drug Delivery
Source Institutions
In this activity, learners discover how gelatin can be used as a medium for drug delivery. Learners create colored gelatin and then cut out pieces of the gelatin to simulate medicine (pills).
Build a Super Structure
Source Institutions
In this activity, learners use things from the kitchen as building materials to explore how shapes contribute to the strength of different structures.
Smell the Difference
Source Institutions
In this two-part activity, learners use household items to smell the difference between some stereoisomers, or molecules which are mirror images of one another.
Create a Pasta Population Map
Source Institutions
Learners work as a group to create a map of their community. They use pasta to represent people, and glue the pasta on their maps to show areas of large population.
A Simply Fruity DNA Extraction
Source Institutions
In this activity, learners extract DNA from a strawberry and discover that DNA is in the food they eat.
Cool It!
Source Institutions
In this fun hands-on activity, learners use simple materials to investigate evaporation. How can the evaporation of water on a hot day be used to cool an object? Find out the experimental way!
Light Soda
Source Institutions
In this activity, learners sublimate dry ice and then taste the carbon dioxide gas.
