Rainbow Density Experiment
Source Institutions
In this colorful activity (page 6 of the PDF), learners will make a multicolor density column by using different concentrations of sugar solutions.
DNA From an Onion
Source Institutions
In this genetics activity, learners extract DNA from an onion, using detergent solution, a food processor, and rubbing alcohol. They will also discuss genetic engineering of plants.
Rice Handle
Source Institutions
In this physics activity, learners attempt to lift a jar full of rice using only a spoon.
Spaghetti Bridge
Source Institutions
In this engineering activity, learners investigate the differences between the strength of bridges made from flat and round building materials.
Checking For Starch
Source Institutions
In this chemistry activity (page 3 of the PDF), learners will observe a chemical change, specifically what happens to iodine when it is applied to ripe and unripe apples.
Wrap It Up!
Source Institutions
In this Energy and Environment activity (page 9 of the PDF), learners calculate the mass of a piece of gum, compare it to the mass of the gum's packaging, and then create a bar graph of the results.
Light Combinations
Source Institutions
In this activity about magnetism (page 17 of the pdf), learners experiment with magnets, exploring the concept of diamagnetic materials by seeing how a grape reacts to a magnetic field.
Cabbage Indicator
Source Institutions
In this fun chemistry activity (page 3 of the pdf), learners use cabbage juice to determine the pH of several substances.
Spit Test
Source Institutions
In this biology activity (page 8 of the PDF), learners will explore how saliva assists in the beginning of the digestive process.
Peanut Butter and Jelly Robot
Source Institutions
This is an activity about robotics programming. Learners will discover how precise programmers have to be as they instruct a friend to make a peanut butter and jelly sandwich.
Comparing Crystals
Source Institutions
In this chemistry activity (page 3 of the PDF), learners will learn about crystals by growing their very own.
Chemical Reactions in Your Mouth
Source Institutions
In this chemistry activity (page 5 of the PDF), learners will see that chewing is more than just the crushing up of food; there is actually a chemical change going on at the same time.
In Proportion
Source Institutions
Through this nutrition activity (page 5 of the PDF), learners will understand—and probably be surprised by—how big serving sizes of various foods should be.
Rock Candy
Source Institutions
In this yummy chemistry activity which requires adult supervision, learners use sugar and water to explore how crystals form.
Ice Cream Freeze
Source Institutions
In this fun and delicious chemistry activity (page 1 of the PDF), learners will explore the difference between physical and chemical change by making homemade ice cream.
Breathing Yeasties
Source Institutions
In this life science activity (page 8 of the PDF), learners explore the carbon cycle by mixing yeast, sugar and water.
Eggshell Inertia
Source Institutions
In this physics activity (page 14 of the PDF), learners gain a better understanding of how friction and mass affect objects by comparing the rotational inertia of raw and hard-boiled eggs.
Chocolate Lava
Source Institutions
In this yummy earth science activity (page 5 of the PDF), learners use fudge to learn about different kinds of lava.
Edible Ink
Source Institutions
In this chemistry activity (page 6 of the PDF), learners observe a chemical change. Learners write and reveal a secret message using edible ink.
Sugar/Salt Crystals
Source Institutions
In this chemistry activity (page 1 of the PDF), learners will observe a physical change.
