A Feast for Yeast
Source Institutions
In this activity on page 6 of the PDF (Get Cooking With Chemistry), learners investigate yeast. Learners prepare an experiment to observe what yeast cells like to 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.
Condiment Diver
Source Institutions
In this hands-on activity, learners make the world's simplest Cartesian diver, using only a plastic bottle, some water, and a condiment packet.
Defining Dissolving
Source Institutions
In this introductory activity, learners discover that sugar and food coloring dissolve in water but neither dissolves in oil.
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.
Nuclear Fusion
Source Institutions
This simple and engaging astronomy activity explains nuclear fusion and how radiation is generated by stars, using marshmallows as a model.
Iron in Cereal: Find iron in your food!
Source Institutions
Learners investigate an iron-fortified cereal by stirring it with a strong magnet. They discover that metallic iron is present in some cereals.
Self-Assembling Dessert Toppings
Source Institutions
This is an activity (located on page 3 of the PDF under Self-Assembly Activity) about self-assembly, the ability of molecules to assemble themselves according to certain rules.
Marshmallow Models
Source Institutions
No glue is needed for learners of any age to become marshmallow architects or engineers.
Pennies for Pits
Source Institutions
In this math lesson, learners use fruit to learn about proportions and percentages. Learners compare the weights of the edible and non-edible portions of fruit.
Equal Sharing Game
Source Institutions
In this activity, learners are introduced to division and fractions as they share snacks with a group of friends.
Hunger Signals
Source Institutions
This game explores the different reasons we choose to eat, and helps us be aware of when our body needs food and when it does not.
Model Eardrum
Source Institutions
In this activity (last activity on the page), learners make a model of the eardrum (also called the "tympanic membrane") and see how sound travels through the air.
Melts in Your Bag, Not in Your Hand
Source Institutions
In this activity, learners use chocolate to explore how the Sun transfers heat to the Earth through radiation.
Fruit Fly Trap

Pickle Lab
Source Institutions
In this online activity, learners experience the thrill of pickle making, and explore how a cucumber becomes a pickle.
Double or More
Source Institutions
Choose a recipe to double (or triple, quadruple, or halve). Show everyone the recipe and engage them in figuring out: How much will we need to increase the recipe to feed everyone?
Frijolitos
Source Institutions
Esta actividad enseña la proporción y razón por hacer que los aprendices hagan "ensaladas" que combinan tres tipos de frijoles en tres combinaciones diferentes.
Red, White and Blue II Demonstration
Source Institutions
In this chemistry demonstration, learners investigate the rule "likes dissolve likes" by combining three, immiscible liquids to create a colorful density column.
