Eat a Water Molecule

Eat a Water Molecule

We now know what the formula for water looks like. What does an actual molecule of water look like? How can we see something that small? Powerful X-ray machinery allows scientists to predict how the atoms in a molecule look. Let’s build a model so we can see, too.

From The Chemistry of Food

In the kitchen, chefs combine and alter food ingredients to create a finished dish. Some of these changes are physical—the food changes form, shape, and size, but the molecules that make up the food do not change. Other changes in food are chemical. When food undergoes a chemical reaction, a new substance is created. During a chemical change, bonds between molecules are created or destroyed. In this activity, you will classify different changes food undergoes...

Build the Eiffel Tower

Build the Eiffel Tower

From The Science and Technology of Marie Curie

Built in 1889 for the World Exposition, the Eiffel Tower honored the French Revolution. It also showcased national engineering and design expertise to an audience of global visitors. Originally intended as a temporary monument, it remains one of the world’s most visited landmarks. The structure of the tower itself is actually quite simple! To understand how its rivets and beams join, build a model of your own.

Detailed Book Description

You might think people study chemistry only in laboratories or classrooms—but, actually, chemistry is everywhere!

We observe chemical reactions every day. Have you ever watched fireworks? That’s a chemical reaction. Have you ever found sour milk in your refrigerator? Another chemical reaction! There’s even chemistry happening inside your own body as you break down the food you eat into usable nutrients. In Chemical Reactions! With 25 Science Projects for Kids, readers ages 7 to 10 learn about the atoms and molecules that make up everything in our world and what happens when different atoms and molecules come in contact with each other.

Explore chemical reactions through 25 hands-on, STEM activities, fascinating facts, essential questions, links to online resources, and even jokes that help support deeper learning!
