Chemical or Physical?

Chemical or Physical?

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 during cooking as either physical...

Eat a Water Molecule

Eat a Water Molecule

From Chemical Reactions!

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.

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.
