A Whole New World: The Search for Water
Scholars find Earth won't support humans much longer and need to identify a planet with water to inhabit. They test four unknown samples and determine which is the closest to water. Then they explain and defend their results.

Can Gases Dissolve in Water?
Why does soda fizz when opened? Learners discuss the appearance of bubbles in soda bottles when opened. In groups, they design and complete an experiment comparing the amount of carbon dioxide dissolving in cold versus hot liquids.
American Chemical Society
Changing State: Melting
Dry ice is extremely cold — it is -109.3°F or -78.5°C. Scholars observe and explain the molecular motion associated with melting. Then they design their own experiments to speed up the melting process. Finally, a teacher presents a...

Changing State: Freezing
There are five types of frost: ground frost, air frost, hoar frost, glaze, and rime. Scholars mix ice and salt in a metal container to observe frost forming on the outside of the can. Animations and videos enhance the learning.

Why Does Water Dissolve Sugar?
Did you know that if you wait long enough, the M on the outside of an M and M will float to the surface when submerged in water? Learners observe the sugar coating of an M and M while it is dissolving in water. They explain how this...

Changing State: Condensation
When you have a cold drink and you notice the water forming on the outside, it is literally pulling the water from the surrounding air to form the condensation. After watching a demonstration of condensation forming on a glass,...
SRI International
Nanofiltration
How can everyone in the world have access to clean drinking water? Throughout the lesson, learners read about and listen to how water is filtered, what the filtration process removes, and the best ways to filter. They explore the...

The Importance of Food
Pupils make observations while eating food. They act out the process of food breaking down in the body and the roles of various chemical components, such as sugar and protein. It concludes with an activity illustrating the process and a...
Journey Through the Universe
Where to Look For Life?
Every year we discover new planets including more than 1,000 in 2016 alone. Will we ever find life on another planet? The lesson includes two activities to help scholars understand this concept. First, they analyze the temperature range...

Global Water Supply Middle School Curriculum
We take a steady shower stream and clean drinking water for granted, but in many countries around the world, the lack of water or a clean water supply is responsible for higher sickness and death rates. Taking a closer look at the water...

Demonstration of Water Pollution
In this teacher-led demonstration, your young environmentalists will observe and record how different types of water pollutants look when they are combined. From here, individuals will develop a hypothesis on how the water can be...
