Buoyancy Boats
What did the sea say to the boat? Nothing, it just waved. An inquiry-based lesson starts with a simple concept on the Archimedes Principle and challenges pupils to make something out of clay that floats. Then, they design...

Earth as a System
Ecosystem, human body system, weather system. We hear the word system a lot, but what does it really mean? In the activity, pairs or groups of learners discuss how a bicycle is a system and then analyze objects in their classroom and...

Does Temperature Affect Dissolving?
When making sweet tea, why do people dissolve the sugar in hot tea instead of cold tea? The class discusses the previous lab and builds upon it. Working in groups, they design an experiment to determine how temperature affects the...

Determining the Nature, Size, and Age of the Universe
Prompt scholars to discover the expansion of the universe themselves. Using photographs of other galaxies, they measure and then graph the size and distance of each. Finally, they draw conclusions and prove the universe is...

Century Timeline
Scholars use the Cosmic Times and the Internet to create a timeline of events from 1916 when Einstein presented the Theory of General Relativity to 2016. Scientific discoveries are the main focus, then pupils add in events from culture,...

Things Are Not Always What They Seem
Science is magic that works. Magical color-changing beads and a coffee can that follows voice commands are just two examples of magic tricks that rely on science. After completing a hands-on activity and an experiment investigating the...

Expanding the Universe
When Einstein first heard the theory of the expanding universe, he dismissed it as bad physics. Now scholars learn about the theory and how scientists prove it has merit. Through a hands-on simulation and videos, class members measure...

Heat, Temperature, and Conduction
How does heat move from one item to another, even when the items are in different states of matter? Pupils experiment with adding washers to hot water and adding hot washers to room temperature water to observe the heat transfer.

Carbon Dioxide Can Make a Solution Acidic
Can your breath change the acidity in a liquid? A lesson begins with a demonstration that proves it can. Then scholars perform an experiment to determine if other gases can change the pH of liquids. Finally, they research how this...
