Make a Planetary Exploration Balloon
Balloons aren't just for parties! An inquiry-based lesson explores the idea of using balloons for space exploration. Learners become engineers as they attempt to control the ascent and descent of a helium balloon using different masses.
Las Cumbres Observatory
Plotting a Supernova Light curve
Supernovas burn for a short time but can give scientists extensive information about the universe. Learners analyze given data about the change in the light magnitude of a supernova. They look for patterns in the data and use them to...
PHET
Equality Explorer: Two Variables
Solving equations in two variables can't be that much harder than solving equations in one variable. Using a balance interactive, scholars solve equations in two variables. They apply inverse operations by adding -x, -y, or -1 as...
PHET
Equality Explorer
Find the right balance between concrete and abstract thinking. After using interactive balances to explore inverse operations, learners solve multi-step equations with variables on both sides. Of course, they can still use the...
PHET
Equality Explorer: Basics
Not all interactives are made equal. Scholars use an interactive balance to explore the concept of equality. They place different objects on balances to determine the number of each object needed to balance the scale.
