Bubble and Boyle

Even middle schoolers still enjoy experimenting with bubbles! They execute a series of experiments enabling them to distinguish between convex and concave surfaces, explore the properties of buoyancy, surface tension, and density,...

You have to crack a few eggs to make a good engineer! Working in small groups, young scholars design, build, and test devices that protect an egg from breaking when dropped from a ladder.

Young scholars identify the different requirements for photosynthesis to take place. In this space science instructional activity, students simulate conditions in Saturn to investigate if photosynthesis is possible there. They use data...

Where does bad light end up? In a prism! The presentation covers light, mirrors, lenses, and the structure of the eye. It also provides explanations of reflection, refraction, concave and convex mirrors and lenses, and a comparison of...

The thinking, and science, behind hydrogen-powered cars is beautifully demonstrated in this episode. Spangler shows how, by itself, oxygen is not combustible. However, when some hydrogen gas is added, that changes! His assistant scoops...

What do Newton's Law of Gravitation and the moon's orbit have in common? Assist pupils as they view a short video segment and learn the gravitational methods of the moon and earth. They learn the reason why and how these have changed...

Young scholars study a way to quantify the process of photosynthesis during a given time using the Elodea plant. They design a hypothesis that they test in the hands on activity. They compare the amounts of photosynthesis that occur...

Students conduct an experiment to determine the percentage of sugar in various types of gum. They weigh the gum after chewing it to determine the amount of mass lost from each piece of gum, analyze the data, and create a graph of the...

How does a telescope magnify images? Learners first watch a tutorial explaining the basic construction of a telescope. Then they interact with a simulation that allows for changes in the location and diameter of the reflecting mirrors....

In this law of action and reaction learning exercise, students build a bubble powered rocket using a film canister, paper and effervescing tablets to create bubbles inside the canister of the rocket. The pressure inside causes the...
