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,...

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...

A rather simple, but impressive activity is displayed in this Steve Spangler Science video. Dry ice, solid carbon dioxide, is used to create gas-filled bubbles. You can perform this as a demonstration when teaching chemistry classes...

Spangler has a fourth grader join him in this segment. Her science fair project was a demonstration of how biologists cleaned up the birds and other wildlife that were affected by an oil spill. Amazingly, it's as simple as using soap!...

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...

Students 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 during low...

Pupils explore the ingredients and properties of bubbles. They participate in various bubble blowing activities, and write a paragraph describing their best bubble.

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....
