Carbon Dating

How old is that fossil in the window? In this BrainPOP movie on carbon dating, Tim and Moby will teach you about how scientists use a radioactive isotope called carbon-14 to find out the answer! Learn about key terms like half-life, radioactive decay, and radiometric dating and what they all mean! You’ll also see how you can tell when a fossilized animal died by comparing the amount of carbon-14 that would have been in a living creature to the amount that’s left in the fossil. Carbon dating is cool!

Earthquakes

Did you feel that? Earthquakes can be so small that you can barely feel them — or they can be so strong that they topple buildings. In this BrainPOP movie, Tim and Moby introduce you to the mechanics of earthquakes. They’ll tell you why earthquakes happen and what plates, faults, and waves have to do with it all. You’ll learn why the crust of the earth isn’t as stable as it seems; what can happen on a fault line; and the names for the three types of seismic waves. You’ll also find out how scientists use seismographs to measure the strength of earthquakes. Take cover!

Avalanches

Headed off for a ski trip? Uncover the secrets of the mountains as Tim and Moby introduce you to the terrible power of avalanches. In this BrainPOP movie, you’ll discover how avalanches form and what makes them so destructive. Learn how the forces of stress and strength determine whether a mountain’s snowpack stays stable, and what happens when something disturbs that delicate balance. Discover what keeps a slab of snow in place on a mountainside, and what can make that same slab unstable. Finally, meet the “avalanche triangle,” and see what special property of snow can help it adjust to all sorts of situations. Go ahead and strap on those skis--just watch out for the slabs!

Photosynthesis and Respiration

Everyone needs to eat, right? In this BrainPOP movie, Tim and Moby will teach you the basics about photosynthesis and respiration. You’ll learn why it’s important to know that plants are producers and humans are consumers. You’ll get familiarized with how plant and animal cells convert food into energy, as well as how they create and break down glucose. Discover what plants use their roots and leaves for, and how their chloroplasts work. And you’ll see where in the cell respiration takes place, and what role mitochondria play in producing carbon dioxides, water, and energy. Dinner is served - for plants, that is!
