What a Drag!

It's time to crack open that piggy bank and see what's inside. First, count up the pennies, nickels, dimes, and quarters, identifying what fraction of them are dimes. Then calculate the total value of the coins, writing another fraction...

Middle schoolers develop a comprehension of parts per million as a concept. They work in teams to create successive dilutions of a solution to reach a parts-per-million concentration. Students list what they think the atmosphere is made...

Test your class' understanding of free falling objects with a video demonstration that shows two equal weights dropped simultaneously. One hits the ground first, which is contrary to what students understand about the acceleration due to...

Discover the chemistry behind the color change in leaves. The lesson narrator describes how trees must recycle nutrients in the leaves before they fall off for the winter. The video breaks down the process and highlights the chemistry of...

To the bat cave! No, not the one you're thinking of. Part one of a two-part series of expedition videos from playlist on mammals finds a group of researchers from the Field Museum embarking upon a quest. Content includes preparation for...

There is an easier way to share functions among objects. The fifth section of a six-part series on object-oriented design introduces the concept of object inheritance. The coding helps pupils create a base object type that has all the...

Have you ever wondered why scientists use rotten chicken liver? The video explains this and more on a Field Museum trip to a prairie. Brain Scoop presents the first part of their insect adventure as part of the playlist on Insects. 

Do not let friction drag you down! The 11th segment in a series of 22 focuses on the fourth force acting upon an airplane—drag. Pupils learn about the effects and causes of drag.

Groups suspend objects within layers of liquids to determine the densities of different liquids and compare them to the densities of objects calculated in Part 1. The groups then carefully test their calculations by layering the...

The purpose of this activity is to demonstrate how drag affects falling objects. Students will make a variety of shapes out of paper and see how size and shape affects the speed with which their paper shapes fall. They will also be able...
