Here is an inventive plan that should get your young scientists excited! In it, groups of pupils test out the work done by six different simple machines. The machines are: the wedge, the lever, the inclined plane, the pulley, the screw,...

Youngsters are introduced to the basic principles and uses of the wheel and the axle. They come up with every day examples of simple machines and look into why the wheel and the axle are best-used as a paired machine instead of used...

The lever is an everyday simple machine. Youngsters learn the principles of levers and explore their many uses. Groups of pupils perform a simple lab where they lift objects with a fulcrum while placing the load in a variety of...

The principles behind pulleys, levers, and simple machines are the focus of a science lesson. In it, learners take part in a whole-class activity. There are two groups of pupils who each must lift objects with fixed pulleys and multiple...

Help your students remember math tricks and rules. Review working with positive and negative numbers, decimals, and the order of operations in this engaging presentation.

Teach the concept of simple random sampling through an interactive lesson. Learners explore the concept by considering the strength of sampling methods. Size of the samples varies also as individuals determine which methods lead to the...

Mathematicians manipulate a mountain of money to solve six questions about simple interest. Question types include several multiple-choice and one discussion. 

Young mathematicians research and discuss real world math word problems and ways in which they apply math concepts in their everyday lives. They create a storyboard of a math word problem from which they create a slide for a multi-media...
