Young scientists learn that seeing isn't necessarily believing when it comes to the states of matter. After performing a fun class demonstration that models the difference between solids, liquids, and gases, children complete a series of...

Creating a definition may be easier than it sounds! Give your classes experience creating their own definition. Scholars examine the meaning of the compact-ness of a scatter plot and create their own definitions based on measurements. 

Don't melt away! Pairs investigate different insulation materials to determine which one is better than the others. Using a low-temp heat plate, the teams insulate an ice cube from the heat source with a variety of substances. They...

Monarch butterfly populations have decreased by 90 percent over the past 20 years due to misuse and ineffectiveness of some pesticides. Given the challenge to increase pesticide safety and effectiveness, the class, through discussion,...

Knowing the basics of drafting allows individuals to create drawings that show all the views and measurements necessary to allow others to visualize the original object. Pupils gain experience by drawing three orthographic views of...

Transform your scholars into mathematicians as they develop their own geometric definition. The task asks individuals to compare cylindrical objects and create a definition for the disc-ness of each object. They may use any method and...

Add a little algebra to the geometry. Class members learn about the Addition Postulate for segments and angles. The pupils use their knowledge of solving equations to find lengths of segments and measures of angles. Individuals apply...

In this third of a twelve-part series, the focus moves from using matrices to solving systems of equations with substitution and elimination, including more than two dimensions and variables in equations, and analyzing statistical data....
