Electrical engineers entertain and explain how to construct an electromagnet-driven motor. Kellie and Mike, the hosts of the show, are enthusiastic teachers that will help introduce a project that you likely include in your middle school...

Mike and Kellie, a team of electrical engineers, demonstrate how to to design a contraption that accurately drops a marble onto a target. The materials needed and general instructions are provided on the website or via a downloadable...

Very simply, geometers examine a pair of rectangles on graph paper and find a translation and rotation to demonstrate their congruence. A couple of questions follow to stimulate critical thinking about other possibilities.

Which vase holds more water: a cylinder, sphere, or cone? Figure out which should be used for your sister's birthday bouquet with this practical word problem.

Provide your class some practice with the dimensions of geometric figures. Here you have a set of three different-shaped, stemmed drinking glasses with diameters and heights provided. Math-minded individuals calculate the volume of each....

The task at hand is to partition a hexagon into two, four, and eight congruent figures. Make sure to give your wizards a sheet of triangle grid paper on which to decompose the hexagons. Have them explain which rotations, reflections, or...

Use the handout as guided or independent practice in drawing a reflection of a rectangle over a line. Three rectangles are provided for practice in addition to a critical thinking question.

A triangle, square, hexagon, and circle all have a perimeter of one unit. Eighth graders must attempt to find the area of each and arrange them in order from least to greatest areas. A terrific task for applying four different...

A quadrilateral is drawn on the coordinate plane, and eighth grade geometers find the length of each side and the diagonals by applying the Pythagorean theorem. 

Everyone wants to have the biggest snow cone possible, so would that be in cone-shaped cup or a more cylinder-style cup? Hungry geometry juniors compute the volume of each in this practical task.

The task, should your class decide to take it, is to list a series of reflections that transfer a line segment from one position to another. 

Selective breeding has resulted in some novel and beautiful or useful dogs over the years. Using the American Foxhound as an example, genetics learners find out how and why they came about. Then, in small groups, they select breeds to...

Incorporate reading strategies, math, research, and the scientific method into one lesson about water conservation. After reading a story about a landlady trying to determine how many people are living in an apartment, learners develop a...

With the global temperature on the rise, the effects of climate change are starting to be seen. However, many people have a difficult time conceptualizing the long-term effects, such as sea levels rising. Given an easy and effective...

Meteorologists view an animated video by the Environmental Protection Agency to learn how the carbon cycle works, and then move into groups to analyze and graph actual data of the atmospheric carbon dioxide concentration from Hawaii's...

This well-organized lab activity introduces earth science pupils to the greenhouse effect. They will set up two experiments to monitor temperatures in an open jar, a closed jar, and a closed jar containing water. Ideally, you would have...

Build a class community, allow time for in-depth reflection and research, and facilitate the learning and writing process with online discussion boards! A resource delves into the benefits and purposes of discussion boards, as well as...
