High schoolers investigate properties of the four centers of a triangle and explore a special property of the circumcenter and orthocenter of a triangle. This instructional activity requires the use of Cabri, Jr.

High schoolers explore the concept of quadrilaterals as they find the midsegments of quadrilaterals using Cabri Jr. on a graphing calculator. They find midpoints, slopes, angles, and distances of lines and angles.

Students identify the factors affecting friction. In this physics lesson, students construct their own rocket car and race them. They graph the average speeds and discuss how lubricants affect friction between rubbing surfaces.

Students identify the various states of water. They use hypothesizing and hands-on experimenting on changing the states of water, the properties of water, and the role of heating and cooling in the changes of state.

Young scholars define and classify all the different ways in which numbers are used in forecasting and coping with the effects of a hurricane. They conduct research to compare and contrast these numbers as they apply to Hurricane Floyd and

Students examine various Halloween traditions and the legend of the Jack O'Lantern. They listen to the story "Pumpkin Pumpkin," examine a map and locate the origins of pumpkins, weigh and measure a pumpkin and graph the results, and...

Eighth graders identify the different stages in the life cycle of a star. In this astronomy lesson, 8th graders read H-R diagrams and analyze data. The describe how the Sun's evolution will affect Earth in the future.

Ninth graders produce a projected, pinhole image of the sun and from measurement of the image and projection distance, calculate the actual size of the sun. They estimate the sun's apparent brightness from different planet.

Beginning geometers use tiles and grid paper to draw and calculate perimeter and area. Rectangles of different sizes are created and then measured to build understanding. The one-inch grid sheet referenced is attached. 

A great way to incorporate math into life science, this lesson has learners measure migratory routes on a map and calculate the actual distance that shorebirds on the routes would cover. Learners compute the distance covered in both...

Here is a hands-on activity where your class members will discover different ways to measure the government's financial situation and work to add data and redraw graphs in order to calculate the ratio of gross federal debt held by...

Boundaries are important in relationships, no matter how close the relationship is. Middle schoolers explore the ideas of boundaries and personal space with two units about relationships. After discussing the boundaries in their own...
