Twelfth graders examine the misconceptions of Newton's laws of motion.  In this motion and gravity activity students interpret data and see the effects of gravity. 

Middle schoolers study the planet Mercury and develop an understanding of the planet's composition, geology, and other important characteristics. They explore a Web resource on the planet Mercury which is the central focus of this lesson...

Students distinguish between weight and mass. They examine how in oscillations of a mass against an elastic spring--in the absence of gravity, or in horizontal motion--the length of the oscillation period is proportional to the square...

Students explore how the amount of sunlight and heat change in areas that are shaded.

Students, in groups, collect and analyze samples of native grassland plants near and around a road to show how roads have an impact on surrounding habitat.

Students study the difference between horns and antlers. They identify animals who have each and draw pictures of these animals. They experience samples of actual horns and antlers.

Students research and analyze sound waves and how an ultrasound works to image a baby in utero. They explore various websites, complete worksheets, and write a paragraph describing a demonstration they view in the classroom.

Students explore natural selection and its influence on the populations to fine tune traits and characteristics. The acquisition of traits developed out of need is examined through a game played in class.
