Young scholars observ the cooling and warming of room temperature, hot, and ice cold cans of water by measuring the change in temperature over time. They then attempt to develop explanations for the observations made and apply their...

Students determine the density of different substances. In this physical science lesson, students rank them according to their density. They discover the relationship between volume and density.

Third graders use a Slinky, rubber bands, paper, coins and cups to experiment with weight and its relationship to gravity. They discuss their results and develop a consensus on conclusion statements derived from their experiments.

Eighth graders perform experiments with simple machines and write up the results. They research the construction of the step pyramid and the three pyramids at Giza. Students research how the ancient Egyptians used simple machines in...

Students using clay and a toothpick, shape the clay into a "mountain" upon which they make a road that is the shortest in distance. They measure the length of their road and then make a road that is the longest in distance without...

Students research and experiment to discover the lifting power of helium gas.

Third graders observe and discuss examples of friction. They discuss what experimentally increases and decreases friction. They then predict which surface will produce the most friction and verify the prediction.

In this Guy Fawkes instructional activity, students cut apart 8 sentence strips; each tells an event in the life of Guy Fawkes. Students put them in the right order, paste them on a paper, and illustrate each event.

Students estimate how many children in their class it would take to equal the mass of one adult bear. They then weigh and record their measurement on a chart to check their estimate.

Students compile and analyze data pertaining to College Credit AP Exams. They pose questions - Which exam is the easiest? - determine answers from their data and display their results.

Explains how a spring scale works and what it is used for.

Students learn about the engineering design process as they design, build, and test a spring scale using everyday items that can measure the weight of an apple. The objective of the activity is to explore how scales work and to learn...

Students will discover the scientific basis for the use of inclined planes. They will explore, using a spring scale, a bag of rocks and an inclined plane, how dragging objects up a slope is easier than lifting them straight up into the...

With a simple demonstration activity, young scholars are introduced to the concept of friction as a force that impedes motion when two surfaces are in contact. Then, in the Associated Activity (Sliding and Stuttering), they work in teams...
