Fifth graders discuss ways to move large rocks. They relate this to building a rock garden, and the ways people might load boulders into a truck. Students discuss the use of a ramp vs. lifting the boulder straight up onto the bed of the...

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.

Students identify the concepts of density, mass, and volume that define the property of a substance. They also determine that the properties of materials, such as, density and volume, can be compared and measured by using rulers,...

Students measure frictional force existing between a moving cup and the surface it slides on. They conduct the experiment and answer discussion questions.

High schoolers are able to explain why football running backs benefit from having a lower center of gravity when opponents are trying to tackle them. They explain why racing cars are designed to have a low center of gravity. Students...

High schoolers view a video that presents the biogeochemical cycle of nitrogen. They compare types of soils and consider how different fertilizers affect soil composition.

In this transformation worksheet, students identify a series of transformations and sketch them. They use inversion mapping to establish a one-to-one correspondence between nonzero points. This four-page worksheet contains...

In this linear transformation learning exercise, students find a series of linear transformations and sketch them. This four-page learning exercise contains approximately six problems.

Student identify the three stationary positions, on the Earth, on the Moon, and in a house floating atop the cloud layers of Jupiter. They also identify the three orbiting positions, orbiting the Earth, orbiting the Moon, and orbiting...

Students discussion frictional force, kinetic friction, and static friction and the role each plays in acceleration and velocity in relationship to a car and the road on which it is traveling. Students complete lesson answering review...

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...

Third graders demonstrate that gravity is a force.

Pupils discuss Newton's 2nd and 3rd laws using the example of a football linebacker and a small child pushing against each other on an ice rink. Students are able to visualize the results of the push and link it to the laws. Discussion...

Young scholars use inquiry and observation to explore Newton's third law of motion: for every action there is a reaction. For this physics lesson, students rotate through six stations set up with materials and picture directions...

Students make observations about mealworms using hand lenses, rulers, and cotton swabs. Students complete their own mealworm observation chart, then they share their observations with the class. This is one station out of five in an...

Students classify rocks into groups after they observe the rocks and identify properties that can be used to divide them into groups. They then identify other properties that could be used to classify other objects into groups.

Students will make a circuit on a mystery card. They will connect wires, bulbs, and battery to form an electrical tester. After students learn how to make one following the directions, they can create their own mystery card by...

Students make a circuit on a mystery card. They then use an electrical tester to determine where electricity flows between circles on the card. They will connect wires, bulbs, and a battery to form an electrical tester.

Learners test their knowledge of electrical conductors and circuits by constructing an electric tester and using it to determine where electricity flows between circles on a mystery card.

Students determine the temperature of the water in a cup, measure the length of a piece of cardboard, and measure out an appropriate volume of water. This task assesses student's abilities to perform measurement and reporting skills.

Students investigate test scores taken to obtain academic strengths and weaknesses. They practice looking at the scores in order to interpret the results. Students use time for class discussion and planning study strategies to target...

Students simulate block and tackles to lift heavy objects. They lift cargo by hand with the whip and the two-fold purchase to simujlate what crew members do aboard ships. They measure the effort and distance pulled for a gun tackle, luff...

Students determine the density of metal shot by a graphical method using significant digits in making measurements and calculations. Students graph a seris of laboratory measurements and determine density from a mass verses volume graph.

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...
