Each of the slides here gives a definition, equation, or calculation example for a component of force and motion. This large collection covers topics from momentum and Newton's laws to centripetal forces and simple machines. Animations...

Youngsters are introduced to the basic principles and uses of the wheel and the axle. They come up with every day examples of simple machines and look into why the wheel and the axle are best-used as a paired machine instead of used...

While architects and engineers don't often build with plastic straws and foam board, the same principles still apply. Challenging both the creativity and critical thinking of students, this engaging design project is perfect...

In this force and acceleration activity, students solve 3 problems about moving objects, the forces working against them, the mass and their acceleration. Students determine if 6 statements about a falling elephant and a falling feather...

Students identify the factors affecting friction. For 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.

In this weight worksheet, students review the equation for solving for the force of weight and review the kinds of friction. Students complete 10 matching, 7 fill in the blank, and 8 problems to solve.

In this mass worksheet, students fill out a two column notes sheet about mass. Students fill in short answers for 17 places in the notes sheet.

Students experiment to find which liquids are more dense.  In this density and mass lesson, students predict and then test objects to observe and measure their density. students observe which items sink and float. Students complete...

Second graders identify three forms of matter- solids, liquids, and gases with 100% accuracy. They observe what happens when they try to put two kinds of matter into the same space and conclude that solids, liquids, and gases occupy space.

Students use graph paper to construct a graph and determine the slope of a straight line. They determine the weight (mass) of paper clips with a pan balance. Pupils weigh an unknown number of paper clips, and to interpret the graph to...

Fifth graders build objects using various materials. They estimate the weight of the object using individual building pieces. Then they weigh the actual object and then tear it apart and weigh the pieces. They compare the two weights.

In this isotopes worksheet, learners calculate an average atomic mass of specific elements. This worksheet has 4 problems to solve.

In this the force rule activity, 10th graders read explanations and examples, then fill in 5 blanks and answer 10 short answer questions about force, with answers included.

Students make generalizations about weight and mass by engaging in two hands-on experiments. In this weight and mass lesson plan, students weigh both an empty beaker and beakers with various amounts of weight inside of them in order to...

Students measure how much mass is worn away during 15-20 minutes of shaking. They shake rocks for 15-20 minutes to simulate stream erosion. Students listen to music as they shake their rocks. They weigh out 100 grams of marble chips....

Investigate the Law of Conservation of Mass through a lab exploration. Individuals combine materials to initiate chemical reactions. They monitor for signs of reactions and measure the masses before and after the reactions for...

Is your class struggling with Newton's Second Law? Then show them a presentation that covers everything physics scholars need to know about forces. Starting with gravity, the slides focus on Newton's Laws of Motion, and end with an...

Studies show that obesity is now a global problem. But how are researchers measuring obesity? Young scientists investigate the myriad of methods for measuring body fat through a presentation. From hands-on to high-tech, viewers learn...

Applying this metric worksheet, mathematicians will provide standard metric units of measurement, identify the largest and best way to measure items using the metric system, and convert units using King Henry.

The Law of Conservation of Matter can be complex for young scientists to fully grasp. Use this experiment to help simplify the process as pupils perform two experiments to determine mass: one that melts a substance and the other that...

Augment your math curriculum with posters detailing several concepts important to second grade math. Each poster features one math term from geometry, measurement, probability and statistics, computation and estimation, numbers and...

Do domed structures have advantages over their less-than-spherical counterparts? Junior architects explore the pros and cons of domes through a design challenge. Teams work together to plan, sketch, build, and test domes created from an...

Model and explore osmosis using squash and potatoes. Young scientists expose chunks of potatoes to different concentrations of a squash solution. They compare the weights of the chunks before and after exposure to the solution and use...

The tension of the 236 strings in a grand piano exert a combined force of 20 tons on the cast iron frame. The presentation includes topics such as work, forms of energy, conservation of energy, gravitational and elastic potential energy,...
