Energy and machines are two things that belong together. This resource provides a clear and simple overview of energy, force, work, and machines. Because the information in this presentation is clear and well-organized it would...

Planning a unit on simple machines? Save some time and energy with this collection of lessons and activities that explores how these devices are used in the real world to make life a little easier. 

Do you think the lab smells like rotten eggs? Sorry to hear about your sulfering. A set of five experiments covers many different topics including seasons, gravity, food, precipitation, and photosynthesis. Though not presented as a...

Planning an elementary science unit has never been simpler! These twelve lessons guide young scientists through an exploration of simple machines and their many uses in the real world before asking them to apply their learning...

Students experiment with Newton's Third Law of Motion. In this physics and motion instructional activity, students complete two experiments to illustrate force and its equal and opposite reaction. Students first work in pairs to exert an...

Force acts on objects in mysterious ways ... until now! A comprehensive presentation explains the balance of forces acting on objects. Learners draw free body diagrams to show these invisible forces and make force calculations.

At the end of a general physics course focused on light and electricity, you can administer this exam. Concepts covered include electromagnetism, circuits, induction, light rays, lenses and mirrors, characteristics of light, electron...

Explore the geometry of treasure hunting! Learners use geometry to design a treasure recovery strategy. The objective is to create a design that minimizes the amount of work required. Budding mathematicians use properties of triangles as...

Where does the energy of an arrow come from? Is it from the person, the bow, or somewhere else? A simulation allows scholars to adjust the stretch distance and the elastic constant in order to understand where the energy comes from, what...

Young geometers become pool sharks in this analysis of the angles and lengths of a trick shot. By using angles of incidence and reflection to develop similar triangles, learners plan the exact placement of balls to make the shot....

Young scholars experiment with a steel ball and matchbox car to find the effects of force and motion. In this force and motion lesson, students assemble a track, conduct experiments and record on a shoot the loop worksheet. Young...

Students focus on a force and motion problem, explore it, reflect on it and apply it while completing experiments.  In this motion lesson, students experiment with force and motion by creating a track for testing cars.  

Young scholars explore the concepts of force and effort by observing simple machines. In this physics lesson, students attempt to sharpen a pencil without any help, bite into an orange with their lips curled over their teeth, and other...

Emerging engineers work in teams to design pipe insulation roller coasters for marbles that meet specific parameters. They are required to label along the track the areas where kinetic and potential energy are highest and lowest, where...

In this work and power worksheet, learners read rules for work and power and answer a set of related questions. Answers are included.

Raise the energy level of your physical science class with this exciting hands-on activity. Applying their knowledge of kinetic and potential energy and Newton's laws of motion, young engineers use foam tubing and marbles to create...

Show your students how to make their work easier. The first lesson in a series of 10 introduces the class to work and the way simple machines can be make work easier. The simple machines scholars can find in everyday items are...

Young engineers consider how to apply accelerometers and sensors to help prevent falls in elderly people. They consider forces of motion and gravity as part of the engineering design process.

Which of the following can you survive without for the longest time: water, food, or a positive mental attitude? The answer may surprise you. Guide learners of all ages through games, activities, and discussions about surviving in the...

A formative assessment is a great tool for planning further instruction. The fifth lesson of a 14-part series exploring magnetism and electricity provides questions to gauge current understanding of magnetic fields, compasses, and...

This PowerPoint is a gem! Seventy-eight slides present an entire introduction to matter in bullet-point fashion. Viewers learn about everything from mass and inertia to phase changes and gas laws! The only glitch is that the links to...

The principles and uses of inclined planes, screws, and wedges are the focus of a science lesson. In it, youngsters come up with every day examples of simple machines, and build an example of one in class. That project is then used to...

Young scholars describe the science of physics. In this Physics activity, students observe examples of physics within their classroom. Young scholars create a definition for physics.

In this energy, work and power activity, learners solve 12 problems about circuits, electric motors, Ohm's Law and electric currents.
