Learn about the conservation of energy at the skate park! Build tracks, ramps, and jumps for the skater. View the skater's kinetic energy, potential energy, and thermal energy as they move along the track. Measure the speed and adjust the friction, gravity, and mass.

Learn about conservation of energy with a skater dude! Build tracks, ramps and jumps for the skater and view the kinetic energy, potential energy and friction as he moves. You can also take the skater to different planets or even space!

Learn about conservation of energy with a skater gal! Explore different tracks and view the kinetic energy, potential energy and friction as she moves. Build your own tracks, ramps, and jumps for the skater.

This lesson plan is for a multi-class period project where student groups plan and create their own videos highlighting different forms of public energy production. This is part of an Energy Conservation unit in HS physics, but could be adapted for junior high students.All resources are the original work of the author. Sound effects and musics in the Producing Your Energy Video instructional video provided free of charge in Adobe Rush.

In this fun optics activity, learners explore principles of light, reflection (mirrors), and perception. Learners work in pairs and sit on opposite sides of a "two-way" mirror. Both partners vary the amount light illuminating their faces. As they adjust the light, they begin to see themselves gradually assuming aspects of their partner's features, so that their image becomes a "composite" person. This activate guide includes instructions on how to build a two-way mirror.

Without certain species, ecosystems would crumble. In this amazing tour, explore keystone species around the world and how they help to maintain ecosystems around the world.

Students will observe/investigate the movement of water through the different stages of the water cycle and determine what drives this cycle. Students are asked to think about what precipitation is then watch a video about why the water cycle is important. They observe a simple version of the water cycle and take some notes. Students are asked what stages require solar radiation, which require water to give off heat, and which are driven by the force of gravity. The teacher does several different demonstrations while students fill in a sheet that has the students recording their observations of different processes in the water cycle and how energy is involved. Students build their understanding of the water cycle through the different models that are shown or experienced. The culminating activity has them create their own model of the water cycle from the viewpoint of a water molecule including the processes, the energy involved, and gravity.

Play with a bar magnet and coils to learn about Faraday's law. Move a bar magnet near one or two coils to make a light bulb glow. View the magnetic field lines. A meter shows the direction and magnitude of the current. View the magnetic field lines or use a meter to show the direction and magnitude of the current. You can also play with electromagnets, generators and transformers!

Investigate Faraday's law and how a changing magnetic flux can produce a flow of electricity! Best used as a demonstration and not a full lesson.

Light a light bulb by waving a magnet. This demonstration of Faraday's Law shows you how to reduce your power bill at the expense of your grocery bill.

Explore pressure in the atmosphere and underwater. Reshape a pipe to see how it changes fluid flow speed. Experiment with a leaky water tower to see how the height and water level determine the water trajectory.

The is a google sites learning hub all about force and motion. There are different activities that cover what force is, pushing and pulling, and simple machines. There is also a fun activity to learn about some famous scientist (some of whom contributed to the knowledge we have of force). Activities included use google earth, google forms, google slides, and other google tools. 

The goal of this lesson is to assist students to relate the forces acting upon particular objects and the “unseen” resolution of those forces. The video begins with a story line involving Adam, who helps his father in the garden by disposing of a garbage bag of leaves—the very act that involves resolution of forces. This lesson includes embedded video clips, animations, diagrams and inquiry-based experiments where students are required to work collaboratively and answer thought-provoking questions. The experiments will involve the study of the resolution of forces on objects placed on varying planes or on platforms of different angles, using materials that are easily found. Finally, students are required to discuss and apply what they have learned to determine whether it is easier to push or to pull a luggage bag with wheels. The lesson will take about 50 minutes to complete.

Students will conduct a number of investigations involving density and buoyancy to understand the forces applied to objects and the resulting interactions among them.

Explore the forces at work when you try to push a filing cabinet. Create an applied force and see the resulting friction force and total force acting on the cabinet. Charts show the forces, position, velocity, and acceleration vs. time. View a Free Body Diagram of all the forces (including gravitational and normal forces).
