Air A Powerpoint presentation explaining the characteristics of air and how air exerts pressure.	All About Forces Module An excellent explanation of how gravity, friction, compression, stretching and magnetism are all forces. Learners complete a series of tasks as they understand the science.	Acceleration Learners perform a series of experiments and fill in a chart with the results to understand how mass, force and acceleration are related.	3 Puck Chuck Dubious link but good fun and very skilful.
All About Forces Module An excellent explanation of how gravity, friction, compression, stretching and magnetism are all forces. Learners complete a series of tasks as they understand the science.	Balancing Act A 'drag and drop' activity putting objects in a balancing pan so that they balance.	Air Pressure Video This activity needs to be loaded from the drop-down list to the right. The video clip is followed by a classroom experiment showing the topic.	About Forces Questions A series of questions which test learner's understanding of the science.
Cannonball into orbit Learners have to work out how much gunpowder is needed to put a cannonball into orbit. Air pressure, friction and gravity all feature.	Build a Roller Coaster An activity where learners build a rollercoaster to transport a ball across the screen.	Design Roller Coaster Run Learners choose five sections of track from the options given. Their design is then judged on safety and fun.	Forces and Motion Information about forces and motion followed by an 11 question quiz marked online about the information given.
Crash Test Dummies A visual explanation of how crash test dummies help with car safety.	Friction Module An excellent explanation of how friction is caused by two surfaces in contact with each other. Learners complete a series of tasks as they understand the science.	Forces and Movement An activity where learners push softly or hard to move a toy truck along a track. Tasks have to be completed including having a gradient on the track. A 5 question quiz test the understanding.	Forces Quiz A simple 10 question quiz marked online.
Forces 1 An animation showing the forces of thrust, air resistance and friction. Explains balanced and un-balanced forces.	Gravity An activity which involves estimating the effect gravity will have on a basketball and a weight.	Forces in Action A gravity and friction activity where learners release a toy truck down a ramp and record the distance it travels. Weights and parachutes are added to the truck and the process repeated.	Friction Questions A series of questions which test learner's understanding of the science.
Forces 2 A visual explanation of the forces of pushing, pulling, twisting, stretching, bending and sliding.	Gravity/Compression Middle An excellent explanation of how the force of gravity works and then compares gravity on the Earth and Moon. Learners complete a series of tasks as they understand the science.	Forces/Motion Application 4 sets of slides on 'Friction', 'Balanced and Un-Balanced Forces', 'Gravity, Stretching and Compression' and 'Magnetic Forces'. Each considers how these aspects of forces are used in the world.	Gravity and Friction Test An 8 question test marked online covering pushing, pulling, gravity, friction and air resistance.
Friction Module An excellent explanation of how friction is caused by two surfaces in contact with each other. Learners complete a series of tasks as they understand the science.	Lunar Lander You can get a good feel for gravity and inertia playing this game! Try to land on the moon, on the Earth and on Jupiter. The moon will be the easiest since the gravity is the weakest there... You won't get pulled down as fast.	Friction A friction activity where learners propel a toy car along a track and record the distance it travels. Different surfaces are added to the track and the process repeated.	Gravity Questions A series of questions which test learner's understanding of the science.
Galileo Drops the Ball A simple demonstration of the concept of gravity by dropping spheres and feathers inside and outside a vacuum.	Push and Pull Activity 1 has learners estimating how far a toy car would move. Activity 2 is a simple drag and drop information exercise and Activity 3 gives 5 examples where learners say whether it is a push or a pull force.	Friction Video This activity needs to be loaded from the drop-down list to the right. The video clip is followed by a classroom experiment showing the topic.	Omega Sector An activity in which learners have to dock a spaceship with a space station by controlling fight angle and power. The gravitational pull of planets have an affect.
Gravity/Compression Mdle An excellent explanation of how the force of gravity works and then compares gravity on the Earth and Moon. Learners complete a series of tasks as they understand the science.	Roller Coaster Builder As the title suggests this activity enables learners to build their own roller coaster whilst understanding forces.	Goldberger to Go Although a game this activity will test the more able in practical applications of forces. An excellent but addictive activity. Be warned!!!	Roller Coaster An excellent activity which combines design technology with science. The science part concerns forces, accelerator, friction and gravity. The technology part is about the design of the perfect roller coaster.
Ocean Tides Animation A simple animation showing how the gravitational pull of the moon creates tides.	Roller Coaster Design An excellent activity which enables learners to design a roller coaster. This is not as easy as it seems but an excellent way for learners to understand the physics.	Parkworld Plot A game which incorporates the 'Forces Module'. Learners complete a series of tasks to find the unsafe ride in the amusement park.	Un/Balanced Forces Quest A series of questions which test learner's understanding of the science.
Propulsion An excellent animated site which explains a number of aspects of propulsion in simple and easy to understand steps. It covers propellers, sails, hot air and jet propulsion. As it is a simple video clip it can be repeated a number of times.	Un/Balanced Forces An excellent explanation of how the force of gravity works when balanced by an equal force in the opposite direction. Learners complete a series of tasks as they understand the science.	Pushes and Pulls An activity where learners push softly/hard or push softly/hard to move a toy horse along a track. A number of tasks have to be completed including placing items on the track. A 5 question quiz tests the understanding.
Roller Coaster A simulation of a roller coaster in which learners can change the shape and height of the ride and be shown aspects of friction in action.		Rail Slide An activity of energy, elevation and power within a skateboard park. Learners create the right conditions for the jump.
Stop the Truck A site which allows learners to compare the stopping distances of vehicles in dry, wet and icy weather conditions. Good for demonstration of friction or more perhaps little friction.
