In this learning sequence students investigate the concept of force, simply described as a push or a pull. They find out how forces can change the shape or movement of an object and explore deformation: breaking, bending and how different materials react under different forces. Students plan and conduct a simple experiment ... ### Energy skate park

This is an interactive resource about the potential and kinetic energy changes as a skater rolls around a skate park. Students learn about conservation of energy with a skater, they can build tracks, ramps and jumps for the skater and view the kinetic energy, potential energy and friction as he moves. Students can also ... ### Balloon car challenge

In this practical activity, students design and build a balloon-powered car and race it to better understand the ideas related to rocket propulsion. The resource includes a step-by-step teacher guide and student worksheets. ### How the Rubber Meets the Road

Lesson focuses on how engineers design tyre treads to increase safety and reliability. Students are presented with the challenge of designing a new tyre tread that will be safe when driving in rainy conditions. Student teams will design and construct a sample tread out of clay, then test and evaluate the effectiveness of ... ### Kites

In this practical activity, students will learn about types of kites, some kite history and how kites fly before making and flying a kite themselves. The activity includes a teacher guide and student worksheet. ### Clockwise and Anticlockwise Moments

Students use this resource consisting of five slides with diagrams, written explanation and voice-over to understand that a moment is a turning force, which can be clockwise or anticlockwise. There is a two-question quiz and a summary slide. ### Plotting a Magnetic Field

Students use this resource consisting of seven slides with diagrams, written explanation and voice-over to understand how to plot the magnetic field around a bar magnet using a plotting compass. There is a two-question quiz and a summary slide. ### Unbalanced Forces

Students use this resource consisting of eight slides with diagrams, written explanation and voice-over to understand that unbalanced forces change the speed or direction of movement of objects and that balanced forces produce no change in the movement of an object. There is a two-question quiz and a summary slide. ### experiMENTALS: Bouncing balls

This resource contains a materials and instruction list and brief explanation for students to observe what happens when two different sized balls are dropped independently or in vertical contact. The simple explanation relates to transfer of energy. ### Sites2See – Nobel Prize physics

This page features the site nobelprize.org with information on the 2007 Nobel Prize in Physics, awarded for the discovery of Giant Magnetoresistance (GMR). Applications of this phenomenon have revolutionised techniques for retrieving data from hard disks and are considered the first real applications of nanotechnology. ... ### Circuit Diagrams

Students use this resource consisting of three slides with diagrams, written explanation and voice-over to understand how to draw simple circuits and the symbols used to represent them. There is a two-question quiz and a summary slide. ### Factors that Affect Braking Distance

Students use this resource consisting of ten slides with diagrams, written explanation and voice-over to understand that the braking distance of a car depends on its speed and other factors which affect the frictional forces needed to stop the car. There is a two-question quiz and a summary slide. ### Uses of Satellites

Students use this resource consisting of five slides with diagrams, written explanation and voice-over to understand some uses of artificial satellites including geostationary satellites. Uses identified include telecommunications, weather forecasting and spying. There is a two-question quiz and a summary slide. ### Stopping Distances

Students use this resource consisting of six slides with diagrams, written explanation and voice-over to understand how to calculate the total stopping distance of a car. There is a two-question quiz and a summary slide. This resource should be used before the resource 'Factors Affecting Thinking Distance'. ### Electric Current

Students use this resource consisting of four slides with diagrams, written explanation and voice-over to understand that current is the flow of electricity around a circuit and that the greater the resistance of the circuit, the less current flows. There is a two-question quiz and a summary slide. ### Magnetism and Electric Current

Students use this resource consisting of nine slides with diagrams, written explanation and voice-over to understand that wires carrying an electric current produce a magnetic field and that a current in a coil produces a magnetic field pattern similar to a bar magnet. There is a two-question quiz and a summary slide. ### Calculating Moments

Students use this resource consisting of seven slides with diagrams, written explanation and voice-over to understand the principle of moments and its application to situations involving one pivot. There is a two-question quiz and a summary slide. ### Gravity

Students use this resource consisting of four slides with diagrams, written explanation and voice-over to understand that gravity is a force of attraction which acts on Earth towards the centre of the planet, and that the size of the force of gravity depends on the mass of each object and the distance between them. There ... ### Fuses and Circuit Breakers

Students use this resource consisting of five slides with diagrams, written explanation and voice-over to understand how a fuse protects a circuit and learn some uses of resettable circuit breakers. There is a two-question quiz and a summary slide. ### What Forces Do

Students use this resource consisting of six slides with diagrams, written explanation and voice-over to introduce forces, indicate what they can do and how to measure them. There is a two-question quiz and a summary slide.
