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. ### 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. ### Classroom Antarctica: breaking the ice

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 ... ### Series and Parallel Circuits

Students use this resource consisting of three slides with diagrams, written explanation and voice-over to understand how to the arrangement of bulbs in series and parallel circuits and understand the differences between them. There is a two-question quiz and a summary slide. ### Gravity and the Solar System

Students use this resource consisting of seven slides with diagrams, written explanation and voice-over to understand how the movement of planets around the sun is related to gravitational forces. There is a two-question quiz and a summary slide. ### Pivots and Levers

Students use this resource consisting of seven slides with diagrams, written explanation and voice-over to understand that forces can cause objects to turn about a pivot and that the turning effect of a lever depends on the force and its distance from the pivot. There is a two-question quiz and a summary slide. ### 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. ### 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. ### Factors Affecting Thinking Distance

Students use this resource consisting of nine slides with diagrams, written explanation and voice-over to understand that the stopping distance of a car depends on the alertness of the driver as well as its speed and frictional forces. There is a two-question quiz and a summary slide. ### 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. ### 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. ### Balanced Forces

Students use this resource consisting of five slides with diagrams, written explanation and voice-over to understand that balanced forces produce no change in the movement of an object. There is a two-question quiz and a summary slide. ### Magnetic Fields

Students use this resource consisting of ten slides with diagrams, written explanation and voice-over to understand that a magnetic field is a region of space where magnetic materials experience forces and learn that magnetic field line patterns show the relative strength of magnetic fields. There is a two-question quiz ... ### 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. ### Useful Friction

Students use this resource consisting of six slides with diagrams, written explanation and voice-over to understand how friction is needed in movement and braking. The fact that friction produces heat and causes wear is also mentioned. There is a two-question quiz and a summary slide. ### Satellites

Students use this resource consisting of eight slides with diagrams, written explanation and voice-over to understand that the moon is a natural satellite of the Earth and how satellites stay in orbit around the Earth. 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. ### 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.
