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. ### 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. ### 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 ... ### 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 ... ### 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 ... ### The physics of a slinky drop

Imagine holding a slinky by the top end, with the bottom end dangling in mid-air. What do you think would happen when you let it go? Explore the physics of two equal and opposing forces working on an object in this awesome experiment! ### Sun's energy

What is the relationship between mass and energy? Dr Derek Muller uses the sun as an example to explain Einstein's famous formula, E=mc2. ### Effects of g-force on the human body

Peter Rowsthorn visits the Australian International Air Show to answer the question, 'What effect does g-force have on the human body?' Join Pete in the cockpit of a light plane for some aerobatics with pilot David Pilkington. G-force expert Dr David Newman explains the science as Pete endures up to 6 g in the aircraft. ### Can photons and atoms generate laser?

Electrons around atoms can absorb and emit photons of particular colours of light – see three different atomic models explain what's going on. ### Coal and its uses

Find out where we get the coal that powers our homes and industries. This is a PowerPoint presentation outlining how coal is formed, mined, processed and used. All slides contain images or maps. Teachers' notes are included. ### experiMENTALS: Straw propeller

This resource contains a materials and instruction list and brief explanation for students about the process of creating a propeller using two bendy straws and a pair of scissors. A simple demonstration of one of Newton's Laws. ### Forces

Students use this resource consisting of seven slides with diagrams, written explanation and voice-over to understand what forces are and what they can do. There is a two-question quiz and a summary slide. ### 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. ### 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. ### 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'. ### 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. ### 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. ### 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. ### 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.
