This is the eighth lesson in a unit of work on forces which could be adapted for use at KS3 or GCSE. The lesson investigates what balanced and unbalanced forces are and how they effect object motion and acceleration. During this lessons pupils will: Recap weight calculations from previous lesson. Recap free body diagrams from previous lessons to prepare for using them in this lesson. Recap Newtons three laws of motion highlighting the second law. Consider and discuss the forces acting on a stationary object. Consider and discuss forces acting on an object at constant speed. Define balanced forces. Consider and discuss forces acting on an object that is accelerating. Define unbalanced forces. Learn how to calculate resultant forces Calculate resultant force for two different situations. Complete a fill in the gaps consolidation task. A bundle of all 8 lessons in this unit can be found here.

This is the second lesson in a unit of work on motion and pressure. The lesson is aimed towards KS3 but could be adapted to other levels. The main focus of the lesson is to introduce pupils to distance-time graphs, how to interpret them to describe motion and how to use them to calculate speed. During this lesson, pupils will: Use previous knowledge to estimate the speed of light using the speed equation. Estimate the speed of a person traveling in different ways and use this to calculate how long it would take to move 20m using the speed equation. Identify the key features of a distance-time graph. Use a distance-time graph to compare and calculate the speed of three different objects. Complete a matching activity to describe the motion of a person walking to catch a train from a distance-time graph. Use a distance time graph to calculate the speed of this person and analyze their motion. Sketch a distance-time graph from a set of descriptions of someones motion. Describe what a curved line on a distance-time graph shows. Complete some short consolidation activities.

This is the fourth lesson in a unit of work on motion and pressure. The lesson is aimed towards KS3 but could be adapted for other levels. The main focus of the lesson is to introduce pupils to liquid pressure, its causes and effects. Pupils will also look at the effect of depth on liquid pressure and use associated forces to explain floating and sinking. During this lesson pupils will: Use an image of a blobfish at the surface to infer information about the effect of water pressure. Recap work from last lesson on pressure in gases and link to pressure in liquids. Recap the particle model of a liquid, discuss its motion and how this causes pressure on an object submerged in it. Consider the changes in pressure on a fish as it swims deeper. Investigate and graph the relationship between depth and pressure experienced. Use knowledge of forces to explain why some objects float while others sink. Complete some short consolidation tasks to check understanding.

This is the fifth lesson in a unit of work on sound. The lesson was aimed at KS3 but could be adapted for other levels. The main focus of the lesson is to investigate why sounds echo, sound reflections and their practical uses. For a bundle of all five lessons in this unit, click here. During this lesson pupils will: Complete questions to recap knowledge from previous lessons in unit. Watch and analyze a talk by Daniel Kish who uses echolocation to “see” the world. Discuss own knowledge about echoes. Recap what happens to waves when they collide with a barrier. Learn what causes an echo and complete a fill in the gap activity to describe it . Investigate the problems for reverberation in cinemas and suggest solutions. Recap the speed equation and how to rearrange it. Investigate SONAR and complete practice calculation questions to work out distance and time. Investigate ultrasound scanning. Complete true or false consolidation task.

This is the first lesson in a unit of work on motion and pressure. The lesson is aimed towards KS3 but could be adapted for other levels. The main focus of the lesson is to introduce pupils to the concept of speed, the speed equation and to conduct some short practicals on measuring speed. During this lesson pupils will: Discuss who is faster, Usain Bolt or a cheetah. Complete questions to assess their own knowledge about speed. Consider the speed equation and use a formula triangle to rearranging it to find distance and time. Complete calculation questions using the speed equation to find speed, distance and time. Use a video to measure Usain Bolts speed during his world record race and compare it to a cheetah to answer question from start of lesson. Complete a short practical to measure the speed of a rolling ball including calculating mean speed, measuring distance and measuring time. Complete a short practical to measure the speed of a person walking. Please visit my shop for more lessons in this unit and other science, history and geography resources.
