Down the ramp! Forces ~ Activity 2 Objective • observe and investigate the movement of objects such as toys on various materials and surfaces Working scientifically • Questioning • Observing • Predicting • Investigating and experimenting • Estimating and measuring • Analysing (sorting and classifying) • Recording and communicating Designing and making • Exploring Background information Objects at rest tend to stay at rest unless a force (push, pull) starts them moving on a level surface. They tend to keep moving in a straight line unless the force is at an angle. How well objects roll down a ramp depends on the shape and mass of the object and the texture of the object and/or the ramp. Before the lesson Materials needed • Ramp – strong cardboard or strong board, wooden blocks or books to prop ramp. • Variety of objects to test for rolling/sliding—tennis balls, ping-pong balls, erasers, toy cars, marbles, paperclips, plastic counters, modelling clay (form into strips and balls), different-shaped blocks, pencils, cotton reels, plastic cups, stones, empty matchboxes, ice cubes, feathers, straws, leaves, buttons, rice, grains etc. Preparation • Divide class into small groups with materials for the ramp and a selection of objects to test. Ensure those objects on the copymaster are included. The lesson Stimulus • Present pupils with two toy cars – one with wheels that turn and the other with fixed wheels. Ask volunteers to get the cars to move on a level surface. How much push or pull was needed? Did they roll, slide etc.? Predict what would happen on a ramp and then test. What to do • Discuss the results of the stimulus. • In groups, test a range of objects to see if they roll or slide down a ramp. (Construct as outlined in ‘Materials needed’ section.) • Repeat with a steeper ramp. • Discuss the following: Did the objects roll or slide further? Did some roll or slide at this height and not the previous height? What objects rolled or slid best? Were they rough, smooth, rounded, heavy, light etc.? After the lesson Answers 1.–3. Teacher check 4. The higher, steeper ramp will make the marble roll further. Viewing Sample Additional activities • Try different surfaces on the ramp such as carpet, plastic, sandpaper or water. How does each affect the rolling and sliding of objects? • Change the length of the ramp and see how this affects the rolling and sliding of objects. Display ideas • Pupils can draw or paste pictures on charts labelled ‘Things that Roll’, ‘Things that Slide’ and ‘Things that Stay Still’. 74 <strong>PR</strong>IMARY SCIENCE ~ Prim-Ed Publishing ~ www.prim-ed.com
Forces ~ Activity 2 Down the ramp! Test each object below to see if it will roll or slide down a ramp. Make a guess before you start. Add two more of your own. Viewing Sample (a) Which object rolled the fastest? (b) Which object slid the fastest? Choose an object that did not roll or slide. Explain why. Circle which ramp would make a marble roll further. www.prim-ed.com ~ <strong>PR</strong>IMARY SCIENCE ~ Prim-Ed Publishing 75
