Lesson 5 Physical sciences FORCED TO MOVE Lesson plan Introduction: 1. As a class, watch the cartoon at . What happened to the apple when it was no longer attached to the tree? What happened to the apple after Newton threw it in the air? What happened to the two apples when Newton held them in his hands and then let them drop? Where did the objects land? Were the objects being pulled or pushed towards the Earth? What other examples were shown of things falling towards the ground? QP Development: 2. Divide the class into pairs and give each pair a copy of page 131. Students read each test in the table and draw the path they predict the beanbag will take when the test is conducted. Note: Ensure students use a lead pencil to record their predictions. QP 3. Give each pair a beanbag to conduct the tests on page 131. Students explore how objects move differently when they are dropped, pushed off a surface, pulled off a surface and thrown in the air. For each test, students observe the path the beanbag traveled and use a red pencil to record their result on the same image as their prediction. PC PA 4. Students compare their predictions to their results and record if their predictions were correct by placing a tick in the last column on page 131. PA 5. Students share their results with another pair and suggest reasons for any differences that occured, such as the amount of push given to each object. Students compare the general path taken by the object in each pair’s results. Prompt students by asking, Do both pairs’ results for test one show the beanbag moving straight down to the ground? Do both pairs’ results for test two show the beanbag moving across the table, then changing direction and moving down to the ground? PA E Differentiation: • Less capable students may be prompted by one question at a time, allowing them to concentrate on one set of results at a time. • More capable students may be encouraged to explain why they think the beanbag moved to the ground during each test and record these explanations on the back of page 131. 6. View the video investigation Defining gravity at . This video explains what gravity is and how Sir Isaac Newton discovered it in simple terms. Students compare the results of the video investigation to the their results. Did you come to the same conclusion? PA Reflection: 7. Divide the class into pairs and give each pair an iPad® or digital camera. Students create a video in a quiet location to answer the question What is gravity and how does it work on objects that are pushed or pulled in different directions? Students explain as much information as they can about gravity. If time allows, students may be encouraged to email their video to the teacher to show what they’ve learnt. If resources are limited, conduct this activity using an interview-style discussion. C © R.I.C. Publications Low resolution display copy 130 Science: A STEM APPROACH YEAR 2 978-1-925431-95-7 R.I.C.

Physical sciences FORCED TO MOVE The beanbag’s path Draw the path a beanbag will travel when each test is conducted. Use a lead pencil to record your predictions and a red pencil to record your results on the same image. Test Path travelled Correct? 1. Place the beanbag in your hand and hold your hand out straight in front of you. Drop the beanbag. 2. Place the beanbag on the table near the edge. Give the beanbag a push using a large amount of force. 3. Place the beanbag on the table near the edge. Give the beanbag a pull using a large amount of force. Remember to stay out of the beanbag's path! 4. Throw the beanbag above your head so that it lands on the table using a medium amount of force. Remember to throw your beanbag carefully so it doesn't hit anyone! Lesson 5 © R.I.C. Publications Low resolution display copy R.I.C.
