5 Answer Keys Science Activities ACTIVITY 113 Where Is It? (Science Lesson 141) 1 Answers will vary. Sample answers include: above, below, beside, under, right, left. 2 Answers will vary. ACTIVITY 114 Rolling Balls (Science Lesson 143) Trial times will vary depending on how much force was used to push the ball or how straight the path of the ball was. 1 He should list the trial with the lowest time in seconds. 2 fastest speed (Tell him because it takes the least amount of time to cover the distance.) 3 Possible answers: pushed the ball harder or it rolled straighter ACTIVITY 115 Marbles on the Move (Optional) (Science Lesson 143) Predictions Possible answer: I predict the marble will roll ten meters after coming down the ramp. If I make the height of the ramp taller, the marble will roll farther across the floor. 1 Answers will vary. 2 The ramp height is increased as more books are added. 3 Your student should notice that the marble rolls farther as the ramp height is increased. ACTIVITY 116 Toy Tester (Science Lesson 145) Pushing Both ACTIVITY 117 Pushes and Pulls (Optional) (Science Lesson 145) 1 force 2 push 3 away 4 pull 5 gravity 6 size 7 smaller 8 friction 9 rub 10 The rough bottoms increase friction and keep you from slipping. ACTIVITY 118 Lift It Up (Science Lesson 146) 3 The book goes up. 4 no 5 It can make it easier for you to lift something. Simple Machines 1 pulley 2 lever 3 ramp ACTIVITY 119 Pulling 1, 3 2, 4 8, 6 5, 7, 9, 10, 11 What Blocks a Magnet? (Science Lesson 148) 1 Possible answer: I predict the magnet will attract the paper clip through water. 2 yes 3 Optional materials might be a sheet of paper, fabric, plastic, rubber, salt water. Macmillan/McGraw-Hill Comparing Magnets Number sentences will vary but should accurately reflect a greater than or less than relationship. ACTIVITY 120 Energy and Color (Science Lesson 150) 1 heat: fireplace 2 light: lamp 3 sound: earphones 4 electricity: wall or electrical socket Colors and Heat 2 Possible prediction: The plastic bottle covered in white paper will heat up more. 4 Possible answer: The bottle with black paper feels warmer. The balloon on it is blown up. 5 Dark colors absorb heat more. ACTIVITY 121 Glow Sticks and Heat (Science Lesson 151) Possible predictions: 1 The glow stick will grow brighter in the hot water. 2 The glow stick will be dimmer in the cold water. 12 Answers will vary for the temperatures on the observation chart, but student should notice that the glow stick is brighter in the hot water. What did you learn? 1 Accept any reasonable explanations. Your student should compare the two results. Explanation: In the hot water, the glow stick should glow brighter but will not last as long because the reaction is speeding up with the added heat energy. In the cold water, the glow stick should not glow as brightly but will last longer. (This is why the directions on the package often direct you to store the glow stick in the freezer to help slow down the reaction so it will last longer.) 2 Possible 77

6 Science Activities Answer Key answers are the sun, wind, heat from magma underground (geothermal), fossil fuels, water (hydroelectric), or nuclear energy. 3 with a thermometer ACTIVITY 122 Make Some Music (Science Lesson 153) 1 the glass with the least water 2 the glass with the most water 3 You could change the sound by adding more water or taking away water. ACTIVITY 126 Alternative Energy (Science Lesson 158) 1 pictures with an X: truck, ship, tractor, plane, cooking 2 pictures circled: skateboard, surfer 3 colored pictures: sailboat, truck, cooking, tractor, ship ACTIVITY 123 Let the Light Shine (Science Lesson 155) 1 Answers will vary. What did you learn? 1 2 Answers will vary. Activity 2: Stained Glass Window 5 Possible answer: The light changes color to the color of the plastic when it passes through the colored plastic wrap. 6 Possible answer: Light does not pass through the construction paper because it blocks the light. The light travels through the plastic wrap. ACTIVITY 124 Electricity (Science Lesson 156) 1 The vacuum cleaner uses electricity to clean the floors. 2 This egg beater does not use electricity. 3 The computer uses electricity. We use it to type and search the Internet. 4 The cell phone uses batteries to work. We use it to talk to people. Electricity at Home Electricity Sample answer: The mother and son are using an electric mixer to make dinner. Without Electricity Sample answer: Without electricity the family would have to stir the mixture by hand. They would have to use candles to see. 78
