 Table of Contents Lesson Big Question 1. Pushes, Pulls, and Motion What is force? 2. A Force is a Push or a Pull What balanced and unbalanced forces? 3. Investigating Forces- Day 1 How do forces affect the motion of objects? Investigating Forces- Day 2 Part A- Forces and Motion Part B- Friction is a Force Part C- Predicting Motion Part D- Magnetism is a Force Unit Review and Assessment Lesson 1 The picture shows Death Valley National Park. It is the lowest place in North America. Large rocks move across the ground, without people moving them. What do you think could cause the rocks to move? 1. force 2. motion 1. force- a push or pull 2. motion- the process of an object changing position What are two pulls and pushes you might see on the playground? Lesson 2 Draw a picture of an object in MOTION. 1. balanced forces- a collection of forces acting on an object 2. unbalanced forces- a collection of forces acting on an object that result in a change in the object’s motion 3. gravity- a force that pulls objects towards Earth’s surface Discussion What are the pushes and pulls acting on objects in the following examples: » a ball being dropped to the ground » a book sitting on a table » a crayon being used to color something » the sailing stones in Death Valley » a tree branch that breaks suddenly Investigation Soccer Game Example–Click here Draw a picture of unbalanced forces. Remember if the object’s motion changes, it has unbalanced forces. Lesson 3 Day 1 Place an eraser on a flat surface and apply push and pull forces to the eraser. 1. Are the forces acting on the eraser balanced or unbalanced when the eraser was at rest (not moving) and when it was in motion? 2. Draw the direction of the forces with arrows. 1. predict 1. predict- to say something is expected to happen Thales Outcome 9 Cooperative Team Member Reflection Think about how you worked with your group today. List one star moment (something your group did well) and step moment (an area to work on tomorrow) Lesson 3 Day 2 Write two sentences using the word predict. Sentence 1: Use predict in a scientific way. Sentence 2: Use predict in a non-scientific way Discussion What direction did an object move when pushed? Did the object move in the same direction when it was pulled? What happened when two or more equal forces were applied in opposite directions? What different kinds of motion happened when multiple forces were applied in different directions? Answer the big question: How do forces affect the motion of objects?  Table of Contents Lesson Big Question 4. Investigating Friction Day 1 How does the force of friction affect motion? Investigating Friction Day 2 5. Friction is a Force What are the characteristics of the force called friction? Part A- Forces and Motion Part B- Friction is a Force Part C- Predicting Motion Part D- Magnetism is a Force Unit Review and Assessment Lesson 4 Day 1 Teacher Directions- Investigation Set Up Which slide do you think would be faster? Why? 1. friction 2. lubricant 1. friction- a force that occurs between the surfaces of two objects that are touching. 2. lubricant- a substance that reduces friction Teacher Directions Look back at today’s warm up. Using what you learned during the investigation, why would the slide with bumps be slower than the smooth slide? Lesson 4 Day 2 Today you will be working in a small group. What is one expectation for group work? Use your observations to write a sentence that describes the cause-and-effect relationship of friction. Use the phrase, “The _________ caused_________.” Lesson 5 1. Complete the activity with your teacher. 2. Answer this question: Could you warm your hands the same way if each hand were covered with a slippery lotion? Why or why not? 1. contact force 2. oppose 1. contact force- a push or pull between two objects that are touching each other 2. oppose- to work against ”Friction is not acting on this student because he is not moving.” Agree or Disagree? Teach a first grader about friction! Write down what you would say, and draw pictures to help them understand. *Remember, 1st graders have a smaller vocabulary than a third grader. You may need to explain key words!  Table of Contents Lesson Big Question 6. Predicting Patterns of Motion- Day 1 Can we predict the motion of an object that moves in Predicting Patterns of Motion- Day 2 regular patterns? Part A- Forces and Motion Part B- Friction is a Force Part C- Predicting Motion Part D- Magnetism is a Force Unit Review and Assessment Lesson 6 Day 1 Complete Lesson 5 check. Use your notes and student reader to help! Motion can form patterns! If a force pushes an object from one direction, the object will move in the opposite direction. If a force pulls something from one direction, the object will move in the same direction. On Earth, gravity pulls objects down toward the ground. Friction opposes motion. Making a pendulum Lesson 6 Day 2 Review the worksheet from the last lesson “Forces and Patterns”. Make a list of 3 ways the different patterns of motions you observerved. Example: back and forth 1. pattern 2. predict/prediction 1. pattern- something that keeps repeating 2. predict/prediction 1. What happens to objects that experience a push force? 2. What happens to objects that experience a pull force? 3. How does this provide evidence for patterns of motion?  Table of Contents Lesson Big Question 7.Investigating Magnets How do magnets interact with different materials and each other? 8. Magnetism is a Force What are the characteristics of the force called magnetism? 9. Solving Problems with Magnets- Day 1 What problems can be solved with magnets? Solving Problems with Magnets- Day 2 Unit Review and Assessment Lesson 7 The picture shows a clue about what you will be learning today. Make a prediction (guess) about today’s topic! Shhh! Don’t tell anyone! 1. attract 2. magnet 3. magnetism 4. repel 5. magnetic poles 1. attract-to pull something closer 2. magnet- a material that applies the force of magnetism 3. magnetism-a force that can push or pull 4. repel 5. magnetic poles  Have you seen or used a magnet? Do you know of or use magnets in your home or in the classroom? Have you ever wondered how a magnet works? Investigation Discussion Did any of the objects attract to the magnet? Which ones? Investigation Discussion- Patterns How were you able to predict (guess) which objects would be attracted to the magnet? Investigation Discussion- Cause and Effect Describe your observations about magnetism using “The ____________ caused __________.” For example “The magnet caused the paper clips to move toward it” Lesson 8 List three examples of friction. Explain the effects of friction in each case. Example: starting a campfire by rubbing two sticks together. 1. repel 1. repel- to push away from Complete the Lesson 8 Check. Use your notes and student reader to help! Write an acrostic poem to summarize the information you learned in Chapter 4. Example of a science acrostic poem Lesson 9 Day 1 Imagine living during a time without maps, satellites, or GPS. When explorers went out to sea or traveled the land, they had to rely on other ways to know whether they were heading north or south or east or west. What do you think they used to help them with directions? 1. problem 2. solution 1. problem- a need or want that requires a solution 2. solution- a plan or object that solves a problem Video– Click Here Create an advertisement for a magnet that solves a problem. Include: The problem and how the magnet solves it A persuasive slogan that will convince others to purchase it A colorful and eye-catching picture Examples of advertisements Lesson 9 Day 2 Define problem and solution in your own words. Outcome Reflection: What is one outcome you used today during the investigation?
