Topic 6: Forces and Changes in Motion Benchmarks
SC.5.P.13.1 Identify familiar forces that cause objects to move, such as pushes or pulls, including gravity acting on falling objects. SC.5.P.13.2 Investigate and describe that the greater the force applied to it, the greater the change in motion of a given object. SC.5.P.13.3 Investigate and describe that the more mass an object has, the less effect a given force will have on the object's motion. SC.5.P.13.4 Investigate and explain that when a force is applied to an object but it does not move, it is because another opposing force is being applied by something in the environment so that the forces are balanced. SC.5.N.2.1 Recognize and explain that science is grounded in empirical observations that are testable; explanation must always be linked with evidence. LACC.5.SL.1.1 Engage effectively in a range of collaborative discussions (one-on-one, in groups, and teacher-led) with diverse partners on grade 5 topics and texts, building on others’ ideas and expressing their own clearly.

What is MOTION? Always a change in the position of an object.
Sometimes it may involve a change in direction, too. Engage: Discuss the motion in the clip art. Demo motion with real objects and students. Demonstrate with the hyperlink video: change in direction,. Department of Mathematics and Science

What changes motion? Motion of an object changes when a force acts upon the object. An object remains in motion, or at rest, unless a force acts on it. Explore/Explain: Click on first hyperlink to do exploration on Brain POP. Discuss answers. Click on second hyperlink force and play Study Jams . Discuss. Object in motion

Forces are a push or a pull.
What are Forces? Forces are a push or a pull. What happens when you hold up a book and drop it? What happens when you drop two books with different masses? Will they land at the same time or different times? Does this work every time with any two objects? What happens if you drop a book and a piece of paper at the same time? What if you crumple up the piece of paper? Now let’s visit the astronauts on the moon trying this out: Hammer vs Feather - Physics on the Moon Why does this happen? Now let’s look at a virtual experiment Galileo Drops the Ball What did Galileo learn? Galileo found any two objects will land at the same time. Earth’s gravity will pull harder on the object with the greater mass and the one with the smaller mass will have less force of gravity acting on it. What force can affect the pull of gravity? Air resistance or friction How does the force of friction impact an object’s motion? Friction works against gravity and slows down moving objects. Explain, extend, evaluate: Define force in your journal. Ask the questions one at a time and make predictions. Then have student volunteers drop the objects. Discuss observations. ( Note all objects should fall at the same time unless another force such as air resistance - friction works against the pull of gravity.) This will become evident to the students as you work through the demonstrations and the utube Nasa video and the virtual Galileo virtual lab.

Claim Evidence Reasoning (CER)
Assignment Part 1 Find force and motion investigation notes in your journal. Watch the Discovery video: Friction Do the Discovery Exploration: Changing the Speed of Motion. Last read the articles: Zamboni and Now That’s Fast. Be prepared to use evidence from what you investigated, read, heard and saw to support your answer to one of the following questions: 1. How does the force of friction change the motion of an object? 2. How do different forces cause objects to change speed? Explore, Explain, Evaluate Note: This CER is taken from the Force and Motion CER Conclusion Writing Power Point – Instructional Resources Grade 5 Quarter 1 Division of Academics - Department of Science

Claim Evidence Reasoning (CER)
Assignment Part 2: Complete the following in your notebook: My Question: (List question chosen.) Sample: 1. How does the force of friction change the motion of an object? Evidence: (Record all the evidence you gathered from investigations, readings, and videos.) Claim: (The answer to the question chosen.) Reasoning: (Use the evidence to help explain why you think the answer is correct.) Explain, Evaluate

What are Magnets? Let’s Explore! (SC.4.P.8.4)
Write down your observations as you explore. What happens if you put together two magnets? Turn one of the magnets around and do step 1 again. What happened? Was it the same? Experiment with different magnets and a bag of objects. Click to open Engage with a quick activity. Ask the question and open the hyperlink Magnets. Discuss. Give each group a pair of magnets. Click on the clip of the two sets of magnets with opposite poles matched to view a Discovery Ed. video clip on the concept. P-SELL St. Book Magnetic Forces pp. 79 – 82. Give each group a small bag of objects (magnetic and nonmagnetic) to explore with. If available, give each group of clear baggy with iron filings. Remind them for safety do not open the bag. Discuss their observations. P-SELL Student Book Magnetic Forces p. 79
15
What is Magnetism? Magnetism is the force of attraction or repulsion of a magnetic material due to the arrangement of its atoms. Explain: Ask essential question again. Listen to students’ ideas and explain. What are some everyday uses of magnets?
16
What do you know about the force of Magnetism?
Magnetism is a force. Metals stick to magnets. Magnets have different strengths. Magnets have two poles: north and south. Like poles repel. Opposite poles attract. The force of magnetism can travel through some objects. Explain/Evaluate Students share reflections: What do you know about magnetism now?

FCAT Review 1. Jordan makes the following list of choices for the science fair. Which choice would be scientifically testable? What do 5th graders think of playing tug of war? Which type of stone is the best looking in my rock collection? Does a ball roll farther on grassy PE field or on a asphalt basketball court? Is Mrs. Jones a nicer teacher than Mr. Mathews?

FCAT Review 2. Ricardo is conducting an experiment to see how far a rubber ball will roll when he releases it at the top of an inclined plane. Why does the ball speed up as it travels down the inclined plane? The force of gravity pulls the ball down the inclined plane. The force of friction is reduced because the ball is rubber. The ball has less magnetic attraction to the plane as it travels. The ball has a greater mass as it travels faster. Evaluate

FCAT Review 4. Tiffany is helping her parents to unpack some boxes. She lifts a full box with a mass of 15 kilograms. She empties out about half of the items from the box and lifts it again. Which is true regarding the force she applies after unloading the box? She has to apply a different type of force after changing the mass. She has to apply more force to lift the box because the mass is greater. She has to apply less force to lift the box because the mass has decreased. She has to apply the same amount of force to the box to overcome gravity. Evaluate
