GRADE3 SCIENCE

McGraw Hill Unit 1: Forces Around Us

Motion & Forces

Electric & Magnetic Forces Lesson 1: Electricity Lesson 2: Magnets

Lesson 1: Motion Lesson 2: Forces Can Change Motion

the direction of a force, or how distance between objects affects the strength of a force. Electrical charges and magnetic felds will be taught in Grades 6 through 8. (PS2.B) Standard 3.3.5: Design a solution to a problem in which a device functions by using scientifc ideas about magnets. Defne the problem, identify criteria and constraints, develop possible solutions using models, analyze data from testing solutions, and propose modifcations for optimizing a solution. Examples could include a latch or lock used to keep a door shut or a device to keep two moving objects from touching each other. (PS2.B, ETS1.A, ETS1.B, ETS1.C) CONCEPTS SKILLS ● Balanced & Unbalanced Forces

● Plan and carry out investigations ● Provide evidence ● Analyze and interpret data ● Construct explanations ● Design a solution

● Motion of Objects ● Patterns in Motion ● Gravitational Force ● Electric and magnetic interactions

LEARNING PROGRESSIONS 1. Observe and measure an object’s motion to recognize that patterns can be used to predict future motion. 2. Observe the way objects move using a marble. 3. Read about how objects move. 4. Look at images to show different types of motion.

5. When a force is applied to an object its motion changes. 6. Investigate the relationship between force and motion. 7. Read about forces on objects. 8. Determine what forces move objects. 9. Ask questions that can be investigated to explore electricity.

10. Observe how a charged balloon affects other objects. 11.Read about electrical energy and static electricity. 12.Explain how magnetic forces can be utilized. 13.Experiment to fnd out which objects are pulled by magnets. 14.Read about magnets and magnetic felds. 15.Determine which objects magnetic forces can pass through. 16.Make an electromagnet. 17.Learn how magnets can be used to solve problems. END OF UNIT COMPETENCY WITH LANGUAGE FEATURES & FUNCTIONS I can carry out an investigation to determine the relationships of electric or magnetic interactions
