4 Science GLCEs Incorporated in Pushes and Pulls Please see the complete Science GLCEs at Below are some areas of the GLCEs for your reference that particularly pertain to this unit. Please reference the document at the link above for all Kindergarten Science GLCEs. Physical Science: Force and Motion Prior to entering kindergarten, many students have developed an understanding of the motion of objects. For example, the young learner has discovered that solid objects cannot move through each other, changes in motion and position of objects are the result of a force outside them, and that objects tend to endure over space and time. They learn even though the ball has rolled out of sight, it still exists behind the wall, under the couch, or behind someone s back. They can also make inferences about reasonable causes of motion of inanimate objects. Pre-kindergarteners have their own concept of force that they use to explain what happens in the motion of objects. They think of forces as active pushes and pulls that are needed to explain an object s motion. The kindergarten content expectations for physical science are meant to build on and use the early learners ability to correctly sense some of the behaviors of simple mechanical objects and the motion of objects. The central idea is for the young learner to be able to attach appropriate language that describes motion, compares motion, and begin to develop an understanding of forces and their relationship to changes in motion. Finally the students are introduced to the concept that objects fall toward the Earth and that the force that pulls objects toward Earth affects the motion of all objects. PHYSICAL SCIENCE: Force and Motion K-7 Standard P.FM: Develop an understanding that the position and/or motion of an object is relative to a point of reference. Understand forces affect the motion and speed of an object and that the net force on an object is the total of all of the forces acting on it. Understand the Earth pulls down on objects with a force called gravity. Develop an understanding that some forces are in direct contact with objects, while other forces are not in direct contact with objects. Page 3 2

5 P.FM.E.1 Position- A position of an object can be described by locating the object relative to other objects or a background. * P.FM Describe the position of an object (for example: above, below, in front of, behind, on) in relation to other objects around it. * P.FM Describe the direction of a moving object (for example: away from or closer to) from different observers views. * P.FM.E.2 Gravity- Earth pulls down on all objects with a force called gravity. With very few exceptions, objects fall to the ground no matter where the object is on the Earth. P.FM Observe how objects fall toward the earth. P.FM.E.3 Force- A force is either a push or a pull. The motion of objects can be changed by forces. The size of the change is related to the size of the force. The change is also related to the weight (mass) of the object on which the force is being exerted. When an object does not move in response to a force, it is because another force is being applied by the environment. P.FM Demonstrate pushes and pulls on objects that can move. * P.FM Observe that objects initially at rest will move in the direction of the push or pull. P.FM Observe how pushes and pulls can change the speed or direction of moving objects. P.FM Observe how shape (for example: cone, cylinder, sphere) and mass of an object can affect motion. * * Revised expectations marked by an asterisk. Page 4 3

7 Overview of Lessons Lesson 1: Ways That Things Move Students brainstorm words for how things move Homework: students bring 1 toy with wheels to school for scientific experiments for the next 2 lessons Lesson 2: Pushes and Pulls Experiment with pushes and pulls on their wheeled toy Game: students, in pairs, push or pull their toy; partner needs to identify whether it was a push or pull Lesson 3: Position and Gravity Simon Says position game with your toy Introduce gravity concept and test it out on a slope with their toy (no pushes or pulls involved) last time they will need their toy with wheels Lesson 4: Speeding Up, Adding Weight Wooden cars adding a push or pull when moving Adding weights to wooden cars Lesson 5: Shapes in Motion Geometric shapes sorted by ability to roll Sit in group circle and test shapes to roll across floor Draw which shape rolled best in student journals Lesson 6: Sorting Motion Words Cut apart movement words from lesson 1 to sort into categories: direction, speed, position Lesson 7: What Would Happen If Game Drop, push, pull, etc. and students have to guess what will happen before you do the action you described Encourage scientific language when describing what will happen Page 6 5

8 Lesson 1: Ways that Things Move Materials List Chart paper and marker Lesson Overview: 1. Ask your students, What are some words for how things move? Students may think of fast, slow, rolling, falling, sliding, bouncing, etc. Write these words on a Ways That Things Move chart on chart paper. 2. Tell students their homework is to bring a toy that moves with wheels to school tomorrow. Note: Vocabulary listed with each lesson is highly recommended to use throughout the lessons. Vocabulary words are taken from the GLCE Companion Document. Suggested Vocabulary: None yet, take student suggestions only during this lesson. Page 7 6

9 Lesson 2: Pushes and Pulls Materials List: Student toy from home (extras from your collection or another classroom in your building) Lesson Overview: 1. Pushes and Pulls Students bring in toys that have wheels to work on their pushes and pulls, not throwing! Hands have to stay on the item so it does not fly away from them. You may have to split this activity into 2 days. 2. Experimentation Students will first play with their wheeled toy on a level area of floor in the classroom. Ask them to find a personal space to explore where they cannot reach any of their friends. Allow them this time so they can then follow directions of what to do with their toy next. 3. Tell students, Push the toy away from you. Then tell them, Pull your toy towards you. Ask students, What made your toy move? It is their hand giving it a push or a pull, but the hand has to do this kind of action to make it move. You can do this like Simon Says to make it into a game and give students practice. Students need to know they are practicing pushes and pulls, both towards them and away from them. Use these terms to introduce directionality as well. Practice pushing to the right or pulling to the left. 4. Have students work in pairs and either push or pull their toy. The other student has to identify whether they are doing a push or a pull. Suggested Vocabulary: Push Pull Towards Away from Right Left Page 8 7

Vocabulary: Speed Heavier Fast, Faster Lighter Slow, Slower Harder Weight Easier Page 10 Page 10 9

12 Lesson 5: Shapes in Motion Materials List: Geometric shapes Lesson Overview: 1. Predicting how shapes will roll Geometric shapes will be used to test how pushes and pulls work on various shapes. Sit in whole group with your class in a circle. Tell students to think about which shapes they think will be easiest to roll across the circle. Once students have had time to think, ask individuals to sort the shapes into rolls well or doesn t roll well piles, one student at a time coming up to choose an object and put it in one of the piles. Encourage students that many scientists do not agree before testing something, but they don t argue about it they do scientific testing to find out what is true. 2. Rolling shapes Roll each object across the circle to a student, one at a time. Discuss if they were right does it roll well or is it tricky to roll? Some shapes, like cubes, don t roll well because you have to push so much harder, or use more force, to get them to move. Stress that you re trying to make them all equal by pushing the same amount each time. Note: Make sure to discuss why some objects rolled faster or more easily than others. What is it about their shape that made it easier to roll? Vocabulary: Push Speed Shape Size Faster Slower Smooth Edges Points Page 11 10

13 Lesson 6: Sorting Motion Words Materials List Chart paper words from lesson 1, cut apart New chart paper and marker Tape or glue Lesson Overview: 1. Prep: Take chart paper words for how objects move (lesson 1) and cut them apart. 2. Have students help you sort the words into 3 categories: direction, speed, and position. Write these categories on the chart paper and tape words onto the category they belong in. Students may have new words they want to add after all the experimenting they have done. Let students decide which category these new words belong in and just write them on the chart. Below are some examples students may come up with: 1. Direction: right, left 2. Speed: fast, slow 3. Position: away, close, on, under, in front of, behind Page 12 11

14 Lesson 7: What Would Happen If Game Materials List Various objects chosen from around the room Lesson Overview: 1. Take an object from the room and either hold it in the air to drop, or put your hand on it as if to push it on the floor, or put your hand on it as if to pull it towards you, etc. Act as if you will do the action (but don t do it yet!) and describe what you will do by asking students, What will happen if I. 2. Call on individuals to tell you what will happen, using their new scientific words on pushes and pulls. Then have students come up and take a turn, using their scientific words. They may call on students to guess what will happen. Students can play this in small groups as well. Make sure they refer to your poster from lesson 6 for scientific words. 3. Example: Jerry puts his hand on the edge of the book and says, What will happen if I push the book away from me? It may help students if you model this quite a bit so they understand the formula.
