1 T E A C H E R S N O T E S Focus: Students explore forces and the ways things move. Students will also learn which forces push or pull, what makes things stop, start, and change direction, how wheels and simple machines help us to move things, and how machines can be both helpful and harmful. Learning Goals: Students will have opportunities to learn how to correctly use the terms force, push, pull, direction, friction, gravity, axle, load, simple machine, pollute, slide, glide, twist, turn, roll that a force is a push or a pull that things move in many ways how gravity and friction can stop, start, slow down or speed up movement how wheels work to make moving easier how wheels and axles work how humans use simple machines to help them move from place to place how machines can be both helpful and hurtful Discussion Prompts: What are all the ways that things move? What forces make things move? What forces make things stop and start? How do wheels help us move things? How have wheels changed over time? How do machines help us move? What impact do machines have on our daily lives? How can we reduce the environmental harm that machines cause? Assessment Prompts: Do students demonstrate, in their discussions and answers to questions, understanding of the science vocabulary used in the cards for this unit? Are students able to carry out the skills of scientific inquiry, following activity safety procedure steps safely and accurately, making observations when appropriate? Assess students responses during discussions. - Do students understand that a force is a push or a pull? - Can students explain how forces make things move? - Can students explain the concepts of stop, start, slow down, push, pull, change direction? - Can students explain how wheels are an important simple machine in our daily lives? Can they explain how it works? - Do students understand how machines are used to move things and people? - Can students suggest ways to reduce the negative environmental effects of machines and how we can use machines wisely?

2 Focus: Students explore how things move and what forces make them move. Activity Description: By clicking on the blue plus icons, the pictures and text answer the Think question. Students then click on the orange icon to complete a timed activity to sort items into categories based on where things move. Students click the continue icon to drop labels onto the sorting chart from the previous screen. Learning Goal: Students learn that things move at different speeds for different reasons. Ask Students: How do different things move? Assessment: Are students able to give several of the different ways things move? Introduce students to the topic with the video of children playing hockey. Discuss the video and any comments or question students have. Activity Description: By clicking on the blue plus icons, the pictures and text answer the Think question. Students click on the orange icon to play a bowling game. Students must select a bowling ball and the appropriate force to knock down the pins. Learning Goal: Students learn about how force makes things move. Ask Students: How do things move when the force is changed? Assessment: Are students able to describe how different forces move things at different speeds? PCSP Interactive Science Teacher s Notes 2

3 Activity Description: In the new screen that appears, students drop labels (push or pull) onto objects to explore what force is used to move an object. Learning Goal: Students enhance their understanding of how the push and pull forces move objects. Ask Students: What force is needed to move different objects? Assessment: Are students able to explain whether an object needs a push or pull to move? PCSP Interactive Science Teacher s Notes 3

4 Focus: Students explore what makes things stop, start and change direction. Activity Description: In the screen that appears, students click on blue dots to learn about forces on a roller coaster. Students can click on the blue icon on the right to watch a roller coaster in action. Learning Goal: Students explore what forces are used on a roller coaster. Ask Students: How does the force change as the roller coaster moves? Assessment: Can students describe how a roller coaster uses force to move? Introduce students to the topic with the video that shows children looking at a map and compass, during a hike. Discuss the video and any comments or questions students may have. Activity Description: In the new screen that appears, the text and picture answer the Think question. Students click the orange icon to drag direction labels onto a compass diagram. Learning Goal: Students learn about the directions on a compass. Ask Students: What are the four main directions on a compass? Assessment: Can students draw and label a compass with the four directions? Activity Description: In the new screen that appears, the text and pictures answer the Think question. Students click the continue icon to get more information. Learning Goals: Students enhance their knowledge about how a maze works. Ask Students: How does a maze work? Why is it tricky to be in a maze? Assessment: Can students draw a maze and use directions to describe how to get out of their maze successfully? PCSP Interactive Science Teacher s Notes 4

5 Activity Description: In this screen, Up, Down, Under, Over, students drag and drop labels onto a picture of playground equipment. Learning Goal: Students will consolidate their understanding of directions. Ask Students: Do they understand what each direction means? Assessment: Can students explain and show you in their actions that they understand the meaning of each direction? PCSP Interactive Science Teacher s Notes 5

6 Focus: Students explore how wheels help us move things and what kind of machine a wheel and axle is. Introduce students to the topic with the video slide show of different machines that use wheels. Discuss the video and comments or questions students may have. Activity Description: Students click on the blue plus icons to learn more about how wheels are being used and answer the Think question. Students click on the orange icon to complete a timed matching game about wheels. Learning Goal: Students explore how wheels are used. Ask Students: What uses wheels to move? How many wheels are needed to make it work? Assessment: Can students describe/draw how some machines use wheels to work? Activity Description: Students click on the orange dots to answer the Think question. Students then click on the continue icon to learn about how wheels have changed over time. Students complete the last activity by clicking on the orange icon and dragging and dropping labels onto the vehicles in the picture. Learning Goal: Students discover how wheels have changed over time. Ask Students: How have wheels changed over time? Assessment: Are students able to describe/draw how wheels have changed over time? Can they explain the pros and cons of the use of each of these vehicles?
