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?

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
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
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.
