Transcript

  • 1. SIMPLE MACHINES LAB Pulley
    • Materials: pencil, Simple Machines WS, Science Notebook, blinds
    • Procedure
    • Use the cords to release the blinds.
    • Now pull up the blinds using the pulley.
    • Sketch and explain the forces acting on the string/blinds.
    • QUESTIONS:
    • How can a pulley make lifting an object easier?
    • What does it do?
  • 2. SIMPLE MACHINES LAB Inclined Plane
    • QUESTIONS:
    • How can an inclined plane make it easier to lift up an object?
    • How can the momentum of each ball be described? (Use the words mass & velocity)
    • Materials: pencil, Simple Machines WS, Science Notebook, 2 small balls (different sizes), ramp (two boards)
    • Procedure
    • Roll the ball down the ramp.
    • Roll the ball up the ramp.
    • Use a different ball. Repeat.
    • Sketch and explain the forces acting on the ball.
  • 3. SIMPLE MACHINES LAB Screw
    • Materials: pencil, Simple Machines WS, Science Notebook, screws, monkey wrench, screw drivers
    • Procedure
    • Find the screw on the monkey wrench. Sketch & label.
    • Screw each of the screws into the wood. (Righty tighty, lefty loosey)
    • QUESTIONS:
    • Which screw was easiest? Hardest?
    • Look at the screws. How are they different? How could this explain it?
  • 4. SIMPLE MACHINES LAB Wedge Task 1
    • Materials: pencil, Simple Machines WS, Science Notebook, wedge, clay, nail, pin, cloth
    • Procedure
    • TASK 1:
    • Stick the needle in the cloth.
    • Pull it out. Use the other end. Answer the question for task 1
    • QUESTIONS:
    • TASK 1
    • Does using the eye-end work? Which works better? Why?
  • 5. SIMPLE MACHINES LAB Wedge Task 2
    • Materials: pencil, Simple Machines WS, Science Notebook, wedge, clay, nail, pin, cloth
    • Procedure
    • TASK 2:
    • Press the wedge flat side into the clay.
    • Press the wedge point side into the clay. Answer the questions for Task 2.
    • Roll the ball of clay back up. Press palm into clay.
    • Press fingers into clay.
    • Press 1 finger into clay. Answer the questions for Task 2.
    • Sketch and explain the forces acting on the wedge/clay.
    • QUESTIONS:
    • TASK 2
    • Which is easier- flat end or pointed end? Why?
    • Which is easier- palm, all fingers, 1 finger? Why?
  • 6. SIMPLE MACHINES LAB Wheel & Axle Task 1
    • Materials: pencil, Simple Machines WS, Science Notebook, toe car, can opener, pre-made straw/string/cup wheel & axle
    • Procedure
    • TASK 1:
    • Rotate the wheels on the can opener. Observe. Answer questions on Task 1.
    • Rotate the wheels on the toy car. Observe. Answer questions on Task 1 card.
    • QUESTIONS:
    • TASK 1
    • How does the can opener open a can? (There are 3 machines here.)
    • Draw the wheel & axle(s) from the toy car.
  • 7. SIMPLE MACHINES LAB Wheel & Axle Task 2
    • Materials: pencil, Simple Machines WS, Science Notebook, toe car, can opener, pre-made straw/string/cup wheel & axle
    • Procedure
    • TASK 2:
    • Set up: Tape the cup to the table near the edge.
    • Rotate the straw to ‘wind up’ the string.
    • Try lifting the items with the wheel & axle.
    • QUESTIONS:
    • TASK 2
    • What items could you lift with the wheel & axle?
    • Sketch & explain the forces pulling up an object.
  • 8. SIMPLE MACHINES LAB Potential Energy
    • Materials: pencil, Simple Machines WS, Science Notebook, slinky, rubber band
    • Procedure
    • Think about the different forms of potential Energy & answer the following questions.
    • QUESTIONS:
    • What kinds of potential energy are in the following items?
    • Slinky, ball at the top of a hill, fire, sun, flute playing, battery, plutonium atom, rubber band
    E
  • 9. SIMPLE MACHINES LAB Lever Task 1
    • Materials: pencil, Simple Machines WS, Science Notebook, nails, hammer, wood
    • Procedure
    • Hammer the nail into the block of wood.
    • Use the back of the hammer as a lever to pull the nail out of the wood. (See teacher.)
    • Answer question for Task 1
    • QUESTIONS:
    • Task 1
    • Explain how you are able to take the nail out this way and not by your fingers.
  • 10. SIMPLE MACHINES LAB Lever Task 2
