  1. Science The Scientific Method: Lesson 2: The Scientific Method (bag experiment)

  2. The BIG Question: How do scientists attempt to explain our world?

  3. Why do the leaves change color in the fall? What causes the leaves to drop from a tree?

  4. The BIG Question: What are the steps scientists use to find answers to their questions?

  5. The Scientific Method

  6. Step 1: Ask a question.

  7. What will happen if I poke a pencil through a full bag of water?

  8. Step 2: I think… Make a hypothesis.

  9. What will happen if I poke a pencil through a full bag of water? I think…

  10. Step 3: Design and perform the experiment.

  11. 1. Fill a small plastic bag with water and seal it. 2. Slowly poke a pencil through the bag.

  12. Step 4: Record and analyze the data.

  13. 1. Fill a small plastic bag with water and seal it. 2. Slowly poke a pencil through the bag.

  14. No water leaked from the bag!

  15. Step 5: Draw a conclusion.

  16. No water leaked from the bag!

  17. The pencil made a hole that was only wide enough for the pencil to fit through. There was no extra space around the pencil for the water to leak out.

  18. Sum it up! What did you learn today?
