1. Using Inferences to Make a Hypothesis
Students will use inferences to make hypothesis

2. Warm-Up: Pictures
Look at three pictures. Try to guess what the pictures are and explain why you think so.

3. Science Careers: Archaeology

4. Vocabulary
Inference- Something that you already know about a problem. Hypothesis- An educated guess using inferences.

5. Where are inferences from?
Inferences can come from accepted knowledge
Examples: Bears poop in the woods, fire is hot, the sky is blue, etc….
Inferences can come from observations
Examples: Peter makes noise when he is bored, Ariana smiles a lot, Jashone likes food.

6. Activity: Dino Prints
Look at 3 pictures of dino prints. Try to put the prints so that they match up with each other. Your job as a paleontologist (ancient scientist) is to tell the story of what happened using these fossilized footprints.

7. What is the story?

8. Inferences- Things that I already know about dinosaurs or things I observed when looking at the picture.

9. Inferences- Things that I already know about dinosaurs or things I observed when looking at the picture.
Ex: Some dinosaurs are carnivores Bigger dinosaurs eat smaller dinosaurs Two sets of footprints go into frame two, one set of footprints comes out

10. Make a Hypothesis…..
Use your inferences:

11. Another Example….
Key question: Why do all of the plants grow in the same direction?
Observation: What can you see when you look at the plants?
Inferences: What do you know about plants that might explain why this happens?
Hypothesis: Answer the key question using your inferences.

12. Extension…..
What could we do to test your hypothesis?
