2. Scientific Questions OR NOT??? Scientists ALWAYS Have a PURPOSE!!

3. IS THIS A GOOD SCIENTIFIC QUESTION? 1.IS THE FINAL EXPERIMENT EDIBLE? 2.WHY DO WE NEED THE GLUE BECAUSE IT MIGHT CAUSE SOMETHING BECAUSE IT IS STICKY 3.HOW WILL THE GLUE AND STARCH FILL? 1.IS THE FINAL EXPERIMENT EDIBLE? 2.WHY DO WE NEED THE GLUE BECAUSE IT MIGHT CAUSE SOMETHING BECAUSE IT IS STICKY 3.HOW WILL THE GLUE AND STARCH FILL?

4. 4. WILL THE SUBSTANCE BUBBLE? 5. WHAT WILL HAPPEN WHEN THE SUBSTANCE MIXES? 6. WILL IT BE SOLID, LIQUID, OR GAS? 7. WHAT WILL WE NEED?

5. 8. HOW DOES THE FOOD COLORING MIX? 9. WHAT KIND OF TEXTURE WILL IT HAVE? 10. WILL IT BE A CHEMICAL OR PHYSICAL CHANGE? 11.WHAT WILL IT LOOK LIKE? 12. WHAT WILL HAPPEN WHEN THE STARCH AND GLUE REACT TO EACH OTHER? 13. WHAT IS GOING TO HAPPEN?

6. Writing A Good Hypothesis Using cause and effect and prediction to help you write hypotheses.

7. HYPOTHESIS  Hypothesis: this term refers to a researchers current understanding of the system she is investigating. Essentially, "stating your hypothesis" is saying "I think this is what's going on here..." followed by writing down a complete statement of what you know, what you understand, and how you have interpreted the evidence you have thus far evaluated.  Hypothesis: this term refers to a researchers current understanding of the system she is investigating.

8. PREDICTION  Prediction: this term refers to things that must be true if the hypothesis is correct. For example: Having watched dogs interact, we see that they understand one another, as if they are communicating. We can explain this by the hypothesis that dogs communicate through body language. That is, it's not all barks and growls. What things would have to be true if this hypothesis is correct? For one thing, there should be specific postures that are associated with specific behaviors. There should be postures that one dog adopts, that are followed by certain behaviors by the other dog. These are predictions that are useful in testing the hypothesis. We may not know what dog postures there are, but we predict that such postures should exist.

9. MODEL WRITING  PROBLEM QUESTION: What is it that caused the student to have a sore throat?  Hypothesis:  The sore throat probably was caused by a bacterial infection.  The sore throat probably occurred due to the screaming they did at the football game last night.  The sore throat was occurred because of a viral infection.  PROBLEM QUESTION: What is it that caused the student to have a sore throat?  Hypothesis:  The sore throat probably was caused by a bacterial infection.  The sore throat probably occurred due to the screaming they did at the football game last night.  The sore throat was occurred because of a viral infection.

10. You Try  Problem Question: What will happen when Baking soda and Vinegar are mixed together? Step 1: Make a prediction(what do you think will happen?) Step 2: Write a hypothesis(Why do you think it will work as you’ve predicted?)  Problem Question: What will happen when Baking soda and Vinegar are mixed together? Step 1: Make a prediction(what do you think will happen?) Step 2: Write a hypothesis(Why do you think it will work as you’ve predicted?)

11. Writing Scientific Conclusions  Pulling together what happened and analyzing the experiment you did. If your hypothesis is NOT correct, what could be the answer to your question? Summarize any difficulties or problems you had doing the experiment. What you do differently next time? List other things you learned. Do you have new questions?  Pulling together what happened and analyzing the experiment you did. If your hypothesis is NOT correct, what could be the answer to your question?
