1. Claim, Evidence, and Reasoning How to conduct a scientific investigation

2. Claim Most scientific investigations originate with a guiding question. Your claim is the concluding statement that answers your original question. ●The claim is usually one sentence in length. ●It must be accurate, specific, and completely answer the question.

3. Evidence The evidence is all of the scientific data that supports your claim. ●Evidence must be sufficient and relevant to your claim. Not all data is considered evidence! ●Most evidence is specific data from the lab or experiment. This can come from your own group or another group in the class.

4. Evidence The evidence is all of the scientific data that supports your claim. ●It can also come from other sources such as: computer simulations, websites, textbook, class notes, personal experience, etc. ●It is important to have numerous pieces of evidence in order to prove your claim!

5. Reasoning Reasoning is the explanation that connects your claim to the evidence that supports it. ●It shows why the data you chose counts as evidence. ●This explanation acts as a “conclusion” of your experiment.

6. Reasoning Reasoning is the explanation that connects your claim to the evidence that supports it. ●It shows a detailed understanding of the scientific principles involved and uses correct science vocabulary. ●The reasoning should usually be at least a few sentences in length.

7. Real-World Claims People make claims all of the time. Friends, parents, and just about every commerical on TV is making a claim about something. Write down at least 4 claims you have heard recently. Share those claims with your partner.

8. List of claims

9. LET’S PRACTICE We will practice using a couple of real world example. 1)We will read the question. 2)We will write a claim, based on that question. 3)We will write down at least 3-4 pieces of evidence that support your claim. 4)We will provide a reasoning that explains why we used the evidence we did to determine the "best".

10. Now you will do one on your own Pick one of the following topics, then everyone with the same topic will be in a group. (no more than five per topic). You will then develop a question, write a claim, find evidence backing your claim and write a reasoning statement. 1)best football/basketball/baseball player 2)best movie/t.v show of all time 3)best car/truck on the road 4)best flavor of ice cream/food 5)best University/sports team of all time
