1. Students Will Be Able To (SWBAT):  Define: Hypothesis, Null Hypothesis, Procedure, Opinion and Bias  Develop a hypothesis using “If… then…because..”  Develop a null hypothesis using “If… then…because..” Essential Question: How can we make engines more efficient?

2. Do Now: Using the number that you were assigned please retrieve your assigned textbook.

3. Journal Entry- Please turn to page 5 in your blended Science booklet Using a dictionary define the following words: Hypothesis Null Hypothesis Procedure Opinion Bias

4. Essential Question: How can we make engines more efficient? Independent Work: Develop your own hypothesis based on the essential question. Please use (if..then..because…)

5. Essential Question: How can we make engines more efficient? Group Work- page 7 As a group, write down a hypothesis and a null hypothesis that you all agree with based on the essential question. Please use (if..then..because…)

6. Independent Work- Key Words (use your notes) Define the following: Experiment Observe Qualitative data Quantitative data

7. Students Will Be Able To (SWBAT):  Understand why it is important to have accuracy, honesty, quality and care when collecting data.  Collect data and record data to answer the following essential question: “How much effort mass is required to move various resistance masses?”  Use mathematical skills to find the average effort mass. Essential Question: How much effort mass is required to move various resistance masses?”

8. Journal Entry: Blended Science Booklet page 8 Data Collection Explain in your own words why accuracy, honesty, quality and care are important when collecting data.

9. Why accuracy, honesty, quality and care are important when collecting data? When you perform the procedure you have to collect data with charts, graphs, and other math skills. Collecting data helps you put together your conclusion. Scientists use the metric system to measure their units. Data is important because in order to duplicate an experiment they'd need the precise measurements

10. Why do we need 3 trials for all experiments?

11. Procedure page 9 Retrieve your blended science bin. Set up your string and binder clip system. (refer back to pages 2 and 3)

12. Materials needed today… 3 Large binder clips 2 small paper clips Kite string 2 slotted mass ( two hooks with weights) Lid from your blue bin

13. Journal Entry Based on the picture below, who or what would represent the effort mass and who or what would represent the resistance mass. Why? 500lbs 200lbs

14. What we are testing today… Essential Question: How much effort mass is required to move various resistance masses? Effort mass (mass used to move a higher massed object) Resistance mass (mass that is trying to be moved) 500lbs200lbs

15. Observations 100g150g200g250g Effort Mass Trial 1 Effort Mass Trial 2 Effort Mass Trail 3 Mean Effort Mass Mechanical Effort Mass (Resistance Mass/ Mean Effort Mass) Resistance Mass in Grams

16. How to find an average?

17. On page 12 Write down at least 3 questions that come up during the course of this experiment.

18. Discussion Questions- Talk with your team and write your individual responses. What is the difference between effort mass and resistance masses? How is it possible for a lower effort mass to move a higher resistance mass?
