1. Unit 1 (Scientific Skills), Day 5 Experimental Design

2. Catalyst  Expectations  Done in your notebook silently  Date 8/30  Catalyst Question  Why do we sleep?  Why do we dream?  Why are we ticklish?  Why do we smile?  Why do we yawn?  Why are there lefties and righties?

3. Science  The previous questions have not yet been answered by science

4. New Seating Chart  Find a Seat  Mrs. Larkin will tell you the new seats when class begins

5. Catalyst  Expectations  Done silently  Date your page 9/3 or 9/4  The Tortoise and the Hare - Graphing  The tortoise and the hare have a race against each other. The tortoise walks at a slow but consistent pace. The hare runs quickly, takes a long break, runs quickly, takes a long break, etc. Eventually, the tortoise wins (slow and steady wins the race!). Graph the distance vs. time showing the tortoise and the hare.

6. How Does Science Answer Questions?  Scientific Method

7. Example  Dead Sea  What do we observe?  What is the question?

8. How Does Science Answer Questions  Hypothesis  Experiment

9. Example  Dead Sea  What is the hypothesis?  What is the independent variable?  What is the dependent variable?

10. How Does Science Answer Questions  Experimental Design

11. Example  Dead Sea  Which sample was the control group?  Which samples were the experimental groups?  What were the constants?

12. How Does Science Answer Questions  Results

13. Example  Dead Sea  How did we collect data?  How did we organize data?  How will we analyze data?

14. Collecting and Organizing Data

15. Analyzing Data

16. Project  Title: Too Fly for Junior High  Unit: #1 – Scientific Skills  Driving Question: How can we, as scientists, use the scientific method to create the furthest flying paper airplane?  Description: This project has three phases  First Due Date: Friday 9/6: Best airplane design

17.  Phase 1: Students will research five different paper airplane models and determine which flies the furthest. Constraints: students may only use 8.5” by 11” computer paper.  Phase 2: Students will modify their best paper airplane in a single MEASURABLE way. They will create 5 models that incrementally change this measurable part. Constraints: cardstock, glue, tape, paper clips.  Phase 3: Students will design the paper airplane to reflect their personalities and to appeal to children. They will market this in a presentations as a toy. There will be a final race to determine who has the furthest flying plane. (Best Flight and Best in Show)

18. Deliverables  Group Deliverables  5 research models (Phase I)  5 scientific method models (Phase 2)  Final Model (Phase 3)  Individual Deliverables  Lab Report

19. Today’s Task (Phase I)  Choose who will be the following:  Designer – In charge of ensuring quality of airplane decoration  Engineer – In charge of ensuring quality of airplane construction  Data Analyst – In charge of ensuring quality of data  If you have a fourth person, additional role  Presenter – In charge of organizing presentation  Note: All students are required to participate in all four parts. However, the designated person is the “boss” and delegates work. You will be grading each other on fulfilling the roles!

20. Today’s Task (Phase I)  Research the best paper airplane model  You need to try five of them
