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?
Science The previous questions have not yet
been answered by science

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.
How Does Science Answer Questions? Scientific Method
Example Dead Sea
What do we observe? What is the question?
How Does Science Answer Questions Hypothesis Experiment
Example Dead Sea
What is the hypothesis? What is the independent variable? What is the dependent variable?
How Does Science Answer Questions Experimental Design
Example Dead Sea
Which sample was the control group? Which samples were the experimental groups? What were the constants?
How Does Science Answer Questions Results
Example Dead Sea
How did we collect data? How did we organize data? How will we analyze data?

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
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)

Lab Report
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!
