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.

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?

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)

Deliverables Group Deliverables

5 research models (Phase I) 5 scientific method models (Phase 2) Final Model (Phase 3)

Individual Deliverables 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!
