Lesson Overview
Lesson Title:
Crash Test Dummy

Teachers:
Mr. John Huber (Primary)

Brief Description:
Today we will be going over Newton 3rd Law of Motion. We will first learn about what is the Law and then learn about real world situations.

Topics Introduced:
Newton 3rd Law

Lesson Information
Learning Expectations:

Science and Math Implications:
Students have to accurately use calculators for computing speed.
Students have to understand the principles of Newton's Three Laws of Motion.
Students apply scientific method to answer the question “Which material is the best to use for sidewalls?”
Technology and Engineering Implications:
Students have to understand the design of sidewalls and rails.

Plan Of Action:

Plan of action:
Students will learn about Newton's Laws and learn real world applications.

Procedures (The following is based on 88 min. block)
*Attention* This lab should be done AFTER a basic block of instruction on Newton’s Laws has been completed. A power point presentation is included for your convenience (see Newton’s Laws power point).

1st day:
Have an open discussion on what are Newton's laws.
Have students independently read from their text information on Newton’s laws. Use power point to give notes on Newton’s Three Laws.

2nd day:
Students conduct speed mini-lab.
Students rotate through friction mini-lab.
3rd day:
Inform students that they will be starting the "Crash Test Dummy" lab. The first part of the lab is to have the students test the ramps they will place 4 text books under the 50 cm piece of wood or metal, creating a ramp. The students will then take the Hot Wheel car and set it on the top of the ramp and let the car go, starting the stopwatch when released. When the car comes to rest students will stop the stopwatch. Students will re-test the lab several times to check for accuracy. Students will use an average for calculating speed.
4th day:
When all students have calculated their average car speed (S=d/t) they then begin formal lab report.
Students write up their formal lab report to address the problem, “Which material was best for sidewall?” Students create a hypothesis based on data collect from, test runs and knowledge gained from computer research, class notes, and text book readings. Experimental procedures indicate changes that need to be made.

5th day:
If students missed have them work on the lab and have the students that have done the lab lead them. Students will then finish their lab write up. Then test the students for understanding.
Extension
Use a different ramp or different material on the ramp to see how it affects the cars acceleration. You can also use different sizes of cars. Ask the students if the different material will affect the cars acceleration? Ask the students if the the different sizes of the car will affect the cars acceleration?

Data Set Used:


Data set:
· Forces, Motion, and Energy, (Holt, 2005).

Materials Needed:

Materials Needed:

A class set of Hot Wheels cars
A ramp constructed out of wood or metal 50cm long
3-5 Text books
A piece of foam 1 meeter long
A 2x4 piece of wood
A piece of metal 1 meeter long
A meeter stick.

Preparation Period:

Preparation Period:
You should construct the ramp for the cars and gather the material prier to doing the lab. In class time is minimal.

Implementation Period:

Implementation Period:
· Block (88 minute) schedule – 5 classes
· Daily (45 minute) schedule – 2 weeks

Science, Math, Engineering and / or Technology Implications:

Science, Technology, Engineering, and Math

Unexpected Results:

Unexpected Results:
You may have different results doing this lab on different floor surfaces, and using different angles.

Considerations for Diversity in Education:

Considerations for Diversity:
All students will participate in this lab.For higher learners you can have students calculate speed, slope, acceleration rate, and determine the forces used to mover the cars.
