Subject
Newton's Laws of Motion

Objective
1. Students will use internet resources to study develop and understanding of how forces and acceleration are related through Newton's Laws of motion.
2. Students will apply the knowledge they have acquired to design a device to prevent an raw egg from breaking when dropped from a specified height.
3. Apply this knowledge to solve problems using Newton's second law for a variety of situation

Science Standards: (List as applicable)
National Science Standards, Grades 9-12 Table 6.1
Physical Science; Motions and forces
Science as Inquiry
Science and Technology; abilities of technological design
History and Nature of Science; nature of scientific knowledge
Unififying Concepts and Processes; Evidence, models, and explanation

Description/What to do in the classroom
-Students will solve problems using Newton's laws of motion and answer questions from a work sheet on Newton's laws.
-Students will use TryScience.org and explore Forces in Nature.
-Students tried to break an egg by throwing it into a sheet with a hole. After this activity discuss why the egg did not break and how this can be intergrated into their designs
-Students working in teams will design a device which will hold a raw egg that will prevent the egg from breaking when dropped from a specified height.

Things to consider/science behind it
Students need to consider the affects of gravity on impact speed. Students need to consider air resistance, and what changes to their object in motion to reduce the net force acting on the object(an egg).

Curriculum topics
Physical Science
gravity
acceleration
Forces and Newton's Laws
conservation of momentum

Number of TryScience.org features used
0-5

Titles of TryScience.org features
1. Gravity in Action; Students discover gravity in action and how parachute increase air resistance
2. Eggs at rest Stay at Rest; Example of Newton's 1st law of motion
3. Speed Eggs and Slam; Save the egg, protet your "passenger" Example of application of Newton's laws of motion.

Materials Used
Worksheet of problem or problems assigned from book on Newton's laws of motion.

For the constructing of device to protect a raw egg from a free fall. Raw egg, straws, string, tape, craft sticks, paper, plastic bag and tape measure.

Computers with internet access

Results of student feedback and teacher assessment of activity
Students enjoyed this activity, and the winner safely dropped an egg from the top of the bleacher on the softball field. In addition, to dropping an raw egg I added an activity where students throw a egg into a sheet with a hole. The egg never breaks because of the effect of the sheet on the acceleration of the egg. I do not have computer access to worksheet or book assignment assigned to this lesson.
