**Subject Area:**Science

**Grade:**6

**Body of Knowledge:**Physical Science

**Idea:**Level 2: Basic Application of Skills & Concepts

**Big Idea:**Forces and Changes in Motion - A. It takes energy to change the motion of objects.

B. Energy change is understood in terms of forces--pushes or pulls.

C. Some forces act through physical contact, while others act at a distance.

Clarification for grades K-5: The target understanding for students in the elementary grades should focus on Big Ideas A, B, and C.

Clarification for grades 6-8: The target understanding for students in grades 6-8 should begin to transition the focus to a more specific definition of forces and changes in motion. Net forces create a change in motion. A change in momentum occurs when a net force is applied to an object over a time interval.

Grades 9-12, Standard 12: Motion - A. Motion can be measured and described qualitatively and quantitatively. Net forces create a change in motion. B. Momentum is conserved under well-defined conditions. A change in momentum occurs when a net force is applied to an object over a time interval.

## STEM Lessons - Model Eliciting Activity

Students will design specific nose cones for a water bottle rocket. They will test them to find out and rate which one is most effective in terms of accuracy, speed, distance, and cost effectiveness. This information will be used as criteria for a company that designs nose cones for orbitary missions.

Model Eliciting Activities, MEAs, are open-ended, interdisciplinary problem-solving activities that are meant to reveal students’ thinking about the concepts embedded in realistic situations. Click here to learn more about MEAs and how they can transform your classroom.

Students are asked to evaluate and test several rocket fin designs to determine the most effective design. After launch, the students are asked to test an additional design and also design their own rocket fin. Additionally, students will record and graph their results.

The main problem students will need to solve is helping Lily Rae Wridenhoud find a route that will afford her the quickest time, least distance and highest customer satisfaction rating. Students will be given a map of all the streets leading around the neighborhood and customer rating (smiley faces). Students will need to use a ruler to figure out distances as well as decide elevation numbers on the topographic map. Then they will write out the route they have chosen to give Lily, and write a short explanation as to why this is the quickest and least distance traveled. Students will then be asked to look over their findings and be informed that some of the old clients have canceled the paper delivery and a few new paper clients have signed on. Does their new route still fit their findings?

The students will be asked to help a company choose a design to market for their new business. The company gives students four prototypes to begin with, but asks the students to create one of their own if they wish to further the research. After choosing one of the models and writing a report to declare their findings and explain their reasoning, students will then be given restrictions to the parachute. They are asked to find a material that is light yet strong, and resistant to tearing and breaking. Students will have to create parachutes using the chosen model but made with different materials to establish the best overall material.

In this MEA, students will select the robots that are more efficient at doing a certain type of job. They will have to analyze data tables that include force, force units, mass, mass units, and friction.

This MEA uses prior knowledge of Newton's Three Laws of Motion and has students design the best skateboard for different clients.
