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 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.
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.
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.

More than 155 planets have been found outside of our solar system since the first extra-solar planet was identified in 1995. The search has long been heavily biased towards finding massive planets with short orbits. Now, to find an Earth-like planet, scientists are looking for a planetary setup that is similar to our own, in which a Jupiter-like planet lies a good distance away from its sun. This video segment adapted from NOVA explores how the arrangement of planets in our solar system may have affected the development of life on Earth.

Play with objects on a teeter totter to learn about balance.
- Predict how objects of various masses can be used to make a plank balance.
- Predict how changing the positions of the masses on the plank will affect the motion of the plank
- Write rules to predict which way plank will tilt when objects are placed on it.
- Use your rules to solve puzzles about balancing.
