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
In this Model-Eliciting Activity (MEA), the students follow the engineering process to assist Worldwide Food Distribution Mission improve their food delivery device in order to deliver food to remote parts of the world.
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. MEAs resemble engineering problems and encourage students to create solutions in the form of mathematical and scientific models. Students work in teams to apply their knowledge of science and mathematics to solve an open-ended problem while considering constraints and tradeoffs. Students integrate their ELA skills into MEAs as they are asked to clearly document their thought processes. MEAs follow a problem-based, student-centered approach to learning, where students are encouraged to grapple with the problem while the teacher acts as a facilitator.

This Model Eliciting Activity (MEA) is written at a 5th grade level. Clean Dat "SPACE" MEA provides students with an engineering problem in which they must work as a team to design a procedure to select the best space junk cleanup company for the purpose of keeping the International Space Station safe while in orbit.

This MEA asks students to assist Ms. Joy Ride who is creating a virtual TV series about extreme roller coasters. They work together to determine which roller coaster is most extreme and should be featured in the first episode. Students are presented with research of five extreme roller coasters and they must use their math skills to convert units of measurements while learning about force and motion.

Virtual Manipulatives
This virtual manipulative will help the students learn some important concepts of classical mechanics, such as gravitational acceleration, energy conservation and so on. This activity will also help in students learning via the process of making predictions (about number of pendulum swings), discussing outcomes and sharing results.
Type: Virtual Manipulative
Friction is important in enabling the movement of objects. Friction is a force that acts in an opposite direction to movement. Friction is everywhere when objects come into contact with each other. Observe what happens when the surfaces are very smooth or slippery, it reduces the friction and thus it makes harder to stop the motion.
Type: Virtual Manipulative
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.
Type: Virtual Manipulative
Students can create an applied force and see how it makes objects move. They can also make changes in friction and see how it affects the motion of objects.
- Identify when forces are balanced vs. unbalanced.
- Determine the sum of forces (net force) on an object with more than one force on it.
- Predict the motion of an object with zero net force.
- Predict the direction of motion given a combination of forces.
