This resource accompanies our Rethink 7th Grade Science course. It includes ideas for use, ways to support exceptional children, ways to extend learning, digital resources and tools, tips for supporting English Language Learners and students with visual and hearing impairments. There are also ideas for offline learning.
Lesson plan that uses students' step length to understand the relationship between distance, speed and acceleration. Includes graphing of data and interpretation of graphs.
This video clip is meant to serve as a writing or discussion prompt during a unit on forces and motion. This can be used at varied grade levels, with the expectation that student responses would be more complex in higher grade levels.
This interactive resource is a compilation of text and other elements that serves as a multimedia learning experience for students. The resource defines average speed and demonstrates how to calculate it. Practice problems are provided.
Students design and build a balloon-powered car to better understand the science ideas related to rocket propulsion. They use ideas of mass and force to work out ways to improve the distance traveled by the car.
In this inquiry activity, students solve a 1D motion challenge in groups. Students build their own balloon rocket from the provided materials. They collect data and prepare a position vs. time graph of their data and determine the average velocity of the rocket.

CK-12 Physical Science Concepts covers the study of physical science for middle school students. The 5 chapters provide an introduction to physical science, matter, states of matter, chemical interactions and bonds, chemical reactions, motion and forces, and the types and characteristics of energy.
This interactive resource is a compilation of text and other elements that serves as a multimedia learning experience for students. The resource describes how graphs can be shown to illustrate motion.
This resource is a compilation of text, videos, and other elements that serves as a multimedia learning experience for students. The resource reviews types of forces and how force affects motion.
Students will connect the motion of an object to the corresponding position-time and velocity-time graphs to determine the velocity traveled during different time intervals.
In this lesson, students will connect the motion of an object to the corresponding position-time and velocity-time graphs to determine the velocity traveled during different time intervals.
Sample Learning Goals
Explain the Conservation of Mechanical Energy concept using kinetic energy (KE) and gravitational potential energy (PE).
Describe how the Energy Bar and Pie Charts relate to position and speed.
Explain how changing the Skater Mass affects energy.
Explain how changing the Track Friction affects energy.
Predict position or estimate speed from Energy Bar and Pie Charts.
Calculate speed or height at one position from information about a different position.
Calculate KE and PE at one position from information about a different position.
Design a skate park using the concepts of mechanical energy and energy conservation.
In this lesson, students will investigate motion through a variety of activities in order to odentify changes in position and direction and the speed of an object. Students will also graph changes in motion.
Students are tasked with moving a 20 gram (or other low denomination) weight a distance of one meter using a “Sphero*” remote controlled robot. Students use available materials to design and build a structure that will allow the sphero to push or pull the weight, while allowing for factors such as friction, direction, and gravity. *Note: Although students can issue specific commands in the Sphero software, this activity only requires that they be able to “drive” the Sphero, thus providing the force to move the weight.
Sample Learning Goals
Relate the gravitational force to masses of objects and distance between objects.
Explain Newton's third law for gravitational forces.
Use measurements to determine the universal gravitational constant.
