Try the new "Ladybug Motion 2D" simulation for the latest updated version. Learn about position, velocity, and acceleration vectors. Move the ball with the mouse or let the simulation move the ball in four types of motion (2 types of linear, simple harmonic, circle).

Students design, build and evaluate a spring-powered mouse trap racer. For evaluation, teams equip their racers with an intelligent brick from a LEGO© MINDSTORMS© NXT Education Base Set and a HiTechnic© acceleration sensor. They use acceleration data collected during the launch to compute velocity and displacement vs. time graphs. In the process, students learn about the importance of fitting mathematical models to measurements of physical quantities, reinforce their knowledge of Newtonian mechanics, deal with design compromises, learn about data acquisition and logging, and carry out collaborative assessment of results from all participating teams.

The focus of this unit is to introduce the concepts of force and motion. Specifically this unit will address the forces of push, pull, gravity, and work. It also introduces students to the concepts of friction and slope. The unit begins with an introduction to the scientific method and addresses the differences between scientists and engineers. Students will be both scientists and engineers while completing this unit.

Student engineers learn to understand force and motion and how it is effected by slope, design and weight carried.

Mechanical energy is the most easily understood form of energy for students. When there is mechanical energy involved, something moves. Mechanical energy is a very important concept to understand. Engineers need to know what happens when something heavy falls from a long distance changing its potential energy into kinetic energy. Automotive engineers need to know what happens when cars crash into each other, and why they can do so much damage, even at low speeds! Our knowledge of mechanical energy is used to help design things like bridges, engines, cars, tools, parachutes, and even buildings! In this lesson, students will learn how the conservation of energy applies to impact situations such as a car crash or a falling object.

This lesson covers the topic of muscles. Students learn about the three different types of muscles in the human body and the effects of microgravity on muscles. Students also learn how astronauts need to exercise in order to lessen muscle atrophy in space. Students discover what types of equipment engineers design to help the astronauts exercise while in space.

In this activity, students read cards about various civil rights protests and events during the 1940s. For each event, students match the issue (voting rights, fair employment, fair housing, or segregation in public places) at stake, identify the key people involved and what region of the country it took place in. After students have completed all the cards, an optional writing task asks students to synthesize the historical content by writing a letter to a relative serving overseas describing the efforts of civil rights activists in the 1940s. There is some assembly of materials required for this activity. This activity has optional Smartboard elements but can be completed without a Smartboard.

This activity helps students understand the significance of programming and also how the LEGO MINDSTORMS(TM) NXT robot's sensors assist its movement and make programming easier. Students compare human senses to robot sensors, describing similarities and differences.

The purpose of this task is for students to solve problems involving decimals in a context involving a concept that supports financial literacy, namely inflation.

In a class demonstration, students observe a simple water cycle model to better understand its role in pollutant transport. This activity shows one way in which pollution is affected by the water cycle; it simulates a point source of pollution in a lake and the resulting environmental consequences.

The purpose of this task is to engage students in an open-ended modeling task that uses similarity of right triangles, and also requires the use of technology.

This problem uses the same numbers and asks similar mathematical questions as "6.NS The Florist Shop," but that task requires students to apply the concepts of multiples and common multiples in a context.

Using cards with integers on them to practice multiplying and dividing integers. This resource links to the teacher's lesson plan. You can find the other parts (including student materials) in the Grade 7 Module 2 archive: https://goopenct.org/courses/grade-7-module-2-rational-numbers

Students are introduced to the parameters of an engineering challenge in which their principal has asked them to devise an invisible security system to cost-effectively protect a treasured mummified troll, while still allowing for visitor viewing during the day. Students generate ideas for solving the grand challenge, first independently, then in small groups, and finally, compiled as a class.

This activity helps students learn about the three different types of muscles and how outer space affects astronauts' muscles. They will discover how important it is for astronauts to get adequate exercise both on Earth and in outer space. Also, through the design of their own microgravity exercise machine, students learn about the exercise machines that engineers design specifically for astronaut use.

Students are introduced to the field of biomechanics and how the muscular system produces human movement. They learn the importance of the muscular system in our daily lives, why it is important to be able to repair muscular system injuries and how engineering can help.

This problem requires a comparison of rates where one is given in terms of unit rates, and the other is not.
