Science Buddies' seventh grade science projects are the perfect way for seventh grade students to have fun exploring science, technology, engineering, and math (STEM). Our seventh grade projects are written and tested by scientists and are specifically created for use by students in the seventh grade. Students can choose to follow the science experiment as written or put their own spin on the project.

For a personalized list of science projects, seventh graders can use the Science Buddies Topic Selection Wizard. The wizard asks students to respond to a series of simple statements and then uses their answers to recommend age-appropriate projects that fit their interests.

Lesson Plan Grade: 6th-8th
Students explore orbit transfers and, specifically, Hohmann transfers. They investigate the orbits of Earth and Mars by using cardboard and… Read more
Lesson Plan Grade: 6th-12th
In this activity, students are asked to create a change in air pressure using a garbage bag and vacuum cleaner, then create an illustration, model or concept map that explains what is happening. This activity is part of the KQED Engineering Is: Bringing Fish Up from the Deep e-book. The e-book explores the science and engineering principles behind the California Academy of Sciences' portable decompression chamber, and includes videos,… Read more

People have used boats to transport things around the world for thousands of years. Unfortunately, those boats can be vulnerable to stormy seas and they can capsize. This lesson expands on the classic "aluminum foil boat" project. Normally, students would build a boat from a sheet of aluminum foil and see how much weight it can hold—in still water—before sinking. In this project, they will find out how well their boats hold up to waves! Read more
NGSS Performance Expectations:
  • MS-ETS1-1. Define the criteria and constraints of a design problem with sufficient precision to ensure a successful solution, taking into account relevant scientific principles and potential impacts on people and the natural environment that may limit possible solutions.
  • MS-ETS1-2. Evaluate competing design solutions using a systematic process to determine how well they meet the criteria and constraints of the problem.
  • MS-ETS1-3. Analyze data from tests to determine similarities and differences among several design solutions to identify the best characteristics of each that can be combined into a new solution to better meet the criteria for success.
  • MS-ETS1-4. Develop a model to generate data for iterative testing and modification of a proposed object, tool, or process such that an optimal design can be achieved.

We hear the word "digital" all the time—digital technology, digital device, digital TV, etc. But what does it actually mean? In this lesson plan, your students will learn how digital signals allow us to reliably transmit and store information. Read more
NGSS Performance Expectations:
  • MS-PS4-3. Integrate qualitative scientific and technical information to support the claim that digitized signals are a more reliable way to encode and transmit information than analog signals.
Lesson Plan Grade: 6th-8th
Students explore adaptations by researching how animals, plants, and bacteria change based on their environment. They grow bacterial colonies in various environments and hypothesize how each environment will affect the cell culture size and color. After a day of pre-growth, the culture is spun down in a centrifuge and the cell pellet is analyzed. Finally, students research bacteria adaptations that allow them to survive in extreme environments then brainstorm… Read more

Add a twist to a traditional "build a catapult" engineering project with this fun lesson plan based on the 2018 global Fluor Engineering Challenge. Your students must build a device to launch a ball as far as possible—but they also have to build another device to catch it! With detailed rules and guidelines for a class-wide competition, this lesson is a great way to teach your students about the engineering design process. Read more

Lesson Plan Grade: 6th-8th
Your students will design, build, and race balloon-powered cars in this fun lesson plan that teaches about engineering design and kinetic and potential energy. Read more
NGSS Performance Expectations:
  • MS-PS3-5. Construct, use, and present arguments to support the claim that when the kinetic energy of an object changes, energy is transferred to or from that object.
  • MS-ETS1-4. Develop a model to generate data for iterative testing and modification of a proposed object, tool, or process such that an optimal design can be achieved.

How do plants know which way is up or down? How does this affect which direction their roots will grow? In this lesson plan, your students will investigate how changes in a plant's environment, like the direction of gravity, affect the shape of its growing roots over a period of several days. Read more
NGSS Performance Expectations:
  • MS-LS1-5. Construct a scientific explanation based on evidence for how environmental and genetic factors influence the growth of organisms.
Lesson Plan Grade: 6th-8th
Students use ultrasonic sensors and LEGO© MINDSTORMS© EV3 robots to emulate how bats use echolocation to detect obstacles. They measure the robot's reaction times as it senses objects at two distances and with different sensor threshold values, and again after making adjustments to optimize its effectiveness. Like engineers, they gather and graph data to analyze a given design (from the tutorial) and make modifications to the sensor placement and/or… Read more

How does light interact with matter? In this fun hands-on lesson, you students explore how different materials transmit, absorb and/or reflect light. They create their own experiments to demonstrate these phenomena and use a phones' built-in light sensor and Google's Science Journal app to add quantitative data to their arguments. Read more
NGSS Performance Expectations:
  • MS-PS4-2. Develop and use a model to describe that waves are reflected, absorbed, or transmitted through various materials.
