Science Buddies' eighth grade science projects are the perfect way for eighth grade students to have fun exploring science, technology, engineering, and math (STEM). Our eighth grade projects are written and tested by scientists and are specifically created for use by students in the eighth 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, eighth 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: 4th-12th
By conducting their own survey of an outdoor environment, students will examine a method for assessing litter, identify how humans impact the environment, and design solutions for preventing marine debris. Read more
NGSS Performance Expectations:

Lesson Plan Grade: 6th-8th
Working as if they were engineers, students design and construct model solar sails made of aluminum foil to move cardboard tube satellites through "space" on a… Read more
NGSS Performance Expectations:
  • 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.
  • MS-PS2-2. Plan an investigation to provide evidence that the change in an object's motion depends on the sum of the forces on the object and the mass of the object.
  • MS-PS2-1.. Apply Newton's Third Law to design a solution to a problem involving the motion of two colliding objects.

Lesson Plan Grade: 3rd-12th
Plants have many crucial roles on our planet, and among these is the gas exchange that happens within their leaves. As plants take in carbon dioxide from our atmosphere, they release oxygen and retain the carbon. In this lesson, students will investigate leaves up close to look for the structures responsible for gas exchange. Read more

Lesson Plan Grade: 4th-12th
By using a model for how fishing affects marine life populations, students will construct explanations for one of the reasons why fish populations are declining. They will then work to design solutions for ways of making fisheries more sustainable for the animals and the people who depend on them. Read more

Lesson Plan Grade: 5th-10th
Why do birds migrate? How do seasonal changes in primary productivity influence the behaviors of higher order consumers like raptors? Visualize and explore the connectedness of organisms within and across ecosystems in this teacher-guided activity. Read more
NGSS Performance Expectations:
  • MS-LS2-2. Construct an explanation that predicts patterns of interactions among organisms across multiple ecosystems.
  • MS-LS2-3. Develop a model to describe the cycling of matter and flow of energy among living and nonliving parts of an ecosystem.
  • MS-LS2-4. Construct an argument supported by empirical evidence that changes to physical or biological components of an ecosystem affect populations.
