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: 6th-8th
Learn about real space flight and Newton's laws of motion with this fun lesson! This new twist on a classic project lets your students build a multi-stage balloon rocket that they can launch across the classroom. Read more
NGSS Performance Expectations:
  • 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-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.
Lesson Plan Grade: 6th-8th
Don't just teach your students about Newton's laws of motion using diagrams in a textbook — try something hands-on! In this project, students will build their own cars using craft materials and explore the relationship between force, mass, and acceleration. Students can graph data and make observations in real-time using Google's Science Journal app or use a low-tech approach with a meter stick and stopwatch. Read more

Lesson Plan Grade: 6th-8th
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.
Lesson Plan Grade: 6th-8th
The egg drop project is a time-honored tradition in many science classrooms. Students build a device to protect an egg and prevent it from breaking when dropped. This project typically relates to lessons about Newton's laws of motion or potential and kinetic energy. However, it is also a great way for students to practice the engineering design process, and learn about the importance of design iteration and learning from failure. Read more

In this fun lesson plan, students will measure how the amount of carbon dioxide in their exhaled breath changes with exercise levels. Carbon dioxide is a product of cellular respiration, so the lesson highlights how breathing is connected to cellular respiration and energy production in our body. They will make the measurements using a simple colorimetric test and a phone with Google's Science Journal app. Read more
NGSS Performance Expectations:
  • MS-LS1-7. Develop a model to describe how food is rearranged through chemical reactions forming new molecules that support growth and/or release energy as this matter moves through an organism.
Lesson Plan Grade: 6th-12th
Scientists are concerned that climate change could cause the spread of mosquito populations that carry diseases like malaria, West Nile virus, Zika virus, and dengue fever. In this lesson plan, your students will access real-world data on mosquitoes at different locations throughout the United States, and examine the effects of temperature on mosquito populations. Remote learning adaptation: This lesson plan can be conducted remotely. Students can work independently on the Explore section of… Read more
NGSS Performance Expectations:
  • MS-LS2-4. Construct an argument supported by empirical evidence that changes to physical or biological components of an ecosystem affect populations.
  • HS-LS2-1. Use mathematical and/or computational representations of phenomena or design solutions to support explanations of factors that affect carrying capacity of ecosystems at different scales.

What happens when you get food poisoning or the flu? How does our body fight an infection when we get sick? In this lesson, students will build a model of our immune system to find out how our body responds to invading bacteria or viruses that cause diseases and to investigate the role of memory cells. Read more
NGSS Performance Expectations:
  • MS-LS1-3. Use argument supported by evidence for how the body is a system of interacting subsystems composed of groups of cells.
Lesson Plan Grade: 6th-8th
Aircraft carriers are much shorter than a typical airport runway. How do airplanes manage to gain enough speed for takeoff over such a short distance? A catapult gives them an extra boost! In this lesson, your students will practice engineering design as they build their own paper airplane launchers, while learning about kinetic and potential energy. Read more
NGSS Performance Expectations:
  • MS-PS3-2. Develop a model to describe that when the arrangement of objects interacting at a distance changes, different amounts of potential energy are stored in the system.

  • 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.
