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
Have your students read about autonomous (also called self-driving or driverless) cars in the news? How can you build a car or a robot that will stay on the road without a human driver? In this project, your students will find out by building a robot that can automatically follow a line around a homemade race course, while learning about the electromagnetic spectrum and electronic circuits.

NGSS Performance Expectations:
  • MS-PS4-2. Develop and use a model to describe that waves are reflected, absorbed, or transmitted through various materials.

Why is the ocean vital to our planet? There are many reasons, but one important one is that the ocean is a major player in regulating our weather and climate through currents. In this lesson plan, your students will model ocean currents with cups, water, and food coloring, and explore how temperature and density differences set deep ocean waters in motion to create a global oceanic circulation system. Read more
NGSS Performance Expectations:
  • MS-ESS2-6. Develop and use a model to describe how unequal heating and rotation of the Earth cause patterns of atmospheric and oceanic circulation that determine regional climates.

Lesson Plan Grade: 6th-8th
Does human activity impact the environment? If so, how can we measure our impact on the environment? How can we use these measurements to change our behavior? In this project, your students will explore these questions by designing and building an electronic circuit that can measure environmental parameters like water quality or light pollution. Read more
NGSS Performance Expectations:
  • MS-ESS3-3. Apply scientific principles to design a method for monitoring and minimizing a human impact on the environment.

Explore genetic variation through the world of taste in this problem-solving lesson plan. Working both individually and collaboratively, students figure out what kind of tasters they are, what this means about their own genetics, and how genetic mutations can lead to functional differences. This activity provides a hands-on, personalized opportunity to learn about how genotypes and phenotypes align. Read more
NGSS Performance Expectations:
  • MS-LS3-1. Develop and use a model to describe why structural changes to genes (mutations) located on chromosomes may affect proteins and may result in harmful, beneficial, or neutral effects to the structure and function of the organism.
  • MS-LS3-2. Develop and use a model to describe why asexual reproduction results in offspring with identical genetic information and sexual reproduction results in offspring with genetic variation.

Learn about potential and kinetic energy the fun way—by launching ping pong balls across the classroom with a catapult! 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 the object.

Lesson Plan Grade: 6th-8th
In this small group activity, students will build a plant seed (burr) from a Styrofoam® ball and other crafts materials. The seed needs to be designed in a way that it can be dispersed by attaching to a mockup animal (wool glove). Students will first test if their seed attaches to the wool glove and then carry their attached seed along an obstacle course inside the classroom. As students design their plant seed and mimic its dispersal via an animal, they will realize how some plants grow… Read more
NGSS Performance Expectations:
  • MS-LS1-4. Use argument based on empirical evidence and scientific reasoning to support an explanation for how characteristic animal behaviors and specialized plant structures affect the probability of successful reproduction of animals and plants respectively.

  • MS-ETS1-2. Evaluate competing design solutions using a systematic process to determine how well they meet the criteria and constraints of the problem.

Lesson Plan Grade: 4th-8th
Would it be possible to power everything in your classroom using clean, renewable solar power? Inspired by Global Problem Solvers: The Series, in this lesson plan, your students will research and design a solar power system for a mobile classroom that can be used after natural disasters or in remote areas without permanent schools. This lesson is one of three independent lesson plans inspired by Global Problem Solvers: The Series. You can read more about the series and the lesson plans… Read more
NGSS Performance Expectations:
  • 3-5-ETS1-1. Define a simple design problem reflecting a need or a want that includes specified criteria for success and constraints on materials, time, or cost.
  • 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.

Lesson Plan Grade: 6th-8th
Plants carry out photosynthesis to produce sugars that they need as an energy source to live and grow. During photosynthesis, oxygen—a gas that many living beings need to survive—is released. This makes photosynthesis one of the most important biological processes on Earth. In Part 1 of this lesson plan, students will utilize the floating leaf disk assay to demonstrate the production of oxygen gas during photosynthesis. They will then continue to design and conduct their own… Read more
NGSS Performance Expectations:
  • MS-LS1-6. Construct a scientific explanation based on evidence for the role of photosynthesis in the cycling of matter and flow of energy into and out of organisms.

How can technology and the internet help us solve some of the world's most pressing problems? Your students might not be ready to tackle global poverty or world peace, but they can start small by identifying a social problem in their local community. In this lesson plan they will design a solution to a problem of their choice that uses technology. It could be anything from a GPS-enabled dog collar to track lost pets, to an app that notifies local food banks when people have extra fruits and… Read more

  • 3-5-ETS1-2. Generate and compare multiple possible solutions to a problem based on how well each is likely to meet the criteria and constraints of the problem.
  • 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.
