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
Making an electromagnet from a battery, nail, and wire is a classic science demonstration. But instead of just demonstrating this for your students, let them explore it themselves! In this lesson they will discover how different variables affect the strength of an electromagnet. Read more
NGSS Performance Expectations:
  • MS-PS2-3. Ask questions about data to determine the factors that affect the strength of electric and magnetic forces.

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
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
NGSS Performance Expectations:
  • 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-ETS1-4. 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.

What would your students do if your town's water supply was cut off due to an equipment failure or natural disaster? Inspired by Global Problem Solvers: The Series, in this lesson plan they will tackle a real-world engineering challenge by building a prototype of a device that can manually pump water during an emergency. They will also think like entrepreneurs and come up with a business plan for how their device could be produced, sold, and used in the real world. This lesson is one of… 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.
  • 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.
  • 3-5-ETS1-3. Plan and carry out fair tests in which variables are controlled and failure points are considered to identify aspects of a model or prototype that can be improved.
  • 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-ETS1-4. 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-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
Lesson Plan Grade: 6th-8th
Why can we feel gravity pull us down towards the Earth, but not sideways towards other big objects like buildings? Why do the planets in our solar system orbit the sun instead of flying off into space? In this lesson plan your students will develop a model for gravity and use it to explore answers to these questions. Read more
NGSS Performance Expectations:
  • MS-PS2-4. Construct and present arguments using evidence to support the claim that gravitational interactions are attractive and depend on the masses of interacting objects.
  • MS-ESS1-2. Develop and use a model to describe the role of gravity in the motions within galaxies and the solar system.
Lesson Plan Grade: 6th-8th
Can one type of rock turn into another type of rock? In this lesson plan, your students will explore the rock cycle and model it using crayons. Can they turn a sedimentary "rock" made from crayon shavings into a metamorphic rock? What about an igneous rock? Try this lesson to find out! Read more
NGSS Performance Expectations:
  • MS-ESS2-1. Develop a model to describe the cycling of Earth's materials and the flow of energy that drives this process.
Lesson Plan Grade: 6th-12th
What is R naught (R₀), what factors influence it, and how does it shape the infection curves of an epidemic? Students will explore these questions and more in this lesson plan. They will then use SimPandemic, a free online tool, to model what a COVID-19 outbreak looks like in communities with different R₀ values. Remote learning adaptation: This lesson plan can be conducted remotely. Students can work independently on the Explore section of the lesson plan using the Student… 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-LS2-8. Evaluate evidence for the role of group behavior on individual and species' chances to survive and reproduce.
Lesson Plan Grade: 6th-8th
This hands-on science lesson will help your students get a more accurate view of the solar system by making a scale model. They will do the calculations, make model planets, and find out where to place them so their model reflects reality. Seeing the relative size of the eight planets and their distance from the Sun displayed before them will allow your students to grasp the structure and vastness of the solar system. Read more
NGSS Performance Expectations:
  • MS-ESS1-3. Analyze and interpret data to determine scale properties of objects in the solar system.
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 string. Students learn… Read more
NGSS Performance Expectations:
  • MS-ESS1-2. Develop and use a model to describe the role of gravity in the motions within galaxies and the solar system.
