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.

Do your students ever wish they could block out an annoying noise or music they don't like? In this fun lesson plan, they will design sound-insulating containers and measure how well they work using Google's Science Journal app. 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.
  • 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: 3rd-8th
Coming up with new ideas is hard! How do engineers design new things or improve existing ones? Engineers and inventors use different brainstorming techniques to help them think outside the box and come up with new ideas. In this lesson plan, your students will practice brainstorming with a method called SCAMPER. Read more
Lesson Plan Grade: 6th-8th
In this lesson plan, your students will build their own recycling sorting machines that use various methods, like magnets or puffs of air, to separate shreds of paper from paper clips. This lesson is inspired by the real-world engineering challenge of separating various materials, like paper, plastic, and metals, that get combined in single-stream recycling programs. 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.
  • MS-PS2-5. Conduct an investigation and evaluate the experimental design to provide evidence that fields exist between objects exerting forces on each other even though the objects are not in contact.
  • 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: 6th-12th
In this lesson plan, students will take a closer look at the most recent developments in gene editing. Specifically, they will learn about the CRISPR technology using various interactive simulations and other resources. Based on their gained knowledge, students will create a model of the CRISPR-Cas9 components and create a stop-motion animation video of the molecular mechanism of CRISPR-Cas9. Remote learning adaptation: This lesson plan can be conducted remotely. Students can work… Read more
NGSS Performance Expectations:
  • MS-LS4-5. Gather and synthesize information about technologies that have changed the way humans influence the inheritance of desired traits in organisms.
  • HS-LS1-1. Construct an explanation, based on evidence, for how the structure of DNA determines the structure of proteins, which carry out the essential functions of life through systems of specialized cells.
Lesson Plan Grade: 6th-8th
How is it possible that our eyes can see things that are not really there? In this fun lesson plan, your students will explore how our vision works with the help of two short experiments that involve some fascinating optical illusions. Let your students discuss why they see a hole in their hand, or why they see colors that were never there, and let them construct their own explanations. Read more
NGSS Performance Expectations:
  • MS-LS1-8. Gather and synthesize information that sensory receptors respond to stimuli by sending messages to the brain for immediate behavior or storage as memories.
Lesson Plan Grade: 6th-8th
In this lesson, students will model how traits are passed on from parents to their offspring by creating baby aliens based on their parents' traits. As students compare the physical features of their alien families, they will be able to make the connection between an organism's genotype and phenotype. Students will also learn the difference between dominant and recessive traits. Read more
NGSS Performance Expectations:
  • 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.
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.
Lesson Plan Grade: 6th-8th
Students use water balloons and a length of string to understand how the force of gravity between two objects and the velocity of a spacecraft can balance to form… 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.

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
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
