Eighth Grade Lesson Plans (122 results)

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.

Let us help you find a science project that fits your interests, with our Topic Selection Wizard.

Teach your students how to make plastic out of milk in this hands-on lesson plan! You will conduct a simple milk-transforming experiment to explore how plastics can be derived from a natural resource such as milk. Students will perform their own experiments and can even create a product from their resulting organic casein polymer. Read more
NGSS Performance Expectations:
  • MS-PS1-2. Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.
  • MS-PS1-3. Gather and make sense of information to describe that synthetic materials come from natural resources and impact society.

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
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.

When light interacts with an object, it can be absorbed, transmitted, or reflected. This lesson focuses on materials that reflect light. Specifically, students will use mirrors and flashlights to investigate how light is reflected from a surface. By doing that, they will discover that when a light ray hits a reflective surface, its angle of incidence is equal to the angle of reflection, which is stated by the law of reflection. Students will then use their gained knowledge in a mirror maze… 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-ETS1-4. Develop a model to generate data for the iterative testing and modification of a proposed object, tool, or process such that an optimal design can be achieved.

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.
