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
Students use ultrasonic sensors and LEGO© MINDSTORMS© EV3 robots to emulate how bats use echolocation to detect obstacles. They measure the robot's reaction times as it senses objects at two distances and with different sensor threshold values, and again after making adjustments to optimize its effectiveness. Like engineers, they gather and graph data to analyze a given design (from the tutorial) and make modifications to the sensor placement and/or threshold values in… Read more
NGSS Performance Expectations:
  • 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
Students learn a simple technique for quantifying the amount of photosynthesis that occurs in a given period of time, using a common water plant (Elodea). They… 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.
  • 5-LS1-1. Support an argument that plants get the materials they need for growth chiefly from air and water.

Lesson Plan Grade: 5th-8th
What helps SCUBA divers, sharks, fish, and other marine organisms stay in the water column? In this hands-on investigation, students will explore the concepts of buoyancy and mass to create a device to help an action figure stay neutrally buoyant, just like a scuba diver. 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.

Lesson Plan Grade: 6th-8th
In this lesson, students are challenged to design and build a controlled-release tablet, which will be made from different colored bath tablets and a variety of water-soluble plastics. First, they will have to test the properties of each of the different plastic materials. Then their task will be to create a tablet that releases three different colors, each at a pre-determined time after the tablet has been submerged in water. As students design and build their controlled-release tablets, they… 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-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-10th
In this two-day lesson, students will be introduced to several issues related to the social, economic, and environmental impacts of our current food system, including food waste, food deserts, agricultural land use, and the environmental impacts of diet choices. Read more
NGSS Performance Expectations:
  • MS-ESS3-4. Construct an argument supported by evidence for how increases in human population and per-capita consumption of natural resources impact Earth's systems.

Lesson Plan Grade: 6th-11th
Can we use a model to predict the impacts of nutrient pollutants on an aquatic ecosystem? In this activity, students participate in a kinesthetic simulation to illustrate how nutrient pollution from agricultural runoff can lead to a dead zone at the mouth of a drainage basin. Read more

Lesson Plan Grade: 3rd-8th
Many of the misconceptions about our solar system are rooted in the fact that it is large and hard to comprehend. This kinesthetic activity will demonstrate concepts like rotation and orbit, clarify movement and direction, and help students understand why earthlings see different things in the sky. Read more
