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
Forests are the green lung of the Earth and home to millions of different plant, fungi, animal, and bacteria species. Unfortunately, today many forests are threatened by deforestation, which causes significant biodiversity loss. Ongoing reforestation efforts across the world intend to counteract the effects of deforestation. As planting trees by hand does not scale well, machines on the ground, as well as flying drones have been developed to help plant tree seedlings or seeds. In this lesson,… Read more

  • MS-ETS1-2. Evaluate competing design solutions using a systematic process to determine how well they meet the criteria and constraints of a problem.
  • MS-ESS3-5. Ask questions to clarify evidence of the factors that have caused the rise in global temperatures over the past century.

Lesson Plan Grade: 5th-9th
Could you describe the kelp forest food web as a system? Your students will design and use a simple model to test cause and effect relationships or interactions concerning the functioning of a marine food web, ranking their hypothetical ecosystems according to their stability when faced with a natural or man-made disturbance.

NGSS Performance Expectations:
  • 5-LS2-1. Develop a model to describe the movement of matter among plants, animals, decomposers, and the environment.
  • MS-LS2-3. Develop a model to describe the cycling of matter and flow of energy among living and nonliving parts of an ecosystem.
  • MS-LS2-4. Construct an argument supported by empirical evidence that changes to physical or biological components of an ecosystem affect populations.
  • HS-LS2-6. Evaluate the claims, evidence, and reasoning that the complex interactions in ecosystems maintain relatively consistent numbers and types of organisms in stable conditions, but changing conditions may result in a new ecosystem.

Lesson Plan Grade: 6th-8th
If your doctor prescribes antibiotics, why do you have to take them for several days and not just once? Why do you need to finish taking them even if you feel better? If you do not follow the doctor's orders, you might contribute to the creation of antibiotic-resistant "superbugs"! In this lesson, your students will roll dice to model how bacteria respond to treatment by antibiotics, and find out what happens if treatment is stopped too early. Read more
NGSS Performance Expectations:
  • MS-LS4-4. Construct an explanation based on evidence that describes how genetic variations of traits in a population increase some individuals' probability of surviving and reproducing in a specific environment.
  • MS-LS4-6. Use mathematical representations to support explanations of how natural selection may lead to increases and decreases of specific traits in populations over time.

This activity demonstrates how potential energy (PE) can be converted to kinetic energy (KE) and back again. Given a pendulum height, students calculate and predict… 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.
  • MS-PS3-2. Develop a model to describe that when the arrangement of objects interacting at a distance changes, different amounts of potential energy are stored in the system.

Lesson Plan Grade: 6th-8th
Students explore adaptations by researching how animals, plants, and bacteria change based on their environment. They grow bacterial colonies in various environments and hypothesize how each environment will affect the cell culture size and color. After a day of pre-growth, the culture is spun down in a centrifuge and the cell pellet is analyzed. Finally, students research bacteria adaptations that allow them to survive in extreme environments then brainstorm how the beneficial… 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
Do you feel like it is always too loud in your classroom? In this lesson you can find out exactly how loud it is. Using Google's Science Journal, your students will measure and graph the sound levels in your classroom for different working scenarios. How loud are your students when doing independent work, having a group discussion, or listening to their teacher? Based on your students' data, you will determine as a class which sound levels are ideal for each scenario and create a classroom… Read more
NGSS Performance Expectations:
  • MS-PS4-1. Use mathematical representations to describe a simple model for waves that includes how the amplitude of a wave is related to the energy in a wave.

Do sea levels rise when ice melts? Does it matter whether the ice is on land or in the ocean? Students design an experiment to find out. They collect data, graph their results, and interpret their findings. Along the way, they learn about density, displacement, and climate change. Read more
NGSS Performance Expectations:
  • 5-PS1-2. Measure and graph quantities to provide evidence that regardless of the type of change that occurs when heating, cooling, or mixing substances, the total weight of matter is conserved.
  • MS-PS1-5. Develop and use a model to describe how the total number of atoms does not change in a chemical reaction and thus mass is conserved.

Lesson Plan Grade: 6th-8th
Teach your students about the engineering design process with this fun lesson plan. They will design and build a ball-launching machine to knock down a target. Optionally, they can enter their designs in the 2020 Fluor Engineering Challenge for a chance to win a cash prize for your school! Teachers, note that elementary school and high school versions of this lesson plan are also available, as is a Spanish language version of the basic challenge. 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.
  • 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 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.
