8th Grade Science Projects and Experiments
If you are looking for fun science activities to do with your 8th graders, you’ve come to the right place. We’ve outlined several projects that are bound to offer important lessons to your students this month.
- Does yeast metabolism require aeration?
Yeast is used in the production of different food products like bread and alcohol through fermentation. In this experiment, learners will attempt to alter the rate of yeast metabolism by restricting the available air. Glucose will be used as an energy source.
- Aspirin absorption in carbohydrates
Before the painkiller property of aspirin is realized, it has to get into the body’s bloodstream. Learners will demonstrate the uptake speed in the presence of carbohydrates. Furthermore, the results will inform whether you should accompany painkiller medicines with a meal for faster relief.
- Bacteria and toothpaste
There are multiple toothpaste brands on the market. Unfortunately, not all products deliver antibacterial properties and consequently fresh breath. In this trial, learners will trial various brands against a bacterial sample drawn from the teeth of volunteers.
- Do Roots grow in the direction of gravity?
Plant stems generally shoot upward while the roots follow the gravitational pull downward. During this experiment, learners will attempt to show whether this orientation changes when the growing plant is flipped upside down.
- Hydroponics vs. soil growth
Plants traditionally grow in soil. However, as agricultural land is increasingly becoming scarce, plant growth is being shifted to soilless media. This experiment seeks to investigate the efficiency of hydroponic systems against a regular soil medium.
- What happens during your dog’s early months
During this trial, students will evaluate the growth rate of a man’s best friend. The test subject will be a puppy that is only a few months old. Learners will measure the puppy’s weight and other body proportions in subsequent months, such as its body length, size of ears, tail size, and limbs.
- Effect of high temperature on migratory birds
Most migratory animals will switch habitats due to scarcity of food or even excessive predation. Also, some animals will migrate following unfavorable climate conditions like global warming. Migratory birds provide some magnificent sights when they decide to migrate. However, what causes them to up and go? This experiment will investigate the role of high temperature on migratory birds moving habitats.
- Steps to save migratory animals
During unplanned migrations, there are a lot of animals that are at risk of death, especially if they follow unfamiliar routes. To preserve these animals, students should first understand the reasons that cause these animals to move. After that, evaluate traditional routes and their preferred migration spots before recommending conservation efforts.
- Globular clusters
The universe is an immense space with billions of galaxies with immeasurable numbers of stars. A globular cluster contains millions of stars in orbit around a galaxy. In this project, learners will investigate different aspects of globular clusters using data and gain more insight into the world beyond our galaxy.
