High School Biology Experiments

High school bio experiments don't need to be hard!

Are you looking to learn about high school biology experiments? In many high schools, teenagers are required to take biology at one point or another. Experiments are a common part of biology courses, whether they be a part of a controlled laboratory class, science fair or a part of individual student projects. Unlike science in middle school, high school biology is hands on. Keep reading to learn about a few high school biology experiments you might be interested in performing all in the sake of science.

Scientific Method and HS Biology

Much of high school biology is focused on instilling the elements of science on students. The scientific method is one of these main focuses. The method prompts participants in science to be investigators and to come up with a guess about what will happen in a given experiment, called a hypothesis. The point of the experiment is then to either prove the hypothesis correct through the experiment or prove it incorrect. This prompts teens to get involved in the scientific method while teaching other scientific skills such as:

  • The ability to make a rational estimate based on present factors and knowledge
  • Close detail and monitoring skills
  • The possibility of being wrong and how to move past that if it turns out to be the case
  • Quick thinking skills

As much fun as biology experiments can be, there is an educational component spearheading the experiment.

Examples of High School Biology Experiments

Whether you are looking for a science fair project or need to create a project for a class assignment, there are numerous biology projects for teens to get their hands in.

  • Animal regeneration: Many animals can regenerate. A good experiment may include cutting an earthworm, a hydra, planarian, and other like organisms in half and seeing if any of them can regenerate themselves.
  • The effect of light on growth: In this experiment, students can monitor how different types of light affect plant growth. A student will start with three plants of the same type (flowering plants generally work best) planted in similar soil and holders. One can be placed in an area of high sunlight exposure, another in an area of medium light exposure and another in an area with little exposure to the sun. Over the period of a week or two, teens can monitor how each plant grows.
  • Oxygen and candles: A simple experiment using different sized jars can show how a candle uses oxygen. Place a candle that is lit in a jar and close it. Monitor what happens to the candle. Place another lit candle in a larger jar and monitor what happens to it. Teens can easily see the effect of larger amounts of oxygen on the candle.
  • Diversity among plant samples: Another simple biology experiments involves going into your natural environment, such as a local park, to observe diversity among plant samples. To make the experiment more detailed, students can rub collected samples on filter paper to observe which plants present which colors. Teens can work to find out why certain plants present certain colors.
  • Water from common sources: Water is everywhere. Unfortunately, water contains numerous elements too. A great experiment is collecting water samples from a wide variety of sources and viewing them under a microscope. Students can then compare their results and attempt to postulate why a given water source would present more organisms than another would.
  • Growing cultures: Bacteria is everywhere. Another science experiment teens can do is to swap different sources (such as the inside of your mouth or an air conditioner filter) on the plates of agar and incubate their growth. Viewing how each swapping grows can help teens create conclusions about their source.
  • Yeast: Another experiment involves taking a piece of bread to monitor the molds that grow over a period of two weeks.

More Places To Find Experiments

There are numerous places to find biology experiments both simpler and more advanced than those listed above. Some of these places include:

Final Thought

For teens, high school biology can be fun. Finding the right experiment can help biology pop off the page and become more than just another required course of study.
