If you wish to add a fun element to learning, interesting experiments are an excellent choice! Read on for some biology experiment ideas.
Science, the effort to discover how the physical world works, can best be understood through experiments. Experimentation is, in fact an excellent way to comprehend any new subject. It is the means to demonstrate natural processes in order to gain an understanding of their occurrence.
Biology is one of the different branches of science, which deals with the scientific study of living beings. Here we give you some interesting and easy ideas for biology experiments.

Biology Experiments

Experiment 1: Photosynthesis

As you know, plants need sunlight for growth. Photosynthesis, one of the vital processes occurring in plants, needs sunlight.
This phenomenon can be demonstrated through a simple experiment. All you need for this experiment is a pair of potted plants. Place one of the plants near the window of your classroom, so that it gets enough sunlight throughout the day.
Place the other potted plant away from the source of light and see the difference. Interestingly, you will notice that the plant which was kept away from the window has turned towards sunlight. This is known as phototropism. This observation is sufficient to explain the importance of sunlight for plants. Isn't it?

Experiment 2: Germination of Seeds

Have you seen how seeds germinate? I am sure you would like to, in case you haven't. For this experiment you will need some seeds. Take a bowl full of beans or peas and get ready to see them sprout!
Soak the seeds in water and then place them in moist soil.  With passing time, you will see them germinate and gradually grow into shoots. Being easy and needing less apparatus, kids can conduct this experiment without adult supervision. On that note, you may like to go through other such simple biology experiments for kids.

Experiment 3: Blood Group Detection

Have you ever thought of being able to detect blood group compatibility through an easy experiment?
You will need a well-equipped laboratory for this experiment and it is advisable to perform it under the supervision of your biology teacher. Collect samples of blood belonging to different blood groups. Work on one sample at a time.
Mix the sample with different reagents containing one of the three antibodies, namely, A, B or Rh. If blood agglutinates in a certain mixture, it means that the blood has reacted with the antibodies contained in that mixture and is not compatible with blood containing that antibody.

Experiment 4: Vermicomposting

Vermicomposting is known as being a very complex process that is often carried out on a large scale.
But it can be demonstrated on a smaller scale. It turns out to be an interesting experiment that tells you why earthworms are known as farmers' friends! For this experiment, you will need a can/bin made of plastic, wood, or metal with a removable lid. See that it has holes in the sides to enable flow of air.
You will need to maintain a temperature within a range of 12 and 21 degrees Celsius in the bin. Prepare a bedding of soil, dried leaves, and kitchen waste to provide the worms with their natural habitat. Observe the behavior of the earthworms in this controlled environment
They turn the layers of soil upside down, thus increasing the aeration in soil. Their excreta increase the nitrogen content of soil and also its fertility.
These were some experiments that can make biology interesting. You can come up with many such biology experiment ideas, if you are a keen observer of nature. It is our natural environment which provides us with the 'apparatus' to 'experiment'!
