Bowl Of Life Biology Science Experiment
In this fun and easy biology science experiment, we’re going to create a bowl of life to explore and investigate the life cycle of a mealworm.
- About 100 mealworms (you can get these at the pet store)
- A plastic container with a lid
- Baby carrots
- Dry and uncooked oatmeal
- Carefully poke several small air holes in the lid of your plastic container.
- Now, add a layer of oatmeal in the container. This will be food for the mealworms.
- Next, add a couple carrots. This will provide water for the mealworms.
- Add your mealworms to their new habitat. The mealworms do not bite so feel free to handle them gently. Remove any dead mealworms and secure the lid.
- Observe the mealworms daily and document any changes you may notice.
- After about ten days, you should start seeing some significant changes.
- We will not spoil the surprise, but watch your habitat for a few more days and wait for transformation to be complete!
- If you would like the life cycle to continue, add a bit of fresh oatmeal and a few new carrots to your habitat and observe if any unseen eggs hatch over time.
How it Works:
The mealworm is the actually the larva of a Darkling Beetle. The life cycle of the Darkling Beetle begins with an egg, then larva (mealworm), pupa, and then adult (Darkling Beetle). By providing a perfect habitat for the mealworms, they have the opportunity to develop into adult Darkling Beetles.
Make This A Science Project:
Try this experiment with superworms. Place your mealworms on a paper plate. Put different foods at different locations of the plate and observe if the mealworms show a preference. You could try sugar, carrots, fruit, etc. You could also place your mealworms on a surface that one side is wet and one side is dry to see in the mealworms show a preference.
