Biology Science Projects For Beginners

Which Foods Do Molds Love Best?
Figure out on what kinds of foods, and under what conditions, molds grow best. Do they prefer light or darkness, wet foods or dry foods, and heat or cold?
For reference: Mold, Slime Mold, Fungal Infections
What Foods Attract Ants?
Ants have a chemical sensory aid that directs them to the foods they love the most. Experiment to determine which foods from your kitchen ants like best.
For reference: Ants, Fats, Carbohydrates, Protein
Do Loud Noises Affect Heart Rate?
Reflexes are sort of an automatic safety response system in your body, and they work to protect you from harmful situations. Try to find out whether loud noises affect the rate at which a person's heart beats.
For reference: The Nervous System and Reflexes, Pulse, Heart

Biology Science Projects For Intermediate Levels
