Biology Science Fair Projects ListBiology

Biology is the science of living organisms, including botany (plants), zoology, and human beings. Biology involves the examination of structure, growth, function and the evolution of life.

All projects

  • Ant Microphotography

    To prepare an ant so that its brain and nervous system may be photographed through a microscope. You will then take photographs of the ant using a digital camera for documentation.


  • Barney Banana

    A fun expiriment to demonstrate how to slice a banana from inside, before peeling it.


  • Colorful Celery

    To create stalks of colorful celery while demonstrating how plants need and draw water to survive.


  • Cultivate Slime Molds

    To cultivate a living slime mold and observe the stages in which a slime mold forms.


  • Dehydrated Potato

    To demonstrate the process of dehydration


  • Double Color Flower

    To create a double color flower


  • Gravity and Plants

    NASA has long studied the effects of gravity on plants by taking plants with them during space expeditions and onto space stations. You can find out for yourself how plants grow in low gravity conditions by conducting this simple experiment.


  • Growing Bread Mold

    To demonstrate that bread mold spores are present anywhere and everywhere


  • Lemon Floaties

    To determine whether a lemon will float in water or sink to the bottom.


  • Magic Balloons

    To demonstrate how the gases from yeast can be used to blow up a balloon.


  • Mini Greenhouse

    To create a miniature greenhouse to grow living plants.


  • Molls Experiment

    To demonstrate that plants cannot manufacture its food (photosynthesize) unless carbon dioxide molecules are available.


  • Nocturnal Plants

    To demonstrate that plants need sunlight in order to survive.


  • Preserve Spider Webs

    To collect spider webs and preserve them for demonstration.


  • Spore Prints

    To record the spore prints left behind by mushrooms.


  • Stem-less Flowers

    To demonstrate the importance of plants stems for the purpose of their survival.
