If you're looking for fun biology experiments to do with your kids, you'll enjoy this assortment of suggestions. Encourage your child's interest in conducting biology research through these interactive activities.
Designate a segment of your garden as experimental. Have your children research online what soil conditions work best for the crops you plan on planting. Bring a soil sample to the local nursery or home improvement store and have them check the soil for your child. Let your child do research online to learn what changes can be made to the soil in order to give the crops the optimal advantage. Plant seeds both in the control section of the garden-your section-and in the experimental section-the beefed-up soil your children have prepared. Give the plants the same amounts of water, fertilizer and attention. Measure plant growth and crop production. Encourage your children to keep charts comparing the results.
Conservation Biology Experiment
This field biology experiment literally takes place in a field. Borrow a pair of binoculars and a bird-watching book from the library. Hike out to a local field and bird watch with your children, recording the number and types of birds you see over the course of an hour. When you return home, have your children search online to discover the ecological impact of each of the birds you sighted. Did you see birds that eat bugs that are considered pests by local farmers? Identify one species of bird that is a positive influence on the local ecosystem and brainstorm ways to support the existence of this species in your area.
Help your kids do the research necessary to determine if adding a type of birdhouse, food source or water source might help this bird survive. Work with your kids to provide one of these resources, such as a bird feeder stocked with this bird's favorite food, or birdhouses favored by the species. Take time once a month to send your kids out bird-watching, searching for an increase in the number of birds of this species. Discuss ways individuals in a community can work to improve an ecological environment.
Freshwater Biology Experiment
Take your kids to a local stream, pond or lake. Bring along several buckets, clear jars and nets. Before you go, have your students read up on the local area, listing out the possible forms of life you might find near your home. Spend time in the water, scooping up water, mud and silt. Let the water and mud settle in the clear jars, then list off any living things you find. Take pictures of creatures you cannot easily identify; when you get back home, look them up on the Internet.
Take samples from different parts of the stream, pond or lake and record your various findings. Make sure you let any captured creatures go before you end your field trip. If you've got a microscope at home, take a small amount of water home with you and see if you can identify any microscopic creatures on a slide. Return to the site during a different part of the year to see if the seasons affect the number or kinds of life you find.
Is your child wondering how is biology used in everyday life? Offer these practical examples of the daily benefits we get from studying biology.
Is your child asking, "What is natural selection?" Learn how to explain Darwin's theories of survival of the fittest and adaptablity in living things.
Is your child asking, "What are genes?" Learn how to explain what they are and how they help make each person unique.
