Botany Science Projects

Science projects for all grades.

Starting a Science Project

What Makes A Good Science Project?

Some advice from a science fair judge

The Parts of a Science Project

The idea behind a science project is to discover "what happens if." What happens to one thing if you change something else?

Science Fair Projects: Understanding and Using the Scientific Method

The scientific method is extremely important to your science fair project, and understanding it is critical to the success of your science fair experiment.

Botany Science Projects For Beginners

In Which Liquids Do Seeds Grow Best?

Find out which liquids are best for sprouting seeds

Germination
Hydroponics

Does Microwave Radiation Affect Seed Growth?

Do seeds that have been exposed to microwave radiation grow as well, or better, than seeds that haven't been micorwaved

Microwave Oven
Microwaves

Which Bulbs Are Best for Forcing?

Force tulips, daffodils, crocuses, lilies, hyacinths, and other bulbs to grow inside and see which grow the best

For reference: Bulbs, Tulips

Botany Science Projects For Intermediate Levels

Does the pH of Water Affect the Growth of Bean Plants?

Does the pH of the water with which plants are sprinkled affects the rate of growth.

For reference: Acids and Bases, pH, The pH Scale

Creating New Plants Through Cross-Pollination

Find out what happens when you cross-pollinate—or remove pollen from one type of flower and put it onto another type.

For reference: Genetics, Pollination

Do Bean Plants Grow Better in Soil or in Water?

Hydroponics is the practice of growing plants in water instead of soil. Test whether bean plants grow better in soil or in water.

For reference: Germination, Hydroponics

Botany Science Projects For Advanced Levels

Can Cloning Make a Better Plant?

Use a method of vegetative reproduction (stem cuttings) to clone plants from a parent plant to test if a plant you clone from another plant is better than the original.

For reference: Clone, Hybrid, Pollination, Budding, Cutting, Grafting, Runner

How Close to a Plant Must Pesticides Be in Order to Be Beneficial?

A pesticide is anything that destroys pests or suppresses or alters their life cycles. Experiment to see how close to a plant a pesticide must be in order for it to be effective.

For reference: Pesticides

Can Healthy Plants Be Grown in Soil Containing No Microorganisms?

Microorganisms can be both good news and bad news for plants and those who grow them. Investigate whether plants grow better in soil containing microorganisms than in soil that has none.

For reference: Algae, Bacteria, Fungi
