Photosynthesis Science Fair Projects and Experiments
Sugars created in photosynthesis can be later converted by the plant to starch for storage, or it can be combined with other sugar molecules to form specialized carbohydrates such as , or it can be combined with other nutrients such as nitrogen, phosphorus, and sulfur, to build complex molecules such as and .

All of the sugar produced in the photosynthetic cells of plants and other organisms is derived from the initial chemical combining of carbon dioxide and water with sunlight.
A reduction in light penetration affects other aquatic organisms in the habitat, such as phytoplankton and aquatic plants that need light for photosynthesis.

We exhale the carbon dioxide that plants need for photosynthesis.
Many scientists contributed to the discovery and understanding of photosynthesis throughout the ages; in this page are outlined some of those crucial milestone experiments that contributed to this effort.
Jan Baptista van Helmont, Flemish physician, chemist, and physicist, in the 1600s carried out a famous experiment by growing a willow tree in a pot for five years.
Fun science about plants for homeschooled kids
Ponds are among the richest and the most interesting natural environments to observe. Tomake a pond it is sufficient to have a garden or, a meadow or a wood near your home. It isnot necessary to be large, a square meter (9 square feet) of surface is sufficient, buttwo(18 sq. ft.) are better. Find a shady position in the garden. Dig a hole of about 2square meters, 50 cm(2 feet) deep. At least one side, the border has to gently slope downto allow to little animals to enter and leave, for hedgehogs and opossums to drink and tobirds to bath without being too deep. Put some sand in the bottom. Leave the grass on theside. Bare roots are okay. Waterproof the hole with a tarpaulin of white PVC. Why white?Because you can see aquatic animals better when they come near the shore. Cover the borderof the tarpaulin with the grass sod. Allow the tarpaulin to extend for at least 40 cm (16inches) beyond the sloping shore. In this position you can keep the water in such a way tocreate the typical conditions of a marsh. Fill up the pond with tap water and shovel somesand or soil in the bottom: they will benefit the aquatic plants. Go to a natural pond ormarsh and collect some aquatic plants. If it is possible, carry some gallons of water fromthe pond and pour them into your puddle, which will be enriched with microorganisms,algae, and animals, which live in ponds. In few days, your little pond will become greenwith algae and very rich of protozoa. Rapidly dragonflies will come to lay eggs, boatflies, coleoptera and aquatic spiders also will come. In the spring, frogs and newtswill come to lay eggs. The observation of the life in a pond is fascinating. You canremain for hours watching the organisms, which live in this ecosystem. Buy books torecognize the organisms that live in the ponds. See bibliography (5, 6). These texts willalso give you also useful information on the habits of these plants and animals. For anexercise, note your observations in a book, glue pictures, and sketch drawings. Everyyear, during the fall, you should clear out the pond. Shovel out the stinking mud, washthe tarpaulin, or changed it if it leaks, put some tap water, winter rain will supply theremaining part. In spite of what shopkeepers will tell you, your pond does not need pumpsto circulate water, nor aerators, nor falls, nor fountains, nor anything else. The pond isbetter to be as natural as possible. Little ponds of private gardens are very important toamphibians. Avoid introducing fish. They will eat the eggs of the amphibians and thetadpoles. Moreover, the newts will keep the pond free from the mosquito larvae. When thereare tadpoles, your pond will be visited by water snakes, with difficulty you will noticeof them!... and --- don't be frightened: they are harmless!
