Science projects are a hands-on way to learn about a particular topic. Many science projects take at least two weeks to complete, so proper preparation is essential to getting the project completed in time for presentation. Tracking your project daily will leave you with consistent and accurate results you will then be able to present once the project has been completed.
Does Sunlight Affect A Plant's Growth?
Select two plants of the same variety, allowing one specimen to grow in natural sunlight, and the other to grow in the dark. Label the plant in sunlight "Light" and the plant in the dark "Dark." Cut open one side of a box large enough to cover the dark plant, then place the box on top of the plant so no sunlight will touch the plant. For the next two weeks, keep a record of the growth of each plant by measuring the height of both plants daily. Water both plants equally. Record your hypothesis at the beginning of the project, then record your findings after the two-week growth period finishes.
Choose a piece of fruit and a vegetable of your choice, along with one slice of bread. Place each specimen on a plate, and store it in a spot where the specimens will not be disturbed by animals or humans for two weeks. Record the appearance of each object daily, noting when each item begins to develop mold. Record your hypothesis at the start of the project, and the end results after the two-week period finishes.
Purchase three or four different types of beans in a raw, unprocessed variety, or beans intended to be used in gardening. Use only beans that are undamaged and uniform. Poke holes into a paper plate, then set a moistened paper towel on top of the plate. Lay the three or four beans on top of the paper towel, and sprinkle the beans with a small amount of water. Place a second moistened towel on top of the beans, and place the entire project into a zip-lock baggie. Put the project in a darkened cupboard or box, and water daily. Record growth of sprouts every day for two weeks.
Does Saltwater Affect Plants?
Choose two plants of the same variety, and label one "Salt" and "No Salt." Set both plants in direct sunlight, and record the starting height of each plant. Water both plants the same amount daily, except water the plant labeled "Salt" with a saltwater mixture; 1 Tbsp salt to 1/4 cup of water. Record the height and appearance of both plants over the next two weeks. Record your hypothesis before beginning the project, and the end result after the two-week time period finishes.
