Explanation:
Conducting a Life Science Project
Life sciences involve the studies of the human body, Earth's structure, and the different organisms that populate the planet. In case you need to review any areas of science to prepare yourself for the project, Study.com's Life Science course has all the resources you need, from video lessons to quizzes and tests.
DIY Bird Feeder
This one can be done at home or outside of your classroom. Using an empty half-gallon milk container, cut out a square-shaped hole in the middle of three sides of the carton. You can fill this up with seed, and use string to hang the carton from a nearby branch. Before you know it, all kinds of different birds will be enjoying the buffet. Record your data about what kinds of birds are sharing the feed, and the different chirps that come along with the birds.
Bacterial Growth
Although we can't see them, bacteria exist everywhere, even on the mouse and keyboard you are using to browse this article. With several petri dishes, use cotton swabs around your home on different areas that are frequently touched: faucet handles, door knobs, remotes, video game controllers and the like. Spread the swab on the nutrient gel located inside each petri dish, and after labeling them, you can observe their growth patterns over the next week. Which bacteria are growing the most, and where were they located? How many different people had been using the objects you swabbed?
Blind Taste Test
You've probably heard that the senses of smell and taste are intertwined, but this project will prove it for everyone involved. Using cotton swabs, have your blindfolded friend test the tastes of different sauces and attempt to classify them. When they have run through all of the selections, shuffle the sauce order and do the test once more while your friend holds their nose. How many did they get correct, and did the number change when they could not smell them?
Tracking Water Through Plants
Fill a cup of water and mix a few drops of blue food coloring before dropping a carrot into the cup. Come back after a few hours and slice off a section near the tip. You'll notice a distinct color pattern circulating through the roots of the plant. How does this demonstrate the movement of water? Cut another section off and see if the pattern remains the same.
