Question: Is space food supplemented with food grown hydroponically on the I.S.S.?

Or are the only plants grown up there just part of life sciences experiments?
By space food i mean astronaut rations.

Answer: The ISS does have a greenhouse garden called Lada. They grow peas and mizuna (and are studying how plants grow in microgravity – essential for trips to Mars and such), though the crops produced are only in small amounts. Their main diet is still pantry-style and reconstituted (tho (needless to say) much better than that astro-pack junk we buy at the gift shops). They are going to try some grains and barley next.

As a side note … they also found that the gardening has a psychological effect and when Columbia broke up – the crew on the ISS was assigned extra garden time to help calm them.

Question: What are some Science Experiments/projects/report that I can do in 1-4 days?

and that will get me good-average mark thanks

Answer: Build a homemade solar cell. The only supplies you need are a stovetop, two sheets of copper flashing from the hardware store (should cost about 4 dollars a piece for shingles), a soda bottle, salt water, two aligator clip leads, (at the hardware store for less than a buck), and (optional) a amplitude meter to read how much power you are generating. There is a procedure on how to do this online and it is very simple, I did it in about 3 hours and it is really cool. Heres the link for the procedure, http://worldwatts.com/homemade_solar_cell/homemade_solar_cell.html BTW, im not spamming for the site because I have no relation to it. Try this project its fun and has a cool result, because if you tell your teacher that you are interested in making alternative energy sources then she will be very pleased.
