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: Is this an acceptable Science fair experiment?

Is this too easy of an experiment for a 6th grader in an advanced class.

1. What Foods do dogs react to?
2.How long does it take for them to notice each food?
3.Why are they attracted to only some foods?

For question 3 would I just look the ingredients up or is there something else I need to do

What grade would I probably get

Please answer all of the questions

Answer: what grade u would get probably depends on ur teacher. for question 3, u should look up ingredients and try to find the ingredients that are common among the foods that dogs react to.

if u want a science fair project that is very cool and more advanced, you should do electroplating (u can look it up on google). that was my science fair project when i was in 6th grade and i got 1st place. it isn’t too hard, and it is more impressive than different dog foods. just e-mail me if u have any questions about it
