What's in Your Water?
by Jesus D.
3rd Grade, Room 10 - 3rd Place

Question: What's in your water? Can different types of water make seeds grow? Does tap water have bacteria?

Hypothesis: I think that the ocean water 1 and 2, and toilet water, will be positive for bacteria. I also think taht all other ones may be negative for bacteria, although I think Apollo Lake water may be positive or negative. I also thought Apollo Lake would grow the most seeds and tap water the least.

Procedure: To proceed, I sampled many water sources. Then I put seeds in each for 3 days. While those were testing, I tested pH and alkalinity and bacteria levels in the water.
