Question?Question?

• What changes will we see in our ponds at different time periods? (3 weeks,6 weeks,10-12 weeks)

HypothesesHypotheses

Rachel• 3 weeks more bacteria

and bugs would start.• 6 weeks bugs , bacteria,

and organisms will become more seen.

• 10-12 weeks bugs, bacteria, mold and organisms are present.

Tess• 3 weeks – life grows,

water will be clearer, Lemna grows.

• 6 weeks – even more life, less soil, Lemna grows.

• 12 weeks – a whole lot more life, leaves will die, hay will die, clearer water, and Lemna grows.

ConclusionConclusion

Tess- I think that I was half right. The hay and leaves did die. There was less soil and more life. However, the Lemna did not grow and the water did not clear up much.

Rachel-I also think I was half right. Bacteria did become more present and so did organism. Bugs and mold did not present themselves however.

Compare & ContrastCompare & Contrast

Similarities • Our ponds contain

bacteria and so do real ponds.

• Lemma is present in both.

Differences • The larger ponds

have more, bigger, and different animals than our ponds.

• The larger ponds experience climate changes and different types of weather.
