Pond or Lake?

Pond or Lake?

• Rachel Rice
• Tess Vessels

2
Overview Description

• We learned about the life in our ponds.
• We observed our ponds with and without
  microscopes.
• We drew our observations at different time
  periods.
• Tess- I learned about the interesting things
  seen in our ponds.
• Rachel- I learned about different organisms that
  live in our ponds.

Question?

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

4
Hypotheses

• 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.

Conclusion

• 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 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.
