Results

• The Elodea did not take in the CO2 in the dark.

Prediction

• The snail will give off CO2 and the BTB will turn
  yellow and the elodea will turn the BTB back to
  blue.

Interpretation
Day 1

• Day1 The snail gave off Co2 in the dark than it
  turned the BTB to yellow
• Day2 The Elodea Did not take in the Co2 in the
  dark and the BTB remained yellow.

Day 2

Conclusion

• Our hypothesis is that the elodea will use Co2
  that the snail gives off in the dark. But when we
  did the experiment the Snail did give Co2 in the
  dark. But the Elodea DID NOT use the Co2 in the
  dark.
