New Things We’ve Learned:

Plants in the Light vs. Dark: 1. Draw and Label how we are setting up our mini-experiment:

2. What do you predict is going to happen to the BTB in each solution, after 24hours:

Set-Up What was the BTB like at the start?

What will happen to the BTB?

Why do you think this?

BTB in Distilled Water

BTB in Soda Water

BTB in Algae Cup (in the Light for 24hrs)

BTB in Algae Cup (in the Dark for 24hrs)

3. What happened to the BTB in each set-up after 24hours?

Set-Up What was the BTB like at the start?

What happened to the BTB?

Why does this tell us?

BTB in Distilled Water

BTB in Soda Water

BTB in Algae & Soda Cup (in the Light for 24hrs)

BTB in Algae & Soda Cup (in the Dark for 24hrs)

4. Plants do a process called PHOTOSYNTHESIS in the light.

What do plants need / take in, in order to complete Photosynthesis?

What evidence do we have to support our answers?

5. Do plants do PHOTOSYNTHESIS in the dark? ______________

What evidence do we have to support this answer?

Snail & Elodea A biology class (that has more money than Ms. Rozema’s)

conducts an experiment with plants and animals. They learned a lil

bit about cellular respiration and animals, and were learning more

about photosynthesis and plants. But, to better understand both

processes, and how they connect, they wanted to run an experiment

with animals living amongst plants.

So…. This rich biology class buys some aquatic snails, and some

elodea (an aquatic plant). The fill some large test tubes with distilled

water, BTB, and then a mixture of just plants-just snails-snails and

plants. They then put some of them in the light, and some in the dark.

The following are the results of this experiment.

Part 4: Making Predictions For each of the following set-ups, FIRST PREDICT what you think will happen (based on previous

simulations), and then PRESS PLAY and record the ACTUAL RESULTS.

PUT IN THE TUBE Prediction Why Do You Think This?

lights on

How will the color change?

Which gas will be higher?
