Unit 1: Photosynthesis and the carbon cycle
Ask students to write down their name to the science report.
Getting started:
● Teacher guides student how to set up the apparatus.
6
●
Teacher explains water plants giving off bubbles which is evidence that
plants release oxygen gas.
●
Teacher models the steps for the students and point out some notes while
doing experiment and how to draw a results chart.
●
TA record the process while teacher is doing the experiment
●
Teacher ask students to work in group of 4 and complete the report
(except for results).
● Ask student to follow the procedures after finishing the report.
Procedures :
1. Set up your apparatus. Place the lamp close to the test tube. Leave the
apparutus like that for about 5 minutes, to give the plant time to settle
down and start to photosynthesise.
While you are waiting, read the rest of these instructions and then draw a
results chart.
When you can see bubbles coming from the cut end of the plant stem, you
can start your experiment.
2. Measure the distance between the lamp and the test tube, and write it
down in your results.
3. Start the timer. Count how many bubbles the plant produces in one
minute, and write this down.
4. Repeat step 3 two more times.
5. Now move the lamp a little bit further away from the test tube. Measure
the new distance.
6. Repeats steps 3 and 4.
7. Repeat steps 5 and 6 for at least two more distances of the lamp, further
from the test tube.
Report :
 Teacher ask the students to complete the rest of the report and submit
before the lesson ends.
 Student 's reports will be evaluated based on the scheme attached
