Experimental Design First draft

Last night I completely finished my experimental design first draft. So this morning I put my first draft up on turnitin.com. 

Experimental Design

Purpose: What is the affect of acid rain on the photosynthesis rate of primroses?

Hypothesis: If you water the primrose with acid then it will slow down the oxygen production of the primrose.

Materials:

1. 6 Primroses

2. Acid rain

3. 6 Plastic containers

4. Oxygen probe

5. 2 Syringes

6. 6 stopper

7. Plain water

8. Goggles

9. Apron

Independent Variables:

The ph level of the acid rain

Dependent Variable:

The oxygen production of the primrose

Procedure:

1. Remove the flowers off of three of the primroses

2. Put the primroses with flowers in three separate plastic container

3. Put the primroses with no flowers in three separate containers

4. Tape every container shut and stick the stoppers in the hole

5. Put 100 ml of plain water into the syringe

6. Quickly take the stopper out the container with the primrose without flowers

7. Stick the syringe into the hole in the container

8. Squeeze out the water into the soil of the primrose

9. Quickly take the syringe out the container, and then put the stopper back in it

10. Put 100 ml of water into the same syringe

11. Quickly take the stopper out the container with the primroses with flowers

12. Stick the syringe in the hole in the container

13. Squeeze the water out into the soil of the primrose

14. Take the syringe out and put the stopper back in the container

15. Take one of the containers with a primrose with no flowers

16. Put 100 ml of acid rain with a pH of 4 in a different syringe

17. Quickly take the stopper out the container

18. Squeeze the acid rain into the soil of the primrose

19. Take the syringe out of the container and put the stopper back in

20. Get the container of primroses with flowers

21. Put 100 ml of acid rain with a pH of 4 in a different syringe

22. Take the stopper out the container

23. Squeeze the acid rain out into the soil of the primrose

24. Quickly take the syringe out of the container and put the stopper back in

25. Repeat steps 15-24 exactly but water the primroses with acid rain that has a pH of 3 instead of 4

26. Take a picture of the setup

27. After 24 hours test the oxygen production using a oxygen probe

28. Stick the oxygen probe into the hole in the container

29. Remove the oxygen probe from the container after it collects the data

30. Stick the oxygen probe into the computer and open data studio

31. Repeat everyday for 2 weeks
