I have done everything else for this blog submission except for my method. So, here it is :) Enjoy!!
Aim: To investigate whether the addition of sugar when watering a seed effects the speed of growth of the plant.
Hypothesis: The plant with the most sugar will grow the fastest.
Equipment and Materials: 4 polystyrene cups, a permanent marker, 8 pea seeds, cotton wool balls, sugar, water, measuring cup, ruler and sunlight.
Method: 1. The polystyrene cups were labelled using the permanent marker. One was labelled "normal", the next "10%", the third "25%" and the last "50%".
2. The 4 polystyrene cups were each filled to about halfway with cotton wool balls.
3. 2 pea seeds were placed in each cup, just on top of the cotton.
4. Using the measuring cup, 40mL of water was measured.
5. The water was poured into the cup labelled "normal".
6. Step 4 was repeated.
7. 4 grams of sugar was mixed with the 40mL of water.
8. This solution was poured into the cup labelled 10%.
9. Step 4 was repeated.
10. 10 grams of sugar was combined with the 40mL of water.
11. The solution was poured into the cup labelled "25%".
12. Step 4 was repeated.
13. 20 grams of sugar was mixed with the 40mL of water.
14. This solution was poured into the cup labelled "50%"
15. The 4 cups were then placed in an area which received alot of sunlight.
16. A photograph of the experiment was taken.
17. Steps 16 was repeated every 3 days for 2 weeks, observing and taking note of the difference in the growth of the seeds.
18. The results were recorded in a table, stating how many days the seeds took to grow (days) and whether or not they grew at all.
Thats it :) i wasn't sure whether or not to get our a ruler and measure the seeds, or just note the effects the sugar has on the plant. But as you can see, i decided to go with the ruler. If there are any problems, im sure ill be able to make slight changes. Also, ive based the hypothesis on the fact that sugar makes a person more "hyper" and their brain and body to work faster. Hopefully it will have the same effect on a plant.
