Title:

Results of Growing Sugar Snap Peas with Different Liquids

Question:

What would happen if we soak a seed in vinegar for 2 weeks and do the same with water and food coloring mixed with water?

 

 

Hypotheses:

The seed put in food coloring mixed with water will be a dark color, the seed put in vinegar will be bubbly, and the seed put in water will stay the same.

Materials:

We used water, vinegar, food coloring, 3 seeds, and 3 containers. The water, vinegar, and food dye were the different liquids mentioned in the title.

 Procedure:

We put the seed in vinegar, and did the same with the water and food coloring mixed with water. Then we waited for 2 weeks. We looked at the color, texture, changes, and growth in the seeds after 2 weeks.

Data:

 Seed 1 was placed in 1½ cups of water on 12/6/11 and taken out on 12/19/11 (2 weeks)

Seed 2 was placed in 1½ cups of vinegar on 12/6/11 and taken out on 12/19/11 (2 weeks)

 Seed 3 was placed in 1½ cups of water mixed with more than 20 drops of food dye on 12/6/11 and taken out on 12/19/11 (2 weeks)

Below are our observations.

Label	Growth	Texture	Color	Changes	Seeds
1	1.1 cm	Smooth	Tan	Way Bigger Than Beginning	Water
2	.9 cm	Wrinkly	Light Tan	A little Bigger	Vinegar
3	1.1 cm	Smooth	Dark Purple	Bigger	Food Coloring

 

Results:

I found that the seed in water got bigger than the seeds in food dye and vinegar. The sizes of the seeds from smallest to largest after the experiment were: vinegar, food dye, water. I also found that the seed in food coloring did change color, the seed in vinegar did get bubbly and got lighter in color, and the seed in water did not stay the same; it got bigger, but stayed the same color.

Conclusion:

I noticed that the seed in food dye mixed with water turned purple and grew a little bigger, the seed in water grew a lot, and the seed in vinegar grew very little.

Something that may have caused the seed in vinegar to shrivel may have been that it had more
acid.

What went as planned was that the seed in water grew big, the seed in vinegar didn’t grow much, and the seed in food dye mixed with water turned purple.

What didn’t go as planned was that the seed in vinegar grew the least, and got shriveled and wrinkly. Also, at least some of the liquid in each container evaporated. Almost of all the water evaporated, more than half of the food dye liquid evaporated, but almost no vinegar evaporated.

If I were to do this experiment again, I would do it differently by starting out with more liquid in the containers for the seeds to soak in. I would also measure the amount of liquid left in each of the containers and compare that with the amount I started with.

After doing this experiment my questions now are:

Why did the water evaporate?

 Why did the food dye evaporate?

 Why did the vinegar not evaporate?

Why did the seed in vinegar shrivel?
