What Type of Water does Egg Crystals Grow the Fastest In?

Question: In what type of water do egg crystals grow the fastest?

Procedure:

• Get materials from amazon or stores - alum powder, eggs, supplies for the alum mixture/solution, gloves

• Prepare warm, room temperature, and cool waters and put the solution in each

• Blow out the eggs and dry them out

• Cover the inside of the eggshells with white glue then alum powder

• Test the egg shells in the water with the growing solution in it

• Put one eggshell in the warm water, one in the room temperature, and one in the cool

• Make a data table

Directions:

Materials: 1. Take the plastic egg and with the small paintbrush cover the inside of

Plastic egg or blown-out eggshell the egg with white glue.

Alum powder 2. Cover the entire egg with alum powder and leave it overnight to dry.

White glue 3. For the growing solution, mix 2 cups of very hot water with a craft

Small Paintbrush stick or spoon. Then, mix in an entire packet of colored dye.

Plastic or glass container Wear gloves the whole process.

Egg dye 4. Add ¾ a cup of alum powder to the dyed mixture and mix until

Hot water dissolved. Put it in the microwave if there are still remaining crystals on

Craft stick or spoon the bottom.

Latex gloves 5. Submerge each egg that has dried into the solution.

Drying rack or newspaper Keep the eggs in there for at least 12 hours.

6. Place each container of solution into different spots. One in the fridge,

one in the freezer, one in the heater room, and one on the counter.

7. When they are done growing, take them out and put them on the

newspaper or drying rack.

Hypothesis: I predict that the eggshell in the room temperature water will grow the fastest because the water won't be too warm or cool.

Conclusion: In my conclusion, I found out that the cold temperature is the best for a crystal to grow in. My hypothesis was incorrect because I predicted that the room temperature would be best and it wasn't. Therefore, my hypothesis was incorrect. To improve this experiment, I could have repeated it a few more times and made sure that my timing of checking them was right and the same.

Abstract:

Growing Crystals

Hannah Fuscaldo

I chose to grow crystals because I thought it would be an exciting project to do. I wanted to do this because I wanted to know how crystals grew in caves and how they formed. I examined what temperature was best for crystals to grow in. There were three temperatures: warm, cold, and room temperature. I predicted that the room temperature would grow the best and biggest crystal because the temperature isn’t too hot or cold, which makes it a perfect temperature and I thought that some heat would be better for a crystal to grow in.

To start my experiment, I needed to make the solution and blow out my eggs so they were just dried out eggshells. Once my eggshells were blown out and the yolks and whites were taken away, I covered the entire inside of the shell with white glue and then poured on the alum powder. While I waited for the shells to dry, I started working on making the growing solution. I mixed together 4 cups of very hot water, 2 cups of alum powder, and 8 drops of green coloring. Then, I stirred it until the alum powder dissolved completely. I split the solution into three cups. One for the hot growing crystal which would be placed in the heating room. One for the cold growing crystal, which would be growing in the outside refrigerator. The last cup for the room temperature growing crystal, which would just be on the counter where no one would touch it. I labeled all of the cups, so I wouldn’t confuse the three. Then, I tested them all and compared them each day, for three days, and recorded the crystals in my data log. I rated the crystals on a scale from one to ten, with ten being the highest and biggest crystal.

The data shows that the cold temperature is best for a crystal to grow in. Hot temperatures are the worst for crystals and room temperature is a little better than hot. The average for the cold was 4, the average for warm was about 1.3, and the average for room temperature was about 2.3. I observed that my results were clear. I think that cold temperatures are best for a crystal because the crystals in caves are born in cold climates. The cave is cold so crystals adapt to the temperature. I guessed that the result of this experiment was because stalagmites and stalactites grow in cold climates and they are a form of crystal.

By doing this experiment, I learned that crystals grow best in cold temperatures. My conclusions summed up the result that hot temperatures are the worst for crystals. My hypothesis was incorrect. I predicted that the room temperature would be best for the crystals to grow in, yet the result was quite the opposite. Therefore, my hypothesis was not right. I can conclude that my results were pretty accurate because I repeated the test three times, which I did the same steps. I tested the crystals and compared them three times then finding the average of each one. I tried not to have too many variables because I figured it would turn out more accurate. I think that this experiment could have been improved by having the same amount of alum powder on each crystal eggshell and maybe if I did it more times.
