Crystal Science Projects: Crystal Tree Project
Crystal Science Fair Project - Crystals and Temperature
The purpose of this crystal science project experiment is to determine the temperature at which crystals grow best.Background:
Research information on crystals. Answer the following questions: What are crystals? What are the chemical processes involved in crystal growth? Why are they important? What is a supersaturated solution?
Hypothesis:
From your research you will predict the solution in which crystals will grow best - hot, room temperature, or cool.
Materials: (Adult supervision of kids is always recommended.)
- 9 Crystal growing trees (4 individual trees in a package, you will need 3 kits) - Suggested kit:
| Scientifics Online: Magic Crystal Growing Tree | ages 5 and up |
| Science Kit: Magic Crystal Growing Tree | ages 5 and up |
- thermometer
- paper
- pencil
1. Gather materials needed for your experiment. List all materials from your crystal tree project kit.
2. Follow instructions on how to assemble your trees.
3. For 3 of the kits, follow instructions and pour the provided solution into the bases of the trees. Make sure the liquid is room temperature.
4. Place trees on a counter or table.
5. Observe the trees and record the time it takes for crystals to start forming.
6. Allow crystals to grow for the recommended time.
7. Take the solutions provided in 3 other crystal tree project kits and allow them to cool in the refrigerator for an hour. Remove from the refrigerator and record temperature.
8. Follow instructions from the kits and pour the proper amount of solution into the base of each of the 3 trees.
9. Place trees in the same location as the previous trees.
10. Observe the trees and record the time it takes for crystals to start forming.
11. Allow crystals to grow for the recommended time.
12. Heat the solutions from the final 3 tree kits to a near boil. (Ask parent for assistance.)
13. Allow the solutions to cool on a counter for 3 minutes and record the temperature.
14. Follow instructions from the kit and pour the proper amount of solution into the base of the final 3 trees.
15. Place trees in the same location as the previous trees.
16. Observe the trees and record the time it takes for crystals to start forming.
17. Allow crystals to grow for the recommended time.
18. Record observations for each group of crystal trees.
Results:
Record your data and compare your results. Graph and chart your data. How long did it take crystals to grow in each group? Which crystals grew fastest?
Conclusion:
Summarize what happened in your crystal science fair project experiment based on your results. Explain patterns in your data. Did your data support your hypothesis? If not, explain why. Evaluate your crystal tree project and make suggestions for improvements.
