Science Rocks: Growing Crystals

By: Talon B.

First Grade Science Project

See how candy crystals could grow the best

Scientific Method

What material would grow the best rock crystals?● Look at websites for ideas● Make a plan● Write down a recipe I like● Gather materials● Make hypothesis● Conduct the experiment

Materials● Recipe 1 c water, 3 c sugar, food coloring, flavor● clothespin, popsicle stick, dental floss, ribbon,

pipe-cleaner● 5 jars, 5 pencils, and tape to hold objects in place● Spoon and pan to heat the recipe● Notebook and pen for observations

Hypothesis

Looking at the gathered materials I felt that the clothespin would grow the biggest cotton candy crystals of all.

Plan

#1 Mix ingredients in pan until boiling.

Plan

#2 Dip items in mixture to saturate and let dry

Plan

#3 Let it dry and then put the objects in jars

Plan

#4 Take data and enter observations in my chart

Watched crystals grow from Jan 17- Jan 30● All jars had the same amount of ingredients● There was a different object in each jar to grow

crystals on

Conclusion

After watching all the candy crystals grow, the hypothesis was right! The clothes pin had the biggest and most crystals.

Science Rocks – especially when it is candy!

Growing crystals has SWEET rewards . . . . .
