Growing Crystals

For my birthday, I got a Smithsonian crystal-growing kit. I learned that crystals are formed when atoms attach themselves together in patterns.

First, I grew the yellow one, called “golden citrine.”

I mixed the golden powder with boiling water, and stirred it.

Once everything was dissolved, I let it cool for 5 minutes.

I put a rock in the cup, so that the crystals could grow on something.

I then poured the liquid into the cup, and put a few crystals of the chemical on the rock.

Then I had to wait. (I think I’m good at waiting.) By morning, crystals had started growing.

After a week, it looks like this:

Out of the cup, it looks like this:

Mix Colors with Your Eyes

I am just a kid, and I am already a scientist! Today I learned about color.

My hypothesis is that you can get different colors by mixing them.

Let me tell you what I did. I mixed color tablets with water, and then held the test tubes up to the window.

First I did blue and yellow one at a time. Then I held them together. Guess what blue and yellow make when mixed? Green!

Here are some other combinations I tried:

Blue plus red makes purple.

Yellow plus red makes orange.

Try this experiment yourself.
