In school this year we are working through the A Beka science book Investigating God's World. One of the investigator activities we tried was making a crystal garden using liquid bluing (can you believe this was a baby shower gift with cloth diapers before Riley was born over 13 years ago?! uh huh, and I still have it.), ammonia, water, salt, and broken bricks. Here is a photo progression of the crystals forming:
 |
| Day 1: Putting green food coloring & green coloring on 1 brick each |
 |
| Day 2 : white crystals forming on the side of the plate & on top of brick pieces |
 |
| close-up of 2nd day |
 |
| A few days later : bottom of plate is crystallizing as well. |
 |
| After 10 days or so. |
 |
| 2 weeks : no further progress, possibly mold on top of some crystals. |
 |
| Last photo before discarding. |
A small observation project to aid in our learning about God's gift of minerals!
