STEM lab- can you “paint” macaroni?

May 4, 2012 in Elementary STEM

STEM lab- can you

The kids wanted to make macaroni sculptures which we do a lot during the winter. We water down glue and stick the macaroni together in all kinds of shapes. Sometimes we use peanut butter instead of glue and then coat them in birdseed and hang them in the yard.
This time- they wanted to “paint” them. Since maracorni will dissolve in water based paint, I had to use some of my sciency skills. We used 90% rubbing alcohol ($1 for a bottle at any drug store) and added food coloring in different colors. They had a ball and worked for hours on their art. They also learned a valuable lesson about the differences between water and alcohol.

STEM- staining skin. Pictures with Motic Cameras

Sometimes it is just fun to answer a kid question. This one came from my 8 year old. He wanted to know what the “cracks” in our skin of our palm looked like close up….We used clear tape to pull off some cells of my palm, stained them and then took a picture with the motic cameras. Fun Sat afternoon activity…
