If it’s Science Lab Day it must be Monday!
We pulled out the science gear and determined if iodine could detect starch in a solution. WOW, it turned it black (the test tube on the the left is iodine in water, 2nd from the left is iodine in a starch solution). The next two tubes dealt with detecting fat in solution, however it didn’t work for us. The far right tubes were used to see if we could detect protein in a solution. The second tube from the right contains a clear solution — water and a copper sulfate and caustic soda solution; while the one on the right turned purple when the copper sulfate and caustic soda solution was dropped into it.

Here’s an update on our bean seed:

The big green thing behind the bean is just construction paper. It held the kidney bean in place until it started growing roots. What is amazing today is the quantity of growth in the leaves. it is a full inch above the glass, growing a good 2″ today!

Hi Carole! What’s the big green thing in the glass with the bean seed?

Looks like fun. I’m jealous.

It was fun! Forgot to mention that SK also did a science lab and looked at his own skin cells and an onion skin’s cells using a high-power microscope (thank you to a local ps for lending us one!)
