This was mould growing on the leftover glue from the paper mache.
We got out the magnifying glasses and gave the mould a good look over. We turned it over, we examined it carefully. We discovered that where it connected with the sheet it was red, then it was black/blue/green and on top it was white.
What is it growing from mom?
Well.. take a closer look lad. Can you find more mould and see where it's coming from???
After some careful looking I got the excited shout of THE GLUE mom!!!
We decided to conduct an experiment.
We know that mould like wet/damp environments. We learned this last year.
So we put some red/dark mould into a test tube with water. We put some white mould into some water. We put some mould into a test tube that was dry. and then the lad asked.. what if we bury it mom? I don't know, sounds like a good experiment to me says I.
Math, Measurements and Geometry.
Did you know that ALL these jars are sold as quart jars? Did you know that 4 cups equals one quart? Well let me tell you that these jars aren't all quart jars.
Some are CLOSE, but to me close isn't really accurate (and neither to the lad). The wide mouth and the fatter of the mason jars are actual quart jars. The thinner mason jar is 3 3/4 cups, the one with the yellow line is JUST barely 3 cups. So NOT all quart jars are quart jars. :) It's good to know these things when one eats fruit at night and just ASSUMES that they are all equal (and counts calories). :) The lad thoroughly enjoyed this project and then started to learn about displacement.
He dropped in marbles, flour and a variety of other objects and learned what they "measured" by how much water they removed from the container. Good learning done here. :)
Of course said I... we don't want to hurt anyone.
Makes me smile.
