From the Desks of Isaiah,Elijah and Hannah

This week we are studying matter, specifically density. We made a density jar with household liquids to see which were more dense. Molasses, syrup, water, oil and rubbing alcohol. It made a pretty layered look. We are going to put it in the fridge overnight to see if temprature effects it.

Carefully pouring in the ingredients.

Watching it seperate.

Ok no words just pure cuteness.

And now check out this video of our "plasma grape"

Plasma is what happens when you add enough energy (often in the form of raising the temperature) to a gas so that the electrons break free and start zinging around on their own. Since electrons have a negative charge, having a bunch of free-riding electrons causes the gas to become electrically charged. This gives some cool properties to the gas.
