VISCOSITY Viscosity is the property of matter that allows it to hold it’s shape (or the property that allows it to resists flowing).
Low Viscosity means that it is more runny/thin (like water).
High Viscosity means that it is thicker (like honey).

MAGMA LAB Wear your goggles! Please use your larger bin to transport
your materials. When you are finished with your
magma please keep the small plastic bins stacked up (soil on top) and return them to the proper place up front.
When you are finished with both and the magma is returned, please try to clean out your large plastic bin as well as possible WITHOUT USING WATER.

LAVA LAB Wear your goggles! Please keep wax off the floor, tables, clothes, fingers,
etc. Please don’t break your solid block of wax. Once you get your hot wax don’t waste too much
time or it will solidify. Instead of getting a whole new batch of lava (wax)
save a little for step 7-9 (to pour into the water). After pouring some lava into the water try to pour as
much onto the wax paper as possible. When all of your wax is poured please bring me the
black lidded container. When you are finished bring the wax paper (with the
wax on it) and the beaker (with the wax and water in it) up to the front.
