MAGMA LAB

The Constructive Side of Volcanoes

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).

HOW HOT IS MAGMA? Magma can range from 700-1300 °C

(1300-2400 °F)

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 LABThe Constructive Side of

Volcanoes

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.
