Handleiding

2. Measuring volume

You will need:

Gummy mold tray, measuring cup, food

coloring, spoon, tablespoon, teaspoon

Here’s how:

Fill the measuring cup with exactly

one cup of water.

Add two drops of food coloring. The

purpose of the food coloring is only

to make the water easier to see.

Using the spoon, carefully ﬁll each

mold in the tray with colored water.

Try not to let any water drip outside

of the molds.

When the tray is full, look at how

much water is remaining in the

measuring cup. Subtract this number

from one cup to determine how

much liquid the gummy mold tray

holds.

How much water does it hold?

How might you calculate how much

water each cavity holds?

GEEK

OUT!

WHAT’S HAPPENING?

The gummy mold tray holds about two-thirds of a

cup of liquid. To calculate the volume of each cavity,

you could use a small measuring spoon to measure each cavity

separately, or you could assume each cavity is approximately the

same size and divide the total volume by the number of cavities.

This type of assumption is common in science, but when sharing

your calculated volume, be sure to include that it was based on

assumed knowledge and was not measured exactly. This is the

level of detail scientists use when reporting their results!
