### SCIENCE SKILLS

To make a Data Table:

Label the type of observation

Observations of Sponge Animal Capsules

Make room for recording your DATA

• Does the color of the capsule affect how long it takes the toy to change shape?

• What is the effect of adding substances to the water on how long it takes the capsule to dissolve?

• Does the temperature of the water affect how long it takes the capsule to dissolve?

Magic Grow® Capsule QuestionsUsing Effect & Affect

• Does the temperature of the water affect the time it takes the capsule to dissolve?

• What is the effect of the water temperature on the speed of dissolving?

• If the temperature of the waterincreases, then the rate of dissolving will increase.

• If the temperature of the waterdecreases, thenrate of dissolving will increase.

• Independent variable –T of the water

• Dependent variable – Time it takes for the capsule to dissolve in minutes

• Controlled variables – type of capsule, type of water, amount of water

• Repeated trials are needed to make sure the data us reliable. How are we going to do this?

To make a Data Table:

Time for Capsule to Dissolve

Make room for recording your DEPENDENT VARIABLE

• To make a Graph

• Decide what kind of graph is appropriate for the data.

• We are comparing T, so a bar graph will be best

Remember: DRY MIX

D – Dependent variable

R – Responding variable

Y – Y-axis

M – Manipulated variable

I – Independent variable

X – X-axis

Remember: TAILS

T – Title

A – Axis

I – Intervals

L – Labels

S – Scales

Title

A comparison of water T and dissolving rate

Dependent Variable and Unit of Measurement

Time (minutes)

Specific Independent Variables

Cold Room T Hot

Water Temperature

General Independent Variable
