### SCIENCE SKILLS

Magic Grow® Capsule Observations

To make a Data Table:

Label the type of observation

Observations of Sponge Animal Capsules

Make room for recording your DATA

Magic Grow Capsule® Questions
• 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?
Magic Grow® Capsule Hypothesis
• If the temperature of the waterincreases, then the rate of dissolving will increase.
• If the temperature of the waterdecreases, thenrate of dissolving will increase.
Magic Grow® Capsule Procedure
• 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
Magic Grow® Capsule Procedure
• Repeated trials are needed to make sure the data us reliable. How are we going to do this?
Magic Grow® Capsule Data Collection

To make a Data Table:

Time for Capsule to Dissolve

Make room for recording your DEPENDENT VARIABLE

Magic Grow® Capsule Data Analysis & Graphing
• 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
