Magic Grow® Capsule Observations To make a Data Table: Observations of Sponge Animal Capsules Label the type of observation Give your table a TITLE QualitativeQuantitative 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 Questions Using 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 water increases, then the rate of dissolving will increase. If the temperature of the water decreases, then rate 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 Give your table a TITLE Cold Water Room T Water Hot Water Make room for recording your DEPENDENT VARIABLE Label your SPECIFIC INDEPENDENT VARIABLES

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

Magic Grow® Capsule Data Analysis & Graphing Remember: DRY MIX D – Dependent variable R – Responding variable Y – Y-axis M – Manipulated variable I – Independent variable X – X-axis

Magic Grow® Capsule Data Analysis & Graphing Remember: TAILS T – Title A – Axis I – Intervals L – Labels S – Scales

Magic Grow® Capsule Data Analysis & Graphing A comparison of water T and dissolving rate Cold Room T Hot Water Temperature Time (minutes) General Independent Variable Specific Independent Variables Dependent Variable and Unit of Measurement Title

Magic Grow® Capsule Conclusion Use complete sentences Answer the original question Explain whether or not your hypothesis was supported by the data (never “right” or “wrong”) ALWAYS use actual data to support what you say
