1. SCIENCE SKILLS

2. Magic Grow® Capsule Observations Give your table a TITLE To make a Data Table: Label the type of observation Observations of Sponge Animal Capsules Make room for recording your DATA

3. 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?

4. 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?

5. 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.

6. 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

7. Magic Grow® Capsule Procedure • Repeated trials are needed to make sure the data us reliable. How are we going to do this?

8. Magic Grow® Capsule Data Collection Give your table a TITLE To make a Data Table: Label your SPECIFIC INDEPENDENT VARIABLES Time for Capsule to Dissolve Make room for recording your DEPENDENT VARIABLE

9. 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

10. 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

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

12. Magic Grow® Capsule Data Analysis & Graphing 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

13. 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
