  1. Which object melts the most in a microwave? By: Spencer Smith

  2. Big Question • Which object melts in the microwave the most?

  3. Explanation of the big question • I am going to test which object melts the most when you put it under heat from the microwave.

  4. My Hypothesis • I think that butter will melt the most in the microwave.

  5. Explanation of the hypothesis • I think butter will melt the most because it is so easy to cut when it is warm

  6. 5-8 interesting facts • All my objects change shape • All my objects are food besides the crayon • My objects will be uncovered when in the experiment • My objects can blow up under a certain amount of pressure • The microwave will be on high power • All my objects will change shape under 1 min.

  7. Materials • Butter • Crayon • Hot dog • Marshmallow • Cheese • Microwave • Paper Plates • Ruler

  8. Procedures • Collect materials • Put object on paper plate • Measure how tall the object is • Stick in microwave • Cook for or 30 seconds or 1 minute • Take out object • Measure how tall object is • Write down all the info

  9. Variables • I can change the time I put it in the microwave • I can change what I stick in the microwave • I can change how long I let it cool • I can change how tall the object is

  10. 4-5 observations • Most of them moved • They mostly expanded • All objects did something • The crayon burnt the plate • The marshmallows expanded

  11. Data( measured in centimeters)

  12. Analysis of Data The marshmallow after 30 seconds changed from 1 cm. to ½ cm The marshmallow after 1 min. changed from 1cm. To 1 ½ cm The hot dog after 30 seconds changed from 2cm to 1 ½ cm. The hot dog after 1 minute did not change from 2 cm. The butter after 30 seconds changed from 3 cm to 4/5 cm. The butter after 1 minute changed from 3 cm to 1/10 cm. The cheese after 30 seconds did not change from 1 ½ cm The cheese after 1 minute changed from 1 ½ cm to 1 2/5 cm The crayon after 30 seconds did not change from 4/5 cm. The crayon after 1 minute changed from 4/5 cm. to 1 ½ cm The pattern in this experiment is that under 30 seconds they barley change or not change at all. The experiment tested my experiment because I did butter in the microwave and my experiment proved it to be correct

  13. Conclusion • In conclusion my hypothesis was correct because I guessed that the butter would melt most in the microwave. My experiment answered my big question successfully. I would change the results if I could change something.I don’t know why some did change shape but not size.
