Which object melts the most in a microwave?

Big Question

• Which object melts in the microwave the most?

Explanation of the big question

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

My Hypothesis

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

Explanation of the hypothesis

• I think butter will melt the most because it is so easy to cut when it is warm

5-8 interesting facts

1. All my objects change shape 2. All my objects are food besides the crayon3. My objects will be uncovered when in the

experiment4. My objects can blow up under a certain

amount of pressure5. The microwave will be on high power6. All my objects will change shape under 1 min.

Materials

1. Butter2. Crayon3. Hot dog4. Marshmallow5. Cheese6. Microwave7. Paper Plates8. Ruler

Procedures

1. Collect materials2. Put object on paper plate3. Measure how tall the object is4. Stick in microwave5. Cook for or 30 seconds or 1 minute6. Take out object7. Measure how tall object is8. Write down all the info

Variables

1. I can change the time I put it in the microwave

2. I can change what I stick in the microwave3. I can change how long I let it cool4. I can change how tall the object is

4-5 observations

1. Most of them moved2. They mostly expanded3. All objects did something 4. The crayon burnt the plate5. The marshmallows expanded

Analysis of DataThe marshmallow after 30 seconds changed from 1 cm. to ½ cmThe marshmallow after 1 min. changed from 1cm. To 1 ½ cmThe 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 cmThe cheese after 1 minute changed from 1 ½ cm to 1 2/5 cmThe crayon after 30 seconds did not change from 4/5 cm.The crayon after 1 minute changed from 4/5 cm. to 1 ½ cmThe 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

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.
