1. How to Write Up a Proper Lab Report

2. Title It is not necessary, but you can be creative with the title of the lab as long it is still identifiable. Ex) Breaking the Ice, Melting Ice, Ice and The Scientific Method Please include your FULL NAME, period and date near the top of your lab (right hand corner preferred.)

3. Purpose and Standard Purpose and Standard Optional but helpful (Good for ↑ points) Purpose: Why are we doing this? The purpose of this lab is to practice using the scientific method and to learn the proper technique for writing up a lab. Standard: Can copy from board or spiral 1.1 Plan and Conduct a scientific investigation to test a hypothesis.

4. Hypothesis and Materials Hypothesis: What do you think will happen? What are you expecting? The ice will melt if I sit on it. Materials: What will you be using? (list everything!) IceScale Ziplock baggieMe

5. Procedure List everything Step by step. We should be able to re-do your experiment without any extra explanation from you. 1. Place four ice cubes in a Ziplock baggie. 2. Double check that baggie is closed. 3. Weigh baggie and ice together 4. Sit on baggie until ice melts 5. Weigh baggie and melted ice

6. Observations / Data: Observations / Data: Write down what you see, hear, taste (be careful) or smell. Organize data into some understandable form. Label your units! There was a leak in the bag, so some water came out The bag was very cold Ice is hard to sit onDirt stuck to the bag My body became colderExample Data Table

7. Conclusion: (Most Important) Did your results match your hypothesis? Why or why not? Did anything surprise you? What did you learn? What would you do differently next time?

8. Conclusion Example: The ice melted when I sat on it, proving the hypothesis true. However, I do not think this is a good system for melting ice because a lot of the cold was transferred to my body and it was very uncomfortable. Also, weighing the ice before and after it was melted really did not help since there was a hole in the baggie and a lot of the water leaked out. Also, the rule of conservation of mass states that mass can neither be created nor destroyed, so even if all of the water had stayed in, simply weighing it before and after would not tell me how much ice was melted. Next time I would weigh the ice before and after the melting process to determine how much was melted. Also, I might try a different technique such as hot water or using solar energy because it was very uncomfortable to try to melt it with my own body heat and it took a long time. I might also use a stopwatch to measure exactly how long it took the ice to melt to add to the accuracy of the lab.
