In the human body, ENZYMES help speed up chemical reactions.
Today we take a piece of raw pork liver and add it to Hydrogen Peroxide. Raw liver contains an enzyme called "catalase" which has a job of breaking the bonds in hydrogen peroxide. When those bonds are broken, atoms rearrange themselves and new products are formed.
In today's lab, we discover the new products
This is the criteria for the lab write up: Liver Latte Lab
Your lab must include the following
1. First and Last names of all investigators
2. Purpose of lab: write about how this lab illustrates the law of conservation of mass. Explain how the lab relates to the law
3. Materials: write a complete list of materials that we used
4. Procedure: write a step by step procedure (including illustrations if it makes it clearer) that is so well written that another person could read it and replicate your actions exactly
5. What is the question we are trying to answer? Write the two chemistry equations which were our possible outcomes of this reaction? Explain which one is the most possible. There was a gas formed: Oxygen gas or Hydrogen gas?
6. Results: Describe in detail what happened after you did the procedure. Include any photos you took. How did you know you made the gas, which gas?
EVALUATION IS OUT OF 25 IN TOTAL and you may work in a group of two or three

presentation is out of 5. for 5/5 it is typed with illustrations or photos .
for 4/5 it is pretty good but there are a few spelling mistakes. for 0-3 out of 5 it is in pencil or messy. I prefer this to be printed
10
Clear writing is out of 10. for 9/10 or 10/10, it is written with no English mistakes and it clearly communicates each part of the lab report. 7-8/10 it is very well written for 5-6/10 some parts are not so clear and the reader must guess what you are trying to say. 0-4/10, it is minimally communicating what happened
10
Paragraphs are insightful and your observations are well done. this is out of 10.
9-10/10, your observations and conclusions are well written and logical. It is brilliant
7-8/10 your observations and conclusions are very well done
5-6 your conclusions don't really logically follow from your results
0-4 your conclusions are not relating to your results at all
ACKNOWLEDGEMENTS
write all names and who contributed what including the % of their contribution. so two people who contributed equally would be50%
