We used universal indicator, a known acid and a known base to create as many pHs as possible.
Purpose: To create as many different colours as possible for pH
Materials: Vinegar, Water, NaOH
Procedure: Write down your step by step procedure for creating the different colours.
Observations
Write some observations for your lab. What happened when you mixed liquid in a certain order? How did your group manage to achieve different colours from only 3 colours.
Using your photos of your lab, indicate the pH of all the different colours.
Conclusion: Write a paragraph describing what you learned. Explain how this lab demonstrates the pH scale.
EVALUATION IS OUT OF 25 IN TOTAL and you may work in a group of two or three
5
presentation is out of 5. for 5/5 it is typed with illustrations or photos and emailed to msngscience@gmail.com. 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%
