Science test part 3
Dear grade 10s, Monday for day1, and tuesday for day 2 you'll do part 3 of the balancing equations test. On the first page, you will do 11 balancing equations problems. Your full name is also worth one mark! On the back of the page, you must summarize and draw all the main concepts of this unit on types of reactions. Write EVERYTHING you know about types of reactions and balancing equations. Use drawings. Note that some of you started part 3. You will not get your previous paper back today. Please simply answer the questions on this new sheet. For those of you who still need time for part 2, please talk to me when I return to class. You will be given the opportunity to do it with me.
Thank you,
Ms. Ng.
Thank you,

lab report for Mg + Cupric sulphate, REMINDER FOR TEST NEXT BLOCK
1. First and Last names of all investigators
2. Purpose of lab: write about how this lab illustrates the types of reactions especially single displacement
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 correct equation for this reaction
6. Results: Describe in detail what happened after you did the procedure. Include any photos you took. How did you know you made a solid? a new compound?
7. Write your conclusion in paragraph form.
EVALUATION IS OUT OF 25 IN TOTAL
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%
