Assignment 11: do a lab report on this lab! /10
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 kinetic molecular theory. Explain how the lab relates to this theory 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. Results: Describe in detail what happened after you did the procedure.
6. Write a conclusion
EVALUATION IS OUT OF 15 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 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
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.
It is written clearly, with insight
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%
I am absent today due to unexpected illness. Our Dry Ice Lab is therefore postponed to Thursday. Please open the windows and turn on the fans on low for ventilation.
Today, you will learn about the different types of reaction and review these types with the teacher.
Here are some practice problems to work on today. If you did not get the sheets in class you can do those problems to practice. This material and the study guide questions will be on this friday's quiz.
TEAMS ASSIGNMENT:
For 10 marks, make a lego model of each type of reaction. Label your lego reactions and photograph it with your maple leaf. If you are working from home, use any material you have on hand to create the models.
FYI if you are working from home, I will upload clear pictures of the bushtit nest here on this blog and on TEAMS, so you may do this assignment.
Investigation: Write a report as a two page document or slide show.
1. a. Here is some info on Bushtit biology right here: an excerpt from the website:
"Bushtits need to eat 80% of their body weight each day to keep up with their speedy metabolisms when weather is warm- they eat even more when it cools down. According to a study from 1907, bushtits in California had diets that consisted of 81% insect matter through most of the year, and which increased to 100% insect matter in the spring. "
write 10 points which characterize bushtit biology
1.b. Observe the nest that was found and draw it.
Take clear pictures of sections of this nest and try to identify what was used to make the nest. What do you think was used to construct this nest?
2. NEST SAMPLE (shared microscope) : Observe the tiny sample of the nest under the microscope and report what you see. Can you see the spider silk? The moss? feathers? Take a picture with your camera if you can.
3. COLLECT YOUR OWN SAMPLE OF a similar species of MOSS and LICHEN that is NOT from the nest from outside and examine this magnified either under the microscope ( OR using your camera to take a really close shot ) and draw your sample. Answer this question: What properties of moss make it suitable for nesting material?
4. Listen for the sound of a bushtit around our school. Observe for bushtits over a few days. Draw a map of where and when you hear this sound and include it in the report.
The sound can be found in this video here
5. Optional extra observations: Some of you began looking at other interesting specimens in our class and using our microscopes. If you looked at other specimens and photographed them, include them here too. If you did not, no worries, number 5 is optional.
Evaluation
17-20 - This is a beautifully presented assignment with clear observations, photos, drawings and observations. It is insightful and excellently done. It is typed or written in ink and in colour
13-16 - This assignment is complete and very well done with great photos and observations. It is in pencil
5- 12 - This is a good start with some good observations but it is incomplete
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.
