Although you studied mitosis and meiosis last year, it is worth a look again to make sure you have all the steps down correctly. It will help you to understand our next unit which is Genetics. This video explains how alleles are connected to the steps of mitosis and meiosis. I also assume this is familiar from last year.
Your teacher will review these steps, explaining some of the complex parts and give you time to answer the questions. Next, your teacher will review the answers to the questions. After this you will do a creative assignment to demonstrate that you understand this material.
Please watch this videoThe mitosis slides are located in the second back room. They can be a challenge to look at. If they can be found then your teacher will assist you in observing these prepared slides .
Draw mitosis under high power in the light microscope in 3 pictures. Label the stages of mitosis

steps of cell cycle: you should write a table showing the steps as well as the
FORM OF DNA
role of other organelles
1. INTERPHASE -
a. cell is undergoing growth. After a period of growth, it prepares to divide
b. cell replicates its DNA. Nuclear membrane is still intact
2. PROPHASE
Nuclear membrane disappears and the chromosomes are visible
3. METAPHASE
chromosomes line up in the middle and Centrioles send out the spindle fibres to attach to the centromere
4. ANAPHASE
centromeres get ripped apart and thus the chromosomes get ripped apart into separate chromatids
5. TELOPHASE
nuclear membrane reforms around the chromatids
6. CYTOKINESIS
chromatin is in the nucleus now.
Read the following notes. Ways to increase rate of reaction
Assignment : Do the study questions, put your name on it and hand it in when done Answer key is here. or here Your teacher will make a list of who finished this assignment.
Watch my videos on DNA, review the concepts in the slides below and use class time to complete the assignments which are due on Friday.
We know that plants are important to the ecosystem because they photosynthesize. Did you know that some plants are legumes and these are special because they have ROOT NODULES which are nitrogen fixers. These root nodules are little rooms where Rhizobium bacteria convert nitrogen gas into ammonium and then Nitrobacter bacterium in the soil converts ammonium into nitrates. Plants can absorb nitrates to make plant protein. When those plants are eaten by animals, then animals use the nitrogen to make animal protein. You can say that all the protein on your body (muscles, enzymes, hair, fingernail etc) was built from nitrogen which was fixed by Rhizobium at some point in time.
ASSIGNMENT: 10 points
Only certain plants contain these root nodules...amongst them are bean plants and clover plants. Look at the morphology of clover plants below. Look on our school grounds and find AS MANY DIFFERENT GENETIC VARIETIES as you can. Upload your clover pic on a word doc or ppt and hand in as an assignment.
What is the identity of the three liquids? Write/draw your procedure in cartoon format and upload your observations in form of photos. Explain your findings using vocab words from our chem unit: acid, base, salt, indicator, neutralization, pH, equation.
ALSO, USE THIS LAB, to explain HOW the "red wine, white wine" magic trick worked.
This is the Chemistry practice sheet Here is the Chemistry practice sheet key.
TEACHING NOTES: First lets review the main types of reactions:

Lab Jounral assignment includes the following labs:
Assignment: Write up our lab on Calcium and water. FORMAT: paper write up or word doc or pdf or powerpoint
image by Katelyn M |
Your lab must include the following
1. Your First and Last name
2. Purpose of lab: The purpose of the lab is to find out what happens when you add calcium to water. PART I Describe the teacher demo that preceded this lab.
You will practice drawing Bohr Diagrams and Lewis diagrams. You can practice this by working through this Study guide on the same topic and the Answer key or you can work on any worksheets provided in class.
Your teacher will make a list of your names from the attendance roster and give you 5 marks for completing this work
An analogy for Atoms, Compounds and Formula, drawn by SN This video is the first in the series for beginner Chemistry. In this video, I use the analogy of the atom as units very much like "lego bricks". This analogy was first used by researchers in MIT.
