Time to slow down a little!

We have 4 weeks left and still a lot to do! However we're slowing down a little both in Chemistry and Adv. Biology so that we make sure we get the material covered completely.

Biology

We looked at onion epidermis cells that were stained with iodine to assist with identifying cell structure. We also looked at cork but it is always difficult to get cork cut thin enough to accurately see the orderly nature of the cell structure. We also looked at prepared slides to assist with identifying both plant and animal cells.

Move ahead into Module 7 with your reading and make sure you do your OYO and vocabulary listing.


Chemistry

We finished discussing all of module 6 this week and spent today working on practice problems in class. After working problems by themselves, it was decided that most of the class could use an extra week to cement our knowledge of stoichiometry. We will NOT have a test next week and will continue working until everyone is more confident. So stay in module 6, re-reading and doing practice problems. In this case, practice really does make perfect.


Advanced Biology

We completed half of module 6 this week (to p. 165) but the muscle identification is so intense that we stopped there and will pick up with the other half next week and will test on the 2nd half of module 6 on Wednesday. The test should not be that long which will still give me time to start prefacing the next module so that we don't lose too much ground.

I was very pleased with the test grades today - good work everyone!


Have a great weekend!!

week 10

Biology

We finished module 5 this week and took our test on modules 4&5. If you were not here for the test then I will give it to you when you come back as a take-home test. We will be moving into Module 6 and our study of plant and animal cells next week. There is a lot of vocabulary for this module so make sure you keep up with it or you will get overwhelmed. We will be looking at cork structure as well as onion epidermis for our lab next week.

Chemistry

We worked on stoichiometry this week and I gave a list of steps to follow to solve stoichiometry problems. Keep this available as you work through the OYO questions this week, finishing out the reading of Module 6.
Our experiment demonstrated limiting reactants as we inflated balloons by using baking soda and vinegar. Finish your lab write-ups and keep your notebooks up to date please! Our lab time next week will be used cementing our knowledge of stoichiometry problems.

Advanced Biology

We got half way through our module on muscle anatomy and will finish this module up next week. We will be having a test on Wednesday which will cover muscle physiology and anatomy. The anatomy will be broken down into muscle "regions" so it will be easier to study them this way.
Remember that your coloring book is also a great studying resource!

Have a great weekend!

Week 9

Biology

We completed our osmosis experiments today as well as a demo on diffusion. Please complete module 5 reading, making sure you keep up with the "OYO" and your vocabulary lists. I will be doing a notebook check next week so please make sure your books are up to date!




Chemistry

We finished module 5 and will be moving into module 6, stoichiometry, next week. Read to P. 182 in Module 6 - also, make sure your notebooks are up to date and that you have completed the calculations for our "Measuring the width of a molecule" lab. 5pts of extra credit will be awarded to the students that complete their calculations and have them in their notebooks when I do a check next week!

It is really important to keep up with the reading and the "OYO" questions through this next module! If you are struggling, then please let me know as we are going through it!



Advanced Biology


We have finished up Module 5, the physiology of muscle and are moving into Module 6 where we will work on identification. Please read to p. 165 in Module 6 and complete the "OYO" questions as well as the vocabulary list.



Have a great weekend!

Week 8

We were missing a lot of students today due to the PSAT as well as illness. We are officially over the halfway point and now is the time to reach deep for more energy so that we can finish well. I know many of you have lots of assignments piling up, but I encourage you not to fall behind on your reading or your notebooks. Class will go so much smoother if we are all on the same page!

Biology

We worked with bread molds and cheese molds today. Not many things gross me out, but blue cheese sure does! For next week, read to p. 140 in Module 5 as we begin the "Chemistry of Life"! You will need to choose one experiment - either 5.1 or 5.2 to complete at home. Please make sure that you do the write-up for the experiment that you did at home because we will be sharing results in class!


Chemistry

Today we reconstructed a model of the decomposition of water. It took a little problem solving, but both groups got positive results!

We are entering the world of moles as we get ready to hit the heart of chemistry - stoichiometry! Please finish reading Module 5 do ALL the OYO problems! These give you valuable practice as we start to work with converting from grams to moles. We will finish Module 5 with ample practice converting!

Please make sure that if you do not understand any of the concepts, that you don't wait until right before a test to tell me. I am more than willing to help but I can't do that if I don't know you're struggling.


Adv. Biology

With only 2 students today, it was a very laid back class. We viewed striated muscle under the microscope and worked on coloring exercises 5. 1 and 5. 2. Please complete these coloring exercises at home!

We will finish reading Module 5 this week. Make sure you keep your vocabulary up to date as well as the OYO questions. !



Have a great weekend!

Week 7

Week 7 is completed and we're almost to the middle! Let's not lose our pace and keep working to finish strong!

Biology
This week we entered the Kingdom of Fungi. We took a walk this morning to find mushrooms which we dissected and attempted to find spores. We were able to find a few to view under the microscope. We also made slides from dissolved yeast which we stained to be able to see budding yeast cells. For next week, finish up module 4 and keep up with your vocabulary list and your OYO questions. Please make sure your notebooks are up to date! You never know when you might need them! Strong hint!

Chemistry
We finished out module 4 this week and worked on balancing equations. We also took a test today on Modules 3 & 4 and the grades were much better this time. We start talking about moles next week in Module 5 as we lead up to stoichiometry. Complete your reading to p. 149 and do the OYO questions as you read.

Advanced Biology
We finished up module 4 this week and took a test on Modules 3-4. The grades were great! Good work! We also had some creative fun time making all of the synovial joints out of edible substances! A great stress reliever after the test! For next week, read to p. 136 in module 5 and do the OYO questions and your vocabulary list!


If you missed a day this week then just go by the syllabus to know your assignment. If you missed a test, then I will be give it to you next Monday. Please try and bring it back to class with you on Wednesday.

Have a great weekend!

Week 5

Well it was a rainy end to our week but a productive one! Here's the breakdown of the week by class.

Biology

We viewed our pond cultures again today and the egg cultures were definitely the winner! I may give these cultures a few more days to grow and pull them out again on Monday and see if we can see some of our protozoa on a larger scale. The ones we saw today were quite small! We were able to see a few Euglena and some Paramecium, however.

Please finish reading Module 3 next week and complete the OYO questions and vocabulary lists. We will have a short test on Modules 1-3 on Wednesday. Please have your notebooks up to date!


Chemistry

I returned the chemistry tests and gave the quizzes on the first 20 of the periodic table. The grades were fairly good but we do need to buckle down some. Remember to always label your answer with the correct unit!

Our experiment today showed helped to highlight the difference between covalent and ionic compounds in a tangible way.

Read to p. 113 in Module 4 for next week and complete the OYO questions. Our lab time on Wednesday will be very busy so please come prepared - that means read over our experiments before you come! We will be doing Exp. 4.1 and 4.2 in class. Steps 1 & 8 of Exp. 4.2 will need to be done at home before you come!! Make sure your lab notebooks are up to date!



Adv.Biology

We used our skeletal models today to help solidify our memorization of the skeletal system. Many thanks to Shelby's family for letting us borrow "Stinky". We also have "Steve" and "Bonita", our smaller models to assist us. There were quite a few coloring exercises for us to do this week so we did not get them all finished. Please try to go through these at home. The drawings of the cranial bones are quite good and will really help with your memorization.

For next week, read Module 4 to p. 110 and complete the OYO questions and vocabulary listing. We will do Exp. 4.2 in class but Exp. 4.1 will need to be done at home!



Have a great weekend!

Week 4

Well, week 4 is finished and we are nicely settled in. Everyone worked hard this week and I was pleased with the progress we made in all the classes.

Biology
Today we made slides from pond cultures. We saw good bacterial growth and some amoebas and diatoms, but no other live protozoa. You should finish your lab report including your hypothesis as to which culture would produce the most organisms.
Read to p. 82 in Module 3 making sure to complete the "OYO" and vocabulary list. We will be doing part 2 of our pond cultures hoping to see algae and protozoa.

Chemistry
This week we spent doing quite a bit of review of Modules 1 &2 before briefly touching on Module 3. I gave a test today and I will return those to you on Monday. Good news - no lab write-up!
Finish the reading on Module 3, completing the "OYO" questions. Work on memorizing the 1st twenty elements of the periodic table by name, atomic number and abbreviation. You should also be able to fill those first 20 in on a blank chart. Your quiz on that will be on Wednesday. We will also be completing Exp. 3.2 on Wednesday.

Advanced Biology
We went over the first half of Module 3 this week and completed Exp. 3.1 and 3.2 in class. The coloring exercises are very detailed and will need to be finished at home if they were not in class.
Finish reading Module 3 to the end and complete the "OYO" questions. We will be working with our models and completing Coloring exercises 3.2 - 3.6 in class. They should be easier than today's exercises.

If you missed a day this week then just go by the syllabus to know your assignment. If you missed a test, then I will be mailing it to you. Please try and bring it back to class with you.

Have a great weekend!

Week 3

It was a shorter week but we managed to pack a lot in today! Please remember to keep up with your reading and keep your notebooks up to date!

Biology

Today we viewed bacterial slides in preparation for our pond cultures next week. For Monday, read Module 2 to the end and answer the "OYO" questions and keep up with your vocabulary. For Wednesday, make sure you read over the experiment 2.1 so we can get started right away!


Chemistry

Today was a more complex lab (2 labs actually) that took several steps as we worked to calibrate our thermometers then we worked to calculate the specific heat of an unknown metal. Make sure you are reading over the labs we will be doing before coming to class so that you know what to expect. And I'll know to purchase ice in the future!!! I will be sending out an email individually to the students with sample data to help them through the calculations. Please try and work through them the best you can! We will go over the calculations as a group on Monday!

For Monday, you need to read Module 3 to p. 82 stopping before the Law of Multiple Proportions. We will also have a short test on Monday on Modules 1 & 2. We will be completing experiment 3.1 on Wednesday.


Advanced Biology

Today we finished out Module 2 and took a short test. I will have those graded and back to you on Monday. Read to p. 72 for Monday and do the "OYO" questions. We will be doing Lab 3.1 and 3.2 on Wednesday as well as the coloring exercise 3.1. Please make sure you bring your coloring books (sounds like preschool, huh!) with you each Wednesday. I know it's one more large book for your backpack but it will really help us with our identification!

I believe that's all for now! As always, I am available for questions if you have them!

Thanks for being such amazing students!

Week 2

Well week 2 is finished and I think we're all looking forward to a long weekend. Remember that there is no class on Monday and I will see everyone on Wednesday. I clarified assignments in class but here is a recap for each class. We have a lot to accomplish since we only have 1 day next week but I'm confident we can get it done if everyone is prepared!

Biology
Read Module 2 to p. 52 keeping up with the vocabulary listing and the "On Your Own" questions as you go through the reading. We will be viewing and drawing bacterial slides in preparation for doing our pond cultures on week 4. You should include your drawings that you made today of cheek cells but no formal lab report is due.

Chemistry
Read all of Module 2 (a shorter module) and be prepared to complete experiment 2.1 and 2.2 in class. Make sure you complete the "On Your Own" questions as you read. You have one lab report due (Exp. 1.4, the one on density) but I would still like to see your data from your measurements from exp. 1.3. Make sure all your calculations are complete and that your significant figures are correct.

Advanced Biology
Read Module 2 to the end and complete your vocabulary listing as well as the "On Your Own" questions as you read. Complete the lab writeup on exp. 2.1 including your drawings ( you may leave them in a composition book as long as I can find them.) I will be doing a notebook check on Wednesday. We will also have a short test on Modules 1 and 2. My best advice is to use the study guide and your vocabulary listing as study aids.

Whew! Through week 1!

Well we made it through the first week! I'm enjoying getting to know all of the students and hope this will be the start to a fabulous year!

For ALL the science classes, here is a sample lab report that can be modified to your class.

Title - this will usually be the title of the experiment listed in the book. For today's Chemistry class it will be "Soda and Mentos".

Hypothesis or Objective: This is a statement that describes what you think will happen in the experiment OR what you hope to achieve in the experiment. An example might be "To learn the parts of the microscope and accurately view prepared slides." or "To prove that Diet Coke is the best medium for creating a mentos geyser."

Supplies or Materials list: Simply list what you used to complete the lab.

Procedure: This is a step by step of what you actually did. Describe the process of completing the lab. An example might be: Microscope set up and light turned on. Prepared slide of spider placed on stage in it's lowest position and then viewed under 4x, 10x and 40x magnification. See attached drawings." Or it could be: "Diet coke uncapped and placed on the ground. While wearing eye protection, placed one mentos quickly into the bottle of diet coke and moved away. "

Conclusion: This is the place to tell what happened with the experiment. Did it go as planned? If not, what are some possible reasons why it didn't. What did you learn or accomplish? If you had a hypothesis, was it supported?

That is what I expect to see in a lab report each week if we do a lab. Please make sure they are typed up and in your notebooks by the following Monday. They won't help me if they are still on your computer!


On each syllabus I have put in when I will be giving a test. It is usually after every 2 modules. If your parents would like for you to take the module tests at the end of each module then that is up to them. I have tests planned out and it helps me to know where you are in your understanding of the material. If your parent would prefer you not take my tests and just take the module tests, then please let me know.

The syllabus has your reading assignment - when it says "Week Two" the expectation is that you will have completed the reading hopefully by Monday of that week and the lab that is mentioned will be our Wednesday class.

If you have any questions, please let me know! And thank you again for letting me "borrow" your children!

We're almost there!

I sent out the syllabus for the Biology and Chemistry classes this evening so if you have not received an email with that information, please let me know at thematthews@bellsouth.net and I will resend that. I will also have hard copies of the syllabus available on the first day of class.

I should have the syllabus for the Advanced Biology class out by Sunday (Monday at the latest).

I will be taking my son up to college and getting him settled in tomorrow (Friday) so I will have limited availability then.

Please note that all of the classes require reading approximately half the module prior to class so that we can do our introductions and expectations for the class and then hit the ground running.

Hope you have a great weekend!
