Grade 7 Science Cover Period 7 & 8

I’m so sorry because I know that you are all excited about the eyeball dissection but I’m sick today so we will do it next lesson.  I don’t want to scare your cover teacher!

Here is what to do today…

Eyes

  1. Open brainpop through your google account (9 dots in the corner!)
  2. Watch the brainpop video called “Eyes”.
  3. Take the quiz and send the results to me in the spreadsheet.  Do not choose to email me.
  4. Repeat the quiz until you have a minimum of 80%.

Light videos by Shea

Choose one of the videos below to watch with a partner.  You can watch more than one if you want.

   

Discuss the video you watched with your partner.  Do you both understand it?  If not, talk about it with someone else that watched it or watch it again and discuss the tricky bits.

For one of the videos, write a blog post summary of the video.  Your summary should include:

  • the main idea(s) from the video – what did you learn?
  • a picture/graphic that you found that is also about that idea and helps explain it

 

12B Cover Period 3 & 4

Hi Lovelies

Standard Level

  1. Organise yourselves into two groups.  If someone is away then you’ll just have to be one group and do both tasks.
  2. Create and informative poster for each of the following processes:
    Contact Process
    Haber Process
  3. Each poster should contain the following information:
    The equation for the reversible reaction involved in the process.
    The conditions necessary to maximise yield (to favour the forward reaction)
    The conditions actually used in industry – be specific and give actual numbers for temp and pressure.
    Reasons why in industry the ideal conditions are not used.
  4. You will find poster paper in the cupboard above the beakers and art supplies in the top drawer of the filing cabinet.  When you’re done, put the finished posters in the shower.
  5. If you finish early, there is a revision packet on the Google+

Friday next week there will be a test on Topic 7, with one question from each of topics 1,2,3 and opt D thrown in for good measure!  It is on the Verycross!  Yay!

Friday is study hall for you unless the posters aren’t finished.  However, if you still want to come and work on the revision packet in class so you can ask questions, feel free.

Higher Level

  1. Watch the following video explaining how to do calculations involving Kc and equilibrium expressions:
  2. Try these questions first to start you off.  The answers can be found at the link at the bottom of the page.  You will need to scroll down the page that is linked to find the answers.
  3. On the Google+ there are some past paper questions (3 exactly) for you to try that are a bit more difficult.

12 A Cover Period 1 & 2

Hi Lovelies!

Standard Level

  1. Finish your posters from yesterday.  Collect them from the shower.  There are coloured pens etc in M311 behind the sliding whiteboard as you enter.  Otherwise take them from my room but remember to put them back and try not to disturb Mrs Harrison’s class too much.
  2. Each group needs to share and explain their posters with the HL students and each other.  At the end of the lesson please return the posters to the shower and I will staple them to the roof of our room.
  3. There is a revision packet on the Google+ waiting for you as you’ve now finished this topic.

    Friday next week there will be a test on Topic 7, with one question from each of topics 1,2,3 and opt D thrown in for good measure!  It is on the Verycross. Yay!

    Friday is study hall for you but feel free to come and work on the revision in M313 so you can ask for help if you need it.

Higher Level

  1. There are some past paper questions (3 to be exact) on the google+ using calculations for you to  try.
  2. The standard level students will explain to you their posters on the Contact Process and the Haber process.  You need to know these too.
  3. For each of the 3 videos found HERE, take your own notes or add to the collaborative notes on the document.
  4. Discuss each video with each other so you all have a clear understanding of the points made.

    Friday next week there will be a test on Topic 7, with one question from each of topics 1,2,3 and opt D thrown in for good measure!  It is on the Verycross.  Yay!

Alkanes

Low reactivity of alkanes

Watch the following video and take your own notes.

 

Complete v Incomplete combustion

Complete combustion = excess oxygen and the products are CO2 and H2O
Incomplete combustion = limited oxygen and the products are CO and H2O
Write and balance the equations for the complete and incomplete combustion of methane, methanol, butane and butan-1-ol.

Reaction of alkanes with halogens

Find the equation for the reaction of methane with chlorine and the reaction of ethane with bromine.  Are these reactions fast or slow?
What happens if excess halogen is added?

Free radical mechanism

Watch the following video.  WARNING! – turn off the sound!
It breaks down the steps involved in the reaction between methane and chlorine.  Take note of the equations that occur at each of the 3 steps – initiation, propogation and termination.

Study these steps and try and memorise them.

What is homolytic fission?
Use the same pattern to now write the free radical mechanism for the reaction between ethane and bromine.

2 Organic Nomenclature

  1. This is a series of seven videos that covers the structures and naming of all the standard level compounds that you need.  View each video and take notes.
  2. Make a summary of the different types of functional group and how to name them.  This could take the form of a table.  Below is an example of a summary table prepared for another course.  Check the syllabus to make sure you include all the different types of compounds required by the IB.  HL has extra compounds mentioned in 20.1.1 and 20.1.2 of the syllabus.

  3. Try these problems once you have learnt the different functional groups.
  4. Need more practice?  This is a page with links to multiple sources for naming practice.
  5. Past paper multiple choice practice
