Good afternoon,

Sorry I’m not in today, I’m moving house! Some of you have now finished your BTEC work and should be congratulated on your efforts and some of you still have some things to do, which we shall tackle when I’m back on Thursday.

Today’s lesson:

You will need to produce a plan for an experiment and present it as a scientific report. We will carry out the practical next lesson and will then come back to the IT rooms to write it up.

You need to plan a piece of practical work to investigate how cooking peppers changes the amount of vitamin C they have in them.

You will need to complete a report and answer the following questions:

Title

Introduction

-          What are you investigating?

-          What do you think will happen?

Background science

-          What is vitamin C and why is it important?

-          What happens to vitamin C when it is cooked?

-          What is DC-PIP and how do you use it to test for vitamin C?

Method

-          Plan an experiment to answer the question. You will have access to beakers, Bunsens and heating apparatus, water, plenty of peppers (your vegetable), DC PIP, Pasteur pipettes, Pestles and Mortars and anything else sensible that you would like.

Risk assessment

-          What dangers are there? What will you do to avoid them?

Results table

-          Draw a results table for your investigation

EM Spectrum

Learning objectives for today:

1.Be able to identify different parts of the electromagnetic spectrum.

2.Be able to describe features of the electromagnetic spectrum.

Now Complete the EM spectrum worksheet using the websites below:

Pass and Merit Level Work

Good morning,

The Pass Level Work...

Ensure you have completed your article on "how to save the Earth". This must include sections on acid rain, global warming, quarrying, waste disposal/landfill and deforestation. You should look at previous posts for help and the questions to answer

The Merit Level Work....

Find the proforma in the shared area:
shared area --> science --> Ms Elias --> 10ScB1 Work --> Human effects....

Your article was about the human impact on the environment and you must now compare two of these to the "natural changes to the environment" that we looked at before - e.g. earthquakes and volcanoes.
Discuss which has the greatest impact on the environment. To help you do this you could make a table covering these points, or just write about them:

For each effect on the environment answer these questions:

• What damage has it caused to people? 
• What damage has it caused to animals and plants? 
• What are the long term effects on the land? 
• What are the long term effects on the air?

You must write about earthquakes, volcanoes and two from acid rain, global warming, quarrying, waste disposal/landfill and deforestation

Email everything you have written to me at the end of the lesson lel@cheney.oxon.sch.uk so I can look over the holidays. 

Deforestation

Once you have finished the questions on quarrying. Watch the video here http://www.youtube.com/watch?v=7KSMFIGQ2nI&feature=related and then answer the following questions

Part 4: Deforestation

1. What is deforestation?
2. Why does deforestation occur?
3. What harm does deforestation cause to the environment and to animals/birds/plants?
4. What can be done to try and reduce the effects of deforestation?

Place these answers in the document we have been working on. Include pictures.

Part 3: Quarrying

Part 3: Quarrying

What is quarrying?

Why do we do it?

What harm does it cause to the environment?

What can be done to try to reduce the effects?

Use these to write your article:

Task: Write an article with the title ‘How to save the Earth’.
Part 1: Global warming

What is global warming?

What causes it?

Why is it such a problem?

What can be do to try and reduce it?

Cover work 06/02/14

Good afternoon,

I'm sorry I'm not in today, I'm on a trip with my year 11 students.

Today you need to finish off the work on conduction, convection and radiation (see previous blog post) and then you need to complete the sheets in your red book that are related on pages 82, 83, 78 and 79. If you don't have your red book then you need to ask the cover teacher if you can go and copy someone else's.

When this is all done you can watch these revision videos:

Have fun without me!

Conduction, Convection and Radiation

Good morning,

The lesson objectives for today are:

1. to be able to list forms of energy that can be stored
2. to be able to describe conduction and where it occurs
3. to be able to describe convection and where it occurs
4. to be able to describe radiation and where it occurs

Grab a post it note and grade yourself from 1-5 on each of the objectives (5 being "I'm amazing"). Stick this on your screen edge


Your research/reading task:

• using the websites below produce a diagram of convection. Describe what convection is and where it happens. 
• repeat this for conduction and radiation.

Revision work 1

Good morning,

Today you will be revising the revision that we have done in the past two weeks. This is important as we only memorise information by going over it more than once.

By the end of this lesson you should be able to:

1. identify atoms, elements and compounds
2. draw atoms correctly showing their inner workings
3. use terms alkali, acid and pH with confidence
4. answer questions on acid/metal reactions

To do this you will need to find a partner, a pen and two worksheet packs each. You will need your book to help you.

Complete the worksheets. Everytime you complete one double side you should bring it to me for marking/checking. If you have any mistakes you should correct these before you move on. 

1 completed and corrected worksheet pack = 1 achievement point

Enjoy,

Ms Elias

Cover Work - 06/01/2014

Good morning Y10.

I'm sorry I'm not in today - my chest infection is back with a vengeance.

I would like you to start work on revision for your exam next month. We have about 10 lessons to go through the Chemistry we've learnt and learn some new things, plus you'll be doing revision with Miss Chandarana too.

Today you're going to be revising atoms, elements and bonding.

Work through the web link below, completing the tasks and reading the revision material.

1. http://www.bbc.co.uk/schools/gcsebitesize/science/aqa/fundamentals/

carry out the revision by making notes on paper, do the activities and then take the tests

2. http://www.bbc.co.uk/schools/gcsebitesize/science/add_aqa/bonding/

just the parts on ionic and covalent bonding...

3. Complete the worksheets that the cover teacher has. You should hand these in at the end, with your NAME ON, and someone will need to volunteer to take them to the technicians in W11.


Have fun.
Be respectful.
See you soon.
