FRiday 10th December 2010

Hurrahhhhh ..all the work for the prelims completed ..despite the snow !!!!! :-)

So into revision mode next cycle once we have done more of the questions you were working on in class today.

Don't forget to complete the homework sheet I gave you for Tuesday.

You are working so hard and so well.....you all deserve a pat on the back..or maybe an orange ...we shall see

Have a good weekend

Hi

Great experiments today....they both worked !!!! well for some people blowing a fuse in the power pack did cause a wee problem....

Don't forget fuse sizes and the difference between ac and dc.

Next lesson we shall look at what ac and dc look like on the oscilloscope and how we can compare the peak ac voltage with dc.

Don't forget to do your homework which is due on Friday..no late submissions...

Hope the journey home wasn't too cold.

Come and talk to me if you have any problems.

Mrs M :-)

Friday 3rd December 2010

In class we went over the questions you did for homework...please check your first class email for details.

New topic started....and we did pages 1 to 4 and page 7 plus questions 3,4 and 9 on page 14

Homework is the handout sheets I gave you....please do not give me the answers on the handout sheet....do them properly on paper. Don't forget to show all your working.

This homework is due on Friday 10th December...no late hand ins please

Have a good weekend

Mrs M :-)

Wednesday 1st December 2010

Well done to those of you who got in to school.

For those of you who missed class here is what we did...please do the work - solutions will be issued next class.

Read the theory of potential dividers - page 31.... ...they are also known as voltage dividers. Check your data book the equation is in there - page 3 second column ....
The bigger the resistor the bigger the chunk of voltage that you will measure across it.
Try the example on page 33 the answer is 8 V.

For next lesson ...
1. Complete the questions on pages 28 to 30 (nos 1 to 15 - your homework for today (Wednesday) was nos 1 to 7).
2. Do the questions on page 34 / 35

Both of the above are to be completed for Friday 3rd December.

Keep safe and warm

Mrs M :-)

Friday 26th November 2010

Resistance in parallel.....not quite as straight forward as resistance in series....take care when you are doing these questions....so easy to forget the last step.

Some examples will have helped...

You handled the experiments well...we shall talk more about potential dividers next lesson...

Homework for next lesson..1st December is page 28 /29 nos 1 to 7

Have a good weekend

Mrs M :-)

Wednesday 24th November 2010

NAB ..well done to those who passed and 'we will work together' to those who failed.

Experiment to find resistance and series and parallel went well....more on how to calculate it in parallel next lesson.

Homework for Friday is page 26 nos 1,2,5,8,9

Any questions you know where to come

Mrs M :-)

Monday 22nd November 2010

NAB over and done with for most of you.....date set for those who did not sit as Thursday 2nd December - lunch cards available....as the test will start at 12.45

Brief review of what we had done to date in electricity. I was very impressed with the amount you remembered. Well done...

Homework for next lesson (Wednesday) is to make sure you have all the notes up to and including page 21 copied up and to do the following questions....
page 7 nos 4,6,8
page 18 nos 1,2,3
page 22 nos 2,4,6

NAB results available from me in the morning

Mrs M :-)

Wednesday 17th November 2010

Apologies for doing the feedback of the test in such a strange order....but either way you get the same result form the test - areas of strength and weakness.....

As usual I am happy to answer any questions...so please do !!!!

Remember NAB is being done in the next lesson....which is Monday 22nd ..so keep revising..keep asking questions....and of course good luck.


Must add that I am sooooo proud of this class.....you are all doing so much more than last session and it is starting to show...

Mrs M :-)

Thursday 11th November 2010

Very short lesson ..but we still managed to answer some questions.

Test is next lesson...please bring with you the YELLOW notes - topic 1 of electricity to class on the same day as the test.

Keep revising ..cake and oranges at stake here

Any queries please come and see me

Mrs M :-)

Monday 8th November 2010

Revision is the order of the day.....so it was just a case of selecting a topic and working on it.

I was very impressed..you all did just that.

Please repeat this exercise at home...in class revision is not sufficient.

If you want to borrow a question book then please come and collect one.

There will be time for a little revision on Thursday and then the test is Monday.

Any questions...please come and ask.

Mrs M :-)

Thursday 4th November 2010

Yes heads down and good work......conservation of Energy means that heat in equals heat out.

Use the solutions I gave you to practise other questions.

Now revision.....homework for next lesson (Monday) is to look at topic 1 and 2 using the revision sheets and complete the LOs.

Remember cake / oranges if you all do well

Mrs M :-)

2nd November 2010

So ....heat I think we have it under control...well done :-)

Two equations..two very different times when we use them.

Don't forget that we also have to remember that the heat given out by a hotter material will equal the heat taken in by the colder material....

Here are the plans for the next few lessons:

4/11/10 - Complete the topic; start revision
8/11/10 - Revision
11/11/10 - Remembrance day and revision
15/11/10 - Test
17/11/10 - go over test ; start new work
22/11/10 - Unit 1 NAB
24/11/10 - go over NAB and new work.

So start NOW !!!! Revision of all of unit 1 - 4 pink booklets.

Bring in any questions you need to ask.

Good luck..I have every faith in you

Mrs M :-)

28th October 2010

I hope you feel that you understand the difference between.....

1. E = mass x specific heat capacity x change in temperature

2. E = mass x latent heat

They are two very different things..(1) applies when the temperature is changing and (2) applies when the state is changing.

Homework uses only equation number (1)..and that is page 5 questions 3,4,5,6,8 and 9 due on 2nd November.

Remember what I told you..we are very close to having a big test..so start looking back at unit 1 now....all of it will be tested this time.

Any queries you know where to come.

Mrs M :-)

26th October 2010

A bit late in starting due to the assembly and House assembly. However, we did manage to get quite a lot of work done.

The difference between heat (energy) and temperature (a measure of how hot or cold something is ) was established.

We then went on to find the specific heat capacity of water - and it was higher than we expected due to the heat loss to the surroundings.

The equation for the day is E = c x m x change in temperature.

More experiments next lesson.

Assessment on the horizon covering all of Unit 1 so can I suggest you start revising now.

Any questions please ask

Mrs M :-)

Thursday 14th October

Topic completed....in school, but at home you should now be doing some serious revision..there will be a test on the whole unit towards the end of November so you should start NOW looking over this topic and the previous ones. (All the topics in this unit have a pink front cover and so far you will have 3 pink booklets).

Don't forget to do all the efficiency questions....for Tuesday 26th october.

I hope you all have a great break.

Bye for now

Mrs M :-)

Monday 11th October

I think you have grasped the idea of reaction time and time to stop.....

Potential energy to Kinetic energy took up the remainder of the day....don't forget that if you ignore air resistance then they will fall to earth at the same time no matter the mass. In real life friction does have an impact (as we showed in our experiment).

Give your best attempt at questions 1 and 2 on page 29 - due on Thursday... see me if you have any queries.

Mrs M :-)

Thursday 7th October 2010

A different way to go over homework...but I hope it was fun and that importantly you got the correct message from the answers. Use the other questions as a revision tool. We won't do that every time....but now and again makes it a special treat. Sorry about the ginger bread men..oranges next time I promise.

Remember your total stopping distance is a mixture of the distance you travel while reacting plus the distance you cover as you are braking to a stop.

Homework will help you with this....so for Monday page 21 - Section called questions nos 1 to 4

Great work as always....everyone bring their homework on Monday

Mrs M :-)

Tuesday 5th October

FANTASTIC!!!!! AMAZING !!!!! WELL DONE !!!!!

Your confidence has come on so much. You are happy with so many ideas / concepts that last year you were too worried to attempt.

I am SO pleased for you :-)

Now we know....Kinetic Energy, Work Done energy, Gravitational Potential Energy and Power..

In class we were working on the following questions which you will finish for Thursday...usual drill..no excuses..need help then come and ask.

The questions are
p12 nos 4,5,6
p14 nos 6 to 10
p 16 nos 4,5
p21 (Kinetic Energy Questions) nos 2 and 4

Keep going :-)

Mrs M :-)

Thursday 30th September

What did YOU get from the test? How are YOU going to use the test to help YOU prepare for future assessments. Make a list for YOU!!!

In class we looked at 3 equations all related to energy....Work Done; Power ; Gravitational Potential Energy.

Please make sure that you are familiar with the equations, symbols and units.

Apologies for the mix up with the homework...but let's all get it right for Tuesday. :-)

Have a good weekend

Mrs M :-)

Tuesday 28th September

I know tests are never fun....but they are important as they show you where you are needing to do a little more work.

Results will be available from tomorrow morning.

Don't forget the homework that I asked you to do for Friday...remember layout of the questions are the key to your success.

Any queries please see me on Wednesday or Thursday....in school from 7.30am and won't be leaving before 5.30 / 6...

Mrs M :-)

Friday 24th September

I hope that going over the homework the way we did has given you some useful tips for the test on Tuesday. Don't forget...you can always come and see me on Monday, but please note I will not be around at the end of the school day.

Newton's Third law and the implications for collisions were our main focus today.

I hope that you can clearly see the importance of laying out the momentum conservation problems carefully.

Learn the statement of conservation of momentum....don't forget the words..'in the absence of any resultant external forces'.

Homework for Friday 1st October is pages 9 / 10 nos 2,6,8,10 and 11

Have a good weekend....don't forget to revise regularly and do lots of examples.

Mrs M :-)

Tuesday 21st September

Applying Newton's third law gave us the conservation of momentum. The experiments showed that momentum is conserved if there are no external forces (like friction or someone giving it a push !)

There is a formal definition you need to learn but more of that next lesson.

For Friday you must take a long hard look at your notes - the test is on Tuesday......use the LOs - can you colour them green / tick them off. Don't forget to bring in any queries and either see me before class on Friday or ask during class.

No formal homework but revision is the order of the day. Use the questions in your notes.....don't just look at them try them again.

Good luck and happy revising

Mrs M :-)

Thursday 16th September

Going over homework in this way I hope helps you to 'see' where you can avoid making erorrs.

I know that writing down data and equations may seem tiresome, but it is important and could save you marks!!!

This way you can avoid needless errors.

So don't take short cuts follow the rules :-)

Thanks to Ollie we 'saw' the balanced equal and opposite forces that led us to Newton's 3rd Law....It is important that you learn this definition (just as you have learned Newton 1 and Newton 2....you have...haven't you ?)

Identifying paired forces can be tricky but you were getting the hang of it by the last few examples. Just remember you only look at one point....not every where at once.

So what does Newton's Third law also mean.....momentum and trolleys colliding. This is what we will do next time.

Don't forget your homework and start revising for the test....

Great lesson ..well done

Mrs M :-)

Tuesday 14th September

A good 'catch up class'. Many of you missed the last lesson due to the Chemistry trip but I hope that you are all now happy with the idea that:
horizontal velocity of a projectile is constant
vertical velocity of a projectile is uniform acceleration (the word uniform is very important).
all objects (no matter what their mass) will fall to earth with the same uniform acceleration - this is g = 10 m/s^2 = 10 N/kg

Homework for Thursday 16th - complete questions 1 to 5 on page 31

Homework for Tuesday 21st - complete the handout homework

Test on this topic only - Tuesday 28th September.

Good work....don't forget to do your homework. I am off to mark your homework.

Don't forget to ask questions if you need help.

Mrs M :-)

9th September 2010

Those in the class revised vectors and did work on acceleration...sorry you missed that.

I hope you enjoyed Enterprise Day and the Geography Field Trip.

Have a good weekend.

Don't forget the homework due on Tuesday.

Mrs M :-)

Tuesday 7th September

Sorry I was not in class but Mr L tells me that you worked extremely well for him - thank you so much for that.

With Mr L you :
measured 'g' - you must tell me if you got good results or not.....
began your study of projectiles - looked at bodies of different masses falling and the pulsed water drop....

Please do not worry if you missed class due to the Chemistry trip - I will make sure you catch up....

Enjoy Thursday's Enterprise event - if you are attending it - and I will see some of you in class.

Don't forget homework for Day 7 - 14th September.

Mrs M :-)

Vectors..are they fun - 3rd September 2010

Well..delighted to be back blogging to you all for a second year.

I do believe that you have 'cracked' acceleration and I was very impressed with the way that you tackled the vector addition questions I set you in class....we will keep working on this until you are 100% happy :-)

Don't forget homework ...set for 14th September ...a first for me to give you so long to do the work..but lots of exciting things happening in between then and now...and the homework is to complete the acceleration questions on page 25....nos 7 to 15

Enjoy the fireworks on Sunday if you are going...forecast looks good and I will see some of you on Thursday.

Mrs M :-)

Welcome to Session 2010 /2011

I hope you enjoy using this blog.

More after each class.
