Top 10 Classroom Medics Science workshop Activities

10. COLIN THE COLON

A recent addition to our Classroom Casualty workshop, but already a firm (sorry, i couldnt resist) favourite. This is one of the more trickier activities where you can use an endoscope to examine inside Colin to find the tumours, ulcers and polyps.

9. SPRINT TIMER

This one always gets the competitive streak going. Principally this is just a short 15m sprint, but from the data collected we can calculate peak running speed, power output and break horsepower to see which house hold appliance or car you are!

8. LUNG AGE

Watch out smokers! We can tell you how old you lungs are. The worst pupil we ever had was 15 and had a lung age of 62! They had been smoking since the age of 12!

7. ELECTROCARDIOGRAM

Connecting youself to a computer with wires and crocodile clips has never been so much fun :-) You record and print the electrical signals coming from your heart with an ECG. The most common question asked is why a friend has different sized peaks (QRS). Its nothing to worry about, everyone is different!

6 .BATAK WALL

Used by professional athletes to test hand eye coordination and reactions, this is one of our most addictive activities…..well, with teachers it is. We have had PE and Science departments spend all of their break time in the hall trying to beat each others scores. No one has got close to Tom’s score of 68 in 30seconds.

5. BALL THROWING SPEED

One for the boys this one (not that girls can’t throw, it just more popular with boys). It can get very very competitive with lads throwing the same ball over and over againto try and beat each others scores. They all usually peak after the 5th or 6th go. One of the most memorable performances was a throw of 79mph by a 13yr old boy in year 9.

4. AGEING PHOTOGRAPHY

This was always gets groans of disgust as well as barrels of laughter. The sight of what smoking and sunlight does to your looks at the age of 72 always causes a stir, but for some reason obesity causes fits of laughing. I think this may show society has some way to go in tackling perceptions and attitudes towards obesity.

3. SULTAN THE GIANT

This is the lowest tech activity we have, but also one of the most popular! Basically a laminated piece of card that has Sultan the worlds tallest man printed on it along side many world records that rely on height and length. Pupils are always fascinated to see if they are as tall as the worlds biggest stack of doughnuts, daffodil or bunny hop!

2. STAN THE PATIENT SIMULATOR

Can we kill him? We get asked this about 30 times a day…. But we dont mind, because we can kill Stan in many ways to help explain how drugs and diseases affect the body and give pupils a greater understanding of how the body works. We now have pupils taking a diagnosis and examining evidence to see what is wrong with Stan and to see what the correct treatment is.

1. ANDY THE INJECTION ARM

Andy is Stan’s half brother, who is completely `armless and wont hurt anyone ;-) The opportunity to use a real needle and take some fake blood is the most popular activity we have. It is so popular that we have now started to cannulate Andy as pupils pick up the basics really quickly, they want somethig a little trickier! The youngest child to have a go was 4 years old at the Cheltenham Sciene Festival.

Top 6 Science Websites for Schools & Pupils

Tuesday, May 31st, 2011

Here are a few of our favourite science sites where you can find free resources or opportunities to bring in science talks and events to your school.

1. Science Live
This site is a great place to look for science presenters, shows and workshops for your school. You can search by region, theme and much more. There is also impartial reviews from teachers so you can see if they are any good. Check out the site and our 5 star reviews here. ScienceLive.net

2. Centre of the Cell
One of our recent finds, this site is brilliant if you are trying to find resources on cells and alternative / different careers in the health service. The website has games, interactive resources, case studies of patients, a cellpedia with explanations of everything to do with cells and curriculum links. You can also book to visit the Centre of the Cell centre in London! You can also follow them on twitter @CentreoftheCell

3. Cosmonline
If you pick up the free metro newspaper (available on buses and trains), you may read a feature called MetroCosm which explains lots of physics stories such as space missions and nuclear physics. I know, tough going if you are reading it on the way to work in the morning. However the guy that writes and draws the feature (@Ben_Gilliland ) does a fab job of making it easy with simply pictures and explanations. CosmOnline is his website version of the articles and stories as well as resources and competitions for schools.

We also love this site as we are going to be a guest blogger for the site with our Physiology in Film blogs! These will explain anything physiology based that appears in a film, such as when Daniel Craig is poisoned with Digoxin in James Bond – Casino Royale.

4. Science Oxford & Science Oxford Next
If you are based on Oxford and the surrounding areas, these websites are for you. The provide STEM resources as well as run a public science centre. Our favourite part of their website is the LifeLab which is a careers resource for pupils to use to find different jobs in their favourite STEM subjects. There are profiles of real scientists and information on what they do, how they got there and how much they earn. You can also follow them on twitter @scienceoxford

5. I’m a scientist get me out of here!

This site is great resource which runs events several times a year where pupils have the opportunity to ask questions directly to scientists via a video link up. It is a bit like the X-Factor for scientists! All you have to do is visit the site and register for the next event. There are some great videos explaining how it all works and what it is all about. Follow them on twitter @imascientist

6. Classroom MedicsCrMTVBlog

Ok, this is our own website and blog which you will probably already know about. BUT did you know we have a YouTube Channel called ClassroomMedicsTV ?

You can watch free videos on careers, science resources and post workshop activities for those that have used our workshops. We are constantly adding to the videos and have a lot of exciting plans for the next few months.

You will soon be able to download a PDF resource with lesson plans and links to videos from our main website. Keep an eye out for news on this! You can also leave us a comment below asking us to create a resource of video that explains something biological, medical,  health or career related and we will see what we can do. (our twitter address is @classroommedics )

Have we missed any great sites out? Let us know in the comments section below and don’t forget to like this blog on facebook and share using the twitter link below!

How do nicotine patches work?

Saturday, March 12th, 2011

Nicotine is a drug found in cigarettes. When smoke is inhaled, nicotine is transferred into the blood stream and is transported to the brain where it has its effect. The problem with nicotine is that it is addictive and it is the chemical that makes it difficult to give up the ‘cancer sticks’. So how can sticking a nicotine patch on your arm help give up smoking?

Well, the patch has a reservoir of nicotine placed between a impermeable backing layer and a permeable membrane on the skin side that will let the nicotine through. Your skin is normally a protective layer that does not let much through, except lipid soluble (fat loving) molecules just like nicotine. As they penetrate the skin they can be taken up by the small blood vessels under the skin called capillaries. Over 16-24 hours nicotine is drip fed into the blood, all be it at a much lower dose than the short sharp hit from a cigarette.

BENEFITS OF USING A NICOTINE PATCH
- No carbon monoxide poisoning
- No Tar build up in the lungs
- Less exposure to carcinogens (cancer causing chemicals)

After a cigarette, nicotine levels peak and die off over 20-30 minutes, so at night time, nicotine levels drop to virtually nothing. With patches some users experience nightmares as there is a constant low level of nicotine in the blood for longer, which has an adverse effect on the brain during sleep.

It is really important that if you are using the nicotine patches that you do not smoke at the same time as there is a risk of a nicotine overdose!!! The effects of an overdose include nausea, cold sweats, headaches, dizziness, confusion, racing heart beat, seizures and even death! We will go into this in more detail in the next blog, which is all about how nicotine works on the brain to have its effects and why it is so addictive!

Remember, if you have any comments or ideas about what we should blog about, let us know in the comments below (that rhymes!).

Want to become a doctor? – a quick guide

Wednesday, March 2nd, 2011

If you have been watching the excellent Junior Doctors on BBC3 you may have thought what are all the different grades of doctor and who does what and how do you get there? Well I am going to explain all!

PART 1 – Medical Degree
To become a doctor you need to firstly complete a medical degree at university. This takes 5 years if you enter straight from 6th form or college. During the 5 years you learn about physiology (the body) pathology (disease) pharmacology (drugs), chemistry, physics (yes, physics! This is needed for radiography, MRI scans etc). Lots of medical schools use problem based learning where students are given a scenario about a patient and have to diagnose them from the evidence they are given. It’s a bit like House but without the real patient! You also do placements to get practical experience usually after a year or so. In the final year you apply for your Foundation years as a junior doctor

PART 2 – Foundation Training
After your medical degree you are now a junior doctor and have to apply for placements for your foundation programme which takes two years to complete. First year doctors are called and F1s and second years F2s. If you watch Holby City Penny & Oliver Valentine are F2s and Frieda Petrenko is an F1. These roles used to be the Pre-Registration House Officer (F1) and the Senior House Officer (F2). F1 doctors spend at least 3 months on a surgical ward and at least 3 months on a general medicine ward. The F2s have three 4 month placements where they can go to specialist units and general practice (a GP) before deciding what they want to specialise in. During these two years the junior doctors will have to pass what are called competencies which are specific skills they must learn. Without them they cannot continue and have to repeat placements. YOU ALSO START TO GET PAID! The starting salary is currently £22,412 a year for an F1 and £27,798 for an F2.

PART 3 – Run-through Training
Once you have completed your Foundation Training you can specialise in what is called Run-through Training and again you have to apply for places in your specialism. To become a GP doctor this takes 3 years of additional training. In specialist areas such as cardiology, neurology etc, this will take between 5 – 7 years of training. You can also apply for shorter one year specialism posts, but there is no training after 2 years if this option is taken. The basic starting salary on RT Training is £29,705 and this can increase if you work more than 40 hours a week and outside the 7am-7pm time frame. After your RT training you can then become a consultant and can earn between £70,504 and £100,446 per year! At this point you will be around 30-32 years old, so it takes a long time to get to this point! GPs earn around £53,781 to £81,158 although you can be self employed and set your own salary.

So there you go. After 7 years of training you are let loose on patients and then after another 3-7 years you can start to earn the big money as a GP or consultant! However that is not what being a doctor is all about. If you want to become a doctor you have to want to work hard, help people and be able to deal with very difficult situations quickly and efficiently. After all, the decisions you make could be the difference between life and death.

Tips for Revision – A parents guide.

This is a Computer Fundamentals class taking a...

Have your kids got exams coming up? Are you more stressed than they are? Don’t know how to help? Well fear not! Take a look at our top tips for parents to help you and your kids get through the exam season.
1. Give them their own space to revise in.
Having somewhere quiet and tidy for them to study in is key for success. If possible, set aside a room, or table for them to study at. This should be theirs for the duration of their revision.
2. When should revision start?
Revision for GCSEs and A-levels should start around February / March time. At the start this shouldn’t been too major, just reading notes or work for 30 minutes or so on an evening. We have designed a revision planner to help you and your kids revise you can download it by clicking on the following link REVISION PLANNER
I used to split my day into morning, afternoon and evening sessions and then revise for two of these a day. Each part of the day would be 3 hours long and was split into the smaller 30-50 minute sections. I would have at least an hours break doing something else between a morning and afternoon and evening sessions. It is key you have mini breaks as their brain needs a rest to absorb the info you have given it….this doesn’t mean an hours break, just a short break or 10-15minutes. If they are feeling HARD CORE they may even do some revision in all three sessions!
3. Keep the house as quiet as possible when they are revising
Ask your child when they are going to revise so you can keep the house as quiet as possible and try not to keep on disturbing them with drinks and snacks! They are only studying for short blocks and wont starve or dehydrate in that time!
4. Keep an eye on music, mobile phone & computer use during revision
Listening to music and using the computer to revise are not advisable. The brain has too many distractions if music is playing, the computer is on and revision is trying to take place. The best way for their brain to soak up all that revision is in golden silence! If they say it helps them concentrate….well I am sorry that usually isn’t the case as they (and I know I did) usually end up
singing along and changing tracks. Revision also goes a lot quicker with out distractions.
5. Help them plan their revision
Sit down with your child and our REVISION PLANNER to help them plan. Make a list of what they think they are good at and what they need help with. Keep subjects and topics together in one session and don’t switch between too many subjects in one day. Being organised is key. If they go to any clubs try and keep these in the plan as they will be a welcome distraction to revision!
6. Keep an eye on study groups
Just like music and computers, study groups may be suggested and seem like a good idea, and they can be. However it is not uncommon for revision to turn into a chat about other things. They are good for testing each other near the end of revision periods, but not general revision.
7. Sleep is important
Burning the mid night oil is not a good idea. Their brain needs time to re-wire itself and process all of the information that has been thrown at it in the day. 8 hours sleep at least is a must!
8. Don’t tidy their desk / space
If you think their revision area is a bomb site….DONT TIDY IT UP! Your child may have some system of piling notes together into topics. Maybe suggest that they tidy up at the end of the day and start with a fresh tidy desk in the morning.
9. Give them a treat / bribe at the end of day or week, or for exam results
Some parents agree to give rewards or treats, (although the rewards of good exam results leading to better jobs and future should be enough) a little encouragement can be useful. Agree these at the start and how they will be monitored. You may let them use the PlayStation, go on the computer, or take them to the cinema at the end of the week. I have even seen parents put prices on grades achieved! (eg: £20 for an A, £10 B, £5 for a C) Bribery is always useful!
10. Help them revise where possible
Ask them if they need any help with revision. You could time revision periods, mark multiple choice questions, read their work to check for spelling and grammar. Don’t do this all the time, but remind them every now and then that you are their to help if they need it, even if it is just for them to talk about a subject you don’t even understand! By speaking aloud they may all of a sudden understand something they didn’t before! Our brains work in very weird ways!
11. Trust them!!
Trust is really important. If you can help them plan you can see what they are going to do. Don’t keep tabs on them all the time, but ask how their revision on today’s topic went.
12. Buy them an exam pencil case
An exam pencil case should be see through and contain the following: 3 x HB pencils, rubber, pencil sharpener, 5 x black ball point pens, 5 x blue ball point pens, ruler, protractor, calculator. Don’t use fountain pens, they leak, smudge and can be difficult to read if written with a speed a the end of an exam.
