What can Profiling do for a Studnet’s Future Career?
This short video I recorded at the Irish Times Higher Options Conference in RDS explains why profiling is so important for Students early in their education life - You can pursue the Career you were born to do!
DNA extraction of a kiwi plant in The Homework Club kitchen
Lesson devised by Graham Huges who has taught maths, science, computers and biology at The Homework Club for the last two years.
Graham Hughes is studying a PhD in Bioinformatics at UCD. He is interested in Science, particularly biology and believes with the correct approach, science can be made accessible and enjoyable to all students. Graham also works on computer techniques to make students more motivated to do well in mathematics.
DNA, DNA come out and play...
If you were to zoom in closely on a piece of your skin, you would see it is made up of millions of cells. If you were to zoom in on a cell you would see it is made up of smaller organelles. If you were to zoom in on certain organelles you would see that they contain DNA. DNA stands for DeoxyriboNucleic Acid and is made up of long strands of the letters A,T,G and C. The arrangement of all these letters in your DNA is the ‘recipe’ for you.
All animals and plants have DNA in their cells. By using household materials we managed to extract and view some of the DNA in a kiwi! Even though you cannot even see kiwi cells with the naked eye, with the tricks of the trade, we can gather enough DNA to make it easily visible. All it takes is a little chemistry...
Firstly we need to make an ‘extraction buffer’. This involved putting water in a plastic cup, adding 2 small sachets of salt and putting 2 squirts of hand soap, giving it a good mix. The soap breaks up the fatty kiwi cell membranes and the salt makes the DNA clump together.
Measure the speed of light using marshmallows
This lesson is developed by Conor Coyle. Originally from Monaghan Conor moved to Dublin for university where he studied Applied Physics for four years. After this he spent a year in Chongqing China teaching, my itchy feet didn't stop there, after China Conor moved to France where he worked as a waiter and studied French part-time. He then returned to Dublin where he is now a final year postgraduate researcher working on low temperature plasma physics for biomedical applications. Conor likes cooking and make a mean chilli con carne. (which he hasn't made for me yet! Naoisé)
Items needed for this experiment : Marshmallows, Plate, Microwave, ruler, marker, brain engaged
What you need to do:
- Cover the plate in marshmallows, remove the turntable from the microwave and cook for 45-60 seconds.
- Take the marshmallows out and note the melted spots on the marshmallows. Using ruler measure the distance between the spots.
Learning from Mock Exams
The snow before Christmas had a knock on effect for many exam students this year. Students sat mock exams later than normal without getting a chance to finish any more of the course work. Everyone has anxiously awaited results and feedback. At The Homework Club we believe evaluation is vital to success. The Mock results don’t have to set what you will get in June. Included are some of the top tips we go through for our own students. The mocks are a test run! They test our endurance.
If you had a good mocks - you should be always be careful. Were you just lucky with the paper? are you likely to get the same questions in June? If yes, your on the road to success.
If you had a bad mocks - Don’t despair. Above all else stay confident. Always aim for the stars and you will reach success. Find your mistakes and learn from the experience. It's not the end of the world.
There are 8 main factors that effect exam performance
Subject Knowledge
Your Exam History
Exam Preparation
Exam Practice
Experience of the Subject
Writing Skills
Use of Time
Attitude and Approach
1st classes written on the table
Our new experiment .. whats happens if you let the students write directly on the tables?
This idea steams from coffee time at the Southampton Oceanography Centre while I was studying for my PhD. Physics nerds from the research section would gather around for morning coffee break and invariably talk about the latest scientific dilemmas. One morning someone brought a white board marker and wrote directly on the table.. a brilliant idea had begun.
The great advantage of this practise is that everyone is involved. If left for 5 minutes on their own students will always gravitate towards the white boards and the coloured markers, “we never get to write on them in school”. This shows how little its takes to excite a student!
