This is just to inform you about the fact that there are several free public talks and events relating to astronomy in Oxford in the next few months which look interesting.
Finding the Big Bang

27^th Apr 2012, 5:00pm - 6:00pm

Astrophysics are hosting a public lecture about the big bang and the expanding universe. More information can be found here: http://www2.physics.ox.ac.uk/events/2012/04/27/public-lecture-%E2%80%98finding-the-big-bang%E2%80%99-professor-p-james-peebles.

Monday 28 May at 6pm to 7pm
Just A Black Dot?
On 5 June 2012, Venus will appear as a perfect black dot crossing the face of the Sun. This is known as a transit and is a very rare event to view from Earth. Only Venus and Mercury are placed to do this, and only then when there is an exact alignment of orbits. Though occurring in pairs a few years apart, this is generally a 'once-in-a-lifetime' experience.

The talk will look at the historical importance and Oxford's connections, the details of this year's transit and the modern relevance of making accurate transit observations.

Speaker: Charles Barclay, Director, Blackett Observatory, Marlborough College and Associate Fellow, Green Templeton College.

Exploring the Distant Universe

Saturday 2 June 2012 at 2pm
A public lecture for the family.
Over the next ten years our understanding of the Universe will be transformed by a new generation of both space and ground-based telescopes.

The 20-year-old Hubble Space Telescope will be replaced by the James Webb Space Telescope (JWST). Discover how the JWST, with a mirror five times larger than Hubble, will allow us to identify not only the most distant stars and galaxies in the Universe, but also find planets approaching the size of the Earth orbiting other stars.
Find out how a new class of ground-based 'Extremely Large Telescopes' (ELTs) will complement JWST with their ability to obtain exquisitely detailed observations of individual objects such as distant galaxies.

Speaker: Stephen Wilkins, Oxford Astrophysics.

Practice questions

Here is the link for the practice questions for the resit ISA. The practical will take place on Tuesday 20th March after school , and the exam on Friday in lessons. Please bring your answers to the questions below to the ISA on Tuesday. No answers = no repeating the ISA.

ISA tips 2013

Here is the checklist and the uncertainties guide

AQA world ISA guide to calculating uncertainty

Is the variable independent (you change it) or dependent (several values and a mean)?
For independent variable, uncertainty is + or – smallest measurement on instrument
For dependent, plus or minus half the range,
Percentage uncertainty independent is precision / value then x 100%
Percentage uncertainty dependent is 0.5 x range / mean then x 100%
For percentage uncertainty of a calculated value, find the total percentage uncertainty by adding the parts of each calculation together
