Kingsmedia Podcasts: Recent Episodes
Mr Summers
These Podcasts include Physics and science related content, reviews and input from the Kingsmedia student team. They will also include careers related content including interviews with Kingsmead students, University students and people actually doing the jobs our students might be interested in.
This is our first Kingsmedia book review by Cara and Sarah. I was a little scared just listening to the review but this might be your next favourite book. If you have a book you would like to tell other people about, talk to Mr Summers or Mrs Russell.
"If you like horror and you like fantasy, it's a really good blend of both them" is part of the summary given by our reviewers.
Enjoy.
We also want written reviews for the KNG-2020 magazine and photos of you reading. Send articles and photos to kingsmedia@kingsmeadschool.net
This is a 17 mark question covering the following: converting GW (gigawatts) to W (watts); calculating a percentage; what a 'low-carbon' source is; the National Grid 6 marker and a 5 mark, two stage calculation.
This is the one about a water distiller and includes the use of the equation for specific heat capacity; interpreting a heating graph as water is boiled; deciding what might happen if the auto-off switch fails; knowing the colours of the wires in a plug; the purpose of the earth wire and recall and use of the equation linking power, current and resistance.
This is the one about sodium street lamps and covers isotopes, energy levels in the atom, atomic structure, changes of state and power. There are other podcasts for Q1&2, Q4 and Q5.
In this Podcast I run through the first two questions on the Higher Tier Specimen paper 1, 2018 Set 2. These two questions were common to both the Higher and Foundation papers, being questions 6 and 7 on the Foundation. Make notes as you listen, pause and look at what you got for each part of the question. There are some key phrases that we look for as examiners and some of these questions are classics that crop up all of the time.
Q1 is the one about how length affects the resistance of a wire and includes how to use voltmeters and ammeters, what 'precise' means, why we calculate a mean average, the recall and use of the equation V=IR and reading a graph.
Q2 is the one about the radioactive decay of radium-226 and involves finding half-life, understanding why radioactivity is hazardous and the properties of alpha, beta and gamma radiation.
With restrictions to face to face meetings this year, we are looking at new ways of giving you information about your next steps in education here at Kingsmead. In this presentation I outline the topics that you will study in A level Physics, why it is such a great subject to study and what recent students have gone on to study. We have three fully qualified A level Physics teachers who are passionate about their subject. Have a listen and decide whether this subject is for you.
In this Podcast I go over 4 of the 21 equations that you need to learn for GCSE Physics. You must be able to write these down correctly and use them to solve problems. Knowing what the letters mean and how they arranged in the equations will really help your understanding and ability to answer exam questions.
I will go over the equations for work done, power and the two ways of writing the efficiency equation. These equations are used to describe key areas of physics and lay the foundations for the work that we will do later in the electricity, particle model, atomic structure, forces, electromagnetism and, if you are doing the Triple Physics course, space as well. Understanding energy really is that important.
If you are listening to this on the school Blended Learning Platform, please complete the short survey afterwards so that I can produce more content to support our learning.

This is the second Examiner challenge question aimed at stretching you to achieve level 7-9 in science. Some of you are opting in to these challenges and doing the questions online as Microsoft Quizzes. When you have, these have been marked and the question and mark scheme has been sent to you, along with this Podcast. Here it is for everyone to listen to. Hopefully it will be useful, although it is even better if you have a go at the question first. At the moment I am sending these out as flexible tasks in Show My Homework so look out for them. They go out on a Monday and I mark them on and produce the Podcasts on Saturday morning.
This is the first Podcast going over challenging questions that I have been setting weekly. This first one is based on an AQA Paper 2 question on stopping distance. You really need to have a go at the question before listening, but if you haven't done it you might still learn something here to help your understanding. This was deliberately challenging and aimed at those students aspiring to levels 7-9 at GCSE.
In this podcast, I talk about how to find the density of regular and irregular objects. A couple of extra points:
1. The dependent variables are always the ones you are measuring. In the experiment to find the density of an irregular object, this is the volume of displaced water. I talk about the displacement, or Eureka, can but this can also be done directly in a measuring cylinder holding a known amount of water which is your starting point. If it is big enough to allow the object to be put into the cylinder, the water will rise to a new level and the difference between that and the original level will be the volume of the object.
2. The 'independent variable' is the one you change. In this experiment it is the object.
3. You measure the mass using a top-pan balance. Examiners will accept 'mass balance' or even 'scales' but not scale.
