UK based Physics teacher providing high quality resources. Specialising in AQA GCSE 9-1 and IB Physics specifications.

#### Velocity-Time Graphs

(0)
Designed for the AQA GCSE 9-1 specification. I teach the topic over two lessons to unsure a full understanding. Lesson objectives include Understand how to measure velocity changes. Understand what a horizontal line on a velocity-time graph tells you. Understand how to use a velocity-time graph to work out whether an object is accelerating or decelerating. Understand what the area under a velocity-time graph tells you (Higher) Students will be assessed in the following ways Plot a velocity-time graph from given data Calculate the acceleration from the gradient of a velocity-time graph Describe the motion at various stages of a velocity time graph Calculate the area under the graph for simple graphs. Calculate the total distance travelled for complex graphs. Calculate the distance travelled by counting squares I have included a number of worksheets that accompany the PowerPoint. Images that are not my own are referenced in the resource.

#### Newton's Third Law

(5)
This was created using some of the great resources on TES and put in a format that I feel is manageable for my classes. Credit must go to cmsciguy https://www.tes.com/teaching-resource/newton-s-laws-6203395 for some of the examples used. I have created a worksheet to go with this as I find my students like to have something to refer to that is of the same nature as the lesson I am delivering.

#### Electromagnetic Spectrum

(7)
Designed for the new AQA 9-1 specification covers the following objectives, - Identify the position of EM waves in the spectrum in order of wavelength and frequency. - State that all EM waves travel at the same speed in a vacuum. - Describe the relationship between the energy of an EM wave and its wavelength and frequency. - Calculate the frequency and the wavelength of an electromagnetic wave. - Explain why the range of wavelengths detected by the human eye is limited.

#### Refraction

(1)
Design for the new AQA 9-1 GCSE, this lesson covers where we find refraction and how water and light refract. At the end of the lesson students should be able to, - identify what happens to the frequency, wavelength, direction and velocity of a wave during refraction - draw a ray diagram showing the refraction of light through a glass block - describe how the properties of light change as it is passes through a glass block. Rate and please leave a review!

#### Sound Waves

(2)
Designed for the AQA Physics GCSE 9-1 course, this lesson builds upon students knowledge of longitudinal waves and focuses on sound waves. Students will: Understand how the vibration of sound waves allow us to hear. Show how frequency and amplitude affect a sound wave. Describe how sound waves travel through mediums such as solids, liquids and gases. Understand the limits of human hearing. Calculate the depth of water using echo sounding/location. I recommend using an oscilloscope to demonstrate the differences pitch and loudness have on the appearance of a sound wave. The lesson includes and inspiration and amazing video of a young boy who has learnt to use echo-location to help him &quot;see&quot;. Please leave a review :)

#### The Skeleton

(5)
Lesson aimed at year 7 and 8 students on the skeleton. Images and content taken from Kerboodle and placed in a easier to deliver PowerPoint. Includes a name the bone exercise which I used as a starter activity.

#### SI Units, Measuring Quantites and Standard Form - An Introduction to KS4 Physics

(1)
This resource is used at the start of the year with my KS4 Physics classes. It covers topics such as SI units and why they are important, quantities and symbols. Students also show what instruments should be used to measure each quantity and how they can improve the accuracy of a reading. The second part of this resources goes into standard form and why this is very important. Students are given worked examples of how to convert into standard form and a worksheet that allows that to convert from decimals to fractions to standard form. Can be used as one whole lesson or split over two.

#### Solar and Geothermal Energy

Design for the OCR H156 A/S level. This lesson covers the wave equation and the relationship between intensity, amplitude and distance from the source. This resource includes a presentation and a worksheet that accompanies it. Learning Objectives Understand and apply the formula v=fλ. Understand the intensity of a progressive wave I=P/A and that intensity α amplitude2

#### Reflection

(1)
Designed for the new AQA GCSE 9-1 specification. This lesson builds upon properties of waves and looks at reflection. Students will be taught how to draw ray diagrams and show the reflection of light against a mirror, stating the relationship between the angle of incidence and the angle of reflection. Students will then apply this knowledge by looking at periscopes and drawing the path light rays take. Support sheets are provided to help with drawing ray diagrams through a periscope.

#### GPE & KE (Felix Baumgartner)

(0)
A lesson that builds upon students knowledge of gravitational potential energy and kinetic energy by using the example of Felix Baumgartner's record breaking free-fall. There is a PowerPoint and Worksheet which can be marked in class and scores taken in. I recommend students have a prior knowledge of what GPE and KE are. YouTube links are with in the PowerPoint and no images are my own.

#### Centre of Mass

(2)
This resource is a whole lesson on centre of mass designed for the AQA GCSE Physics 9-1 specification. The success criteria for this lesson are, All - Recall what is meant by the centre of mass and find the centre of mass for a symmetrical object. Most - Find the centre of mass for an irregular object. Some - Balance twelve nails on one single nail using their centre of mass. There are extension task related to each task. The final activity will require 13 nails and a piece of wood as demonstrated in the images on the presentation. All images that are not my own are referenced in the notes on the presentation.

PowerPoint on how organisms are adapted to their environment and how they may compete with one another. I am lucky enough to have access to a farm, so I took the students down to the farm where they then completed the worksheet. I left one row free for them to choose an animal of their choice. Images could be shown of the animals instead of going to a farm. Aimed at year 7 and 8 students but equally could be used across a wide range of ages dependent on ability. I used the worksheet to differentiate, with higher ability student being able to write down why the adaptation was an advantage for the organism.

#### Solids, Liquids and Gases

(0)
This at aimed at KS3 but could be used for a low ability KS4 lesson. It is designed for the AQA KS3 syllabus and builds the students towards GCSE. Students will be expect to achive the following: Know – Describe the properties of a substance in its three states. Make relevant observations in order to decide is a substance is in its solid, liquid or gas state. Apply – Use models to investigate the relationship between the properties of a material and the arrangement of its particles. Compare the properties of a substance in its three states. Extend – Argue for how to classify substances which behave unusually as solids, liquids, or gases. Design and explain a new representation for the particle model.
