A Keynote¹ presentation for introducing students to handling experimental uncertainties in science measurements. Topics covered are: types of error (systematic and random), absolute and percentage uncertainty, and rules for determining uncertainty in calculated values (five calculation rules in total). There is also a sample of exam questions - three for each rule (except rule 1 which has just one exam question). Also included in addition to the above: An explanation of uncertainty in handheld stopwatches. Examples - notably an example question with full worked solution for each calculation rule. There is a lite version of this slideshow available for free so you can get a feel for the resource prior to purchasing this slideshow if you would like to do so. Note that the Lite version does not contain all of the teaching content of this presentation; the rules for multiplication by coefficients and calculation with complex functions (trig and logs) are only available in this version. ¹ Keynote works on iPhones, iPads, Macs and in many web browsers.

A spreadsheet that can be used to analyse the data obtained in the experiment to investigate light intensity and distance like in this video. The spreadsheet automatically calculates the power of the light source and percentage difference with the manufacturer’s rating from inputted distance and light intensity data. The data plots are added to a carefully formatted graph. A line of best fit is automatically plotted. The gradient of the line is automatically calculated from the data plots and the value of the source power is calculated by using the gradient. This spreadsheet is perfect for rapidly analysing experimental data. A second table calculates proportionality constants so that the user can very quickly check if their data obeys an inverse square law. This is a Numbers spreadsheet. It is possible to convert Numbers spreadsheets to Excel files but I cannot guarantee an easy to use output since the tables may be converted to separate worksheets in the Excel file.

A worksheet to enable students to analyse experimental data from the experiment to investigate light intensity and distance. I’ve made a video of the experiment here youtu.be/TpSghS5Hzsw. The data collected in the video can be used to complete a table, plot a graph and answer a series of analysis questions in order to determine the power of the light source. There are links from the PDF directly to the relevant part of the data collection in the video for anyone using the worksheet electronically. There are solutions at the end. Perfect for A-level physics students on any specification. This worksheet is ideal for home learning since it has an accompanying video explanation of the experiment, the analysis of results and solutions to all questions are included in the document.

This spreadsheet will solve your problems involving the equations of uniform acceleration. If you’re a physics teacher you’ll need to solve a lot of these problems at certain times of the year, you may even need to invent your own questions. This may speed up your workflows. Simply input your data (s u v a and t) typing a question mark by the unknown quantity. Then select the equation you need to use from a drop down menu and the answer is calculated. Calculations are performed on a background table, so at any time you can investigate what’s happening on that tab. Questions that lead to two values of t (due to the square root in some solutions) are solved and both values of t are shown.

A spreadsheet that can be used to analyse the data obtained in the experiment to determine the decay constant of an isotope like in this video. The spreadsheet automatically calculates the decay constant and initial activity from inputted time and activity readings using a natural log analysis. The data plots are added to a carefully formatted graph. A line of best fit is automatically plotted. The gradient and y-intercept of the line are automatically calculated from the data plots and the value of the decay constant is calculated by using the gradient. This spreadsheet is perfect for rapidly analysing experimental data. The initial activity is calculated by using the y-intercept, this is a useful indicator of the accuracy of the final value. This is a Numbers spreadsheet. It is possible to convert Numbers spreadsheets to Excel files but I cannot guarantee an easy to use output since the tables may be converted to separate worksheets in the Excel file. Suitable for most physics specifications that cover nuclear physics.

A reference table to help students memorise measurements that occur in a wide range of physics practical work and the associated measuring instruments. Most exam series include questions on designing an experiment, a key part of which is to state the measurements to take and the instruments to use.

Activity for practicing calculation of y-intercepts for graphs with a false origin. This worksheet includes five graphs with lines of best fit already plotted. A student needs to draw the gradient triangle, determine the gradient and then use y = mx + c to determine the value of the intercept. Pages with solutions for all graphs are included in the document. The graphs cover a range of topic areas in physics (free-fall, Hooke’s Law, wave intensity, mass-spring oscillation and capacitor discharge). But since a student only needs to determine values for the gradient and intercept students do not need to be familiar with the topic in order to tackle the tasks. Suitable for AQA and OCR Physics A AS-Level and A-Level specifications. (7407, 7408, H156, H556) This worksheet is great for home learning since it has solutions to all questions included in the document and it is part of a series that gradually builds up a range of graphing techniques.

A Keynote presentation to aid teaching students how to use Vernier Calipers and Micrometers.

Copy of the spreadsheet I used to analyse the data obtained in the experiment to determine the capacitance of a capacitor in this video. The spreadsheet automatically calculates capacitance from inputted time and potential difference readings using a natural log analysis. The data plots are added to a carefully formatted graph. A line of best fit is automatically plotted. The gradient and y-intercept of the line are automatically calculated from the data plots and the value of the capacitance is calculated from the gradient. This spreadsheet is perfect for rapidly analysing experimental data. A second method of analysis is also possible using a second graph - a direct plot of p.d. versus time (exponential data). Instructions are included to guide the user in determining the value of the time constant and that is then used to calculate a value of C that can be compared with the first method. This is a Numbers spreadsheet. It is possible to convert Numbers spreadsheets to Excel files but I cannot guarantee an easy to use output since the tables may be converted to separate worksheets in the Excel file. Suitable for most physics specifications.

A detailed presentation to aid explanation of the role of radiation intensity in the photoelectric effect for various photon frequencies relative to the threshold frequency of the metal. Students often misunderstand the inability of increased intensity to trigger the photoelectric effect and therefore believe it has no role. This presentation is a visual aid to help the teacher show that it has a role in controlling the number of photons arriving per unit time. This presentation compares low and high intensity sources of red and green light with low and high intensity blue light (where green and blue light have frequencies above the threshold frequency). The effect of intensity on the number of photons arriving at the metal is made clear and intensity is clearly distinguished from photon energy. This is a Keynote presentation (macOS, iPadOS and iOS). Useful for all A-Level physics specifications. The photoelectric effect is an important experiment in physics that proves that light behaves like a particle, it was a founding experiment for quantum theory. Einstein won his Nobel prize for his work on explaining the photoelectric effect.
