A simple but beautifully well illustrated set of Keynote slides to help teachers introduce students to common scientific measuring instruments and their precision. The first two slides link precision to the scale division of the instrument and the use of different prefixes for the same measurement and uncertainty. Includes high quality diagrams to help link the measurement concept to use of the real instrument. A slide at the end shows how to indicate precision in tabulated results. Instruments covered in this presentation deck: Ruler Vernier caliper (standard precision ± 0.1 mm) Micrometer Voltmeter (digital and analogue versions [10 V shunt ± 0.2 V] Handheld stopwatch Thermometer Weighing scale This presentation is available to you for free, but it is copyrighted - no alterations are to be made and it is not to be distributed further. This is made with Keynote which is Apple’s presentation software. It can be exported to PowerPoint but I don’t guarantee the output will look and operate in the same way. Keynote is an app available on macOS, iOS and iPadOS for free with most new or new-ish Apple devices.

A Keynote presentation to help teach your students how to present science experiment results in tables and graphs. The presentation includes a good table and graph with animated bullet points to draw attention to the good features. A premium version of this activity is available with a worksheet and with an annotated erroneous table/graph: >> The premium presentation includes a table and graph with errors that the students try to identify - they can annotate the accompanying worksheet. Each error is identified with animated annotations in the presentation. Keynote is presentation software for macOS, iPadOS and iOS

A Keynote presentation with worksheet to help teach your students how to present science experiment results in tables and graphs. The presentation includes a table and graph with errors that the students try to identify - they can annotate the accompanying worksheet. Each error is identified with animated annotations in the presentation. A good table / graph is then shown to illustrate the good features. The worksheet includes the good table and graph for optional sharing with students after the activity. A free version of this activity is available without the worksheet and without the annotated erroneous table/graph. Keynote is presentation software for macOS, iPadOS and iOS

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.
