Note: This would be a great followup practical after completing your Pythagoras Cup. Practical 5 in the History in STEM practical series. In this practical we are looking at the humble beginnings of the alarm clock. This version is based on a design believed to be used by Plato, to make sure he got up on time. It teaches a number of concepts, such as siphons, as well as displacement and air pressure. It takes the principle of the cup and applies it in a new way. When the water siphons into the vessel, it displaces the air out, forcing it through a whistle, causing it to sound. You can tweak the practical to have the time it takes for the alarm to go off, to suit whatever purpose you like. This is probably more than a single lesson practical, but might be a good collaborative project. Bring the Arts department in to get some cool decorations for the clock. Get the history team to talk about Plato and the philosophers of ancient Greece and turn this practical into a real cross curriculum event. More about the History in STEM practical Series This series is designed to bring quality cross-curricula material to STEM subjects, that help students to explore and discover phenomena normally taught, while getting a glimpse into the history of its development. In addition, a number of the practicals give the students the opportunity to play “Mythbusters”, looking at a number of different methods and having to reason why one or the other was the more likely or useful method. From Ancient Greece to Vikings, China to the Golden age of the Muslim empire and beyond to India, the series takes a look at some of the most important STEM achievements throughout history. There is a plan for 40 of these such practicals in this series, so, if you liked this one, consider looking at some of the others, or check out some of the bundles available.

Practical 6 in the History in STEM practical series. In this practical, you will be using similar triangles to measure how far off distant objects are. This technique is believed to have been used in Ancient Greece and other locations for a number of reasons and is a very simple to conduct, group work activity where each member has defined roles, ensuring that participation is high. It can be used and adapted to teach a number of aspects of similar triangles, but as it is set up, would be a great introduction to the topic.

Practical 7 in the History in STEM practical series. In this practical, you will be looking at the illusive history of invisible ink and the chemical reactions behind them. Have a look at the different methods used, beginning in Ancient Greece and continuing through history all the way through to modern times. Test their effectiveness in application, invisibility and ease of development, and decide for yourself, which of the methods you would choose. Finally, take your knowledge and apply it to working out the teachers secret message. Which method did they use? Use observations and clues to make your deductions and then test your hypothesis.

Practical 4 in the History in STEM practical series. In this practical we are looking at the Viking Sunstone, the theoretical genius navigation method, making much of the Viking exploration possible. Working with Icelandic Spar (Calcite Crystal) which, through the process of birefrigence, causes light passing through it to be refracted at two separate angles. Using this, with some small effort, research has shown that the stone could be used to locate the sun, even on an overcast day, within a few degrees, allowing for the journey to continue.

Practical 3 in the History in STEM practical series. In this practical we are looking at the famous cup attributed to Pythagoras. Working with a siphon, it “punished” anyone who became too greedy. Students will be able to produce their own “Greedy cups” as they are otherwise known, using some simple materials, most of which you may already have in your staff kitchen cupboard.

Practical 1 in the History in STEM practical series, looking at how students can do an experiment completed over 2000 years ago to get their own reasonably accurate value for the circumference of the Earth. Requires minimal equipment and very little time to get the data, however, does need you to be able to work with another school in a** different city** to get all the data points required to complete the calculation. Good for schools with a “sister school” in another state or country.
