Practical 28 in the History in STEM practical series. In this practical the students will start by reading about the history of firefighting throughout the ages, including a focus of how a WWII Aircraft Carrier was saved through the use of carbon dioxide during the Battle of Midway. After, the students will use various methods (acid-base reactions and decomposition with catalyst) to produce various gases which will then be flame tested to confirm the identity. This practical is a great way to combine history and chemistry together in one lesson and the experiments really allow the students to explore various aspects related to reactions. **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 about 35-40 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 27 in the History in STEM practical series. In this practical the students will be able to test the effect of various heat treatments on bobby pins to determine what properties each treatment gives, and what would they appropriately be used for. The practical does not require much equipment, but gives real quantitative data for comparision. It also gives a chance for the students to delve into the history of metals. The introduction discusses the Stone, Bronze and Iron ages, as well as some examples of how heat treatment was used throughout history. When working in a group, if the equipment was already laid out, the data for this practical could be collected in 45 minutes.

Practical 18 in the History in STEM practical series. This is part 2 of a 2 part series of practicals covering the history and development of the camera. This practical starts looking at producing and developing photo paper using a pinhole camera and household chemicals, and is followed by a method to produce photosensitive paper using silver nitrate and sodium chloride. As always, there is an intro looking at the history of the camera and photo development, including its use across the world and a quick look at its discovery. The practical is probably best suited for 90 minutes, to give students time to explore.

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.
