Practical 15 in the History in STEM practical series. This practical set focuses on three aspects of ocean acidification. After an introduction looking into the history of ocean acidification through time, it moves into practical 1 gives a quick demonstration of the effects of increasing atmospheric CO2 using an acid base indicator and a simple reaction. Practical 2 is a card game that focuses on the effects dissolved CO2 has the ability of organisms to repair their shells. Practical 3 takes a longer term look to give a model to show the effect on shells over a period of weeks. The combination of the 3 gives a great depth to the topic, while also giving the students a number of hands on activities to keep them engaged. The practical file is editable to suit your needs. Instructions for Teachers - Card Game The pages are set so that, when printed double sided, they have a back and front, enabling for easy sorting. Before you print the whole deck, test your settings by printing the first two pages of cards, to check alignment. If it doesn’t match, then its likely to do with how the printer flips the page (either long end or short end), so make sure it is on the flipped on the long end. If you don’t want backs, then print every second page. There are two sizes of cards, mini and large, so have a look at both before you print. Contents: 8x Hydrogen Cards, 8x Hydrogen Carbonate Cards, 19x Calcium Cards, 19x Carbonate Cards, 1x Information Card This card game works in 4 rounds. This works best in groups of 4, but can work with less or if necessary, up to 5 players per deck. Each player is role playing as a crab. Round one: The game starts by placing all of the Calcium and Carbonate Ion Cards face down on the table, as well as two hydrogen and two hydrogen carbonate cards. Each person picks up 4 positive ion cards and 4 negative ion cards. The goal is to match Calcium with Carbonate. If you have 4 pairs, your shell grows. 3 pairs means enough minerals have been gathered to repair their shell. 2 pairs means damage cannot be repaired, but doesn’t worsen and 1 pair means the shell gets further damage and cannot be repaired. Record the scores on a tally card. Round two-four: At the end of the first round and each round after, all the cards are returned to the table, face down and an additional two hydrogen and two hydrogen carbonate cards are added, symbolising the acidification of the ocean through the dissolving of more CO2. Same rules for shell repair apply. Person with the most points at the end wins (pairs). Enjoy. More abo Copyright © 2020 The Efficient Science Teacher All rights reserved by author.

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. 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 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.

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 11 in the History in STEM practical series. In practical 11 continue to look a little more into the paper industry, as well as its impact on the world in terms of deforestation. In the practical section there are instructions for a classic paper making experiment, with a twist. There are not just instructions for recycled paper, but for cotton paper, leaf paper and grass paper. The students then need to look at the strengths and weaknesses of these paper, and assess whether they could become suitable alternatives to wood pulp, thus reducing the impact on the forests by the wood and pulp industry. So, rather than just looking at the theoretical, this practical encourages students to actively seek answers to today’s burning questions.
