Practical 16 in the History in STEM practical series. This practical set focuses, first and foremost on replicating Gallileo’s famous free-fall experiment. Students use modern technology to record with slow motion video and calculate an object in free-fall’s velocity, momentum and acceleration. There is also a proof of concept to show that surface area, not mass, is a major factor in determining acceleration. Finally, using YouTube, they look at momentum in moving vehicles, using technology to analyse video frame by frame to get an estimate of a cars velocity, momentum and accelaration. As always, it includes an introduction covering the history of the theory across multiple continents and over a period of over 2000 years. 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.

Topics covered in revision: Lock 1 - Cell Transport Lock 2 - Organelles Lock 3 - Meiosis Lock 4 - Protein Synthesis Lock 5 - Restriction Enzymes Lock 6 - Trophic levels Lock 7 - Gel Electrophoresis There are a number of ways you can use this resource. The most straight forward way would be to prepare each of the locks, and run it as a station with a timed period for the students to solve the puzzles, before rotating. The students, who think they have the code, could come to you for conformation, with a clarification of all the puzzles done at the end (ideally by the students, for further revision, but perhaps by you for one or two of the more difficult ones). The space for the location has been left blank for you to fill. I would suggest you put your school name, but anywhere is fine. Likewise, the space for the time to complete the task as been left blank. Fill it in by writing the number in before you begin. If you have more time and are feeling adventurous, you could actually go to the trouble of getting some cheap combination locks and boxes, setting them up at each station for the students to try. Make sure the locks that you get are programmable, to make them compatible with each riddle. Inside the box could be anything. I have, in the past, put extra clues in, which lead to a final test by having the students log in to the “Biology Bandits” account on a Raspberry Pi, with each piece of paper being part of the password and the lock numbers being the order they are entered into the pi. The desktop background gave the final confirmation of completion. As I said, the possibilities are endless. Most of the given puzzles require you to do no more than print out the instruction sheet for each group. If you decide to go with an actual lock, regardless of your method, you will need to set up the boxes and locks up well in advance. Any opaque box will do and you can adjust the puzzle as you see fit. For one round, in a pinch I simply took a sturdy envelope, poked a hole in the opening and locked the combo lock on it. As for the prize, that is also up to you. It could be a certificate or another goody of your choice. I managed to find some David Attenborough books for a dollar or two each one year, and they went down a treat. Make sure you have runner up prizes for those that don’t get the main prize. Point is, take these and have fun with them.

Practical 14 in the History in STEM practical series. With the upcoming equinox, this is the perfect moment to try out this practical. The more indepth version of Measuring the World - Circumference of Circles, this extended practical takes place over 3 months, recording the angle of the shadow at solar noon once a week to determine a host of information, such as the latitude of the city you live in, the tilt of the earth’s axis, confirm dates of solstices and equinoxes as well as calculate the circumference of the Earth. Each weekly measurement takes no more than 5 minutes, and can be done in small groups on rotation. After the 3 months, graph your data and have a look at the trends to deduce the range of information described above. The end result is a project that covers angles, graphs, and an optional triganometry component for advanced level students. There is even a task that a photography class could tackle to get even more accurate results and add an additional layer of cross-curriculum goodness. Don’t forget each comes with an introduction covering the history of the topic in question, in this instance, calendars. The file is editable to suit your needs.

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 13 in the History in STEM practical series. What better way to celebrate the upcoming Pi Day then with this series of activities to calculate Pi. Try 4 different methods of calculating this amazing number, ranging from basic all the way to modern methods of computation: Method 1: The classic. Compare ratio of circumference to diameter. Method 2: Use Archimedes ancient method using polygons. Method 3: Try something a little different with Buffon’s Needles Method 4: Go new school with some python and the infinite series Note: You do not need to know how to code for this. If you install the free program Anaconda, there are instructions in the sheet on how to open the file in the zip folder to run the simulation. Each of the methods takes a different approach from a different era in the race to get the most accurate Pi value. Method 1-3 require very little setup. Comes with the editable activity sheet, a history of the calculation of Pi introduction and the Jupyter notebook file for the coded calculation.

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.

Practical 20 in the History in STEM practical series. This practical experiment looks at a material, Pykrete, developed during WWII that was ultimately deemed a failure, but is perfect for testing forces and strength of different materials. Comparing up to 4 versions of ice with different added components to augment the properties, students will test its strength and ability to hold masses of increasing size, as well as time how the added substances effect melting time. A great way to look at a number of physics themes for any class already looking at WWII in their history lesson. Note: You need a freezer in order to complete this practical, all other materials should be able to be obtained relatively easily.
