Problem: The problem is, trying to learn about the elements and some information about them in chemistry. The app should be able to help the student understand something about chemistry. For example, the periodic table or ionic bonding/covalent bonding.

Some solutions: Some ways you could solve this problem is, find a video explaining how it works, finding an app that helps you understand it so you can use that app in class, search it on google, or ask a friend or teacher. If you find an app, there could be apps that solves the problem and solves even more unown problems you might have in the future. If you find a video, it will probably help you understand chemstry more because the video could go through the problem more slowly and give you some practice solving equations. If you ask a friend or teacher, you can learn how to solve it and you can ask questions about it, something you can’t do in a video. If you search it on google, it can show you different websites that has many explanations.

The app I found is called Chemistry. The description is: Solve reactions easily and use periodic table for education at school and university.

This app has a periodic table, information about the elements like solubility. The periodic table shows all elements and when you click on a element, it opens Wikipedia without opening safari and shows information about the element.

This app also has a chemical solver. You type in a chemical, for example CO2 and H2O, and it gives you the answer which is H2CO3. Another example is C and O2, which is CO2. If you add two element in an ionic bond or a covalent bond, you also get a bunch of other formulas.

 

This app also has a molar mass calculator and a solubility table. The solubility table tells you how soluble the mixed element is (which means how much it can disolve), the table has a color and the number tells you how soluble it is. The molar mass calculator calculates the percentage mass of an element. For example Lithium has a molar mass of 6.94 and in a precent it is 100.014409221902%.

 

This app is definitely a good app to use. It has a lot of imformation about the elements and has other useful functions. The app uses Wikipedia for the information for elements. It also probably uses other online stuff to help this app be useful. This app can could be used to help app users learn about the elements and can find answers to a question on their sheet. A problem is, this app seems like it’s mainly used by people who already understand how elements bond. Another problem is, some of the information is wrong. For example, Manganese’s amount of electrons in each shell goes like this:2,8,13,2 in the app. It should go like: 2,8,8,7.The app also is very hard to figure out for people who are new to chemistry because there is no explaination of how to use the app, so you have to figure things out on your own and play around with it. Also, the element table page goes blank sometimes so you have to reload the app to see the table again. This app seems very useful to older kids who knows how to combine the symbols for the elements. For example C and O equals Hexacarbon Tetraoxide. This app is definitely not a good choice for the kids who are doing chemistry in grade 9 because it doesn’t show how ionic bond or covalent bonds work.

 

Some changes I would make is, I would spend more time trying to find an app that will benefit grade 9 students and help them learn more about the useful things. I also should have spent more time testing out the app so I can give more information about the app. Some problem I encountered is, There wasn’t many apps on the app store that was free and looked like you could learn something from it. If I could have, I would have spent money on apps that looked good and I would test it out to see if students can learn anything from it.
