But this is not the only science that developers are working on popularizing today. And, of course, their attention did not pass by chemistry - the most interesting science of the structure of substances, which usually causes children to be terrified of incomprehensible elements and formulas. But, as always, it seems to be a matter of approach. Perhaps, if you diversify the study of the periodic table using various games and introduce children to the concept of chemical valence using a colorful and understandable application, then the subject itself will not seem boring or inaccessible to them. So we bring to your attention a selection of applications and games for learning chemistry.
An application for exploring the chemical elements, about which the English writer and actor Stephen Fry once commented as follows: “For the sake of this application, you should buy an iPad!”. The Elements is a kind of database of the main chemical elements presented in the form of high-quality 3D models. The app is based on The Elements by Theodore Gray, author of the Gray Matter column in Popular Science Magazine, but The Elements features go far beyond print.
For each element, an example has been selected, which is presented in the form of a rotating 3D model (for example, a tin soldier for tin, a gold ingot for gold, etc.), which can be independently launched, turned over, enlarged - in general, explored from all sides . Next to each element is a column of data and facts detailing its features. Developers characterize their product as follows:
The Elements is not a help application; is a rich and captivating love story of the periodic table, retold in words and pictures, allowing you to experience the beauty and majesty of the building blocks of our universe like never before.
Recognized many times as one of the the best programs to learn chemistry, The Elements is only $4.99. The app can be downloaded from iTunes. Unfortunately, the video review is only available in English, but even the visuals are enough to understand how good this program is.
In that free application you will find three-dimensional models of various substances. Molecules has several visualization modes that allow users to rotate models, scale the molecule, zoom in/out, and more. The application itself has a very decent database of molecular models, but at the same time, the user has the opportunity to download examples from specialized sites of international repositories of biological molecules and their three-dimensional models. To do this, enter the name of the substance in the search bar (Water, Gold, Insulin, etc.). Of course, comprehensive information is presented here about each molecule and molecular compound: the full name of the molecular structure (and do you remember that substances are most often called abbreviated, and the full name is usually known only to specialists?), the number and types of amino acids in the case of proteins, nucleotide sequences for DNA and RNA, the names of compound researchers, and more. The app is available on iTunes.
Created by a Michigan chemistry professor, this app helps users understand how molecules connect. The gameplay consists of five levels, each requiring the player to compose 2D Lewis point structures. The one who completed the task will be rewarded with the transformation of the 2D structure into a 3D model. In addition, at the end of each level, the application will give you a philosophical rhetorical question about the structure of the Universe and its substances, so even if you fail to comprehend valence, the philosophy of chemistry will become a little closer to you. You can download Chemical Valence from the App Store for $0.99.
This is a kind of virtual chemical laboratory in your mobile device. Here you can conduct experiments with various substances and observe the most unexpected reactions. As you understand, in the virtual space you can even experiment with explosives and radioactive substances. The results of the experiments are simulated in real time, while the program takes into account a bunch of parameters: air composition, ambient temperature, mass and volume of mixed substances, etc. To make the task easier for a novice chemist, the base of the main reactions for each substance from the periodic table is available in the application. However, you can "chemize" and discover your own reactions. The Chemist Lab is available on iTunes for $4.99. But there is also a free trial version.
Think another chemistry lab? Didn't guess! Chem Lab is a fun quiz that will test your knowledge of basic chemical formulas. The user is prompted to perform 5 tasks in turn (drag the necessary elements into the test tube to obtain gas or combine suitable substances, etc.). At the end of the experiments, the required results for each task are shown and compared with your achievements. Be careful - if the reaction is unsuccessful, something may explode or catch fire. Of course, working in the application is safe, but the explosion at least suggests that in reality it is not worth repeating such an experience. The app is available on the App Store and costs only $0.99.
Talking Ben the Dog is a game for the little ones. Talking dog Ben is a retired chemistry professor who is tired of life. All he does is eat, drink and read newspapers. You can try to stir it up, or you can simply press the "Chemistry" button and send the old professor to the laboratory to conduct simple chemical experiments with him (mix two liquids and observe the reaction). Nothing particularly educational, but at least the child learns that mixing two substances can lead to an unexpected reaction. It seems like a good start for telling a child about chemistry as a science. The app is available for free on iTunes and Google Play.
Another tool for studying chemistry, which allows you to get acquainted with the activity of elements, study redox reactions, solve problems in chemistry, obtain the final reaction products and equalize coefficients. The application contains a description of the reactions of more than one and a half thousand chemical compounds. The application interface is extremely simple, however, as well as working in it: for the reaction, just select from the table necessary elements and connect them. The application can be downloaded from Google Play for free.
Game app for learning chemistry. Now you do not need to force your child to cram chemical elements, just install Elements Quiz for him, where the periodic table is studied in a simple game form. The basic rules of the game are to look for the chemical elements offered by the program in the table. What could be easier? But the child in the process of such a search gradually remembers the name of the element, its symbol and place in the table - the basics that are necessary for further successful study of the subject. For more advanced users, the application has built-in quizzes that are not so easy to handle. In addition, the application is linked to Wikipedia, so you can always get Additional information about this or that element in the free encyclopedia.
This is an application that allows you to easily draw the formulas of organic compounds. But, as users note, it is impossible to describe and depict full-fledged reactions in the program, so MolPrime + can still be used only as a formula editor. By the way, it is easy to share your achievements in the application with friends via twitter and email so that you can compete in skill. MolPrime+ is easy to download from
Chemistry Olympiad for 11th grade students consists of 6 tasks. In the final assessment of 6 tasks, 5 solutions are counted, for which the participant scored the highest points, that is, one of the tasks with the lowest score is not taken into account. For each correctly completed task, you can get from 1 to 10 points. You have 180 minutes to complete the task. No special equipment is required for the job. It is allowed to use a non-programmable calculator, a periodic table of chemical elements, a table of the solubility of acids, salts and bases in water and a metal activity series / electrochemical voltage series.
The game was created for all lovers of chemistry. The goal of the game is to make up a term in chemistry from the letters, the definition on the slide is a hint.
The program in which the development was created: PowerPoint 2010. Macros must be enabled when starting the presentation.
The target audience: for grade 11
The program is designed to solve simple calculation problems in chemistry based on ONE reaction equation. She herself composes, balances the equation and performs calculations after choosing the starting materials. The solution is presented in text form with short explanations. The main difficulty, in my opinion, is the introduction of the conditions of the problem (the program itself gives some hints, but you still have to practice).
Schoolchildren (even those who are practically not familiar with theoretical chemistry) will be able to solve the problem if, of course, they correctly transfer these conditions from the textbook to the program. And the program will help specialists to get a numerical answer in a minute, without resorting to reference data and a calculator.
The program draws up reaction equations based on the general theoretical principles of chemistry, so non-standard processes can be written incorrectly (however, they are unlikely to be used in school). Nevertheless, I will be grateful for the comments and suggestions that should be made.
I tried to take into account the comments of experts on tests based on presentations (and added something of my own). The test consists of 10 tasks (not a problem to change), and the set of tasks is not repeated from test to test. Each approach will test tasks of all types (single-sample closed, concept matching and open). Two levels of test difficulty (middle school students, Olympiad).
Conclusion complete information about the passed test on the screen and the file in the program folder. If available computer network the whole class can be tested, and the total resulting information is recorded on the teacher's computer.
I will gladly listen to constructive criticism.
Target audience: for grade 11
For most schoolchildren, the formula of a substance is an abstraction, not associated with any of his feelings or memories. This chemistry game created to make up for this omission. I hope the student will remember that NO2 is a brown gas, heavier than air, can react with H2 and NaOH and does not react with O2 and HCl; maybe even learn to apply density and relative density to his selection.
The second level of complexity is for those who know this, who can think and compare facts. What am I writing?! You try it yourself! I can assure you, it won't be easy at first. In short, the second level is good toy for teachers and olympiads. You can even try to hold a tournament among colleagues and win (only they are unlikely to want to participate)
Target audience: for grade 11
The subject is chemistry. Main purpose - calculation of the mass fraction of a substance in a solution(when dissolving, diluting, evaporating; also for the case of substances that react with water and crystalline hydrates) and determining the required mass ratio of the components to obtain a solution of the required concentration. Recalculation of all types of concentrations(mass fraction, molar, mole, mole fraction) from one to another. There is a small block with theoretical material on this topic.
All files after unpacking should be in the same folder.
Alleged audience - wide, incl. teachers.
Target audience: for teachers
