http://www.chemistry2011 1) Pedagogical goal .org/branchesofchemistry a. Further consolidation and revision practice in class. b. Support as teaching instrument/s, especially while expounding new contents c. Practice of consolidation and further development 2) School Level: 11 class 3) Level of difficulty: medium 4) Language: English 5) Interactivity: no 6) Problems: There are some videos that could be used as lab simulation, but they are no more available 7) Weak points: The links to the website where the topic is explained are hard to find: you have to search them in inorganic and physical chemistry. The secondary website does not explain in detail the topic but does only a fast overview of atomic orbitals and electronic structure (for inorganic chemistry); atomic structure must be fetched in physical chemistry.

8) Strong points: For each topic there are some references to go deeper in the topic. There is a summary at the end of each of the chapter. At the end of some chapter there are exercises.

9) Overall review 3 stars 10) Example of use When you find “Atomic structure” in Physical Chemistry, you can see that the theoretical parts are explained in simple words. Teacher can use them as a revision in class, either as a consolidation for further development.

Students can understand atomic orbitals: s and p orbitals in some detail, including their shapes and energies, d and f orbitals only mentioned in passing. Students will can use “The Aufbau Principle” for the filling of the orbitals https://www.khanacadem y.org/science/chemistry

Language: English Interactivity: yes Problems: none Weak points: ‌ Strong points: display of the meaning of Binomial distribution videos explain clearly the topic and can be used both for a revision of the topic, both for help to expand the knowledge.

9) Overall review 10) Example of use Students can learn that chemists describe the structure of atoms using models. This section will cover the Bohr model, photoelectric effect, absorption and emission spectra, quantum numbers, and electron configurations.

The atomic models are explained in simple words and can be understood very easily, can be used either for the revision of the topic or to explain new concepts.

Students can use these tutorials to understand how to write electron configurations and to see how the quantum numbers predict the orbitals available in different energy levels.

Support as teaching instrument/s, especially while expounding new contents d. Practice of consolidation and further development 2) School Level: 3) Level of difficulty: from the average level to high level 4) Language: English 5) Interactivity: partly 6) Problems: no 7) Weak points: There are no exercises.

8) Strong points: The videos are clear in all parts and explain in a good way ad with simple words the topics treated.

There is a transcription of the videos so if someone lacks in listening skill, still can follow the lesson. The topics can be easily found from the index in the left part.

9) Overall review 10) Example of use The videos can be used either for revision or to get a deeper insight in the topics.

The online video lessons in the Atom unit discuss the structure of atoms, the particles of which atoms are composed, and the interactions between these particles at the subatomic level.) http://www.chimicaonline.it/download/model lo-atomico-a-orbitali.htm

1) Pedagogical goal a. Remedial practice. b. Homework assignments. c. Further consolidation and revision practice in class. d. Support as teaching instrument/s, especially while expounding new contents e. Practice of consolidation and further development 2) School Level: 10 -12 class 3) Level of difficulty: high 4) Language: Italian 5) Interactivity: No 6) Problems: none 7) Weak points: only in Italian 8) Strong points: there are both exercise and theoretical contents that are explained well and plain even if the topic is very difficult.

9) Overall review 10) Example of use The exercise can be used either as a remedy or as homework or as revision in class.

The theoretical parts are explained in simple words and they can be used as a revision in class or as a consolidation for further development.

School Level: 10 -12 class Level of difficulty: medium Language: English Interactivity: Yes Problems: No Weak points: -Strong points: there is the translation in over ten different languages. Simulations are well done and games are very interesting and instructive.

9) Overall review 10) Example of use It can be used as a revision for the part of the models of the Hydrogen Atom.

The detailed for each element can be used to expand the contents for students that want to know more about them.

It explain how scientists figured out the structure of atoms without looking at them. Students can check how the prediction of the model matches the experimental results.
