8) Strong points: The 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 have to remember “Stoichiometry” and use the quantity called a "mole". Students can delve into the heart of chemistry and can learn ways of representing molecules and how molecules react.

Students can learn that all materials are made of chemicals, and chemical reactions involve interaction between chemicals such that all reactants are changed into new materials.  https://www.brightstorm. com/science/chemistry/ch emical-reaction-rates/

1) Pedagogical goal a. Remedial practice. b. Further consolidation and revision practice in class. c. Support as teaching instrument/s, especially while expounding new contents d. Practice of consolidation and further development 2) School Level: 10-12 3) Level of difficulty: from the average level to high level 4) Language: English 5) Interactivity: No 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.

Students can learn that the properties of the new materials are different from those of the reactants, and this is distinct from other changes such as evaporation, melting, boiling, freezing and mixing where changes involve no new substances.

Students learn that chemical reactions involve breaking chemical bonds between reactant molecules and forming new bonds between atoms in product particles. http://www.chimicaonline.it/download/ classificazione-reazionichimiche.htm

9) Overall review 10) Example of use Every part of these topics are treated very well in the theoretical part, and can be used both to consolidate the already done lessons or to explain new contents.

The exercises are grouped in three different categories (low level, medium level, high level) and so can be used for different purposes.

Weak points: -Strong points: there is the translation in over ten different languages. Simulations are well done and games are very interesting and instructive.

Overall review

10) Example of use It can be used as a revision for the part of chemical equations and conservation of mass.

Students can learn that the number of atoms before and after the chemical change is the same but the number of molecules will change. It explain how balance a chemical equation, recognize that the number of atoms of each element is conserved in a chemical reaction, describe the difference between coefficients and subscripts in a chemical equation, translate from symbolic to molecular representations of matter.

Simulations are very interesting: you can use the simulation to see how many products you can make with different amounts of reactants. Students can play a game to test their understanding of reactants, products and leftovers.
