School Level: 10-12 class Level of difficulty: medium Language: English Interactivity: Yes Problems: None Weak points: ‌ 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 The chemical bonds 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 learn that chemical bonds are the glue that hold molecules together. They will learn about the different kinds of bonds, ways chemists draw bonds and molecules, and how the type of chemical bonding affects the bulk properties of a material. Students can understand electronegativity, Lewis dot structures, VSEPR, bond hybridization, and ionic, covalent, and metallic bonds https://www.brightstorm. com/science/chemistry/ch emical-bonds/
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) 3) 4) 5) 6) 7) 8)
School Level: 10-12 Level of difficulty: medium Language: English Interactivity: No Problems: No Weak points: There are no exercises. 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. At the end of this chapter, there are tips that students can use as revision. The online video lessons in “Chemical Bonds� unit discuss the bonds that can form between compounds and the molecular, chemical and physical properties of these bonds. http://www.chimicaonline.it/download/ legami_chimici.htm

School Level: 10 -12 class Level of difficulty: medium Language: Italian Interactivity: No Problems: None Weak points: there are no exercises for this topic but only some exercises about VSEPR theory 8) Strong points: To enter just click on the name of the chemical bond. Theoretical contents are explained well and clearly, even if the topic is very difficult. 9) Overall review 10) Example of use The chemical bond is 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 http://phet.colorado.edu/e n/simulation/legacy/molec ule-polarity
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. Simulation e. Didactic material/s useful for experiments or practical activities 2) School Level: 10 -12 class 3) Level of difficulty: medium
4) Language: English 5) Interactivity: Yes 6) Problems: you have to register before using “teacher tips�. 7) Weak points: -8) 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 polar bond, polarity and electronegativity. Simulations are very interesting: you can use the simulation to explore how light interacts with molecules in our atmosphere. It explain how a molecule is polar. Students can change the electronegativity of atoms in a molecule to see how it affects polarity. Students can see how the molecule behaves in an electric field, and change the bond angle to see how shape affects polarity.
