Welcome to Science Lesson Resources for Teachers and Parents!

     Have you tried mixing soda with vinegar? This is an acid-base reaction. When you burn something, it's a redox reaction.  Let's see the list of all the reactions! It is very big List of organic reactions - Wikipedia

Phones and laptops can work while not plugged into a socket, because they have battery inside.  The best batteries as for now work on metal called lithium . When damaged, these batteries can set on fire or even explode.  Be careful - do not break or heat your phone. Remember - there is a battery inside it! Here is the video: https://www.youtube.com/watch?v=FWe2G_AChDM

 Each color has many shades. Some are very beautiful. These shades are very popular.  Choose - which once of them you like the most: https://www.eggradients.com/blog/pretty-colors Anodized titanium can have many different shades, depending on the voltage of the electricity used. This coating is cheap and stable. Which shade do you like the most?

 Here is a nice overview of the history of perfume components:  https://drive.google.com/drive/folders/1O4kFM6SLQvGO77uPqAFVYIRvSBasBMXI?usp=drive_link Amazing lectures about the history of perfumery - with chemical formulas, done by Luca Turin, an experiences scientist.  https://www.youtube.com/watch?v=dflw8uRG7Rc&list=PL_brJ8c_lV9LoBMXx1IXSHTISaYD3geSf&index=16    Our nose works like an IR spectrometer - we can sense molecular vibrations! There are many clever experiments with fruit flies that can used to prove this theory.    We can smell separately functional groups like SH, C=N, COOR, etc., and the whole molecular vibrations in the `fingerprint` region of the IR spectrum.

 Before the chemical elements were discovered, people believed that all materials are made of only 4 elements: Fire 🔥   🜂 Air 💨      🜁 Water 💦 🜄, and Earth 🪨 🜃 Let's play this game:  Little Alchemy Or do you like this version better?  Little Alchemy 2 Extra activity : Can you draw these alchemical symbols? Alchemical Symbols (Unicode block) - Wikipedia They were believed to be made out of the four elements: fire, air, water, and earth. Hint:  You may create a table/ chart, to mix each element with the others:

 1, Click on the link Chemical Structure Search (chemspider.com) 2. Draw the structures from the worksheet 3. Find out their names 4. Search their properties and how they are used Or use the old `LEGACY` version of the web site: Chemical Structure Search (chemspider.com)

 Here is a web site with a lot of fundamental chemistry topics covered in small clear articles: Chemistry Page|Chemistry Page 1. Click on the link 2. Choose one topic that you like 3. Read and take notes 4. Present your favorite topic

    How shall we start learning about atoms and elements? Let's draw the first three atoms one by one! Let me introduce to you hydrogen, helium , and lithium , Let's see short videos of how hydrogen bubbles fly up, because they are lighter than air, and how helium can change your voice. Then we can learn about protons, neutrons, and electrons.
