Chemistry
Although Mortaza shows interest in almost any branch of science, chemistry is by far his favorite.
Periodic Table 
Fall - 2020 (1st grade)
Mortaza has been fascinated by the Periodic Table and the properties of the groups of elements in it. He has also created his own extended periodic table with his additional imaginary elements.

Drawing Molecules 
Fall - 2020 (1st grade)
Mortaza has drawn these molecule structures, some of them real molecules, the rest his own creation which might not exist in the real world.  
Chemistry Crafts 
Fall - 2020 (1st grade)
Here are chemistry related hand-crafts that Mortaza has made.

Ions and Chemical Reactions 
Fall - 2020 (1st grade)
Mortaza has his own understanding of chemical reaction which seems to be a combination of reality and his imagination.
Mortaza's Journal 
Fall - 2020 (1st grade)
Mortaza's aunt sent him a notebook as a gift so that he could write his thoughts in it. He wrote (actually asked me to write) two entries in it. One about atoms that their number of neutrons are the same as their number of protons. The other one was about di-atomic elements. That is, the elements that their molecule is a combination of two same atoms. We learnt that there were seven of them: H2, N2, O2, F2, Cl2, Br2, and I2. 
The rest of the journal is filled with molecules (most of them Mortaza's creation). Over around 95 pages, Mortaza asked me to draw a wide variety of molecules. He was very specific about the shape and the atoms that formed them. This happened during the time period of October 3rd to December 1st 2020.

Chemistry Handbook 
January 5- 2021 (1st grade)
Here, I caught Mortaza pretending to read his handbook of chemical elements.
Experiment Station 
January 9 - 2021 (1st grade)
Mortaza can occasionally earn "stars" for his good behaviors at home. When he has three stars or more he can have a treat, which can be allowance to buy himself something when we are out shopping. For his latest treat, he chose to buy a chemical experimenting station designed for kids. There were tools and ingredients for nine experiments in the box. More about this experiment can be found here.

Drawing more complex molecules 
Early June - 2021 (1st grade)
Mortaza came up with these molecules (his own imaginations) and wanted to draw them with more details. He said the second one was both poisonous and explosive since the bound between phosphorous and carbon was unstable.

Extended Periodic Table  
June - 2021 (1st grade)
Mortaza asked me if we could make a periodic table in Excel with the feature that when we move the active cell over the table, the properties of the element would appear on the side of the table. We started by making the table itself.

Showing the properties of the elements on the side needed some advanced Excel beyond my skills. But I managed to learn them by watching a few videos and finally we managed to do it. Now the table shows not only some properties of the elements but also (for the first 18 elements) an image of the atomic structure of the element. We crafted the atomic structure for each element and took a picture to use in our table. 
The table has more columns and elements that the standard periodic table. Mortaza says that the new elements will be discovered in the year 2800. They are the result of a hypernova in a nearby galaxy which has happened in the past. The results of the blast which contains all the new elements will reach the earth in the year 2800. Here is the Excel file to download.
Complex Molecules, a Few More 
Late June - 2021 (1st grade)
Mortaza made up these molecules. I guess he got the ideas of these molecule from the chemistry-related videos that he has been watching recently. He first made it in his chemistry app, and then drew it for me on the board. 
While he was showing me one of his molecules, for some reason, I mentioned nitric acid, and then Mortaza quickly drew the structure of this acid for me.

The reaction of sodium-hydroxide and sulfuric acid 
July 13 - 2021 (1st grade)
We were in Mexico for our vacation, when mortaza created these to explain the reaction between sodium-hydroxide and sulfuric acid.
