Hello. Again. This post is going to be about my chemistry unit. Enjoy.
At the very start of the unit we were tasked with making a mind map with questions on what we want to learn in this unit. Below is mine.
Main things I learned this unit:
The main concepts we needed to know for this unit’s project were covalent bonding and ionic bonding.
Ionic bonding:
Ionic bonds on the other hand, tend to between a metal and a non metal. One of them is positive and one is negative causing an attracting effect because they’re opposites.
Covalent bonding:
Covalent bonds when two atoms share electrons in a most common example to hydrogens with one electron each will now share 2 electrons.
Chemistry Stories:
Our main project this unit was our Chem Stories video. It was a partner project and my partner was the tall man Fraser. To pick our partners we did a short activity where everyone got a card with an element on it. You had to try and pair up with somebody that would make your element stable. I got like sodium which had a +1 positive charge and Fraser got like oxygen with a -2 charge. So I needed 2 sodium to complete oxygen’s valence shell.
If you want to check out Fraser’s viewpoint on the unit hit the box below.
This was our finished product. Hope you enjoy.
At the very end of the unit, we were asked to go back to our mindmaps and write down what we learned in a different colour. Below is the revised mind map.
Well that was my Grade 9 chemistry unit summed up. See you soon.
