Not that my daughter had any problem in understanding and forming chemical reaction equations.
We still did an activity, just to ensure more clarity about the concept.
Material used were small thermacoal balls and barbecue skewers. Some colors, we used acrylic as it gives a nice shine and texture.
So you start with coloring the balls in different colors. Ensure you have atleast 8-10 balls of each color.
We used acrylic colors to paint the balls in different colors to represent atoms of various elements.
Once the colored balls were dried up, we were ready to experiment with molecular structure.
Here is a sample reaction we tried for methane and oxygen reaction.
The chemical equation is CH4 + 2O2 = CO2 + 2 H2O
And this is how we made the model
It helps to a great extent in gaining clear understanding of chemical reaction.
1. It gives an actual understanding of how molecules break in a chemical reaction to form a new compound.
2. Also how atoms bond in a compound.
I would recommend it to all parents as a must do activity for grade 6 and above students.
Wish I had figured out this technique when I was studying. Let me confess that I was very bad in chemistry. I never got clarity on concepts like molecular structure and valency and bonding of atoms.
