E-Manual ofEggies Symmetry Model Created by A.I.N. TEAM
Misconseption in Learning Symmetry Topic In this Symmetry molecule topic, the main misconseption we identify within students is students are facing problems to determine the rotation for the principal axis, Cn of the complex molecules. But, worry not, let’s learn it together! Name for Our Symmetry Model We have chosen the name for our symmetry model. The name is... “Eggies” The name eggies is chosen because of the components in this molecule. We created the atoms by using the egg nest cardboard. The other factor of why this name is chosen because of the shape of the atoms that reminded us of the eggs.
Mind map of Symmetry concept To help you better in understanding this topic, we have created a mind map for you! Component of Eggies 1. Polystyrene as the central atom 2. Egg nest cardboard as 3 F atom 3. Tissues as 2 Cl atom 4. Straw as the bond To get this mind map in better quality, scan this QR code to download them
1. Attach the molecules based on the geometry you want. Use the straws to confirm its’ axis of rotations present in the molecule 2. Use the hard plastic to confirm its’ plane of reflection present in the molecule 3. Write down the symmetry elements and operations present in the molecule. 4. Determine the point groups based on the symmetry elements identified 5. 1. Eggies can be detachable. 2. Eggies is portable and easy to be brought everywhere. 3. Eggies can form other geometry shapes. Additional straws and hard plastic is provided for axis and plane determination. 4. Features of Eggies Instruction
Activity (Questions with Answer) 1. Find out the geometry shape for this molecule. 2. Create the shape of the molecule with the model. 3. Find out the axis of rotation on the molecules. 4. Find out the Plane of reflection present on the molecule. 5. Find out the Improper Rotation present on the molecule. 6. Find out the point group of this molecule. Based on the molecule, determine whether this multiplication commute or does not commute: 7.
