1. '''Structure of atom'''

Hand over the [[:File:Observation sheet - understanding atoms, conductivity, electricity.odt|observation sheet]] to students and ask them to fill it along as they progress through the different activities

Ask students in a group to come up with a single drawing that represents a possible model for an atom, and include a list of information about the atom about which they are all in agreement. (This is to get a sense of their prior knowledge)

Explain briefly the concepts associated with structure of an atom - what are protons, electrons, neutrons, nucleus, orbits

Open the 'DC circuit lab' simulation and ask students to observe what all they see on the screen. Demonstrate how the components can be moved around and connected.

Once the bulb glows, click the checkbox that shows electron movement. Show simulation/video of electron movement in conductors and insulators and explain the concept to the students, connecting it to the structure of an atom.

Give them different objects to test and ask them to classify based on their observations. Students can also pick up stuff from their surroundings like leaves, rocks, and test those as well.
