The simulations are customized for use in primary school and secondary school. Feel free to download and remix. You can use them for inquiry-based activities or allow the students to conduct experiments using the simulations. Do feel free to ICON me at firstname.lastname@example.org if you need any modifications. I will try to see how I can help you.
Here are the simulations I have done so far and their original authors (if applicable)
Have created a simple simulation on shadow. This can be used to understand how the length of the shadow changes. There are 2 graphs to depict the situation. You can get the students to guess what the graph means
