Science 8 – Today was one of those rare days when your students actually put an iPad to good use. I get so frustrated with the concept of the iPad (and Chromebook), as they are simply not good investments for schools that have science classes. However, today the kids go to use a phet simulation that works with HTML5, which means it works with the iPad.
The activity was very simple. The students played with the simulation which had them mixing the three primary colours, and using filters to block out colours. From their explorations the students were able to clearly say that white light is a mix of all other colours, that filters block all colours except that the colour of the filter itself, and that all colours can be made from mixing red, blue and green. Next day we will look more closely at the electromagnetic spectrum, light spectrum, and wavelengths. From that the students will have more complete picture of what a “colour” is.
