A small project with my daughter for her birthday!

Before I left for my holidays, I did a small project with my daughter for her birthday. We did a birthday gift pack for her classmates to create a model of a lung. As one of her favorite TV show is Mister Maker, I thought of asking her to help me in the video

I thought it it was going to be easy creating a “How to make it….” kind of video. I must say that it is quite challenging!  had to do multiple retakes because of my clumsy hands and try as I might, I don’t sound enthuastics…..so my end product isn’t a good one. So hats off to Mister Maker to make such a good program for my daughter to watch! However, I had fun making it with my daughter! 😀

Topics on Light

I will be off on a holiday with family. So I will be inactive for 2 weeks or so.  Before I go, I have done up some more videos on the topic of light. They includes:

1. What is reflection of light and how mirror forms an image?
2. How to draw light ray diagrams for reflection in plane mirror?
3. What is refraction of light and refractive index of a medium?
4. What is Snell’s Law and how do we apply it to refraction of light?
5. What is total internal reflection and how to calculate the critical angle of a medium?
6. What are the image characteristics formed by thin converging lens at different object distance?

They should be useful for some quick revision of concepts for students taking their O levels soon.
