In these Science Snippets, I provide write-ups and a few short videos on activities that are effective, easy to do and that won't take too much time to prepare.
Education, in essence, is the sharing of our experience and knowledge.
It brings me great pleasure!
Science Demos that Teach:
No3 Does Newton's First Law hold true in the real world?
Newton’s first law is often thought of as basic and obvious. But is it really so? In this discussion I use two toys, a ramp walker and gravity walker to explore. The walking camel toy I have had since my Year 1 year (so it is rated as antique!) and still find it an engaging demo!
Measure the average speed of a moving object with your phone
The quick measurement of the average speed of a projectile or object can be very useful, especially in engineering when analysing the impact of design changes. Do you require special equipment? No! You have it in your hands – your mobile phone, packed with useful sensors.
Chemistry activities with Toys in Middle School level
Light: Persistence of Vision
There are numerous oscillating objects, electromagnetic waves and flickering lights out there that cannot be observed by human sight. Our sense of sight is just not able to perceive and detect these fast changing images. In this snippet I will show you an easy way to expose this “secret world” to your students using a solar panel and speaker.
