Tuning fork experiment 

Hi, guys welcome back to another blog about science.

 

So in class, I had a question it was “What causes sound?” In the experiment we saw what happens when we put a vibrating tuning fork in water.

My materials were a tuning fork, cup, tape. Then I tested it.

I realized that the sound waves stayed in for a bit. Then when I put it in the water the water vibrates with the vibrating tuning fork the water gets triggered like a gun and like a gun it fires and The molecules separate and go its own direction.

Science – light experiment

I am writing a blog post about my work in science about Light.

Here are 3 facts I learnt in class about….

  • When you put a pencil in water the pencil curves because your eyes have to see a straight line. this is called refraction.
  • The moon is a reflection of the sun and stars are a reflection of the moon.
  • Opaque is all darkness and makes a shadow, transparent is see-through, translucent lets a little light through.

In class, we did an experiment to investigate this topic. The experiment was called The reflection of light.

Now I will explain what we did:

I researched reflective clothing at home and presented it to the class. Here I am:
