1PRIMARIA: Exploring sound waves with salt

EXPERIMENT: EXPLORING SOUND WAVES WITH SALT

       SCIENTIST: Íker Tantos López (1A)

You can see sound!! 👀👂

The loud music produces noise which vibrates. This makes the air vibrate as well, producing waves.

When the waves hit the bowl, the bowl vibrates, making the salt jump about.

Materials:

Glass bowl

Portable speaker

Rubber band

Salt

Plastic wrap

Materials:

Pepper

Water

Soap

When we use soap the germs move away. This is why using soap is so important!!

1PRIMARIA: Light Refraction experiment

EXPERIMENT: REFRACTION OF LIGHT IN WATER

SCIENTIST: Íker Tantos López (1A)

Is it science or magic?

Let´s take a look!!

When light passes from one material to another, it can bend or refract 😉

In the experiment, light traveled from the air, through the glass, through the water, through the back of the glass, and then back through the air, before hitting the arrow. Anytime that light passes from one medium, or material, into another, it refracts.
