Hi crazy little scientists!At the end of this unit, you will discover a special secret message waiting for you. Pay close attention, do your best, and enjoy the journey because every activity will help you get closer to the surprise.Good luck and have fun learning!

light properties
What' s sound?
Vibrations of waves through a medium (solid, liquid or gas). It can' t travel through a vacuum.
- Loud sounds are produced by: large vibrations
- Small sounds are produced by; small vibrations
Challenge 2: order the sounds from the loudest to the quietest
Challenge 1: why do sound move faster through water than through air?
Challenge 3: which living things use echoes to navigate or hunt?

What´ s light?
Form of energy on the elctromagnetic spectrum that is both a particle and a wave and travels in a straight line

light properties
REFLECTION
When rays aren´ t absorbed by an object and bounce off instead
For example in periscopes, mirrors, water, etc.
Smooth surface
Rough surface
(reflects in the same direction)
(reflects in all directions)
REFRACTION
When the light travels from one medium into another (air- water).It passes through a medium with different density, it changes direction
For example: rainbow, lenses, fish bowl, etc.

Heat vs. temperature
HEAT
TEMPERATURE
- Electrical and chemical energy can be transformed into heat (artificial heat sources) and there are natural heat sources such as the sun. We also take heat from inside the Earth (geothermal energy)
States of matter
Expansion
As matter is heated it will expand. The particles around move faster
Heat can change the states of matter
Contraction
When an object is cooled molecules move slower and closer

Cogratulations, you did it!
By mastering light, sound and heat you discovered the secret message: You are 96% CHON!!! CHON; carbon (C), hydrogen (H), oxygen (O) y nitrogen (N), elements that bring life to our planet. Each of your cells is made of those elements. As a master of science, the future is now in your hands!

- It travels in straight lines called rays
- It doesn´ t need a medium to travel and can´t pass all materials
Found in nature: - sun - Northern lights

- Light is faster than sound
- It travels around 300.000 km/ s

1. Motorbike
2. Cleaning vacuum
3. Birds
Because in water, particles are closer together. Energy vibrations are passed quicker from one particle to another compared to air particles
- Humans can only see a small amount of visible light
- It appears white but it´s made up of many colors
- The light can be absorbed, refracted or reflected in contact with objects

Found in nature: - sun - Northern lights
- Movement of particles within an object.
- It flows from hot to cold
- Measure of energy. It measures how hot or cold something is.
- The higher the temperature is the faster the particles move
