Open the link on the next slide of lessonup!.

Step 1: go to 'pick a level' and click on year 5 & 6.

Step 2 : read the following topics 'How light travels ' and ' How we see light' 

Step 3: watch the video.

return to lessonup! of you have done this steps.

P.s. the difficult words are on slide 6

How does light travel?

What is light?

1. Light is a form of energy.
2. Light is what you see when the sun shines.
3. Light is a form of photons.
4. Light is a form of energy made of photons.

What travels the fastest?

How do you call bending of light?

Difficult words from the video

Photon --> lichtdeeltje                                                              Unit --> eenheid 

Visable --> zichtbaar                                                                  Transparent --> doorzichtig 

Opaque --> ondoorzichtig                                                       Translucent --> doorschijnend 

Vacuum --> ruimte zonder lucht of andere gassen
0,1 million miles --> 160.9344 km 

93 million miles --> 14966899 km

Now you know what light is and how it works. Let’s find out what sound is and how it works.

Go to the next slide to watch a video! Return after you watched it.

Difficult words in the video:

Movement --> beweging

Vacuum --> ruimte zonder lucht of andere gassen

Pitch --> toon

What is sound?

Where does sound not travel?

Does sound bend around objects?

How do you call the movement in vibrations?

What do you hear when vibration are moving fast?

What do you hear when vibration are moving slow?

Now we know what sound and light are. Time to know how you can communicate with them.
