Playing with molecules!

Hello students!!!

I have checked your works and they are great!! I love them. Keep on working because you are doing it very well. CONGRATULATIONS

The lockdown does not allow us to see each other in class but we can go on with experiments and investigations.

Do you remember when we were talking about molecules? When we were playing with molecules in class?

Everything is made up of matter (molecules) and we can find matter in three different states: solid, liquid and gas

Solid molecules are packed together

Liquid molecules are a little bit separated 

Gas molecules are very much separated.

That is why we can take solids, but we cannot take  liquids and.... definitely...

 we cannot take  any gas !!!

These are the three states of matter!!!

Do you remember what happened if the temperature of the matter (in water) changed?

Time to experiment!!

In the next experiment we are going to make a home-made water cycle.

MATERIALS:

. Plastic water bottle (or glass bottle) TRANSPARENT

.  Warm water

. Markers (It is better if they are permanent but if you do not have them, use the ones that you have)

PROCEDURE:

1. Take the transparent bottle and draw clouds , sun, water and land on the sides of the bottle.

2. Warm water and add the colouring food (if you do not have it, it is not essential) and them, pour it into the bottle

3. Close the bottle and place it by the window.

4. Wait for 2 or 3 days.

Do not forget to follow the scientific method!!!( with all the steps)

Activities: answer the questions:

. What is evaporation? 

. Has the water inside the bottle evaporated? How do you know?

.What is condensation?

.Has the water inside the bottle condensed? How do you know?

. What is precipitation in the water cycle? 

. Can we find the precipitation process in the bottle? How?

.What is melting?

. In the “real” water cycle.... could you please tell me an example where we can find “the melting process”?

. In the “real” water cycle... could you please tell me an example where we can find “the solidifying process”?

. What happens if the temperature changes in : evaporation, condensation , melting or solidifying?

You can do the activities in your notebook and them send them to me with the scientific method and some photos.

Deadline: May 15th

Also and ... this is not compulsory... you can send me a video with your presentation.

  I love your videos!!!!

Good luck to everyone!!!!

 You are doing it great, so proud of you!
