Natural Science 17th March

REVISION VIDEOS
Have you finished correcting AAAAAALL Unit 4 stations? You must be an expert now!


Attention!! I.V.M. pointed out there is a mistake in the correction of  Station 6. This is how the Changes of State in Matter should look like.
As you can see:
GAS to SOLID = deposition /sublimation / reverse sublimation
Watch these videos to continue learning.
Comment if you learnt something new or if you have a super important question for me. You don’t need to understand 100% of these videos. 70% is OK!

    Hi violeta
    I have a question:
    If you put Milk and colacao for example, first it is separated but then when you remover it and you don't see the component's.
    That would be homogéneous or heterogéneous?

    1. Amazing question!
      Heterogeneous: before you mix it, when you can still see the milk and the chocolate separately.
      Homogeneous: once you mix it, when you can't distinguish the two components. It's a SOLUTION. (but the two ingredients are still there!!!!)

    1. It's "acetic acid", a type of acid. You can research online if you're interested, but that is very advanced.
