Magnetism (6th Grade)

Good afternoon!

Magnetism is our current learning topic. 6th Grade pupils are experimenting with this force and trying to understand how it works.

Last week we learnt what the magnetic field is: an area around a magnet in which there is a magnetic force. There are invisible lines that go from the north pole of a magnet to the south pole (or the opposite).

By performing an experiment, we could see these invisible magnetic field lines. All we did was spreading out some iron fillings onto a paper, which was laid on a bar magnet. Then, we gently tapped on the paper and...

The next day, we created some temporary magnets:

STEM Challenge #12: Floating boats

Hello!

3rd Grade pupils have a new STEM Challenge to show you:

"Design and build 2 different floating boats for capacity".

These were the materials provided:

Students, in small groups, had 30 minutes to build 2 different floating boats.

Once they had built the boats, they had to test their capacity, measured with cents.

It was incredible how they managed to build boats designed to hold as much capacity as possible:

A cool look at the sky! (4th Grade)

Hello everyone!

There are many amazing Apps that show us how the sky really looks like.

Fourth grade pupils tried one called Sky Map:

They could find different stars, constellations, planets and even galaxies!

It is very easy to use and you can spend hours and hours investigating the universe. We strongly recommend you to download this app or another (there are many more and most of them are free!).

Density experiments (5th Grade)

Hello, everyone!

In 5th Grade we learning about MATTER and its properties: mass, volume and density. 

After calculating the mass and the volume of some solids and liquids, we moved to density. 

"Density is the relationship between mass and volume".

Fist of all, we compared a rock and a piece of cork from similar sizes. We all agreed that they occupy the same space (they have the same volume) but the rock is heavier than the cork (it's got a bigger mass). So, we learnt that the rock was DENSER that the cork.

Then, we moved to liquids. 

1. First, we observed different liquids that have the same volume but weight different.

2. Then, we put the same quantity of water, honey and vegetable oil in 3 different beakers and we poured small objects inside, in order to observe if they floated or sank. Of course, we made predictions first!

"The denser a liquid is, the easier it is for an object to float on it". 

So, we could order the density of the liquids (from most to least):

1. Honey 

2. Water

3. Oil

3. We mixed them up and we saw that liquids with different densities don't mix.

4. Then, we tried to mix hot and cold water, to see if they have different densities (they do!):

5. And we did the same with salty or sweet water:

6. Finally, we poured all the liquids we saw at the beginning of the lesson into a container and we could check that...

"Liquids with different densities don't mix".

Now, it's your turn! Why don't you try it at home?

Thank you Maryam, Rihab, Andreea and Elena to share with us your experiment done at home!
