See, Think... Wonder

Miss Whittaker has made us these great posters:

and that's what we've been doing.
Together we looked closely at this image:

We saw a lot of things:

Then some thinking... Tibo thought it looked like a competition. One man looked Asian and the other European, and it looked like the woman was the judge. Felix thought the woman looked like a god. Kirill thought she looked like a Fairy of Mathematics.

Next we got into pairs and wrote what we saw and thought:

 

 

 

 

Next week we'll see what questions the picture brings to mind...

Roman numbers and an abacus

We've been looking at how Roman numbers work.

When it gets on to the big numbers, as B. said, our numbers are easier:

The Romans maybe found them hard to use too.  They didn't have electricity, so they didn't have a calculator.

Instead, some of them used an abacus:

Strangely, it's very similar to the abacus used in Japan:

We watched the first few minutes of this to see how to count on the abacus:

Then we had a look at an online abacus:

OXYGEN discoverd by ......

Carl Wilhelm Scheele

Born:- 9 Dec 1742 capital Pomeranie
Birth place:- Stralsund Pomeranie Germany
Died :-21 May 1786
Location of death :-Koping Sweden
Cause of death:- unsprcified
Gender:- male
Occupation:- Chemist
Nationlity :-Sweden
Executive Summary:- Discovered Oxygen Chlorine Manganese;

Oxygen was first discovered by Swedish pharmacist Carl Wilhelm Scheele. He had discovered it by about 1772. Scheele called the gas “fire air” because it was the only known supporter of combustion, and wrote an account of this discovery in a manuscript he titled Treatise on Air and Fire, which he sent to his publisher in 1775. However, that document was not published until 1777. Meanwhille, oxygen was also identified by Joseph Priestly in 1774. Priestly discovered a colourless gas from heated red mercuric oxide. He found this gas was highly combustible. He called it dephlogisticated air. Priestly shared his discovery with the French scientist Antoine Lavoiser. Lavoiser was able to show oxygen supported animal life respiration.

Discovering very big and (very small) things

When Galileo made his telescope,

He discovered things never seen before.

When Herschel made his huge, 12 metre long telescope, he discovered Uranus.


Have a look at this film, Powers of Ten, that shows some of the very big things that we then discovered:

Dmitriy Mendeleev Presentation

The Russian chemist who discovered the periodic table of elements

Born: 27 January 1834 - Died: 20 January 1907 

Mendeleev is one of the people, who are making me really proud of my country. He had build the foundation of modern chemistry! The periodic table changed the world forever. Without it, chemistry would look pretty much like in middle ages. 

Dmitriy HAD made a difference to a world. The tale says that Mendeleev saw the periodic table in his dream. In the periodic table, elements are sorted by their atomic weight. And if we know the atomic weight of an atom, we can pretty much tell his abilities! With the periodic table, we can say what abilities will have the elements that we haven’t discovered yet! I should say thank you to him! 

Actually, Mendeleev is so famous, that 101h element in his table and crater on Moon!

Kirill's Christmas Video

Hello!

Watch my video about Christmas here!

Hope you'll enjoy it!

(I made it all by myself in IMovie app including videos and pictures from IPhotos app!)

Thomas Edison

                                                  
                               Thomas Edison´s incredible inventions!

 Cell phones, movies or digital cameras were all early versions invented by Thomas Edison. At school Edison was always daydreaming so, one day his mother decided it was better if Edison worked at home. His mother taught Edison every thing she knew. When Edison grew up he invented the electric light bulb. Before this invention people had oil lamps, which were very dangerous.

VISIT TO LUCHON

On 1st January, we went to Luchon. Luchon is a beautiful city in Midi Pyrenees.

It took 2hrs to reach there by car. First we went to tourist office to get some information about the places to visit in Luchon; then we had a walk in the city centre.

There are beautiful houses in the city, the roof of most of the houses in Luchon  Valley are grey. There are many shops in the city centre. 

Then we went to a ski resort, Superbagneres. We reached there by cable car. When I was sitting in the cable car I was bit scared and excited at the same time. After some time we reached the top of the mountains.

The view of snow covered mountains was extremely beautiful. The sun was shining brightly and it was a wonderful day. Children were sliding using sledge.

We clicked many pictures with the mountains. We played with the snow and also slide from the snow slope. We had lot of fun.Then we had our lunch. We also walked on the snow covered mountains. 

 

Then we came back to Luchon valley by cable car. 

It was really a fun trip. I enjoyed a lot.

Who is Jacques Cartier ?

The Teachers' Study Room

Act 1

Watch the video:

What do you notice?
What do you wonder?


How many carpet squares would be needed to cover the whole room?
What is a number that you're sure is too small?
What is a number that you're sure is too big?

Act 2

Notice that the Teachers' Study Room's floor is not a rectangle. It's a kind of L shape:

It looks like, from the plan that this is its shape, measured in carpet tile lengths:

Show your thinking when you work out the number of carpet tiles to cover the room.

Act 3

Extra

Next door is the staff room:

 The staff room is an L shape too. Here are some of the walls measured in carpet tile lengths

Work out the number of carpet tiles that would be needed for this one if the floor was completely covered in tiles. Show your thinking.

Cubes on paper

Act 1

Watch the video:

What do you notice?
What do you wonder?








How many cubes would you estimate would cover the paper?
What is a number that you're sure is too small?
What is a number that you're sure is too big?

Act 2

What are the measurements of that paper?

It's called A4 paper. The cubes are 1 cm wide.

Its length and width measured with Cuisenaire rods. The orange is 10 cm long.



Now you can work out how many little white cubes would cover the paper.

Act 3

Here it is measured with rods:

Extra

You can see the paper cannot be measured exactly by Cuisenaire rods. The paper and the rods and hundreds don't fit exactly; the paper is a tiny bit less long than we've measured:

Actually, A4 paper is exactly 29.7 cm long and 21 cm wide.

Can you work out the exact area of the paper?
