Brains of the Month: Sir Isaac Newton


There are lots of super brainy people out there, without these clever clogs we wouldn't have what we have today. So, every month we will have a different 'Brains of the Month' from scientists to mathematicians, right intelligent noggins.

This month we bring you Sir Isaac Newton.



I bet Isaac was really good at pub quiz's. You would definitely want him on your team. He is so clever, he invented gravity, well discovered the theory of gravity.
Here is what happened:

Isaac was enjoying an afternoon in the sunshine, when an apple fell on his head.

A quote Isaac famously said, meaning someone who discovers by building on previous discoveries.


What a brainy fellow, we give him 5 brains out out 5 for his contributions to science.

Science Facts Thursday: Changes of State


It's science facts Thursday again!!

Ever had a chocolate bar that has melted to a mound of mush? Or attempted to make homemade stock to find all the water has vanished? What's going on? Well, science has the answer.

All substances can take form in any of the three* different states, solid, liquid or gas. However, at room temperature some of these will be solid and some will be liquid or gas. To change this you need to change certain things. Temperature and pressure.

Changes of state

Pressure and temperature are what effect the change of state. Air naturally presses down on Earth, this is called atmospheric pressure.
The higher up you go, the lower the atmospheric pressure, so boiling points are lower as it is easier for particles to move about.
The atmospheric pressure is why your ears 'pop' when you go up in an aeroplane.




Don't forget to join us next week for more science facts!

Keep your eyes peeled at Cosmos and Crayons, we have some exciting new post coming soon! Including Sunday Cut Out and Keeps, mini craft projects for you to print out and complete at home :)

Science Facts Thursday: The Kinetic Theory

It's Science Facts Thursday again!

Last week we had a look at the structure of an Atom, this week the behaviour of particles within an atom.
Kinetic theory explains the behaviour of particles in solids, liquids and gases.



A substances is classed as a solid liquid or gas depending on what state it is in at room temperature,( 20 Degrees Celsius).

Join us next week for more science facts!

Scouting for Ad Buddies

Help spread the word!
Cosmos and Crayons are on the lookout for fellow bloggers to swap ads with.
We are still fairly new to blogging, and still getting our heads around all the jargon, so we are offering two sizes to choose from free for a month, ideally if you can offer an add in similar size on your blog.

Currently we are taking ads in the following sizes.

250x150 Pixels

If you need the Cosmos and Crayons ad in a different size to fit on your blog, let me know and I will make one up for you. 
So, if fancy an ad swap, pop me an email at chopstitchcrafts@gmail.com

Science Facts Thursday: The Atomic Structure

Don't trust atoms, they make up everything!

It's science facts Thursday! A slightly delayed one, since we have been enjoying a little break and have been on lots of mini adventures, including a trip to the Museum of Science and Industry to see an exhibition on brains! More on that another time..

..This week we look at the structure of an atom. What is an atom? Everything is made up of atoms, everything, including your breakfast cereal to the smell of roses. They are super tiny too, so super tiny that in a single grain of sand there is close to 78 quintillion! (That's 78, 000, 000, 000, 000, 000, 000)

So what does an atom look like?

Not to scale.

The diagram above shows the structure of an atom. We used Carbon as an example. Carbon has 6 protons,  6 neutrons and 6 electrons with 2 shells.
The number of shells an atom has depends on the number of electrons.

This is where is gets complex. There are things called isotopes. These are variations of atoms of an element. For example, the diagram above shows a regular carbon atom, an isotope of carbon is 'carbon 14' which has two extra neutrons! This carbon atom is unstable and is radioactive! Think of it as the naughty identical twin.




Protons and Neutrons are best buds, and hang out in the nucleus.


The positive charge of the protons and the negative charge of the electrons in an atom keep everything stuck together by attracting one another. They also cancel out the electrical charge making an atom neutral .


Next week we look at the Kinetic Theory! In the meantime enjoy this song about atoms. ♥
