What are hydraulics, hydraulics are a system that uses pressurized liquid to power things such as engines the hydraulics put pressure on a small amount of liquid to generate lots of power, they where made in late in the1700,s by joseph Bramah he used to work on practical things by following pascals law and eventually after practicing and trying to make hydraulics he succeed.
How do they work, lots of people know where to find hydraulics (eg) cars and trucks but lots of people don't actually know how they work and what they do to power the engines. heres how it works there are four main parts of the machine the first part of it is The Reservoir this is where the liquid is held it also transfers heat to the rest of the machine and helps remove air and moisture made by the liquid.
the second part of the machine is The Pump it moves mechanical energy into the machine it does this by moving the liquid from The Reviser although most of the pumps mainly do the same thing some of them are a different type such as piston pumps and gear pumps.
The third part of the machine is the
valves they start and stop the machine and areas where the liquid moves and thats about all they do.
And the final part of the machine is The Actuators this part of the machine is very interesting it takes the hydraulic energy and transforms it back into mechanical energy for use again there are also different types of actuators that are used for specific things anyways that is how hydraulics work and what they are used for.

marbles science investigation
What happens when we slowly put marbles into the second cup when the first cup had ten in it
well at first it did nothing however when the second cup had seven marbles in it somehow balanced the two cups and then when we did it again both cups where balanced with 4 marbles in each
I know why the second one worked it worked because there where the same amount of marbles in each so it balanced it out.
however, the first time I do not know how it worked some marbles must of weight more than the others so it was balanced

Ancient Egyptian Inventions
here are some inventions and other things that we use lots that were created by the Egyptians.
1. Writing, ancient Egyptians write things in a very different way to us however we still use this all the time.
2. Papyrus sheets, this was the closest material to paper at the time other countries did not have it and instead used stone clay and other things.
3. Black ink, Ink is used all the time in things such as printers or pens but did you know they were made in ancient Egypt.
4. The ox-draw Plough, The ancient Egyptians where the first people to invent plowing to plough their farms.
5. The sickle, They also invented the sickle for farming to help them.
6. Irrigation, they may not have invented irrigators however they used canals to take water from the flooding Nile river to their farms.
7. They invented the calendar to tell when things were such as festivals.
8. they also invented clocks so they knew what time it was.
9. they even invented police to help look after and protect them when all of the other countries did not know every country has police.
10. They invented surgical inventions to help injured people and help fix their wounds.
11. They even invented wigs and cosmetic makeup.
12. We all know this one the Egyptians invented mummification for when people died there.
13. This might surprise you but did you know that they invented toothpaste.
They also invented many other thongs that we use today.

My Boomarang blog
What I have learned about boomerangs
Artwork, The artwork on boomerangs can mean a lot of things one of these things is the gods that the aboriginals believed in and they painted them in forms such as animals trees and plants they did this because they believed that the god where inside of the things they painted on the boomerangs.
What where they used for, Boomerangs were used for a variety of things such as games and competitions they were even used for hunting they were later used for even more things when the Europeans arrived because they started changing the shapes of them and making them out of different materials.
Different shapes and materials they where made of, when the Europeans arrived in Australia they started making different types of them with new materials and new shape sometimes these new materials would make them lighter while others made the boomerangs heavier they also made them and new shapes which helped return better and go further, boomerangs where also made in different sizes some where small for games while some large ones where made for hunting.
how they helped aboriginals, boomerangs helped the aboriginals in many different ways including hunting and games and sport even battle clubs and fire starters and musical instruments there were also many more things that boomerangs were used for.
