                                ANCIENT EGYPT TECHNOLOGY

HOW EGYPT PEOPLE MADE THEIR HOUSE & BUILDING                                                                     

I search on the google about Egypt technology but then I found that picture on it. It says the technology in Egypt are also tools and house they live in. House in Egypt are build or made out of mud and is very hard to build, but real Egypt people doesn't build it because they already had slaves so slaves build house and buildings for them to live in.


HOW THEY USE THE TECHNOLOGY
They used rope trusses to stiffen the beam of ships. Egyptian paper made from papyrus and pottery were mass-produced exported throughout the basin. The wheel was used for a number of purposes but chariots only came into use after Second Intermediate period . The Egyptian also played an important in developing Mediterranean maritime technology including ships and light house.

There are lot of difference between Egypt technology and our technologies nowadays because we use telephone, laptop, television and etc... and also we have a lot of machine that help carpenter to build buildings but they only use rope and other things.. We use bricks, timber etc.. to build our house but they made their house and buildings by using the mud and rocks..

static electricity (science)

                           

AIM : At the end I want to know what static electricity is about and what is the meaning.

Static Electricity

The right arrow : opposite charges attract

Balloon : Negatively charged balloon

Left arrow : Like charges repel

EXPLANATION :The meaning of the picture above which is the static electricity it what makes your hair stand end when you pull on a polyester T shirt. It happen because of  tiny particles called "ATOMS". Atoms contain even tinier particles called electrons that carry a negative electric charge. These orbit a positively charged nucleus but can break away. The surfaces of some objects such as balloons, steal electrons, from other surfaces and the extra electrons make them negatively charged. We usually think of electricity as flowing through something but when electrons build with no circuit for them to flow along they create static electricity.

So the reason why the balloon makes your hair stand its because electrons is inside the balloon when you see in the picture there are sign those negative sign in the balloon so that called electron. The positive sign called proton so it contains together then the electron and proton mix and moved and then it form 'STATIC ELECTRICITY"


Results
Hair Balloon

If you rub your hair on a balloon electrons are transferred from your to the balloon.This gives your hair a positive charge and a balloon a negative charge . Particles with opposite charges and attracted to each other , so your will stick  to the balloon. Individual hairs will separate out because they are all positive and particles with the same kind of charge repel each other.
