2. BREAD

3. Bread Who invented bread? Actually nobody knows who invented bread. We have done lots of research but have not found any information about who invented bread. How old is bread? Bread is about 30.000 years old. It is one of the oldest foods in the world. What are the main ingredients of bread? The main ingredients are Flour, water, yeast and salt.

5. WIND (EARLY)

6. Wind What is wind caused by? Wind is caused by air flowing from an area of high pressure to an area of low pressure. What is wind used for? Wind is used for windmills, Clipper sailing ships etc. These things used wind as an energy.

7. Wind What are Windmills used for? Mainly grind corn and other seeds to make flour for making bread and to pump up water for irrigation to grow crops. With these crops that we grow, we can make flour. This method has been used for lots of centuries. Who invented the Windmill? The windmill was invented in 634 for a Persian caliph and was used to grind and crush corn and draw up water for irrigation. Mills had six-twelve sails covered in fabric or palm leaves from palm tree from where they cut the leaves from.

The Clipper Ship was the fastest sailing ship of the 1850s. The Clipper ship was used for carrying expensive cargo’s like spices and tea etc.

10. Wind How long were Clipper sailing ships used? The Clipper sailing ships were used for around 2 decades (200 years).

11. Wind What is wind power? Wind power is what we get by controlling and make use of the energy of the wind. How long has wind power been used? Wind power has been used as long as humans have put sails into the wind.

12. STEAM

13. Steam What is steam? The vapour into which water is converted when heated, forming a white mist of tiny water droplets in the air. What things can you do with steam?
