Science experiment- breakfast cup

         Making breakfast cup
IMG_5103.JPGIMG_5101.JPG

Today we made a breakfast cup and it tasted so good. When we were making these we were not only waiting to eat it but we were also watching out for the chemical change, and the chemical change was the egg and the bread. The egg was cooked and the bread turned hard like a toast. The temperature change was hot and burning as I held it in my hands, and there was a release of smoke. The chemical change was irreversible and it also formed a new substance which was cooked. Some people enjoyed it but some people did not eat it, but for me it was good. Next time I would like to do it again but better.

Scientific method- chemical change- fire

      Chemical change- fire


Ask a question= What is the chemical change going to look like?, how is the chemical change going to smell like?, how are people going to react to the chemical change?
Construct a hypothesis( make a guess) =I think that it will smell burnt and it might look burnt. People might say wow
Conduct the experiment= There was ashes and smoke coming out of the newspaper when we lit it up, it was black and pieces of the newspaper started to fall off
Record your observations and data colour change,= colur changed to black and the it smelt burnt, it also released smoke and ashes and the temperature change was hot
Analyse information= we lit the newspapers up and it burnt, and a new substance was formed and it was  irreversible
Report results= there was a new substance when we poured water into it, ashes and smoke was released, burnt smell was also released
