Ginger Beer and Yeast - Science

Hi.

In science we are researching yeast and ginger beer. We've been instructed to write about the creation of ginger beer and different types of yeast. Afterwards were been instructed to brew ( non alcoholic ) ginger beer.

Ginger beer appeared in the mid 1700's in England, at the time it was created with alcohol, but in the 1920's when it was beginning to be shipped to america, England began to take away the alcohol in ginger beer, and now its considered a non alcoholic drink that can be drunken by all ages. 

There are four types of yeast, bakers yeast, nutritional yeast, brewers yeast and distillers yeast ( also known as wine yeast ), these yeasts have different values and purposes, for example, if you put bakers yeast into wine, the wine wouldn't age as well and it would taste horrible.

Goodbye.

Skittle Chromatography - Science

Chromatography is a technique for the separation of a mixture  by passing it in solution through a medium in witch the components move in different rates.

Aim: to separate the colours from the skittles using chromatography.

Materials

1.  6 Skittles

2.  Water

3.  Petri dish

4.  Beaker.

Process: 

1.  Get your equipment ready and pour 50ml's of water into the petri dish .

2.  Place the skittles into the petri dish around the edges.

3.  Pour water gently into the middle of the petri dish.

4.  Watch as the water removes the dye from the skittles.

5.  Record your results.

Hands On Fire - Science Class

Hello 

Today during science class, the teacher was telling us about lighting our hands on fire using detergent. We were instructed to create a blog post that included the Aim of the task, a few things that will help reducing the cause of injury, The eqipment, we would use and the instructions. 

Aim:  Light our hands on fire
