What is yeast?

This term (term 2) we are learning about CHANGE - chemistry around us. We are looking at reversable and irreversable changes. So far we have baked bread and we have made jelly. In this example we looked at "what is yeast?" and how yeast works to make dough rise. We loved making and eating our bread.

Mum and Dad ask me about how I made the bread;

We also made jelly. This was fun, we learnt that jelly can dissolve in cold or hot water but it will dissolve faster in hot water because heat makes the parts of water move faster. Our jelly pictures will be uploaded at another time: sorry.
