In our next science lesson is about changes in materials.We did our experiment about changes in materials.Our teacher grouped us to 4 member. Im with Marcella,Nayra,Isa and Keven.We find out about physical change or chemical change experiment.And between reversible to irreversible.We use vinegar,sugar,butter and much more.We try to use candle so we heat the sugar its physical change and its reversible.The sugar looks like caramel when its burn.But when the sugar is cooled its not became back to normal crystal again.This is the example of my picture with my friend experimenting about changes in materials.

And we mix vinegar with baking soda.It smell very bad.And we experiment about butter burned we can show that a butter it is chemical change because it can't change back to its normal state.But i still enjoy my experiment with my friends.I wish i could experiment much more about the other lesson with my friend.

 This is when we discuss about changes in materials.With other friends and the other group.And we discuss between chemical and physical changes.And,between reversible and non-reversible things or maybe some food when we baked like example the egg that is chemical changes and its non reversible materials.
