Helen likes learning new things all the time and
Daddy's friend Peter shows her that you don't always need a
laboratory to learn. All you have to do is observe the things
around you and watch how they change and transform. By observing and deducing, Helen learns what happens to water
when we freeze it, what happens to ice when we heat it and
where the juice we drink comes from.
