We read a book in a group about life jackets from different centuries.
The story: In 1854, Captain John Ward invented a life jacket using small pieces of cork sewn together. but it is way too hard. So in 1918 Orpheus Newman invented a Kapok life jacket. Because it is made of Kapok, it’s going to get wet and heavy if it stays in the sea for a long time. So during the 1920s Peter Markus invented a life jacket that filled up with air. In 1960 people used synthetic foam to make life jackets. It is better than others.
We answered questions about life jackets.
I found this activity cool, because I learned different things about life jackets.
