Today I and Lena and my son explored the area around Boreehaugene and followed the track of the Vikings to see what type of activities we can find for play and learning with children
We first drew a map that we followed
We drew a map for what – how – why use interesting places with children.
Why does wood float?
Because wood is less dense than water. That means that the same amount of water is heavier than the same amount of wood. A stone, for example, is denser than water. That´s why it sinks. Also, ice floats because the density is lower than the density of water as water expands when it freezes. Most things that float have a lot of air in them what makes them light and gives them buoyant.
