I loved the simplicity of this activity. Plastic dinosaurs, animals and shells frozen in water, placed inside plastic boxes for the scientists to excavate. I really struggle to find activities that work for both Lucas and the twins, but this held both biggest and tinygirl’s interest (tinyboy slept through it!).
Due to over-freezing, the blocks took a while to start melting. This provided an excellent opportunity for learning, as we discussed what can melt ice. Lucas came up with fire (conveniently the wood burner was going!), using our hands, pouring warm water over the block, and using tools. We tried all four of these and talked about how they compare.
Tinygirl had a fantastic time touching the ice, depositing her lunch into the box, and playing with the tools.
