In our year-long Unit of Inquiry ‘Sharing the Planet’ we, in EY2 RR, have been researching animals that hibernate and those that live in the Arctic. We have also been looking at the relationship between animals and people.
We compared and discussed how we, as people, stay warm in winter and the ways in which animals, in the Arctic, stay warm.
These are the questions that helped us start our discussions and thinking:
How do we keep warm in winter outside and at home?
- Walker: We cover ourselves with a blanket.
- Anika: We need a scarf, hats and gloves.
- Zane: Snow boots.
- Wren: Neck warmers and warm clothes.
- Annabel: At home we have a fire to keep us warm
How do animals stay warm in winter?
- Nicolas: They have hot skin.
- Alex: They have fur.
- Walker: Some have a special skin to keep them warm.
- Amy: They have special oil in their skin, which keeps them warm.
After these discussions, which demonstrated what the children already knew about the topic, we concluded it would be fun to do a science experiment to discover how it would feel to be an Arctic animal swimming in icy water. This experience would not only help in the children’s understanding but also give a practical hands-on experience, which they would love.
First, each child put their bare hands in a tray of ice. We counted to see how long they could hold it in there. Some could keep their hands in the ice until we counted to 75 and we had to stop them.
- Zane: It is really, really very cold.
- Ffion: It is slippery and cold.
- Annabel: It is freezing
- Ffion: It is not cold now. I can keep my hand in here for a long time.
- Edward: I like it now. My hands are not freezing. Mrs. Rao, do the animals have the sticky thing (fat) on their body?
- Walker: Yes, animals that live in the cold places have special skin and also fat to keep them warm.
- Edward: The cream we have on our gloves, I think, helps the cold to just fall down.
- Mrs.Rao: What do you mean?
- Edward: I think now, that the cream protects them from the cold.
The children agreed that their bare hands felt very cold but with fat it felt warm.
This experiment helped the children to become scientists, make predictions, observations and understand how the layer of fat, that some animals have, keep them warm in winter.
