Activity set – weather: building on from a previous lesson investigating shadows I would use the ESERO hot and cold resource. After Recapping what we had previously learnt about the sun and shadows I would ask the children how do they know the sun gives off heat to prompt an investigation into whether it is warmer in the sun or the shade. After setting up the ice cube experiment, the children would make their predictions before watching the ice cubes in the bowl in the sun and in the shade. The when is it hot or cold activity and the end of this resource is a great transition into subsequent lessons on what clothes to wear and designing a coat whether for themselves or a teddy. Which also ties in with materials.
