Go out and enjoy the snow! Can you catch a snowflake? Find something dark (a piece of black paper or item of clothing will help). Look closely at the snowflake shape. They really are amazing. I have attached a link that shows you some zoomed in snowflake pictures for you to enjoy looking at.
Why not collect some snow in 3 different containers. Place these in different places. Which melts first? Why do you think that one melted slower/ faster?
Why not be creative and make some paper snowflakes. Use the link below to help you. Just follow the first part with white paper. Maybe try cutting different shapes to Mr Maker and see what happens.
