Thank you for helping Sir George find a perfect spot for his castle. He is thinking of what materi al he should build his castle out of. Can you help him? His castle needs to be really strong and not get knocked down by any angry dragons! Can you build a strong castle for Sir George to live in? What materials could you use? You could use recycle material, Lego bricks, straws, card, glue sticky tape etc. Challenge : Can you draw, label and write about your castle ? You could test if your model is strong enough by asking an adult to try blow it down with a hair dryer.
