This is our second science lesson on materials. When you open the link to the lesson you will recognise the lesson from last week. Please start at 7min 13second. In the lesson the teacher asks you to click on a link to a song. That link is on our class page and on the worksheet. There are some fun challenges to try today. At the end of the video lesson the teacher asks you to send your challenges to her. It would be better if you could send any photographs of your science challenges to me please.
