In 1ESO we are working on sound and its properties. During the last lesson we have worked on how the ear works and this crossword can be a good warm up activity for next session.
Besides, I have watched this amazing video and I want to share it with all of you.

One last thing, I've found this interesting jeopardy game and it can be really useful to review some of the contents worked during the lesson (I'm sorry, I don't know who has created it)
