Make an alarm for Katie Morag

I made this as part of our work linked to Katie Morag. She wrote a letter to the class, asking for their help. Her cousins were visiting and she wanted an alarm for her bedroom so that she would know if they went in there. 'science problem' accompanies 'buzzer problem' and 'problem part 2' goes with 'KM buzzer instructions child 2' and either of the accompanying word sets, according to ability. We had a lot of fun with this! Look at the second lesson first, to make sense of what you have to do.
