The content of the first two lessons of Waves covered in one.
Go through the information about waves whilst students complete the first page of the booklet. They are then left to complete the rest of the booklet themselves, using the first page as a guide.
Finish off with getting the students to complete certain waveforms when given specific sounds
Using ramps and cars the students plan their investigation using the planning sheet, and then carry out the investigation. This can all be done in one lesson.
I then set them the task of writing up the investigation (using the level ladder) as homework, but could be done in a subsequent lesson
Use rulers to demonstrate amplitude and pitch. My starter was me playing happy birthday with a 15cm ruler, and Jingle Bells (it was December when I planned this)
The lesson looks at the two theories of the universe being created - Big bang and steady state.\n\nThey use the key cards and split between inferences and observations then use them to decide which is a better model and why
Worksheet looking at waves travelling through different media.\n\nStarter used a bell jar.\n\nThis is a practical based lesson with three different activities
Practical activity.\n\nIn pairs students pick a type of ear to make. They then stand near the sound source that is included and walk backward until they can no longer hear the sound. The sound needs to be very low, along with the class being quiet.\n\nTwo elephant ears should be the best.
Include demo's such as:
1. One nail bursting a balloon, then bed of nails not bursting the balloon
2. Crushing can (youtube)
3. Inflateable marshmallowman (youtube)
