Ever of thought of using science jokes to start your science lessons? It might seem a little corny but it is not necessarily about the joke but more of a way of getting a discussion going over the the meaning behind it using the science curriculum.
Take this one, for example:
A great introduction into chemical formulas.
Or this one...
...as a recap from a previous lesson on atoms and ions.
This next one creates a discussion on the difference between DNA and RNA.
It can lead onto protein synthesis whereby the following can be introduced...
...to start the concepts around translation.
You can even go cute and introduce this one...
...to create a debate about strength of this statement.
The options available are endless and the internet is full of these little gems as a resource. Give it a go. I would love to hear how you went.
