Witchy advice: "Follow the 1st CLIL Twin's instructions and don't make him angry!!! He's very nervous... as all Physics teachers! ;-) "

1st CLIL Twin: "To make perfect bubbles you have to follow a recipe: here it is!"
  1. Combine water and detergent.
  2. Stir well, but do not shake.
  3. For stronger bubbles, add ½ cup corn syrup or glycerin, or more detergent.
  4. Experiment with different brands of dishwashing detergent until you find one that works best for you.
1st CLIL Twin says:

"I'm sure many of you haven't follow the instructions properly. So, let's make an experiment: now we are going to try different ways to make bubbles and then we'll record the results in a grid.

THIS ONE BELOW!!!

According to the quality of the bubbles that come out, you will give them these marks:
B.B. = bad bubble,
G.A.B. = good average bubble,
V.G.B.B. = very good big bubble,
E.H.B. = extraordinary huge bubble "

2nd CLIL Twin: Remember this procedure is called experimental method and was invented by an Italian who was not as dumb as your teacher Witch Hazel: the man was Galileo Galilei!!
 

If your mother or your teacher don't want you to spray soap solution everywhere you can use this very clean simulator!!!

Exciting activity!!! In pairs, discover which factors make the highest quality bubbles. Use the grid above to record results and see who makes the best guesses.
Witchy says: Ehi kids! The CLIL lesson is not over: they will come back in a few days to talk about an important Bubble-based Physics topic: Bubbles and surface tension!!!
Keep in touch!!!
