Preparation: Put a small amount of bubble mixture and a straw into each jar.

In science it is important to be able to think up good questions to help you learn more. Your team will be blowing bubbles and thinking up good questions about the bubbles. When you have thought up your questions you will decide which ones you might be able to find the answer to by doing experiments.
You will also decide which ones you would need to ask a scientist about. You won’t have to work out the answers to your questions.

Here are two questions for you to think about in your team.
Show and read cue card.

Use this bubble mixture to work in pairs to make bubbles. As you make the bubbles talk with your partner about some good questions that would help you to know more about bubbles. Try to think up about eight questions together. I’ll give you a few minutes to work out your questions in pairs, then we’ll get you together as a team again.

Hand out bubble mixture, notepads and pens. Allow time for discussion in pairs,
then bring students together for group discussion.


Now it’s time to put the bubble mixture aside and share your ideas for really good questions with the group.
I want each pair to share their questions, and the others to listen carefully. Then you can work out which are
the best questions and write them down. Here is a recording sheet for writing your questions on.
Try to write about eight questions.
Hand out answer sheet. Allow time.

Here are some red stickers and some blue stickers. Beside your questions put a blue sticker if you could
find the answer by doing an experiment or a red sticker if you would need to ask a scientist about it.
Hand out stickers.

Commentary:
Because this is a team task, no graph of subgroup performance is possible. There was little change in performance between 2003 and 2007 for year 8 students, but a marked decline for year 4 students.
