Bubble week activities continued

Writing and Judging the speech bubbles competition.

Wednesday 26th May

yesterday's work had thrown up yet more questions.....

•Can you poke something wet into a bubble without breaking it? (Eva observed Devon poking his bubble blower into the bubble, she wondered if she could put her finger into one without breaking it. ) We decided to test using different thicknesses of 'wet pokers'.
•What happens if you put a bubble in the freezer? (Alfie)
•Will bubbles last longer in the shade/or the sun? Louis D)
•What happens if you prepare your bubble mixture a long time in advance- will it make better bubbles? (Ms Spyropoulos)
•Why are some food colourings, better than others at colouring bubbles? Is it to do with the ingredients in the food colouring?
•What happens if we put engine oil in our bubble?
•What about perfume? (Toby) shower gel (Alfie).
•Does sugar make a difference? What about glycerin? (Sugar)
•If you blow harder do you get bigger bubbles? (Jenni)
•How many bubbles can you blow in one go? (Emily)
•How much does a bubble weigh? (Josh).

Then
Literacy- we wrote some captions in speech bubbles and then had a competition to see who had, had the best ideas. (We all voted!)
Art-and Design- We started to design our own 'perfect bubble' posters using the things we had found out yesterday. Also we designed bubble machines.
Some whole class experiments we didn't get time to do yesterday- putting some engine oil in a bubble, and experimenting with the effect of soap on bubbles, also seeing if leaving bubble mixture from overnight (Natasha) would make better bubbles, the next day.
Bubble play- making a huge bubble that people could stand inside - bubbles inside bubbles, and catching bubbles.

Bubble Week Activities

Seeing if bubbles last longer on a wet surface

Bubble week questions?????

•Can you make different shaped bubbles? (does the shape of the container or the blower make a difference?- Emily)
•Why do they form? (Ms Spyropoulos)
•What do they stick best to? (is water a good thing- Louis?)
•What would happen to a bubble in a vacuum? (Toby)
•Can you make coloured bubbles? (Ms Spyropoulos)
•Can you make stronger bubbles? Does the mixture make a difference? Cameron, Georgia, Natasha, Poppy, Olivia) Harriet thought maybe if you added more washing up liquid to your mixture you would get stronger bubbles.
•What does soap do to bubbles? (Harriet/ Hero)
•Does the size of the blower affect the size of the bubble? (Alfie)
•Can you put something inside a bubble without bursting it? (Eva)

Bubble Experiments

•Do Bubbles last longer on wet surfaces?
•To find this out we compared blowing bubbles onto dry paper and damp paper, and watched to see which bubbles lasted longest. Also we experimented blowing bubbles onto wet and dry patches of playground.
•Result The bubbles lasted up to 49 seconds on wet patches of playground, but burst instantly when they touched dry surfaces.
•Conclusion Bubbles last longest on wet surfaces.

Bubble Week Diary

Monday 24th May
•Literacy- we turned speech bubbles in comics into dialogue following the 'rules of speech marks'. We worked in Literacy books using old Beezer comics, and then marked each others work using our success criterion:
•Blue tick for each sentence using speech marks at the beginning and end of speech.
•Red tick for putting full stop or exclamation/ question mark before closing speech mark.
•Green tick for remembering to begin a new line when a new person begins to speak.
•After Break- we talked about possible bubble activities and bubble questions. (see Bubble question sheet page 1) and discussed how to find out some of the answers to our bubble questions.
Afternoon-
•we devised own bubble experiments to answer our bubble questions. (See photos)
•Just before home-time, we wrote up our experiments, and discussed what we had learnt.

Tuesday 25th May

We spent a few minutes discussing with our 'bubble partners' how to blow a 'perfect bubble'. Then we discussed as a class what advice to give.
We decided that
The Perfect Bubble was...
Strong and big. Wet, light, coloured, perfectly round, (medium- sized), and smells nice!
How to make one
Strengthen the ratio of glycerin, and washing up liquid, blow gently and slowly, do a twist at the end before you release the bubble.)
Then we wondered whether you can make even stronger bubbles if you measure even more washing up liquid or glycerin into the mixture? How much do you need to make the 'perfect bubble'? We experimented measuring different amounts of glycerin, washing- up liquid and water into the mixture, and then blowing bubbles with each solution; to find the 'best one Everyone had a go, blowing a 'perfect' bubble, and we had a competition to see who's was the biggest and who's lasted longest. Jenni won the biggest 9.3cm, and Olivia's lasted the longest- over 8mins. Subjects covered-Maths- measuring and capacity- chn. revised measuring liquids, converting seconds into minutes and measuring using rulers, problem solving (how to measure a bubble?).Science- fair tests, question asking skills, recording.

Perfect Bubble Solution.

We wondered whether we could make the perfect bubble solution to produce the 'perfect' bubble. So we tested some different ratios of mixture to find out which made the 'best' bubbles.
What quantity of bubble ingredients do you need to make the perfect bubble solution?
First we mixed up 5 different kinds of bubble solution to test. Each solution had 20ml of water in. They were as follows.
a) 20ml water, 5ml washing up liquid, 1 teaspoon glycerin.
b) 20ml water, 10ml washing up liquid, 1 teaspoon glycerin. (More wasing up liquid.).
c) 20ml water, 5ml washing up liquid, 2 teaspoon glycerin. (More glycerin).
d) 20ml water, 10ml washing up liquid, 1 teaspoon glycerin. (More wasing up liquid and glycerin).
e) 20ml water, 5ml washing up liquid, 1 teaspoon glycerin. and 1 teaspoon sugar. (Sugar)
f) 20ml water, 10ml washing up liquid, 2 teaspoons glycerin. and 1 teaspoon sugar.(More washing up liquid and glycerin and some sugar).

Results

•The biggest and longest- lasting bubbles were produced using bubble mixture f (More washing-up liquid and glycerin and some sugar). These bubbles lasted over 4 mins. and were also bigger.

Conclusion
•A larger ratio of glycerin, and washing up liquid to water makes more effective bubble mixture but if you add a little bit of sugar it is better still!

This week was Bubble Week, and we have been extremely busy!!!
