Good morning Primary 7,
It’s Thursday which means it’s time to get our imaginations flowing and do some creative writing. Today I would like you to use the picture below to write an interesting story. Remember to take care with your use of punctuation and try to challenge yourself by using some amazing descriptive vocabulary.
How did you discover this new planet? What is it like? Does anyone live on this planet?
I would love to read your amazing stories, feel free to email them to me:

I know how much you all love playing the Countdown number challenge in class so why not go on to the website below and see if you can reach your target number using the four number operations.

I hope you all had a chance to either watch or carry out yesterday’s science experiment. Who made an accurate hypothesis (predicted what would happen) and now understands why the diet can floated and the regular can sank?
If you aren’t too sure how the experiment worked here is an explanation:
How Does the Experiment Work?
The simple answer is that the density of the cans causes them to either float or sink. The cans of diet juice are less dense than water, so they float. The cans of regular juice are more dense than water so they sink.
Now you may be wondering why the density of the cans is different. The answer, is the type of sweetener used in each can.
- Sugar is used to sweeten regular cans of juice, a lot of sugar. This large quantity of sugar causes the can to become more dense than water.
- Artificial sweeteners are used in diet juice. However, a smaller amount of artificial sweetener is used which causes the can to be less dense than water.
So there you have it, even though the cans were the exact same shape, size and volume (330 ml) the densities were different.
Have a terrific Thursday everyone and I look forward to reading some of your exciting stories. Remember to complete day 2 of your April maths calendar.
Mrs Butler 🙂
