As many of you know, I often listen to the radio as I’m getting things set up in the classroom each morning – it’s usually Radio 2. Whilst I’ve not been in school so much, I’ve really enjoyed listening to the radio and I heard a fantastic challenge on Zoe Ball’s Breakfast Show, which I’d like to share with you.
Can you write a story that has just 26 words in it, with each word starting with the letters of the alphabet in order?
Here’s one I heard…
A beautiful, courageous duckling excitedly flew great heights into Jack’s kingdoms. “Look! Make note!” observed people. Quickly rising, she travelled upwards valiantly, wings xanthic, yielding zigzags.
Can you write one? Or can you write one that is 26 sentences long, with each sentence starting with a word that is in alphabetical order? For example, it might start like this… Amy couldn’t believe her eyes! Beneath her, lying on the sand was a pebble. Cautiously, she bent down to pick it up.

I can’t wait to see it!
This week I've got an online game for you to play, which is all about using related number facts. Remember, the inverse of addition is subtraction... and the inverse of multiplication is division.
7 x 9 = 63 9 x 7 = 63 63 ÷ 9 = 7 63 ÷ 7 = 9
17 + 33 = 50 33 + 17 = 50 50 - 33 = 17 50 - 17 = 33
When you follow the link, first choose whether you want to do addition and subtraction, or multiplication and division. Then decide on the level of challenge that you want to try. After that, just follow the instructions on the screen...
I’ve got a question for you this week… Can you make an egg bounce?
Well, if you dropped a raw egg to the floor, we all know what is going to happen!
But, if you follow these simple steps, you CAN make an egg bounce.
What you will need:
• I raw egg
• White vinegar
• A bowl
• Kitchen roll
• Food colouring – if you want to take the EXTRA CHALLENGE
• Golden syrup - if you want to take the EXTRA CHALLENGE
What you need to do:
1. Place the egg in a bowl and pour the vinegar in until the egg is fully covered. (You can always place a plate on top of the bowl to ensure it stays submerged in the vinegar).
2. 72 hours later, (or 3 days later), carefully empty the vinegar and gently rinse the egg with tap water so that all the shell is removed. If there are patches of shell, do not scratch them off as it may puncture the egg. Try gently rubbing and rinsing it off. If it won’t come off, place back in the bowl with fresh vinegar and leave for another 24 hours (or 1 day).
3. Dry your egg carefully on a piece of kitchen roll – then you’re ready to start experimenting!
4. Weigh your egg and record its weight.
5. Now drop your egg, from a height of about 20cm, onto a flat surface, and hopefully it will bounce!
6. After you have bounced the egg once, record its weight again.
7. Place the egg in a bowl and completely cover it with golden syrup. Leave this for six hours. When you take it out, the skin is wrinkly and the egg soft. Dry and weigh the egg – hopefully it will be lighter than before!
8. Place the lighter, wrinkled egg into a bowl of water with a few drops of food dye and leave for another 6 hours.
9. After around 6 hours, take the egg out and you should notice the egg is firm again and bouncy. After drying it, weigh it again – it should be heavier again!
If you look closely, you should be able to see that the egg is now the colour of the food dye.
The egg should bounce better than it originally did, but don’t drop it from too great height as it will burst everywhere!
Don’t forget, that science experiments will not always work the first time! You may need to use more than one egg to get it to work. Watch the clip below to see how one experiment worked out…
Don’t forget to send in any photos or videos of your own Bouncing Egg Experiment!
Once you’ve had a go, read the explanation below, the Science-y-bit, as to why it works…
The vinegar is a weak acid. It reacts with the shell, removing it without affecting the egg inside. This is because the egg is surrounded by a strong skin called a membrane which acid does not affect. The membrane allows water to pass through but stops other things. This effect is called ‘osmosis’. This experiment is an example of osmosis through a semi-permeable membrane. So, when you put the egg into the syrup, water passes out of the egg through the membrane and the egg becomes lighter. Alternatively, when you put it into water (with food colouring) the water passes into the egg and it gets heavier.
When you have finished the experiment, why not place the egg into a basin and cut open the membrane! You should find a raw egg with food dye – pretty cool huh?
Did you notice that when the acid of the vinegar reacted with the egg-shell it was an irreversible reaction as you can’t grow the shell back! The shell of the eggs is for protection and the membrane surrounding it protects the growing chick from, among other things, drying out.
Why don’t you now watch the video about the chicks at Hyden Farm, on the Video Resource Centre page?

This week you are going to be in charge of building a pyramid! Take a look at the website below:
You could take a screen shot of your finished pyramid – I’d love to see it!
You could even create a poster all about building a pyramid, or a powerpoint, if you wanted to. Let your creative ideas flow…
Send me in any examples of what you have done to email@example.com
Last week, I set you the challenge of naming the birds in the photos, so the first thing I need to do is reveal the answers.
Take a look at the photos below, which now have their names added in – how many did you get correct?
This week, you need to use your sense of hearing. You can do this at home in your garden, or on your balcony, or even on your daily walk.
Sit back to back with a partner and just listen, carefully, for 3 minutes. Write down all the different sounds you hear. Then, compare your list with your partner. Did you both hear the same things?
Why don't you record what you heard in a creative way?
- You could cut out pictures from magazines, or newspapers, of the things you heard and make them into a poster
- You could hide the names of what you heard in a wordsearch and give it to someone at home to solve
- You could draw your own pictures of what you heard
The choice is yours!...
Keep on sending in your work, photos, pictures, videos… I love to see them and I put them all onto our class page for everyone to see!
I will also reply to anyone that sends in a message, as some of you know already… firstname.lastname@example.org
