June is bustin’ out all over!! Wah! Wah! Oh the oldies are always the goodies. Where’s flaming June then?  More like freezin’ June. So much for the sun cream, bring out the handwarmers again. What is going on? Never mind, Planet Science is here to warm you up with a medley of science snippets and jolly japes that will have you smiling through your blue lips.

The line-up this week:

  1. Mint Nuggets – how are our mintally-challenged growers getting on?
  2. Activity of the Week: Bad Breath
  3. Mouses at the Ready: Centre of the Cell Trumps
  4. Noticeboard: FYI
  5. Recommended websites of the week
  6. The Winners’ Enclosure
  7. Joke of the Week

Did you get one of our Making a Mint packs? No? How sad.  Unfortunately all the packs have now gone.  Yes all 5000 of them! Who-hoo! There must be a serious amount of mint being grown out there now.  Anyway we thought you might like to hear what some of you are up to …

Sue Welch of Easton Royal School tells us

“Thought you might like to know about a Produce Challenge I have set my class.  The challenge was inspired by the Making a Mint challenge.  I teach in a small rural village school that only has 2 classes.  I teach all the children in KS2.  As we were studying plant growth this term as part of Science I thought I would approach it from a different angle to the usual angle of looking at Bean growth etc. 

The children have been put into groups of 4 and have been given a small amount of seeds, some seedlings, I had grown, and a budget of £10 that our PTA have loaned them.  They have been challenged to grow as many plants that they can to either sell on or sell produce from.  We are going to have a plant sale near the end of term and invite parents, friends and local villagers to come and buy.

The challenge has really got the children buzzing.  We started it off on the first day of term by planting the seeds I had given them and then I demonstrated how to prick out seedlings and re-pot larger plants.  They then had a go at this.  They were then given some time to come up with a company name and do some research on vegetables, fruits and flowering plants that they might like to grow. 

On the Friday we visited the local garden centre to purchase seeds or small plants - all the decisions were made by the group. Last week we had a mass planting session and the library and the classroom now look like a giant nursery - with plants and seed trays every where.

The aim of the project, apart from teaching the children the science behind plant growth, is to get them inspired about growing their own produce, to get them to think more carefully about what they eat and where it comes from, to teach them how to budget with money and to think about recycling - (as well as using actual pots we are experimenting with plastic packaging, juice cartons, cardboard tubes etc) and of course composting.  It also ties in nicely with our Healthy Schools' Programme.

We have of course planted the Mint seeds that you sent us - so we hope to be able to sell that too.  One group have named themselves Happy Herbs and are going into herb production - inspired by the free mint seeds.

I will let you know how the children get on.”

Please do, Sue! And if anyone else has any news to share on the weird and wonderful way they are using their mint then please send us an email with the words MINT NUGGETS in the subject line, to planet-science.news@nesta.org.uk.

2. Activity of the Week: Bad Breath

Surely not. Something even your best friend won’t tell you? Actually your breath isn’t ‘bad’ as such.  But the mixture of gases we breathe out is very different to the air we breathe in. Our bodies need oxygen to live and we get that from the air that we breathe. The process of respiration converts the oxygen to CO2. So the mixture we breathe out has more carbon dioxide (CO2) than the air we breathe in.

Note: adult supervision is required throughout this activity.

You will need:

  • A small candle (like a tealight) and matches
  • Vinegar
  • Hot water (from the hot tap)
  • Bicarbonate of soda
  • A jug with a lip that you can pour from
  • Another container to mix the water and vinegar

What to do:

  1. In your container, prepare a hot water and vinegar mix, (50-50 of each).
  2. Light the candle. (This should be done by an adult)
  3. Put about a dessertspoon of baking powder in your jug, then pour on the vinegar-water mix.
  4. Let the fizz subside for a second or so, then take the jug and carefully ‘pour’ the CO2 over the candle. It will go out, ‘suffocated’ by the lack of oxygen.

What’s going on?

CO2 is heavier than air so when you lean the jug over the candle CO2 falls out and sinks onto the flame extinguishing it.

Where CO2 issues out of the ground in high concentrations it stays close to the ground. In sheltered areas it has killed birds, mice and cats. In Cameroon, there was a sudden efflux of CO2 that had collected under a lake – the gas flooded a village and all the people were killed.

This experiment came from the Little Book of Experiments.

3. Mouses at the Ready

Centre of the Cell online is packed with facts, pictures, games and films inspired by the ongoing work of more than 60 leading scientists and doctors at Queen Mary, University of London and its Medical School (QMUL). What’s more there will be an interactive centre to visit from Spring 2008. The Centre of the Cell team has converted one of the exhibition's digital interactives into a unique, educational and entertaining card game.  Behold Cell Trumps! What’s more, they have given us THREE sets to give away.  All you have to do is answer the following question:

How many cells do you have in your body?

  1. Around 50 – 100 cells
  2. Around 50 – 100 million cells
  3. Around 50 – 100 million million cells

The answer can be found on the website. http://www.centreofthecell.org/

So if you want to win one, send an email with the answer together with your name and address, and the words CELL TRUMPS in the subject line, to planet-science.news@nesta.org.uk.

The draw will take place at 5pm on Wednesday 6th June.

The June Exam Quiz

For all you poor examinees this month – we want you to know we feel your pain. So in a salute to you in your month of suffering we’ve, er…oh hang on…um…not sure this works... made a quiz in your honour. Oh well, you should have such a head full of knowledge this will be a piece of cake.

Your prizes are things that may help if you find yourself undergoing the revision process again in the future… USB plug-in coffee warmer/keyboard vacuume cleaner and shoulder massager kit and retro flip date clock for that authentic deadline feeling!

 


5. Recommended websites of the week

Whoop! Whoop! our sonar device tells us that there’s a great website out there and here’s Lis Maclaren of DEEPSEAS Group at the National Oceanography Centre, Southampton to tell us all about it.

“The website is http://archive.serpentproject.com/. It is a database of really cool photos and videos of deep-sea animals in their natural habitat in the deep-ocean. The project I work on, based at the National Oceanography Centre in Southampton, collaborates with the oil and gas industry – we use their ROVs (Remotely Operated Vehicles) to carry out deep-sea research and document biodiversity. One aspect of this collaboration is that we have a whole host of footage and images from the deep sea. We have been working hard to go through all these images over the years and have identified a lot of the species – but we still have a few to go! There are over 1000 records in there so far and we have probably another 300 that we will aim to get up over the next few months, and more keep rolling in!”

So there you have it – if you want to have a gander at a Venus Flytrap Anemone (from the Ivory Coast) then you know where to go.  Small question though … how many flies are there at the bottom of the ocean?

If you have any Recommended Websites of the Week then please let us know by sending them in an email with the words RWW in the subject line, to planet-science.news@nesta.org.uk. After all, if nobody tells us about them then they’re not ‘recommended’ are they?

7. Joke of the week

A woman was out golfing one day when she hit her ball into the woods. She went into the woods to look for it and found a frog in a trap. The frog said to her, "If you release me from this trap, I will grant you 3 wishes."

The woman freed the frog.

The frog said, "Thank you, but I failed to mention that there was a condition to your wishes that whatever you wish for, your husband will get 10 times more or better!"

The woman said, "That would be okay."

For her first wish, she wanted to be the most beautiful woman in the world.

The frog warned her, "You do realize that this wish will also make your husband the most handsome man in the world, an Adonis, that women will flock to."

The woman replied, "That will be okay because I will be the most beautiful woman and he will only have eyes for me." So, KAZAM she's the most beautiful woman in the world!

For her second wish, she wanted to be the richest woman in the world. The frog said, "That will make your husband the richest man in the world and he will be ten times richer than you."

The woman said, "That will be okay because what's mine is his and what's his is mine."

So, KAZAM she's the richest woman in the world!

The frog then inquired about her third wish, and she answered. "I'd like a mild heart attack."
