The committee came up with the idea for a new lunchtime club, which we are calling the Scientific Fun Club. The reason why we started this club is so that children can learn more science in a fun way. We would like to hear if you have any ideas for a final name for the club. Here are some pictures of what happened in the club so you can see what we did.
First of all we checked who wanted to come in each class. There were too many people who wanted to come so we invited a different class every week. This week it was a success. We had 23 children from Y1 and also some Y6s and committee members who helped out. Children could choose what to do from drawing, making Lottie doll accessories, playing games and reading books. The main rule was to have fun.

Having conquered the technique of the ‘marble run’, using a large cardboard tube and ping pong balls, Joshua is now developing ways of creating the required incline of the tube by leaning it against tables so that he can look inside the tube and watch the balls roll down.
Adrian worked carefully and methodically to make three musical instruments during the Lab_13’s study of sound. When Betti, Rosehill’s Scientist In Residence, told him he could take them home, his whole face lit up!
During an activity where pupils were playing with ping pong balls on steel drums, Elizabeth found a cup from another activity, filled it with the ball and then developed her own system of ‘pouring’ the balls onto the drum.
This morning the Lab_13 committee decided to act on the contents of a confidential letter (it was a piece of paper that we wrote on last week), which held the plans for the next term. Now we can unveil the hidden plans for next term, written by us, the committee.
We are delighted to announce that we will be screening a film called Hidden Figures in Lab_13. We really want children to be inspired by this story about equality for men and women and all people fighting against prejudice.
One other thing that is important this year: our summer fair will be more sciencey than ever before. There will be a competition (tbc) as well.

Tuesday 14th March
For a long time we have been planning our Lab-13 Lectures, and tomorrow is the day! We are going to present our lectures about Sound to about 400 children and teachers! Jamie says that he is scared, but James is just excited. We have planned our talks in partners: Elizabeth and Izzy about how sound is made by vibrations, James and Ellie about how sound travels in waves, Ty and Sam have some experiments about how we hear sound, and finally Jamie and Charlotte have some great facts and recordings about how bats and dolphins use ultrasound. We’re about to go and practice at Wollaston: it’s really exciting!
Wednesday 15th March
The day has arrived we are all scared and nervous but hopefully it will go well! We meet in the morning at school at 8:15am, so that we have plenty of time to get ready for the lectures.
When we got to Wollaston School we went to the hall that was very big with comfy seats. We had some spare time to practise, when we practised there was just one thing that we all were doing wrong: we were all talking too fast so we ALL NEEDED TO SLOW DOWN! We also got to practice with real volunteers for the first time: which was good because we discovered that volunteers are very bad at doing what you want!
During the actual show, it all went really well! The audience really enjoyed being part of a sound wave, and testing their own hearing. After we did all our own lectures, the fantastic Rick Hall presented a quiz where the audience had to decide if new inventions were real, or made up. Everyone in the audience got to vote by holding up wither a green (for fact) or red (for fiction) card. Finally Mr Sheldrick and Mr Bodycote (science teachers from Wollaston School) did some experiments. Not just any experiments though: They were trying to impress us to decide if chemistry or Physics was the best!
Afterwards we had some time to experiment with our new giant slinky, and Rick showed us some more experiments he had brought with him. We also caught a few passing teachers and showed them all of our experiments! The day went very well, and when we got back to school everyone was tired. Elizabeth would love to do the lectures again though: maybe we will do them for the rest of our school!
As we said in our previous blog, we put on our annual Science Spectacular last week. This is to share what we have been doing so that children and adults are inspired to be curious and do science. The Science Spectacular is a show about science and engineering featuring experts in science and technology for example Sheila and Andres who were part of our Science Spectacular this year.
Before the show started we organised three tables to showcase science and engineering projects that we have taken part in this year:
Kiri and Reiss introduced the show by asking the question: is the Moon made out of cheese? They also explained that the Moon is about a quarter of the width of the Earth. They showed us this apple, saying that if the Earth were this size then the Moon would be the size of this cherry tomato, and they would be about 2m apart.
Daniel and Hamza came to the stage to help us learn how to get to the Moon. We invited Andres to help us because he is a technician who knows about rockets. He helped us to investigate pipette rockets and we tried to launch them and hit a drawing of the Moon. It was very fun as we first tried just hydrogen and tried to hit the Moon but it didn’t work. Then we tried oxygen and that still didn’t work. So then we thought mixing them together might work. We tried it and it worked! This was a combustion reactions, where oxygen and fuel (hydrogen) react to make water. But we needed the pipette rocket to get to the Moon and it only got half way. So next we added water (a propellant), hydrogen and oxygen and that was better but it still didn’t hit the moon. Finally we tried air, hydrogen, oxygen and water. It hit the Moon! Yay!
The next guest was Dr Sheila Kanani and she was introduced by Nimo and Choi ying, who also told some very funny jokes (funny and cheesy!). She showed us how to make a home-made comet and it was very engaging and funny. We learnt many things, we were most surprised that some comets have the ingredients for life in them. We were also surprised that dry ice is colder than the North Pole, but it also burns you.
As for our big finale we wanted to see once and for all whether the Moon was really made of cheese. So we decided we needed a piece of Moon to examine so that we could find out. First we examined pieces of cheese under the microscope and then our big reveal: NASA had lent us a piece of Moon! Carole had been carrying it in her bag all along. We were over the Moon to have real pieces of Moon in our school, and we couldn’t wait to examine them. Our final conclusion that the Moon is not made of cheese, sadly.
We found out in the Science Spectacular that science isn’t just about the scientists, but the technicians who work with them are also really important. Two members of the committee were our light and media technicians on the night and they did a brilliant job.
We all had a wonderful time, and the feedback we have received from guests has been so positive. Thank you to everyone who came and who helped us out!

Between November and January, all the pupils at Rosehill had the opportunity to engage in activities in the Lab_13 and develop their curiosity. Those who were particularly engaged were chosen by teachers to continue working on developing their interest in scientific inquiry. During the January-February half term, these pupils continued to build on their knowledge of light and dark to learn about Earth and space in the January-February half term.
Pupils have been exploring objects on a light box, looking at different colours using the OHP, exploring torches and UV objects and looking at paint under different lights.
On Tuesday 28th February and the 1st of March at parent evening, Lab_ 13 ran a little stall doing experiments to do with taste: we were inspired by the BBC Terrific Scientific supertasters experiment.
For the first experiment we showed pupils and parents 3 different colour drinks: red, orange and green. We asked them to taste all 3 and write down what flavour they thought each drink was. We got 38 people to try this experiment!
For the red drink, 37% thought it was a red fruit flavour, 10 people said strawberry. For the orange drink, 47% thought it was an orange fruit flavour, 15 people said orange. For the green drink, 58% thought it was a green fruit flavour, 11 people said apple and 12 people said lime.
The interesting bit is that we managed to trick almost everyone! All three drinks were actually lemonade! Our experiment was to see if what people tasted would depend on the colour. Our experiment has shown that colour does have an big effect: about half of the people thought each drink was a flavour that matched the colour, and only 5 people though all three drinks tasted exactly the same, and none of them said it tasted of lemonade!
We found out that the green drink seemed to trick the most people, but maybe that is because lemon flavour is quite close to lime flavour.
We also tried the experiment with summer fruits flavour instead of lemonade, but this did not work as well. This is probably because the real flavour was stronger than for lemonade, so it was harder for people to imagine the colour flavour.
The other experiment we did used blue food dye colour to see if you are a taster, non-taster or super taster. Firstly, we asked the grownups and the children taking part if they wanted us to paint their tongue blue, or to do it themselves. Then they had to wait 1 minute with their blue tongue sticking out. This was a bit funny, because some people dribbled and they had silly expressions on their faces. Also, it was their only chance to stick their tongues out at people without being rude!
After 1 minute, we counted how many pink taste buds were on their tongue inside the space of a hole punched in a piece of card. If it is between 0 and 5 you are a non-taster, if it is between 6 and 10 you are a taster and if you have 11+ then you are a super-taster. Of the adults and children we tested, 25% were non tasters, 42% were tasters, and 33% were supertasters. The fewest taste buds someone had was 2, and the most was 21! Supertasters should be able to taste bitter things more strongly, so are less likely to like bitter things like Brussel sprouts and coffee.

Hello and welcome to the Lab_13 Blog!!!
Today’s blog is about… the Lab_13 Irchester Half Term Holiday Club! All the children who came to the club had LOTS OF FUN!!! They made rocket fuel (for POP ROCKETS not REAL ROCKETS) by experimenting to see which mixture of chemicals would react the best by making lots of fizz and bubbles. They also used the lab’s giant air-zooka and made their own mini air-zookas to take home, after using them to knock down their huge cup towers!
We will tell you how to make pop rocket fuel and mini air-zookas, so you can do it yourself too!
For the rocket fuel, we used three liquids: vinegar, water and laundry liquid, and three solids: citric acid (powder), Bicarbonate of Soda (also a powder) and fizzy vitamin tablets (a tablet).
The best combination for us was…………
LAUNDRY LIQUID and CITRIC ACID!!!
The reason they were the winners was because they fizzed (reacted) the most, and the fizzing shows that the reaction is making a gas, which is what makes the rocket launch! They reacted because the citric acid is an acid, and the laundry liquid is an alkali.
To make a pop rocket you will need:
To make your rocket ready to launch:
The rockets made a big mess in the playground, but luckily the rain washed it all away. Science club loved seeing how high the rockets went, much higher than they expected!
The air-zooka works by pushing all the air inside the container out of the hole, whenever you ping the sheet at the back. It makes a ball (or vortex) of moving air that you can feel hit you even at the other end of the room!
The mini air-zookas work just the same, except they are much smaller. You could still knock down cups towers with them though!
How to make mini air-zookas you will need:
Everyone at holiday club really enjoyed the day. Finlay’s favourite part was launching the rockets, while Miss Draper enjoyed shooting everyone with the air-zooka!

The Lab_13 at Rosehill had a visit in January from scientists from the School of Physics and Astronomy at the University of Nottingham.
They brought along an inflatable planetarium, known as an inflativerse! You can read more information about the Inflativerse here: http://www.nottingham.ac.uk/astronomy/planetarium/Home.html
The children had a great time exploring the inflativerse and really enjoyed the visit from scientists.
On the 14th March we are hosting a Science Spectacular at Gillespie. There will be a handful of special guests helping us to answer a question about space. It begins at 5.30pm, when you can come to explore what we’ve been doing lately in the lab and hold special mystery objects.
The show starts at 6pm, when everybody settles down to enjoy and listen to our spectacular science performance. It will be humorous, there will be cheesy jokes, inventions, rockets, investigations and comets. Expect it to be a VIP (Very Important Performance… or a VVIP, a Very Very Important Performance).
We don’t want to say too much because you will just be sitting at home reading this blog, and instead you should come and enjoy the show. If you can’t make it, look out for our next blog. There will be lots of information and pictures. It will be just like you were there (but not literally).
