Wales Rally GB

We do love a good public event! We especially love the GB rally, which we have attended for the last 3 years. This year’s event was in Llandudno in Wales.

Wales Rally GB is a stage rally motor sport event and, in 2019, was the 12th round of the World Rally Championship. The event takes place over four days of competition and each day is divided into a number of ‘Special Stages’ which are when the drivers race against the clock for the fastest time. For the rest of the event they have to follow a pre-set schedule on normal public roads to get them to the next check point on time.

Branded as Wales Rally GB since 2003 when the Welsh Government became the principal funding partner, the rally is based out of a central Rally Village with competitive stages throughout north and mid Wales.

Wales Rally GB is organised and promoted by Motorsport UK.

We were invited to provide science entertainment for the school days on Thursday and Friday and also for the general public on the Friday night and Saturday. We were straight into the school days as soon as we arrived and we were incredibly busy making slime and encouraging the children to take part in our dry ice experiments. Slime is always extremely popular and it wasn’t long before we had a queue of around 40 children waiting to make their own slime. Even though it was pretty hectic we made sure we were explaining the science of slime making, so the children are learning, whilst having lots of fun!

Dry ice experiments are also always really popular as we encourage the children to add the dry ice into hot water and universal indicator and tell us what they discover. Dry ice experiments always look impressive! Especially when we add bubbles!

We always have a blast at public events but it’s always incredibly hard work! Seeing the children’s excited faces makes it worthwhile though!

Have a great weekend!

The Science of Bath Bombs!

Everyone loves a good bath bomb!  They’re fizzy, colourful and make your bath feel extra special! But did you know there’s some cool science going on as you drop that ball of fizz into your bath? This week we’ve been delivering our bath bomb workshop in Hull, Beverley and Scunthorpe.

Making bath bombs is all about acids and alkalines. Our workshops are aimed at ages 5+ so this is quite a complex topic for the young children but we demonstrate how we can identify acids and alkalis, using substances they recognise and they’re always fascinated.

The acid and alkali combination is what makes that fantastic fizz as you drop the bath bomb into the water. The acid we use is citric acid and our alkaline is sodium bicarbonate. The combination of these 2 ingredients added to water causes a chemical reaction, and gives us that fizz!

But what is citric acid? It’s a relatively weak acid that comes from citrus fruits; lemons, limes and oranges. It’s also added to the outside of fizzy sweets to give them that slightly sour, taste!

Sodium bicarbonate, otherwise known as baking powder is a weak alkaline. If these ingredients are mixed together and then added to water a chemical reaction occurs. The acid and alkaline neutralize the effects of each other. A process called neutralization! Carbon dioxide is formed and this creates rapidly forming bubbles, which is where that fizz comes from! Before the children make the bath bombs we demonstrate this by adding the ingredients to a balloon and watching the carbon dioxide inflate the balloon.

During our workshop the children make 2 bath bombs with a choice of colours and fragrances! The most popular fragrance this week has to be bubblegum! They actually look forward to going home and having a bath!

Thanks to everyone who attended our workshops this week! Next week we have a mixture of volcanoes and slime workshops! See you there!

Holiday time!!

Our summer holiday workshops are now in full swing! This week we’ve been delivering workshops on volcanoes in Hull and Dry Ice in Beverley. We aim to make our science workshops fun and fully hands-on as we believe children learn better through  play and interactivity. 

The volcanoes workshop is great fun and involves a bit of creativity. We start by finding out what children know about volcanoes and then we discuss the different types of volcanoes on Earth and on other planets and moons. Children are always amazed at the idea of cryovolanoes! They then get to build and design their own volcano! We love the fact that parents always get involved! It sometimes gets very competitive! 

Then it’s time to erupt the volcanoes! We use dry ice and hot water to erupt ours. It looks great and has the added bonus of creating a rumble effect, like an earthquake! We then add in a bit of washing up liquid to create bubble lava, which always gets a big “WOAH”!!

This workshop is also popular in schools when children are studying volcanoes as a topic. More details on our website www.labrascals.co.uk

Today we’ve been at the Parks Children’s centre in Hull providing science fun at a family fun day! We made UV bracelets, slime and provided dry ice experiments. We were incredibly busy with slime being extremely popular as usual.

On Friday we’ll be in Flemingate, Beverley with our dry ice workshop. This is really a lesson on the states of matter, but the children have so much fun with the hands-on experiments they don’t realise they’re learning a fairly complex topic. We have a number of experiments that the children complete themselves after a health and safety briefing. There are always lots of “WOW”moments. 

We’ve got lots more holiday workshops to come over the next couple of weeks in Hull, Beverley and Scunthorpe, including bath bombs, slime, volcanoes and planetarium! Book now to avoid disappointment!

Space Volcanoes!

We’ve been delivering some workshop for Public Libraries in Hull over the summer, on volcanoes of the solar system, in keeping with their reading scheme space theme. But how different can volcanoes actually be? The answer is, very! But the mechanism causing them to erupt is basically the same. It’s all about pressure building under the surface. That pressure has to balance and release somewhere. That’s when a volcanic eruption occurs.

Active volcanoes are those which are currently erupting or have erupted in human history. We mainly use this term in regards to volcanoes on Earth, but the most active place in our solar system is one of Jupiter’s moons. Io is the innermost of Jupiter’s moons and is a little larger than our moon, with a radius of 1,131 miles. It has over 400 active volcanoes on its surface, produced by the gravitational pull of Jupiter creating tidal heating inside Io. This means that Io is being pushed and pulled by Jupiter, which causes friction deep inside the moon and creates this volcanic activity. Although Io has an icy surface, lava erupts hundreds of miles above the surface due to this tidal heating and low gravity.

Back to volcanoes on Earth. They erupt lava. They can occur on the surface of the Earth and also under the sea. Imagine that the Earth’s crust is a bit like a cracked eggshell. The pieces of the eggshell are the tectonic plates. Hotspots sometimes occur in the middle of the Earth’s tectonic plates and cause eruptions on the seabed with the lava cooling to rock. The hotspot itself is fixed but the plates move, sometimes creating a series of islands, like Hawaii!

Further out in the solar system where temperatures are extremely cold, a different kind of volcano occurs. Ice volcanoes. In the far reaches of the solar system on Pluto, where the temperatures are around -200 degrees C, ice volcanoes exist. Otherwise known as cryovolcanoes these icy giants tower around 3500 m above the surface of Pluto.

Although we have no observations of cryovolcanoes erupting on Pluto, there is evidence to suggest that it could possibly be geologically active. So how do volcanoes erupt ice? Well, we’re not 100% sure but imagine geological activity inside bodies like Pluto have warmed the frozen surface into a Slush Puppy! The moving ice sheets grind together inside and expel this above the surface as a cryovolcano! Unfortunately our observations of Pluto were very brief as the New Horizons spacecraft whizzed by in 2015, so we didn’t actually see any eruptions! We saw the very first cryovolcano on Neptune’s moon Triton as Voyager 2 flew by in 1989.

So Earth isn’t the only body of our solar system with volcanoes! We’ve also seen evidence of past volcanism on Mars, Venus and our very own moon! And the children in our workshops love learning about the different volcano types and designing their own!


If you haven’t managed to book onto the library sessions then we have spaces available on our own workshops (including volcanoes) in Hull, Scunthorpe and Beverley. Book online now!

Apollo 50

Tomorrow is the 50th anniversary of the first moon landing.

On July 20th, 1969 at 2117 UK time, Neil Armstrong and Buzz Aldrin landed on the moon, making them the first humans to ever land on another world. The world watched as Armstrong took his first step onto the moon and Aldrin followed, while Michael Collins flew the command and service modules in orbit around the moon.

This momentous event was the culmination of over a decade of hard work by over 400,000 people. 530 million people watched around the world.

But this was 50 years ago! Not everyone can remember the moon landings themselves and a lot of the children we work with, don’t even know that they happened. So our Astronomy manager created a planetarium show to commemorate the anniversary of the moon landings. We’ve had a busy week taking the show into schools, including Stepney Primary, where the whole school watched the show. This show was designed for KS2 and older children but we managed to adapt it so the children in the nursery and reception could enjoy it too. It was hugely successful! Over 180 children experiencing the moon landing in 1 day!

Tomorrow, on the day of the anniversary, we will be helping Hull Libraries to launch their reading scheme. This year the scheme has a space theme and we will be performing our show all day! We’re honoured to be able to perform these sold-out shows to a public audience on such an important day! See you there?

Have a great weekend! Keep looking up!

Chile adventure!

We’ve had a busy few weeks doing lots of planning! The summer holidays are creeping up fast and we have lots of exciting workshops planned, including public showings of our new planetarium show “One Giant Leap”. Details of workshops are here https://bookwhen.com/labrascals#focus=ev-sbaw-20190807100000

Our Astronomy Manager, Cosmic Carol is getting ready to jet off to the Atacama Desert in Chile next week after winning a place on the European Southern Observatory social media team for the total solar eclipse. She’ll spend 7 days in the Atacama Desert, visiting various observatories and posting about it on social media. You can follow her on Twitter @Cosmic_Carol

She’ll be watching the solar eclipse on 2nd July from La Silla. The La Silla Observatory is located on the outskirts of the Chilean Atacama Desert, 600 km north of Santiago de Chile and at an altitude of 2400 metres. Like other observatories in this geographical area, La Silla is located far from sources of light pollution and, like the Paranal Observatory, home to the Very Large Telescope, it has one of the darkest night skies on the Earth. La Silla has been an ESO stronghold since the 1960s. Here, ESO operates two of the most productive 4-metre class telescopes in the world.

She will also visit the VLT (very large telescope) based at the Paranal Observatory, famous for being blown up in Quantum of Solace.

https://www.hq.eso.org/public/teles-instr/paranal-observatory/vlt/

And will also visit ALMA . A state-of-the-art telescope to study light with wavelengths of about one millimetre, shining from some of the coldest objects in the Universe, ALMA is a cooperation of the European Southern Observatory (ESO), together with its international partners. The site of ALMA is the 5000-m altitude Chajnantor plateau in northern Chile, one of the driest places on Earth.

If you’re a teacher and you’d like Carol to come into school and talk about her experiences in Chile, send us and email on labrascals1@gmail.com.

Have a great weekend!

Half Term Science Fun

It’s been half term for most schools in East Yorkshire and North East Lincolnshire this week! But there’s no rest for us! We’ve been out and about delivering science workshops!

On Wednesday we were based at Burnby Halls and Gardens for their Community Day. After the terrible weather at the beginning of the week we were happy to see the sun shining!

Burnby Hall belonged to Percy and Katherine Stewart. Between 1906 and 1926, Percy and Katharine completed eight world tours, covering North America and Canada, Africa, India and the Far East, Europe, New Zealand, and the Pacific Islands with Percy using his trips to hunt, shoot and fish. He and Katharine brought back souvenirs and trophies which now form the Stewart Museum collection. These are an eclectic mix of statuary, hunting trophies and curiosities.

Katharine died in April 1939 and Percy remained at Burnby Hall for the remainder of his life. He lived until the grand old age of 90, assisted in later life by his faithful housekeeper Miss Tibbott.

Both he and Katharine had no children and decided to leave the estate in trust to the people of Pocklington when they died.

On his death in 1962, these wishes were complied with and the Stewart Trust, established in 1964 was set up to run Burnby Hall Gardens and to administer the Stewart Museum collection.

The gardens feature 2 lakes which hold a national collection of Waterlilies

So it was a stunning location for delivering our slime workshops! We delivered 2 workshops throughout the day, both being fully booked really early in the day! The children made 2 different kinds of slime and learnt the science behind the slime. Everyone had a great time and we had some lovely feedback from the parents.

On Thursday we travelled to Scunthorpe to the Engineering University Technical College, where they hosted a Primary Lego STEM event, for Year 5 pupils. We delivered our LEGO wind energy workshop to a really enthusiastic group of children! They had excellent LEGO building skills and worked really well together in teams.

This was a really successful workshop. All the children really enjoyed it! And so did we!

We’ve spent the rest of the week working on a new Astronomy course we’re putting together, to be delivered in our planetarium. Watch this space!! (see what I did there?)

Have a great weekend!
