Celebrating Science

Science Club create invisible extinguishers!

23.05.22 – Today, Science Club had fun putting out fire by creating their own invisible extinguishers using baking soda and vinegar. We learned that the baking soda/vinegar reaction results in a gas called Carbon Dioxide (CO2). When we poured our cup of CO2 into the glass containing the candle, the CO2 sinks to the bottom of the cup and surrounds the candle. This or pushes up all the normally mixed air, along with all that oxygen the fire needs to burn. 

Year 5 Life Centre visit

18.05.22 – Year 5 had the most amazing day at the life centre! We took part in a ‘Discovering chemistry’ workshop where we took on the role of a chemist and used real laboratory equipment to identify mystery powders and create new substances. We looked at how a flame can be used to identify a chemical and discovered the beauty and wonder of chemical reactions.
We also built our own moon buggies using a range of materials before taking them for a test drive on a recreation of the moon’s bumpy surface.
We were then lucky enough to explore the brain zone, creative zone and the space zone in the life centre before visiting the planetarium.
A fantastic day had by all!

Science club make magical milk art!

17.05.22 – Today, Science club enjoyed making some pretty patterns using milk, food colouring and washing up liquid. Milk has fat in it and the food coloring floats on top of the fat. The fat is all connected with bonds. Dish soaps are used on greasy or oily dishes because it breaks the bonds in fats allowing them to separate. When you add the dish soap to the milk, the fat separates and moves making your magical milk art!

Science club make ice cream!

09.05.22 – Today, Science club had fun making their own ice cream in a bag! Instead of placing the ingredients for ice cream in the freezer, we mixed together salt and ice to make a solution. We learned that adding salt to the ice lowers the temperature at which water freezes.

Science club crazy catapults!

25.04.22 – Today, Science club had fun making catapults using marshmallows and wooden sticks. After making our catapults we investigated:
– What happens if you try to catapult larger marshmallows? Does having a heavier projectile affect the distance?
– Does using a thicker elastic band affect the catapult?
– How will the distance that the projectile travels change if you attach a longer or short skewer to your lever?

We discovered that by catapulting our mini marshmallow into the air, we are demonstrating Newton’s laws of motion. The further back we pull the lever (spoon), the more potential energy is stored in the elastic band until the spoon is released. When we let go of the spoon, this potential energy is released creating a force called kinetic energy (energy in motion).

We then enjoyed having a competition to see which of our catapults allowed the marshmallow to travel the furthest.

Science club Easter fun!

04.04.22 – Today, Science club made colourful marbled Easter eggs using hard boiled eggs, food colouring, oil and vinegar. 

Science club make bath bombs!

28.03.22 – Today, Science club enjoyed making our own bath bombs. We experimented with different colours, shapes, scents and even added

Science club investigate fingerprints!

21.03.22 – Today, Science club acted as detectives and investigated fingerprints. We took our own fingerprints by either rubbing pencil onto a piece of paper or sprinkling a small amount of flour on a table. We then put our thumbs in the flour or pencil rubbing and then placed our thumbs firmly on to the sticky side of a piece of sellotape before sticking the sellotape onto a piece of paper. Using magnifying glasses we looked closely at the different patterns found in fingerprints (loops, arches and whorls) and compared them to our partners. We then shared all the fingerprints and tried to work out which were ours.

British Science Week 2022

At Southwick we have had so much fun celebrating British Science Week. The theme was ‘growth’ and each year group enjoyed exploring ‘growth’ in different ways. Take a look at some of the wonderful work we completed during our 2022 Science Week.


Nursery have loved learning about growing for Science Week. To start with we looked at baby photos of the children and the teachers and talked about how much we have changed and how much we have learned. Then we became plant detectives! We loved exploring outdoors, the children used some excellent vocabulary such as, “leaves”, “petals”, “flowers” and “roots”. We talked about what plants need to grow, then we planted a sunflower seed each and watered them and waited for them to grow.


In Reception we looked at and labelled the different parts of the flower and also learned about the life cycle of a flower. We did observational paintings and drawings of various flowers. We also investigated the inside of different fruits and used our fine motor skills to remove the seeds from within. We did some planting outdoors in our gardening area as well as inside including an experiment where we looked at how plants survive in different conditions. In the tuff tray we explored the roots of the flower and different vegetables and bulbs.

Year 1

Year 1 had some special visitors to see them during Science week. We were lucky enough to have Angela bring some wonderful animals for us to hold and look at. There were geckos, bearded dragons and skinny pigs! We learnt about where they live, what they like to eat in their habitat and how they grow and change into adults. Here are some of the photos from the visit.

Year 2

Year 2 have had lots of fun exploring the conditions needed to grow cress for Mrs Ellison’s favourite sandwiches… egg and cress! We started the week by planning our experiment and talking about how we were going to ensure a fair test. We wrote our aim, prediction, equipment list, how we were going to make sure our investigation was fair and our method. We spoke about what seeds need to grow and the conditions we think would be best to grow cress. We then followed our method to plant our cress seeds. Every day, after lunch, we observed our plant pots to see if any changes occurred. We then filled in our observation table. We kept two cress pots in the cupboard (one with water and one without) and two on the windowsill (one with water and one without) Next week, we will continue to observe out cress seeds and write up our findings. 

With Miss Atkinson, we created a large scale plant out of craft materials and spoke about the different parts of a plant. We also discussed the function/purpose of each part of the plant.

On Thursday morning, we had a great morning with Angela from ‘Angela’s Ark’ we got to hold and learn about lots of different animals. We had the opportunity to learn about a skinny pig, giant African snail, white pygmy hedgehog, giant African millipede, leaf insect, ball python, crested gecko and much more! Angela was extremely knowledgeable and we had a fantastic learning morning lots of facts. 

Year 3

As part of British Science Week, Year 3 have been exploring plants and their growth. We began by refreshing our basic understanding of the parts of plants and their uses. We created diagrams in out books of the functions of each plant part and then created plant life cycles representing the continual growth and life of plants. We moved on to discuss different types of plants and looked at the plants that we can eat. We sorted them into the following categories: fruit, vegetables, herbs and plants we don’t eat. When we had a more secure knowledge of plants, we took part in a class investigation. Mrs Mahone’s class looked at how light can affect plant growth and Miss Brook’s class looked at how water can affect plant growth.  We worked together to look at the variables within the investigation and discussed how we can make the test fair. The children then all recorded their own prediction using their understanding of how plants grow well. The children will be responsible for watering their plants daily and keeping a log of growth within the next few weeks. Once we have our completed findings, the children will draw upon their knowledge and information gained to record a conclusion.

Year 4

This year, Year 4 had great fun celebrating Science Week.  As the theme was ‘growth’, we grew our very own crystals!  We really enjoyed weighing and mixing all of the ingredients.  Then, we had to wait and observe the changes.  When we came into school the next day, our crystals had grown.

Year 5

As part of our British Science Week, year 5 have looked at our carbon footprint and discussed how reducing this will help our planet to grow and flourish.  We split into three groups and each looked at a different area.  These were water consumption, food miles or clothes and sustainability.  We then returned to classes and discussed what we had learned. We worked scientifically by asking relevant questions, reporting our findings orally and making careful and systematic observations.
We now understand what carbon footprint is, understand ways we can save energy and water, understand how food miles impact the planet and understand how clothing choices impacts the environment. All of year 5 have made a pledge to change 3 things that will help reduce our carbon footprint.

Year 5 have created a plant wall garden as part of our project for British Science Week. We have carefully thought about how we can make it sustainable and reduce our carbon footprint.  The planters were made using recycled plastic bottles.  We have planted herbs in our garden which we hope can be used by Mr Bradwell in the school kitchen and by us when we look at how plants reproduce in our next science unit.  We decorated our bottles, filled them with compost then planted our seeds.  Finally, we watered them.  We will be checking on them regularly and monitoring their growth over time.  

Year 6

Miss Young and Mr Marley from Redhouse Comprehensive joined year 6 for Science Week. We looked at bacteria that the staff had grown from swabs from different places around their school. We knew bacteria grows because it is a living micro-organism. We looked at pictures from petri dishes grown from the different places and tried to match them up with their labels-we were shocked to see the phone case and key board produced the most! The taps and sinks in the toilets produced the least and this shocked (and reassured) us too!

We then played a science version of Among Us to explore how fast bacteria and infection could spread. Two anonymous people were infected and we had to share solution from our boiling tubes with the rest of the class. We then added iodine to our solution and black meant we were infected, brown meant no infection. We were shocked to see how quickly the infection had spread! We were able to narrow the suspects to 4 of us but couldn’t identify the actual infectious! We had a great session and cannot wait to get to comp to do even more exciting things!

Whole school ‘Curly Wurly’ challenge

Did you know that the Guiness World Record for a Curly Wurly stretch is 4.26 metres? It was accomplished under three minutes by Tracy Sullivan in 2015!
During Science week, each class in school took part in a ‘curly wurly’ challenge to see who could stretch their ‘curly wurly’ (we used play-doh) the furthest! We made sure it was fair by ensuring we all weighed out and used the same amount of play-doh (26 grams) and that we timed ourselves when rolling out and stretching the play-doh (3 minutes). We then took measurements of our play-doh after the 3 minutes using different pieces of equipment. Prizes were given to the winners from each class. The overall winners in the whole school were Lucas Hubbert and Jayden Tumwijukye with a whopping 113.5cm!

Science club make rafts!

07.03.22 – Today, science club were challenged to design and make a raft that floats. We talked about floating and buoyancy and then investigated the question ‘What shape of raft will hold the largest number of objects (marbles) before it sinks?’

Science club investigate the human body!

28.02.22 – Today, science club investigated the questions ‘ Do people with longer arms throw further?’ and ‘Can people with longer legs jump further?’
We worked in groups to plan our investigations and answered the following questions: What do we want to find out? What will we change? What will stay the same? What will we measure? What equipment will we need? What do we predict will happen?
We then conducted our investigations and recorded our results in a table. We used our results to discuss the questions: What do our results show? What would you do differently if you did this investigation again? Do you think this investigation was a fair test? Why?
As you can see on the photos, we had lots of fun!

Science club building bridges!

14.02.22 – Today, we were set the challenge of building a bridge over a river. We needed to work as a team to build a solid structure. Miss Slater was so impressed by our wonderful communication skills and resilience.

Science club eggnauts challenge

31.01.22 – Today, our challenge was to design and build a vehicle that would protect our eggnauts (raw eggs) from the perils of re-entry and see if our eggnauts could survive without cracking when being dropped from 2 meters.
We were only allowed to use:
          4 sheets of paper
          20 straws
          15 wooden sticks
          2 metres wool
           3 rubber bands
          Masking tape
Questions we had to consider:
1.  How can we protect the Eggnaut?
2.  What forces are acting on the Eggnaut?
3.  How can we slow the Eggnaut down?
4.  How can I make sure it lands on the target?

We then dropped our vehicles with our eggnauts in from a height of 2 meters to see which of our eggs would survive. We found that the vehicles which were heavier and that were shaped more triangular survived the fall as they fell slower due to more air resistance.

Science club apple oxidation experiment

17.01.22 – Today we worked in groups to test different liquids to see if they can stop the oxidation process of an apple. We learned that apples (like all fruit) contain an enzyme that works with the cells to keep them alive. When we cut open an apple, we damage the apple cells and let in oxygen from the surrounding air. The enzyme reacts with the oxygen, turning the apple brown. This process is called oxidation. We tested plain water, salt water, sugared water, honey water, lemonade, pure lemon juice, apple juice and orange juice to see which (if any) would stop the oxidation process. We concluded that the pure lemon juice was the best at stopping the oxidation process.

Science club create fireworks in a glass!

10.01.22 – This week, Science club had fun trying to create fireworks in a glass. We mixed various colours of food colouring and oil. We then poured what we had mixed together into a glass. We then waited for a ‘firework’ display to start.

Crest Award winners

A huge well done to the children who attended Science club in the Autumn term. They completed a range of different Science activities which gained them a CREST Award.

STEAM event

Some of our amazing year 5 and 6 children visited the Beacon of Light for a STEAM (Science, Technology, Engineering, Art and Maths) event. We had lots of fun using Lego, Sphero educational kits and robots. We had to complete different challenges using our coding, problem-solving and computational thinking skills!

Year 6 investigating beaks and evolution…

As part of our evolution and inheritance topic we have looked at beaks from a range of birds in South America. We looked at a dip netting beak (a spoon), a coniferous seed eating beak (scissors) and an insect catching beak (tweezers). We had a range of foods too: marbles (to represent hard nuts and seeds), cocktail sticks (stick insects), elastic bands (worms), marshmallows (berries and peas (soft fruits). We all chose a type of beak and predicted the foods we would be able to pick up-we had great fun and there were a few surprises too!

Year 6 micro-organisms

We have learned a lot about micro-organisms and we have started an investigation that shows us what they look like and how fast they grow in different conditions. We rubbed our hands (and bacteria) all over some bread and left it in 3 different places (a warm place, a cool place and a dark place). We have made predictions and cannot wait to see it start to grow! We also looked at how fast germs and microbes can be spread using green paint and a little imagination!

Science club have been making and testing glue

15.11.21-This week, Science club were given the challenge of creating glue. We made three different types based on three different recipes, putting our measuring and observation skills to the test. We then had to test the glues to see which was the strongest, the most waterproof and the easiest to remove from material (in case it spilled onto our clothes). Things got very messy but we had loads of fun!

Science Club nest building

08.11.21-This week science club have been hard at work building nests. We were each given a “beak” and were only allowed to pick our materials and make our nests using this beak. We weren’t allowed to use our hands. We watched some videos of different species of birds building their nests for inspiration before we began. We then tested our nests against different weather conditions such as wind and rain.

Spooky Science club!

01.11.21-This week, science club celebrated Halloween with a carousel of spooky STEM activities. We made ghost towers, exploding pumpkins, completed a Halloween density experiment and made bubbling slime!

World Space Week 2021

October 4th-9th was world space week in school and we have been focusing on two very exciting themes: Women in Space and Mars. In school, we have completed some amazing work and investigations, some can be seen below. Some of us also took part in homework challenges linked to these themes and our teachers have been blown away by some of the wonderful pieces of work that we have completed at home. Each year group also nominated a space scientist of the week and they received a certificate in our celebration assembly on Friday.

Juice up your rocket competition 2021

We have all recently taken part in a school competition to design an image for the nose of the Ariane 5 rocket which will begin it’s journey to explore Jupiter and it’s moons in 2022. Our school council chose their favourite artwork from each year group and these will be sent on to the ESA (European Space Agency) who will choose the overall winner from hundreds of children’s entries! We are keeping our fingers crossed that one of our designs is chosen but we had such a lovely time learning about the fascinating planet of Jupiter and creating our designs. Have a look at some of our wonderful work and our fantastic winning entries…

Science Week 2021

Take a look at some of the wonderful work we completed during our 2021 Science Week. The theme was ‘innovating for the future’ which we thought was extremely relevant at this current time and gave us the chance to explore some of the amazing recent advancements which have happened in the scientific field including vaccines. Every year group completed some amazing work based around this theme.

Beat it germ fest!
