Welcome to our Science Club page! 


Our science experiment today was all about taste - we explored this sense using the different parts of our tongue and taste buds called papillae which allow us to differentiate sweet, salty, sour and bitter flavours. As we are a healthy school, we investigated different fruits to see which taste buds on the tongue the fruits activated. We concluded that most fruits have either a sweet or sour taste!


We then followed up our experiment with an acidity test, by creating fruit volcanoes. We used the fruit's natural juices combined with food colouring, washing up liquid and baking powder. The more acidic the fruit, the bigger the eruption! Our final conclusion after testing lemons, limes, pineapple, grapefruit, oranges, apples and berries was that the lemon was the most acidic! 


In light of the recent COP26 conference, in science club today we explored an alternative way of storing water other than using plastic bottles, in order to reduce our carbon footprint! The children had great fun investigating molecular gastronomy and created edible water bubbles to store water in. Whilst the children determined they weren't the most stable container, we all agreed they were a step in the right direction towards reducing our plastic waste! 


This afternoon we explored the world of colour in a chromatography experiment! We discussed how ink is made up of different pigments and when dipped in water, the pigments separate and travel up the filter paper at different speeds. This allows us to identify which pigments make up a particular ink colour!


Before starting the experiment, the children made predictions about which pigments might appear in different colours of ink. They then began their test and recorded their findings; it's safe to say nobody predicted that pigments of pink and blue would appear in black ink!


Today we explored the concept of density by conducting a lava lamp experiment.


The children used two liquids, water and oil, which have different densities. We added food colouring to the water to make it more visible when the liquids mix. After that, we added antacid tablets, which when dropped into water, fizz and create carbon dioxide. This then causes the water to bubble, moving the denser coloured water through the oil!


The children experimented with different ratios of oil and water, food colourings and and strengths of antacid tablets, in order to achieve the perfect lava lamp effect! 


Science Club took on more of an engineering focus today, with the children designing and building their own towers. There was an added pressure of a challenge and a time limit today - which team could build the tallest, most stable tower in 20 minutes?


We started with a discussion about gravity and how this can have an impact on stability. As a result of this discussion, we decided that a stable foundation would be needed to support the weight of our tower and ensure that it did not topple over.


Before starting to build our towers, we spent some time planning and designing on paper to ensure that we would use our 20 minutes effectively. Then... it was time to build! We used spaghetti and tape as our main resources, although at the end of the challenge the children concluded that marshmallows would have been a much better resource! 


Our experiment today was to see if we could make slime without knowing the quantities of ingredients needed.


Before starting, we discussed the methods we were going to use and came up with a set of instructions to follow. We also created a criteria which the children would use to determine whether the experiment had been successful. 


The children found this experiment particularly tricky, but they persevered and most were able to create a slime that met their success criteria!


Today we experimented with walking water! The children had 6 cups, 3 filled half full with water. We laid the cups out in a row with every other cup left empty. We then chose our food colouring and added it into the 3 cups with water. Next, we bent tissue paper over the cups so one end was dipped into a cup with water and the other end was in the cup with no water. As if by magic, the coloured water travelled up and along the tissue and into the empty cup next to it!


The children were very impressed, but using their scientific minds, concluded that kitchen roll may have made the experiment more effective. They are going to retry the experiment at home and let me know their results!


In Science Club this week we had great fun with our 'Egg Drop' experiment! Our challenge was to investigate which materials would be best for protecting an egg when it was dropped from a height.


The children got to choose their own materials to experiment with, which included cotton wool, water, balloons, straws, cardboard, newspaper and fabric. Some of the materials were successful in preventing the egg from cracking but others unfortunately were not! After making our predictions, carrying out our test and then drawing up our findings, we concluded that cotton wool made for the best protective material. 


Well done to the children, they were 'eggcellent' scientists today!
