Science Club

Video Prospectus
In Science Club we run a different experiment each week. This half term the children are from Key Stage 2. 

9.10.2014: This extra science club was to investigate osmosis and the movement of water from an area of low concentration to one of high concentration to even the two areas out. We looked into this movement by trying to make Gummy Bears grow in water. 

Each of us had a differently concentrated solution of water and salt, water and sugar, and water. We all used the same amount of water (100ml) but changed how many spoons of salt or sugar we put into our cups. We also had a control group of Gummy Bears which went into empty cups.


The experiment was timed and after 20 minutes the bears were removed and placed onto a physical results table to see the difference between the sizes of the bears.


We saw that all of the bears had grown in size compared to the bears that were kept in dry cups.


After a little research, we concluded that the water had moved into the gummy bears because the concentration of sugar inside the bears was higher than that of the solution outside of the bears. The gummy bears in the salt solution did not grow to be as big as the bears in the plain water because the water was needed to dilute the salt solution in the cup.



7.10.2014: This week we were learning about clouds and how they are formed. First we made a cloud in a bottle by mixing water vapour and smoke particles together.


We then made rain by using water vapour (from a kettle) on a cold surface (a metal tray). When there was too much condensation on the tray it fell like rain drops.

We then discussed different types of clouds and how they are formed at different heights in the atmosphere. We made a cloud viewer and used it to work out what type of clouds were in the sky today.

      

23.9.2014: This week we have been investigating reactions including the reaction between bicarbonate of soda and vinegar. The challenge was to make a piece of spaghetti dance in the cup using the bubbles from the reaction. 


The children were given minimal instructions and a few resources they would not need. Most children decided early on to use vinegar and bicarbonate of soda to make their bubbles. Finding the right ratio to use was the tricky bit. We worked out that the spaghetti would need a slow reaction to allow it to dance. So the children used the vinegar and bicarbonate of soda sparingly. The result was FANTASTIC!
