Today the Ospreys from P4 and P5 got together to take part in an extended Science Masterclass. We learned all about chromatography. This is a method used to separate mixtures. Very few things consist of a single substance. Most of them are a mixture of different substances. We carried out an experiment to see if we could make it work.
In our experiment we tried to separate the different colours found in felt pens. Please explain to someone at home how it all worked. You may even be able to show them.
Yesterday we were lucky enough to have a visit from Mrs Clisby and some of her colleagues from AMRI, a pharmaceutical company in Glasgow. They discussed what they did at work and how they had to ensure they were working in a sterile environment otherwise the medicines they were working with would have to be disposed of.
One of the sessions was all about bacteria and how it grows. We looked at a variety of samples that had been taken from their workplace. Can you remember what the samples were and which had the most bacteria growing on it. I think a few of you were very surprised! A sample of our door handle was taken – I wonder what the results will be for that when they come back!
The other session was all about filtration. You had the chance to filter glittery water to make it clean. Try to explain to someone at home what the process was. You then had the chance to seal some of the medicine bottles with some really cool gadgets.
What a great session we had! A huge thank to Mrs Clisby and her colleagues. We definitely learned lots.
Over the last couple of weeks we have been learning all about friction in our Science lessons. We have learned about static fiction and air resistance by taking part in some interesting and fun experiments. What is friction? What would happen if there was no friction? Please tell someone at home all about it.
Today we were investigating air resistance and after watching some videos and having an in-depth class discussion, we decided to put what we learned into action. We made our own version of a parachute using different materials of different sizes to see which one had the most air resistance. It is amazing just how much fun you can have with a poly bag!
We have been continuing with our Science topic. This time we looked at the dissolving properties of a number of different materials. First of all we discussed whether the temperature of the water would make a difference. What did we decide? Next we gathered a number of materials and tested whether or not they dissolved. We tried to keep the amount of water and materials used for each test the same. Once we had completed all of the testing we then had to decide whether the material was soluble or insoluble. Can you remember what each of these terms mean? Please tell someone at home what we have been learning.
During our Science focus this term we have been looking at the different methods of separating materials. Can you remember the names of the main methods?
We used the decanting method in class to separate oil and water. We then used the liquids to create our very own lava lamps. Please explain to someone at home what happens and why it happens. It was great fun making our lava lamps however can you remember the science part?
Thank you to our class photographer who managed to snap a few pictures of you in action.
If possible, please bring in a small, empty plastic bottle to school. Please ensure the bottle has been cleaned out, the label has been removed and the lid has been kept. We need one for each person in the class so if you have any extra, please bring them in too.
Last week we made our very own sand columns. First we had to record how we were going to complete the experiment and predict what was going to happen. We then, in our groups, completed the experiment. Can you remember the steps we had to take to make our columns? Please tell someone at home how we did it.
This week we completed our final experiment linked to the water cycle. Using our knowledge of how the water cycle works we set up our own experiment to make rain – or precipitation!
Once again we had to record the method we were using and then show a detailed and labelled diagram of what our experiment would look like. Next we had to predict what would happen. Then we had the fun part ……….. and lots of mess. Please tell someone at home how it all worked. Once we completed the experiment we had to record our results. How did you do do? Did you work out what would happen?
Today we set up our very own water cycle experiment. Before we began our experiment we had to consider what method we would be using: how would we carry out our investigations? Next we had to complete a labelled diagram of how our investigation would look. Finally we predicted what would happen. After carrying out our investigation we left it to work (hopefully) over the weekend and then we will record our results on Monday.
This afternoon you became scientists when you took part in an experiment where you created a rain cloud. Can you explain to someone at home what you did and how the experiment worked? Can you remember what we were trying to recreate? Impress someone at home with just how much you know.
