Beech Class

St Michael's Fun Science Workshop
Beech class had a very practical Science lesson building their own working model of the circulatory system.  They had to think about how they could get their 'heart' to pump the blood around their double loop system using tubing to represent their veins, arteries and capillaries. 
We predicted that the more lamps we added to our electrical circuit, the dimmer the bulbs would be.  To prove this scientifically we worked in groups to use a data logger to measure the brightness of the bulb when there was 1, 2 or 3 lamps in our circuits.  We had to ensure that we kept our test fair and we also repeated our results to ensure they were accurate.  

We begun our work on irreversible changes by exploring what happened when we mixed different ingredients together.  We were excited by the chemical reaction we created when mixing citric acid, bicarbonate of soda and water together.  It fizzed and frothed and we explored how this change was irreversible.

We then worked in our groups to use icing sugar, citric acid and bicarbonate of soda to try and create the perfect tasting sherbet.  It took quite a bit of development (and taste testing), but some groups managed perfect tasting sherbet in the end!

Investigating the best type of vinegar to create the largest chemical reaction.....as we knew we could only change one variable (the type of vinegar), we knew we had to keep lots of variables the same so that our test was fair.

We investigated forces by carrying out some hands on activities.  We experimented with moving jelly cubes using chopsticks.  We then had to try it with oil added to the dish.  This sparked a discussion about how friction was a force that could be very helpful in our everyday lives.
Is there a relationship between the mass and weight of an object?  We used weighing scales and force meters to record our results and then carried out some pattern seeking to answer this question.
Planning our investigations into air resistance.  We experimented with paper spinners and then worked with our groups to decide on what we could change about them.  We are now going to choose one of the variables to change and investigate what happens.
We tried out a modelling activity to investigate inheritance.  We used a variety of different liquorice allsorts and chose one to represent the ‘male’ and one to represent the ‘female’.  We thought about the key features of each sweet and then had to select one, which could be the ‘offspring’ of these.  This helped us to explore the idea that characteristics and traits are passed down from parent to offspring, but normally offspring vary and are not identical.  We had to justify and reason for our choices.
