Year 5 have continued with their science investigations into materials and their properties. This week, they have been testing materials such as salt, sugar and gravy to establish whether a material is soluble or not. They then had to carry out a series of investigations to establish whether a different temperature of water would affect their results. Tomorrow they will analyse their results and draw a bar chart to represent their findings.
Continuing with the topic of Materials and their properties, year 5 have planned and carried out an investigation into which materials would be suitable for use in football floodlights. They set up their circuits and chose various materials to test. They studied the brightness of the bulb to see which material was the best at conducting electricity. They then discussed their findings and offered their recommendations. Super team work year
Year 5 have been busy learning about materials and their properties. Last week, they were testing materials to see which was the best lining for a lunch box.
In groups, the children worked together to carry out a fair test of materials such as: sponge, cotton wool and bubble wrap. They tested each item for magnetism, transparency and permeability as well as flexibility and hardness. Ice cubes were placed into glass jars and each jar was wrapped in 1 particular material. They then timed each ice cube to see which material offered the best insulation. This week the children recorded their results and decided which insulator they would choose to use for their football floodlights.
Year 5 have started their new topic this week – Materials & their Properties. They began by feeling various objects hidden under a cover, and used a range of words to describe what they could feel. They then had to match descriptions of words to words such as permeable and transparent. It was a lot of fun and the children learnt a great deal.
Year 5 have ended their forces topic with an investigation into friction. They were asked to test various materials to see which one would be the most suitable material for a set of breaks for a tricycle. They had to decide which variables they would change and which ones would need to stay the same, in order for a fair test to be carried out. It was a fun filled lesson and the children now have an excellent knowledge of both water and air resistance and friction.
Year 5 have been busy investigating air resistance by designing a parachute. They had to consider the variable they wanted to test ie: material, shape of parachute, length of strings etc and then ensure they kept all the other variables the same. They then dropped their parachutes from the same height to see if their predictions were correct. Have a look at our fun videos and photos.
On Friday the children in year 5 learnt all about how objects have a mass and how this can be measured using a newton metre. They had various objects to weigh and recorded the mass in Newtons as well as the weight in kg. They were also able to spot the relationship between both the mass and the weight.
