Year 4 Science: Separating mixtures of solids

Year 4 have enjoyed using sieves to separate different mixtures of solids this week.

We found it really interesting to see how the sieves with larger gaps in their meshing trapped the larger solids, but let smaller ones pass through.

Take a look at some of the photos below showing our investigation.

Can you think of any more groups of three solids that could be separated by sieves with different mesh sizes? Comment with your ideas!

Year 3 Springs!

This week the Year 3s have enjoyed a wonderful introduction to the second half of their Science topic-Springs!

We have looked at a variety of springs of different sizes and we have discussed how they might be used in everyday life. We then investigated what happened when you push the two ends of a spring together and also what happens when you pull the two ends of a spring.

The Year 3s certainly enjoyed the hands on activities!

Year 3 Magnets and Springs

The Year 3s have planned and carried out their very first scientific investigation! They had to plan an investigation into which were the strongest magnets and how they would find this out. The children decided to see how many paperclips each magnet could hold in a chain and some also measured the distance at which a magnet attracted a paperclip! The boys were very methodical when carrying out their investigation and they repeated the experiment to check their results. So which was the strongest magnet? You’ll have to read their results in their Science books!

Skeletons!

In today’s science lesson (Friday 12th October), we were divided into groups of four and set the task of drawing around one person in the group.  We were going to draw our own skeleton. Mrs Sethi accompanied us to the Junior Hall and stuck four pieces of paper together to make a big square canvas for our chalk outline. In our group, Joseph was chosen to draw around. I was enjoying it so much, I didn’t even realize it was a science lesson.

When we finished our skeleton drawing, we labelled it using the correct scientific words. We had to be careful that someone else hadn’t already written what you were going to write. Once everyone was happy with what they and their group had drawn, we all laid out our work of art on the floor and sat down on the wooden benches to look at everyone’s work. I really enjoyed it and I will always remember today’s science lesson.

Year 3 Dental Talk

As part of the Year 3 Science topic of “Teeth and Eating”, Dr Hanslo kindly agreed to come in and talk to the boys about the causes of tooth decay and dental hygiene. The boys listened to a fascinating talk about different types of teeth, layers of a tooth, causes of tooth decay and how to prevent tooth decay.

The boys had an opportunity to look at models of teeth and jaws as well as performing demonstrations of how to clean the teeth correctly. Each of the boys received a dentist’s “goodie” bag at the end of the talk.

Our thanks go to Dr Hanslo for coming into school once again to deliver such a fascinating dental talk.

Year 4 trip to Bestwood Park

 

Last Wednesday, on a warm sunny day, 4C and 4S went on a day trip to Bestwood Park in Nottinghamshire.

It was a 25 minute journey from school in a double decker bus. When we arrived we were met by the guides who led us through the park and through some very tall trees.

The guide told us that there was an old water mill by the lake that had had the stream blocked off to make a path so that people can walk on it.

We continued on this path to go pond dipping which was very good fun as some of the boys caught little fishes, water boatmen, freshwater shrimp and other pond life. These were all caught with nets on long poles and the nets had tiny little holes in them so that little creatures wouldn’t escape but the water could trickle out very quickly.

Our catch was put into plastic tubs and some of the creatures were put into little tubs with magnifying lids which enabled us to see exactly what was in the tub very clearly. The guides put cards on the fence to show and tell us about what we had caught along with each creatures’ food chain.

After pond dipping we were back on the bus for a few minutes to take us to a woodland area to have our picnic. When we had finished lunch, we went into the forest and had to find little bugs and insects – some of which were on the trees, some on the ground on leaves and some in the air flying by – again we had to put them in microscopic tubs so we could examine them closely.

Finally we went into the open grassland and learnt that different types of bugs and insects live in areas that are suitable and help them with their camouflage. In the open grassland we found black and orange millipedes, leaf insects, mosquitos and ants.

To conclude it was a very good informative day where we all learnt a lot about nature which will help us with our science topic at school about habitats.

On the 27th June 2012 Year 4 visited Bestwood Park. We travelled by bus and we were all very excited, especially about the pond dipping.

We first visited the Mill Lake, this is named after a Water Mill that used to be there, and had lots of birds flying around across the lake.   After visiting the lake we went pond dipping -we all had nets and caught lots of creepy crawlies such as newts, water shrimps and fish. We also learnt what the water creatures ate including each other,(yuck!) such as a newt gets eaten by a fish.  We all looked at what each other had caught, some of my friends also caught water lice as well as fish and newts.  After the excitement of the morning we were all ready for our packed lunch.

In the afternoon the lady drove us into the woodland forest and we split into our house groups.  We hunted around the forest for different insects like spiders, beetles and ladybirds and we put them in a magnifying pot to see the patterns and colours more clearly. I didn’t like the spiders, they made me shiver with their long legs which looked even bigger under the magnifying glass. When we had finished, we released them back in to the forest.

Finally, we made the human food chain, the energy comes from the sun to grow the grass then the cow eats the grass through to the humans.  The big predators always end the food chain.

The trip was fantastic and it was really interesting to see the various insects up close.  I would definitely recommend Bestwood Park as it is both fun and educational.

Year 4 Trip to Bestwood Country Park

On Wednesday 27th June, Year 4 visited Bestwood Country Park, Nottinghamshire to study habitats. We left school at 9 a.m. and travelled by bus.  We were all very excited at the thought of pond and river dipping but not at the thought of some of the creepy crawlies we might find.

When we arrived we met up with the insect specialist who did seem to know a lot about insects and mini beasts.  She told us all about the activities we would be doing throughout the day and what insects and plants we might find.  Our expert for the day also explained the history of “Mill Lake”, it is called this because of its early use as a water mill.

After being supplied with nets we headed off to start our first exercise of the day – Pond Dipping. Yousef and I took turns to sweep our nets through the murky water trying to avoid the carpet of lily pads. Whatever creatures found their way into our nets ended up in our buckets. We came across a tadpole with its back legs developed, a small fish, water mites and two scary looking blood worms which we avoided getting too close to.  Luckily the insect specialist was there to help us identify all the creatures we found. She also gave us some useful advice about leeches “never pull them off as this can be very dangerous, they will fall off themselves after they have taken enough of your blood” – nice to know!

Next we had the choice to continue wading through the murky waters pond dipping or collecting bugs from the soil and putting them into specimen pots.  I decided to be brave and get my hands dirty down in the soil.

Later on we returned to the bus and travelled to an area where we had a picnic style lunch on the grass.  I am glad to say that there were no creatures or bugs on the menu; however they seemed to be enjoying my menu.

After lunch we were divided into our houses and set off to explore the woodland habitat to see what creatures we could find.  We found beetles, worms, ladybirds and even mosquitos which we all tried hard to keep away from.  The bugs went into specimen pots where, with the help of the insect specialist, we identified which type of bug they were.  Once we let the bugs go again we headed off to an area in the woods where we looked at pictures and read leaflets that helped explain what the bugs ate, how they survived in the woodland habitat and about the food chain they were part of.

Our final part of the day was spent in knee high grassland.  Once again we found various bugs including ladybirds, flys, ants, snails and more pesky mosquitos.  After a quick study of the bugs close up, we let them return to their natural habitat.

It was a great way to spend a school day even though my skin itched all night and I couldn’t stop thinking about those vampire mosquitos!

Space Centre

On Tuesday 24th April, Year 5 visited the Space Centre in Leicester to support our topic of Earth, Sun and Moon.  We began the day with a planetarium show which taught us all about our solar system.

We were then able to explore the galleries where we learned even more about the planets and were able to experience what it would be like to travel in space in the Tranquility Base.  We also saw a real rocket and were able to present a weather forecast.

Finally, we took part in an Earth, Sun and Moon workshop.  The workshop taught us about the phases of the moon and how seasons change on Earth.

It was a fantastic day out and we all learned a great deal.

Think Tank

On Tuesday 28th May Nottingham High School’s Year 6 boys ventured to the enthralling Birmingham Think Tank. Here we saw many things relating to Chemistry, some of which were extremely interesting and dangerous if done in the wrong manner.

The day started off with a quick Chemistry Workshop; in this we mixed chemicals to inflate a balloon and after that we were lucky enough to make slime using a chemical called Borax.

In addition to this, we were mainly looking at the differences between a solid, liquid and a gas and how they move. A solid’s particles are jammed together allowing them very little space to move, this is why solids do not move. A liquid’s particles are spaced around, allowing them to move and be formed in to different shapes if put in a container. Finally a gas’s particles are even more spread around and bounce off each other very quickly.

Once this had ended we were then split up into our various groups to have an hour’s walk around the exhibitions. This was extremely exciting, we were lucky enough to observe various inventions from the past, the present and what we might have in the future. We then settled to a tasty lunch with our friends.

Soon after lunch we were led to the most exciting part of the day, the Chemistry Show. This was by far the highlight of the trip as we were able to look at the different scientific reactions that occurred when solids, liquids and gases are mixed together. One particularly interesting thing was when the presenter placed helium into bubbles, causing them to drift off to the ceiling. We also observed hydrogen balloons exploding and a fountain made by mixing cola and a mint sweet. The show ended with the creation of monster’s toothpaste!

Overall it was a brilliant day and the current Year 5’s definitely have something to look forward to!
