Thinking about growth

This year’s theme for British Science Week was all about ‘growth’. This got us thinking here at Hedworth Lane what could we grow inside the classroom? We decided that we were going to grow our very own grass heads that we could look after and take care of. First, we designed the faces on the pots that would become our little characters. Then, we planted the seeds and waited. We had to wait a whole 7 days for the first signs of life to appear – which isn’t too long really but it seemed to take ages. We waited, watched and watered for another two weeks and by then our little grass heads needed a hair cut! We used our math skills to measure who had the longest grass ‘hair’ in the class and then we got to work giving them all a trim – how exciting! Another two weeks have passed since and our grass heads need another hair cut already… We have produced an army of super growers ! Have a look for yourself below.

British Science Week 2022Β  #BSW22

Upper Key stage 2 had a fantastic time this week completing all of the challenges set by their teachers during British Science Week. Firstly, we used our prediction skills before finding out how many droplets of water we could fit onto a 2p coin before it spilled over the edge onto the paper towel beneath. Next, we tested the relationship between our eyes and our brains with some awesome optical illusions. We built amazing structures out of books that seemed to defy gravity and balance on a piece of paper ! After that, we met the Potato Fish, who seemingly floated in the blue water and didn’t sink to the bottom of the bowl – the children loved explaining to the teachers how this one worked! And finally, to gasps of delight, the children tested the effects of air pressure on a ping pong ball using a hairdryer. They then had a go with a Malteser and their mouths to see if the advert on TV really worked? We are very pleased to report that it did! Check out some of our pictures below… Now that’s Super Science !

Life Cycles – The miracle of metamorphosis

Year 5 and 6 had the very important job this year of looking after our very own caterpillars as part of our Lifecycles topic. We knew that these insects were very special because they undergo a special type of transformation called a complete metamorphosis. We watched the caterpillars go through the first stage -called the eating stage – where they went from tiny to huge before our very eyes. Then they developed a hard outer shell around them known as a pupa or chrysalis. Finally we watched each of the caterpillars emerge as a completely new insect – a butterfly ! We looked after them for a day or so until their wings became hard enough to fly and we released them into the wild to start the lifecycle all over again. Now that’s magic!

Life Cycles – Living Things and Their Habitats

We have thought about how plants and animals reproduce.Β  We closely examined a flower and identified the different parts and their functions.Β  We found out about asexual reproduction in plants such as potatoes and strawberries.Β  We then considered gestation times for a variety of creatures.Β  Did you know, the longer a creature’s life expectancy, the longer the gestation period is likely to be?Β  Finally, we considered the ways in which animals are adapted to their habitats in order to maximise survival chances and produce offspring to carry on the species!Β  We learned about Darwin’s Finches on the Galapagos Islands and the differences in their beaks and food choices.Β  We used a range of equipment as beaks.Β  Have you ever heard of a Scissorbeak or Pegbeak bird?Β  We have!Β  We collected a variety of food types and had lots of fun, recording our answers in table form and interpreting the data to draw conclusions.

Properties and Changes of Materials

As part of this topic, the children have had lots of experiments to conduct during our science lessons. This week we have been separating materials. Firstly, we had to select the correct equipment for our experiment. Next, we carried out the investigation using techniques such as filtration, magnetic separation and evaporation. We really enjoyed finding out which technique worked best for each mixture.

Properties and Changing of Materials

Last week we looked at different materials and thought about their properties. We discovered that materials are chosen for particular products and jobs because of their properties.

This week we started to think about special properties of materials. We investigated whether some solids were soluble or insoluble (dissolved or not).

We tested lots of different solids including gravy, rice and sugar.

Next, we thought about factors affecting dissolving. The children came up with lots of ideas such as temperature, number of stirs, speed of stirring and size of particles.

I demonstrated, with the help of the children, how temperature affected the rate of dissolving. We created a line graph of the results.

 

Earth and Space

Year 5 and Year 6 have been learning about the phases of the moon this term. We looked at the different shapes that the moon appears in the sky and worked out a formula to tell if they’re ‘Waxing’ (growing bigger) or ‘Waning’ (growing smaller) . We then tried to find out why sometimes we can’t see the moon at all in the sky. The children learned that the moon hasn’t really disappearedΒ but is just between us and the sun so we can only see its dark side. The children learned a song to help us remember all eight phases then used their knowledge to create their own moon phase art. We think they look out of this world !

Circuits and Electricity

Children in Upper Key Stage 2 have learnt about several ideas relating to electricity this half term. They are able to draw simple circuit diagrams and label them. They are alsoΒ aware of the history of the discovery of electricity, electric current and voltage.

This week the children conducted an experiment to explore the following question:

What effects do differing voltages have on a electrical component in a circuit?

The children tested how changing the voltage affectedΒ motors and bulbs in a complete circuit.

The children made predictions, collected results and formed conclusions.
