Conductors and Insulators

This week’s lesson in Science involved learning about conductors and insulators. The children were given electrical equipment and lots of different materials and were told to predict and test for which materials were good conductors and which were not. They found that materials such as metal drink cans and foil made excellent conductors.

Electrical Circuits

This term in year 4, we have been learning all about electrical circuits. The children worked in groups to make a doorbell and to power a light. This week, we gave the children citrus fruits to see if they could use them to power a circuit. To their surprise, they were actually able to create electricity using the citrus fruits with copper pennies, zinc screws and crocodile clips. An incredible discovery had by all!

Travelling Sound waves

Robins have completed their topic of Sound this week, and they had great fun discussing and recording how sound can travel through liquids, solids and gases. There were various items laid out around the room and the children had to carry out activities to decide how well sound waves travel. They then  recorded their findings. We had dancing sugar, tuning forks on water and conversations taking place through a balloon. It was great fun, and the children learnt a lot of new knowledge.

Low / High pitched sounds

In science this week, we’ve been focusing on low and high-pitched sounds. We put lots of different equipment around the room and the children had to make noise with it and describe what type of pitch it had. They also needed to try and make a new sound with the object, in order to change its pitch.

Catching Sound Waves

Last week, year 4 started their topic of Sound. The children learnt why sounds are made and how certain ways of hearing, improves the ability to catch sound waves. They went outside in their pairs and listened to each other shouting across the playground; firstly standing with their arms by their side, then cupping their ears and finally, by using a cone to aid their hearing. They are now writing up their findings in order to see which was the most effective method across the class.

Super Senses!

This week, Robins had their first science lesson in the new topic of ‘Animals Including Humans’. They were learning all about their digestive system; in particular the job saliva does in helping food to be digested.

They carried out an experiment to see if not being able to see or smell, effected their ability to recognise the flavour of a sweet. They soon realised that their senses play a huge part in their ability to recognise flavours. They can now also recognise the incredible job our taste buds do to recognise flavours when we’re eating.

Classifying real live animals!

In a world so wide and full of delight, I learned about creatures, both big and slight. With curious eyes, I explore each day, Discovering how living things hold sway.

First, let’s talk about reptiles, you see, Slithering snakes and turtles are they. Scales on their bodies, like a shiny coat, They crawl on land and can even float.

Amphibians are next in my rhyme, Frogs and toads, having a splendid time. They start as eggs in water so cool, then turn into tadpoles, that’s the rule.

Mammals are furry, warm-blooded and dear, With mothers who nurture and hold us near. Dogs, cats, and humans, just to name a few, We feed our young with milk, that’s what we do.

Lastly, we have fish, living in the sea, With gills to breathe, how amazing they be! From tiny goldfish to great big whales, They swim with grace, tales of watery tales.

Living things, so diverse and grand, Each with a role in nature’s hand. Reptiles, amphibians, mammals, and fish, Teaching us lessons, fulfilling every wish.

So let’s appreciate every living being, Protect their homes, the rivers and the green. For in this world, where we all coexist, We find beauty in nature’s magical twist.

Fun Fear Fun! What can I say? It’s been a very busy summer term with so many amazing activities. Today we had the opportunity of classifying live animals and having a full hands-on experience! Lots of us haven’t handled these animals before and persevered! Mr Lo had to put on a brave face when holding the lizard! haha.

We also talked about the importance of habitats and why it’s important to save the rainforests.

Leave a comment and let us know which animal you enjoyed the most!

Mammals and Birds

Robins have been busy learning all about mammals in their science class 🐾. Today, they headed outside to spot some birds 🦜 too!

Not only did they get to enjoy the fresh air and sunshine ☀️, but they also got to see these incredible creatures up close and personal 🤩. We were thrilled to see so many different species of birds, from tiny sparrows to majestic magpies 🐦.

Fun Facts

Warm blooded animals need to eat a lot more food than cold blooded animals. This is because extra energy is required to keep their bodies at a constant temperature. 

One way warm blooded animals are able to keep a stable temperature is by having  more fat on their bodies. This provides a layer of insulation to the internal body parts. Warm blooded animals often have hair or feathers on their bodies which gives further insulation.

When warm blooded animals get cold, they shiver. The series of contractions warms their muscles and in turn the rest of their body.

Extension: Can you remember which are cold blooded and warm blooded?

Habitats

This half term in Science we are looking at classifying living things and understanding their habitats.

Our first lesson recapped prior knowledge on habitats. Habitats are the environment which plants and animals live. Some species of plant and animal are able to live in multiple habitats, while others have adapted so that they can only live in one type of habitat.

VLOG: Electronics

Robins were extremely impressed with Isla’s video log on using her new electronics kit. She demonstrated her knowledge learnt on electrical circuits and has shown confidence in speaking aloud. Well done ISLA!

P.S Another shout out to our Robins football team! Well done!!!

Diluting and Dissolving

In science this week the children have been learning about diluting and dissolving.

Dissolving is a process in which a substance known as the ‘solute’ (e.g sugar) dissolves in another substance known as the ‘solvent’ (e.g water). The solute is completely broken down from larger molecules into smaller molecules after contact with the solvent.

We tested out whether a solid was soluble or insoluble by mixing it with water. Soluble solids included sugar and coffee granules. Insoluble solids included sand and a paperclip!

For diluting, we carried out an experiment to investigate how adding water affects the taste of squash.

Trying out different concentrations of squash!
