Today, Robins have been learning about circuits in their Science lesson. They were eager to use the equipment and experiment in making a successful circuit, to make a light bulb work. Lots of children worked independently, thinking carefully about what was needed to make the circuit work. Robins displayed excellent team skills all working together and helping each other.
Besides enjoying an interesting trip to the Sikh temple this morning, Robins have “virtually” travelled around the world this afternoon. The children were truly amazed to visit the Seven Wonders of the World, the Egyptian pyramids and Sphinx, the ocean and outer space. Using special visual equipment provided by Google, children were able to look around all these places in 360 degree format. This was such a fantastic experience!
Budding scientists in Robins class have enjoyed conducting experiments over the last few weeks to investigate states of matter. They have learnt matter can be liquid, solid or gas and that these can be changed by melting, freezing and boiling.
First, Robins had to find out whether gas weighed anything. Four different full fizzy drink bottles were weighed and then shook for a whole two minutes. Then the bottles were weighed again to discover whether they were lighter. Before the experiment, Robins made their predictions and discussed how to make a fair test. Robins found out about Joseph Priestley, who invented the idea of adding carbon dioxide to drinks to make them fizzy.
The next week, Robins were very excited to carry out an experiment involving chocolate! The classroom smelt like Willy Wonka’s factory! The children were set the challenge of finding out which temperature melted chocolate the quickest. It was very exciting to watch the chocolate melt right before our eyes! We found out the hotter the water, the faster the chocolate melted!
This week, Robins had a carousel of activities and experiments to discover many aspects about water. Children watched how the state of water changed as it boiled and what happened to the steam when collected. They also made observations of what processes occurred when ice cubes were placed in a cling film covered bowl of warm water. They also watched and compared what happened to two glasses of ice when one glass had a teaspoon of salt added to it.
The children answered questions, made observational diagrams and engaged in an interactive computing game about states of matter.
Today, Robins have been identifying how animals and humans look like their parents. They discovered three facts that living things, not born from eggs, have in common.
1. They have fur or hair
2. They have legs.
3. They are tiny copies of their parents.
Next, the class played a game where one child named a living thing and their partner had to decide whether it was from an egg or born alive. Robins were able to list living creatures that had been born alive and also some from eggs.
Finally, they created a list of living creatures to research which they were unsure about. These included spiders, crabs, chameleons, bats, wasps, whales and anacondas.
After the week off school, Year 4 Robins were eager to examine the egg experiment results! They were not disappointed!
Willing volunteers with strong stomachs, took it in turn to smell, feel and examine the eggs that had either been in water, milk (unrefrigerated!), vinegar, coke, orange juice and blackcurrant squash.
The egg which had been in coke was dark brown in colour and had a build up on the egg shell which could be wiped off – imagine what damage it can do to teeth! Surprisingly, the sugar free blackcurrant squash had also damaged the shell and white, chalky bits were breaking off the surface. The egg in orange juice was also the smelliest! It was soft and rubbery like the egg in vinegar but had lots of orange shell flaking off. It looked like it was coated in soggy cornflakes!
The children recorded their results and findings and explained the reason milk and water caused the least damage to teeth was because they did not contain sugar or acid. Robins concluded they would be wise to stick to these drinks in the future to look after their teeth.
Year 4 Robins were really excited when our local dentist – Dr Zarandi, visited our class to give a presentation all about teeth. She brought lots of visual props to enhance her explanations about the structure and care of teeth. She gave the children lots of advice about how to look after their teeth. She was really friendly and happy to answer the many questions Year 4 asked! The children were especially inquistitive about anaesthetic and braces!
Afterwards, she kindly gave every pupil a goodie bag including toothpaste, a disclosing tablet, teeth cleaning chart, a sticker and information about Bells Lane dental practice. The children really enjoyed this special visitor in class which really brought their learning to life!
This week, Robins started their new science topic about teeth. They got the chance to handle and examine a very large set of model teeth, teeth casts, braces and real false teeth, which created a buzz in the classroom! Through class discussion, they created a mind map of known facts about about teeth and afterwards, complied some questions about what they would like to learn and find out about teeth.
During Science today with Mrs Knipe, Robins were learning about the water cycle.
Mrs Knipe did an experiment using a glass of hot water with a tin foil container full of ice cubes on the top of it.
The outcome of the experiment was that condensation formed in the glass. This happened as a result of the heat turning the liquid into a gas which created a ‘cloud’ as it hit the cold tray of ice cubes and formed condensation.
