Floating Needle Experiment

Did you know you can make a compass out of a needle? 

Bluebirds did exactly that in science today, they used their investigating skill to find out which way north is, only using very simple equipment.

In small groups the children were given a bowl of water, a leaf, magnet, and a needle.

How to do the experiment:

First, fill a bowl with water.

Then rub the needle with the magnet 50 times. 

Carefully, float the leaf on the water.

Place the needle on the leaf.

Finally, watch the magic happen. 

What do you think will happen ?

It’s a simple experiment and a great way to introduce the concepts of magnetism, magnetic poles and the Earth’s magnetic field.

Exciting Science!

Bluebirds have been investigating which materials can shield a magnetic field. They looked at what a magnetic field was and how it works in the world around them. They looked at a train in Japan called the Maglev Train and how the magnetic field help to propel it across country. They also learned how magnets can push or pull each other using the correct terms, repel (north to north or south to south )and attract (north to south or south to north).
They used a paper clip attached to thread and a magnet attached to the table.
Carefully they set the paper clip near the magnet but not touching it, this created their own magnetic field. Bluebirds placed different materials between the magnet and the paper clip, looking to see which one would break the magnetic field.

Magnets

The children looked at different magnets and their properties. They looked at their different uses such are in toys, fridge magnets and medical uses.
The children even discovered there was a cow magnet and what it was used for.
They found out that even though we do not think of magnets as useful, they had so many  uses in everyday life.

Forces

This half term our science topic is forces. We looked at how magnets would react differently to materials such as paper, nails, paper clips, aluminium foil and other objects.
We spent time exploring how magnets reacted to each other by pushing each other apart (repelling) or pulling each other together (attracting).

Observing rocks

Bluebirds learnt about the physical, biological and chemical effects of weathering on different types of rocks.  The class set up an experiment and made predictions about whether limestone, chalk, pumice and brick would go darker on the surface once water had been added or whether it would dissolve and predict if the rock would be heavier when we reweigh them tomorrow.

Investigating soil

Bluebirds enjoyed conducting a science investigation this afternoon, to find out which types of soil samples they had.  They studied the colour, smell and texture.  Then they tested and measured the amount of water that drained away from each soil sample.  Well done Bluebirds you correctly identified clay soil, Sandy soil, chalky soil and peat!

Branching Databases

For the last two weeks in Bluebirds class we have been doing Computing in our topic lesson. The children have been using J2E Branch to create a branching database. This software included asking lots of yes and no questions which we did at the beginning of every lesson.

Before we started using the branching software the children started with organising different things into groups. The children worked in pairs and organised things such as sweets into colours and patterns. They also cut out lots of different food types and grouped them accordingly. A lot of the children put them into healthy and unhealthy food groups.

Then it was time to get the laptops out and have a go for ourselves, the children had options of animals, food, dinosaurs and aliens. They have to drag all the objects across and then begin to organise them through asking yes or no questions.

Reflective Surfaces

In our Science lessons this week we have been learning about light. The children have learnt that dark is the absence of light. They have also learnt that the sun is the biggest source of light as well as other sources which include lamps, televisions and fire.

In Thursdays lesson the children were experimenting with different materials and they were trying to find the most reflectivel material. The children were given five different materials to experiment with, these included, tin foil, cellophane, paper, plastic and tracing paper. They were working together with their partner using a reflective tester made out of a piece of paper with a hole in it and a torch. They were then shining the torch through the hole to the material and seeing if the reflection bounced back onto the paper and a lot of the children identified successfully that the cellophane was the most reflective material.

Once the children completed this experiment they were able to move onto the second activity of the afternoon which was to design a reflective book bag. The children were able to identify and explain why the use of high visibility jackets and bags were important. Most of the children decided they would use cellophane to design their book bag with.

Here is Firas’ brilliant design, he opted for a colourful book bag and chose the most colourful and bright material so it could be reflected!

Daisy B opted for a pink and blue book bag, however she chose tin foil as her material for her book bag as that is what Daisy B found out through the experiment. She described the tin foil as being shiny like the high visibility jacket!

We have had a brilliant first week learning about Light and next week we will be looking at making shadows!
