Bluebirds have now just completed their experiment on how plants germinate. They have followed and observed cress for the last four days to find out what happens to seeds when they start to grow. As you can see all the children have learned so much just through observation. The children looked at the stages the seed went through, from the seed swelling, then splitting and finally the shoots emerging from the seed pod.
Amudha: I liked the experiment watching how the plant germinated. It changed day by day and we got to watch how the shoots grew longer.
Bluebirds are taking part in an experiment in science to show how seeds germinate. They have paired up to grow cress from seeds and, for the next few days, they will examine their seeds to observe how they grow and look.
Today Bluebirds learnt how plants disperse their seeds to enable new ones to grow. The seeds are dispersed so they are not near the parent plant because otherwise both parent and young plants would be competing for nutrients and water. The class looked at pine cones and sycamore seeds.
Mrs Parry cut open a poppy seed head from her garden so the we could see the seeds inside. We all enjoyed watching films of seeds being dispersed by explosion. We all made 5 different sized paper versions of a sycamore seed and tested how long they took to land on the floor. We made sure we used a stopwatch and held the paper at the same height each time. The results were surprising!
Bluebird’s topic in science is all about plants. The children have been learning about what plants need to survive and the job of each part of the plant.
In today’s lesson Bluebirds examined the roots of an onion carefully. They discussed what they thought the job of the roots were. They also talked about what would happen to a plant if it had no roots; the fact that it would die or fall over without them.
A plant needs roots to anchor it to the ground and also to suck up water and nutrients from the ground around them.
Bluebirds today looked at how the sun can harm our skin and eyes. They carried out an experiment showing how different factor sunscreen can help to protect their skin. They used ultraviolet light sensitive beads and an ultraviolet light source.
First, they took 4 beads and three dishes of different sun factors; 15, 30, 50. Then they coated three of the beads in each of the different factors with the last bead left with nothing. Next, they placed the beads under the ultraviolet light and observed how the bead reacted. Finally, they recorded their observations.
Today’s experiment was very fun because we learned that wearing sun cream is important – Elias
I thought it was exciting because some beads changed fast showing the higher the factor the better the protection – Ryan
Year 3 were making periscopes today in Science. They were learning about how light bounces from objects, especially with mirrors. They learnt that to make a periscope you must have two mirrors opposite each other at an angle of 45 degrees.
Here is a link to help you make your own periscope at home:
Bluebirds had a great science lesson this afternoon experimenting with mirrors. They took it in turns to be their partner’s mirror image. They then used mirrors and curved them to make concave and convex mirrors to see what happened to a star shape. Last of all, they enjoyed Preparing mirror writing and then checking it afterwards.
Bluebirds had a fun science lesson. They were learning about light and how different kinds of material can block the light.
The children learned the rocket words and the meaning of each word:
The children made shadow puppets out of card by carefully cutting out their chosen animal. They then placed a lollypop stick on their card. Mrs Parry brought in a shadow puppet theatre she had made and then placed a light source behind it. The children then placed their hand made puppets between the light and the theatre creating a shadow.
When Bluebirds had experimented with their puppets, the class talked about what they had learned. They discussed how the light had been blocked because the card was opaque and no light could pass through it.
Why not have go at this at home and see how much fun it is!
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.
