Year 4 have been experimenting curtains today.
The children were given a scenario;
‘In the summer the sun rises before I need to get up. The light from the window wakes me up and I can’t get back to sleep. I want to buy some new curtains to block out the sunlight, can you help me to decide which fabric will be best?’
The children used the bear cave to explore three different fabrics. They had a white fabric, a purple thicker fabric and a black fabric that was even thicker. They found out some new tricky words, transparent, translucent and opaque and the meaning of them
– Transparent materials let light travel through them in straight lines.
– Translucent materials let some light through, but they scatter light in all different directions.
– Opaque materials do no let any light travel through them.
The children used torches to shine through the different materials and found out that the black material was the most suitable as it didn’t let any light through.
The children wrote these down and then made posters to advertise the blackout curtains based on the experiment. The children had great fun doing this as they included their scientific facts within the posters.
It is safe to safe we are enjoying science week.
Today it was Year 3’s turn to come for the science experiment enterprise with year 4. A few children turned up and had a lovely time exploring what happens when you mix together bicarbonate of soda, washing up liquid and lemon juice.
The bicarbonate of soda, when mixed with lemon juice, is forming carbon dioxide gas. As this fizzes up in the washing up liquid, it creates lots of soapy bubbles – wow! Is science magic?
The second experiment of the afternoon was with Mr Rowe looking at how the air pushes balloons. We thought that the more air that was blown into the balloon would affect how far the balloon would travel.
As you can see by Aly’s face she was rather amazed! Read More
Year Four have had a lovely afternoon. We walked into town with our world book day vouchers and all got to choose a book. It was very exciting and we were very well behaved.
On Friday we had a fun afternoon in Year 4 experimenting the effects of deforestation. It took a lot of setting up.
First we had to ask Mr Rowe to use a sharp knife to cut holes ready in the bottles. We then added the same amount of compost into each bottle. After that we had to label each of the bottles A B and C. We added seeds to bottle A, we added leaves and sticks to bottle B and we left bottle C with just compost in.
Bottle A represented a normal forest, Bottle B represented a forest where the trees had been chopped down and Bottle C represented a forest where everything has been chopped down and the trees have been burnt.
Next we had to use the bottom part of bottles with string attached to put onto the bottles we had filled with compost and the other items so that we could pour the water in and see how it would come through. We took the lids off the full bottles and began to pour water into the top of the full bottles.
We noticed that Bottle A had clear water, Bottle B had water with a slight yellow tinge and Bottle C had water with lots of compost in.
This showed us that the plants hold the soil in place so it does not drain away for Bottle A, the layer of leaves and twigs helps to keep most of the soil in place for Bottle B and there is nothing to hold the soil in place for Bottle C.
We had lots of fun predicting and it was very interesting to see the results.
We would like to wish Oskar, Vaughan and the rest of the Marlfields boys football team the best of luck tonight in their match. We think that the boys from year four look very smart in their school football kits.
Some of the children in Year Four brought in £2 to help raise money towards ‘Restart your heart’. The money is being put towards a Defibrillator that will be kept in school for if anybody suffers a cardiac arrest.
The children went onto the field and were challenged to see how many skips they could do in one minute, Mr Rowe had them working very hard.
As part of keeping healthy for ‘Restart your heart day’ we made some healthy smoothies using skimmed milk, grapes and bananas. The children had great fun working together making them and most of them said they tasted delicious. The children decorated their cups with ideas of how we can keep fit and healthy.
