Year 4 enjoyed their final experiment of the week last week which was ‘Volcanic Eruptions’!
They followed instructions to complete the experiment and it worked.
We found out that without the washing up liquid the volcano wouldn’t have erupted.
Today for Class 4’s enterprise it was Class 5’s chance to come and take part in an experiment. The experiment was to see if they could make the worms wriggle and they succeeded.
First they put the worms into bicarbonate of soda and water for 30 minutes.
Next they got a glass half full of vinegar and placed the worms inside.
The mixture started to fizz and sure enough the worms began wriggling.
This was so much fun and we found out that mixing bicarbonate of soda with acidic vinegar creates bubbles of carbon dioxide gas. As the soda solution has soaked into the gummy worm, tiny bubbles form on its surface when you drop it into vinegar. The bubbles grow big enough to lift the worm.
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
Science week has been very exciting so far in Class Four! This afternoon we completed two experiments, the one shown here is how to make lava lamps.
First we had to put water into a plastic bottle, next we added food colouring and vegetable oil. When we had done this we sprinkled salt into the bottle and saw the salt sink to the bottom and the bubbles rise up like a lava lamp. We did lots of research about why this happened and has great fun making them.
Keep looking on the blog this week to see what we get up to next.
Since October year 3 and 4 have spent two afternoons a week with our lovely artist Mrs Guildford. The children have developed and used a range of skills over the last few weeks to be able to create fantastic art work. The children’s work was based on the topic we have done in class which of course last term was ‘The Stone Age’.
Today Libby, Vaughan, Rory and Aly spent time with Mrs Guildford putting all of their work together in the entrance hall to make a wonderful display. Here are some of the pictures of the display, please do call in to have a look if you get a spare moment as it really is brilliant to see the hard work these children have been doing over the last few months.
Year 3 and 4 have been working together this morning to complete Christmas craft activities; they have made their own baubles, Christmas tree decorations, dress the snowman, Christmas colouring, iPad activities, laptop time, different games and even some baking. We loved the baking especially having a lick of the bowl afterwards. When we asked if we were allowed to Mrs Daley said ‘why not it’s Christmas’ 😋
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.
