Sound work in Science in Year 4

Today we have been learning about sound: how it is made and how it travels.

Today we designed and carried out an experiment to find out which material made the egg shaker silent with the least number of layers.

Here are our wrapped up egg shakers. 

Can you tell the materials we used?

We used (top row l-r) brown paper, fabric (socks), tin foil; (front row l-r) paper towels, tissue paper and bubble wrap.

Many people predicted the tin foil would have the least layers because you can wrap it really tight and it doesn't have holes in. But actually it made the metal egg shaker just as loud. Our experiment showed that the brown paper had the least number of layers - 7 - and we thought perhaps that is why is is used for wrapping items to post.

Everyone enjoyed this experiment and we are going to explore pitch next week in science.

Fireworks in Year 4

In Year 4, we have been reading the novel The Firework Maker's Daughter.

As it was the last day of term, we had special permission to show the children some indoor fireworks - outside.  It was very sunny as you can see in the picture, but we thought Snakes Alive was the best one. There was also Disco Inferno, Sizzling Strobes, Flash Harry and Blazing Bengals.  None of them made a noise - they all made light or sparks.  There was a lot of smoke with some of them, so it was good we were outside.

Have you ever seen Indoor Fireworks?
Did you like them?

Test on Volcanic Eruptions By CA

Today Class 6C did an experiment about volcanoes in our playground, so that we wouldn't cause too much mess in the classroom!

So we took a bottle of Coke and some polos. Then we set everything up, making sure we had a bucket of water for afterwards.

We used the bottle to represent the crust. The liquid coke we used to represent the magma. 

Then we all went a safe distance away from the experiment and our teacher dropped in the polos to create the eruption.

The experiment ended up being successful, although I think next time we would add something so we could drop in the polos quicker, as you can see from the video how we didn't get it in quick enough.

Science Week in Reception

Last week was Science week!  In Reception we did lots of exploring and discovering.

We looked at what happened to water when we put it in the freezer and then once it was frozen, we thought about how to get the objects out.  We then discovered that when the ice warmed up, it turned back into water!

We also made bubbles and used different shaped objects to blow them - but the bubbles were still round!

Finally, we made a balloon rocket!  We used the materials pictured and we talked about what makes the balloon move.  Try it yourself!

Reception loved being scientists! Well done!

Y2 Experiment with GERMS!!!

We had a Science day this week to finish up our topic of Animals including Humans. Over the last term we have been learning all about the life cycles of different animals and we finished our topic by talking about humans and how to be fit and healthy. We asked questions that we wanted to find the answers to during our Science day, we made predictions then we did an experiment. We wanted to find out how you could get germs and the best way to get rid of germs so that we could make sure we are super healthy! After that, we wrote about what we found out.  We found out that warm, soapy water cleans away and kills the most germs! So make sure when you sneeze, cough or have been to the toilet, you use warm soapy water to kill those germs!!!

Year 6 Experiments

In Science, we have been learning about the heart, how it works and how to take our pulse. A few days ago, we created our own experiments to find out if exercise has an impact on our heart rates. Today we tested our theories, which included the question 'which type of exercise increase our heart rate the most?'. We found out that, overall, our results reflected our predictions!

Here are some pictures of us experimenting on the lower playground.

Y4H Science!

This week in science, we have been investigating states of matter. We experimented with ice cubes, to see which ice cube would melt the quickest, in different temperatures of water. 

We finished up with a fun game - who could melt their ice cube the quickest! There were many different approaches to this game, some people were rubbing it between their hands, others decided to suck the ice cube, others were blowing their hot breath on it! It was very amusing to watch and great fun to do, even if it did make us cold and flood all of the tables! 😂
