Stone Age Art

This week we went to the forest to explore how Cave paintings were created. We made our own paint brushes with sticks, feathers, moss and leaves. We also made different coloured paints from nature: charcoal, chalk, crushed leaves and mud. We used modern methods to recreate; Cueva de las Manos – The Cave of Hands (Argentina) . It is fascinating to think about how long ago some of these images were created and consider what they tell us about the Stone Age times.

Science week Market Place

Yesterday to celebrate our Science week we invited parents in for our ‘Science Market Place’ so that we could share all of the work we have completed throughout the week. It was a great opportunity for the children to showcase their work and set up stalls with investigations for everybody to enjoy. There was even a competition between Year 5 and Year 6 on the go as they had designed and made a brand new chocolate bar for Cadbury’s World. Parents had the opportunity to vote on the appearance, texture and taste. It was a tough choice as they were both delicious but Honeycomb Heaven won meaning Year 5 took the overall prize!! Well done to both classes for their entries.

The children have had a brilliant week and learnt lots along the way. Thank you to everybody for making Science Week a huge success.

There has been a poster and habitat competition on the go and we have had lots of fantastic entries, the winners will be revealed next week.

How strong is chocolate?

In year 3 this afternoon we have tested how strong different chocolate bars are using a variety of investigations. We dropped the chocolate, snapped the chocolate, out weights on the chocolate and then finally hit it with a hammer. We found that the dairy milk was the strongest. Unfortunately we were unable to eat the chocolate – we were not impressed!

Robot workshop

To kickstart our super science week we had a robot workshop this morning. It was great fun but also quite tricky. We worked in groups of 3 to build a robot that would be able to move when programmed. We were given a box per group and had to use problem solving skills to find the best way to build it.

Baking volcano cakes

This week we have been very lucky and had Mrs Barnes with us for baking. We made volcano cakes by baking cupcakes and tipping them  upside down and cutting out a piece of the cake. We then used orange and red icing to create the effect of lava flowing out of the volcano.

 

To celebrate our last day with Mrs Barnes as it’s been our week of baking we made ‘cake pops’ to link with the chocolate from Cadbury’s world and decorated them with red icing to give the effect of volcanoes to link to our topic. We had great fun and they tasted delicious.

 

Volcanic eruption

On the last day of baking with Mrs Barnes instead of making biscuits we used our skills to create a 3D volcano, we used a coke bottle, tin foil, various colours of fondant and mentos.

We created two volcanoes and took them outside, we added the mentos and saw the reaction that was created.

Why does the explosion happen?

Although there are a few different theories around about how this experiment works, the most favoured reason is because of the combination of carbon dioxide in the Diet Coke and the little dimples found on Mentos candy pieces.

The thing that makes soda drinks bubbly is the carbon dioxide that is pumped in when they bottle the drink at the factory. It doesn’t get released from the liquid until you pour it into a glass and drink it, some also gets released when you open the lid. This means that there is a whole lot of carbon dioxide gas just waiting to escape the liquid in the form of bubbles.

Unfortunately our explosion didn’t beat the record of 9 metres but we still had fun.

Edible rocks – Science

In Science to understand the formation of rocks we put our culinary skills to the test.

To show sedimentary rock we needed to show that they are formed from deposits settling at the bottom of the seas, lakes and rivers. We showed the water bed by using blue fondant icing, coloured sprinkles to represent fossilized bones and other layers of icing and chocolate to show the layers and sediment that build up over the years.

To show metamorphic rock we needed to show that these rocks have been changed by heat and pressure. For this we used three different colours of icing, layered the different coloured icing and folded them together. Once the rocks had been made we cut them in half to see the different swirls and layers.

To show igneous rocks we needed to show that they are formed when melted rock or magma is cooled. The children mixed up mini marshmallows, broken up biscuits and chocolate drops. We did this until the chocolate had melted and then we left the mixture until it had solidified again.

The children had great fun and ate their rocks at the end of the lesson.

Volcano biscuits

This half term to link with our topic ‘Shake, Rattle and Roll’ we made volcano shaped biscuits with Mrs Barnes. We made chocolate cookies first and then decorated them with fondant. This was good fun and we practiced lots of skills too including; reading, weighing, mixing, rolling and of course all important team work.
