2K at Lammack Primary are in full swing making their fabric sandwiches. The children are testing a variety of materials and even testing some of their own ideas to make a waterproof coat.

Ready for testing.

The children at CCM are exploring colourful shadows by building towers and shapes with the magnet tiles.

# data[].attributes.body
A created her own bird puppet and is exploring how to change the size of its shadow.

“The sun is my light source”

“The bird is blocking the sun so the shadow comes”

“If I move closer to the floor it gets bigger I think”

Year 2 at Horndon on the Hill C Of E primary school (Essex) made fabric sandwiches using newspaper, bubble wrap, PVA and wax crayons. We recorded our findings in a table.

# data[].attributes.headline
We used cotton with wax crayon as a fabric sandwich, it was waterproof and you can see the water droplets sitting on top of the fabric.

We are enjoying testing our ‘sandwiches’ to see which material is waterproof!

Marvellous marble runs in the making!

# data[].attributes.body
Peregrine Class (Co-op Academy Oakwood) testing out their initial ideas together.

# data[].attributes.body
We investigated making shadows with our hands and torches!

6B Marble runs

# data[].attributes.body
"Wait a minute, I've got an idea!" Peregrine Class (Co-op Academy Oakwood)

# data[].attributes.body
Timothy Hackworth 5T making their marble runs!

# data[].attributes.body
"What if we try this?"

# data[].attributes.body
Year 6 are working so well together to make their marble runs!

# data[].attributes.body
“We’re using the smallest possible angles to slow the marble down”.

# data[].attributes.body
“We had to start all over again as our run wasn’t working very well, but that’s ok!”

# data[].attributes.body
6B Trying different techniques to increase friction.

# data[].attributes.body
One group trying to fix the end part of the run as the marble keeps stopping before the end… great teamwork and resilience!

# data[].attributes.body
"We have added some bumps in our run to slow the marble down" Peregrine Class (Co-op Academy Oakwood)

# data[].attributes.body
"If we change this bit the marble won't fit through. Let's make it a bit wider." Peregrine Class (Co-op Acadmemy Oakwood)

# data[].attributes.body
One creative group added in a tunnel! They weren’t sure if it slowed the marble down or not though.

# data[].attributes.body
We have enjoyed making our dinosaurs “even more fiercer” by creating shadows.

We experimented making them bigger and smaller by moving further away/closer to the light source.

# data[].attributes.body
We have used our shadows to give our friends (and teachers 😂) funny faces.

We drew faces on the floor and then stood in front of the light source to give our shadow an emotion.

“I block the light source and now I’m happy” giggled C

“The sun is our light source” explained H

Adding blu-tack for some extra friction.

# data[].attributes.attachment_caption
Very proud of what they have done so far! 

# data[].attributes.body
5M are working on their marble runs. These girls have created a fantastic run which took 13.81 secs to get down. They are going to work on improving it to make it even slower!

# data[].attributes.body
We noticed that the Blu Tack we used to attach the lolly sticks slowed down the marble - so we utilised this and built it into our prototype.

# data[].attributes.body
Beginning to time and adapt out Marvellous Marble runs. "We need to try it three times to make sure we have an accurate time."

# data[].attributes.body
Red Kites‘ winning time so far. 11.8 secs

# data[].attributes.body
We are experimented with slowing down the marble by manipulating card. We tested and adapted the length of the card strip so the marble slowed without becoming stuck.

# data[].attributes.body
Bullfinch class hung their fabric sandwiches up to dry while they were out to play.

# data[].attributes.body
We used syringes to measure out the same amount of water.

# data[].attributes.body
Year 5 Richard Avenue replacing smooth surfaces with rough in an attempt to slow the marble down.

# data[].attributes.body
Making some brilliant Marble Runs in Year 6. The children are working in Teams of 2 or 3. Our best time currently is 14.93 for Cai and Seth!

# data[].attributes.body
We recorded our results in our science books.

# data[].attributes.body
Year 3 discovered if we changed the surface of the bottle it affected the distance it rolls.

# data[].attributes.body
The slowest so far...extras to be added this afternoon.

# data[].attributes.body
Some really creative marble runs from 5/6W!

# data[].attributes.body
Investigating surfaces for Dunlop was lots of fun! We explored, discussed, disagreed, repeated and reached a conclusion with a scientific explanation.

# data[].attributes.body
4M at St James worked hard testing a number of materials and drawing a conclusion from their results

# data[].attributes.body
4T at St James worked scientifically to identify the anomalies in their results

# data[].attributes.body
The children tested cooking oil, pva glue, glue stick and wax crayon!

# data[].attributes.attachment_caption
The children in 1P tested different materials for a waterproof coat.

# data[].attributes.body
The start of our investigation. We timed our marble with no obstacles so we had a "control" to compare our results against.

# data[].attributes.body
We had lots of fun exploring different materials. RTS found that the corrugated cardboard was the best material for this experiment.

# data[].attributes.body
We introduced lolly sticks and other materials to slow our marble down.

# data[].attributes.body
Using a lolly stick to manipulate card and form a surface to increase friction and slow down our marble.

# data[].attributes.body
This group tried a sandpaper base to increase the friction but it didn't really slow the marble down.

# data[].attributes.body
Wrapping a fluffy pipe cleaner around a lolly stick to create bumps as obstacles for the marble.

# data[].attributes.body
This group tried some blu-tack "speed bumps" to slow the marble down. We talked about why these are used in real life.

# data[].attributes.attachment_caption
Group 1 testing the 'control' water bottle with no materials wrapped around it.

# data[].attributes.body
The children had great fun exploring and experimenting with different materials to see which one would make the water bottle roll the furthest. It turned out that the water bottle with nothing wrapped around it travelled the furthest and the water bottle with cotton wool wrapped around it travelled the least.

The children work in groups and conducted their experiments as a team and then recorded their results in this table on the whiteboard.

# data[].attributes.attachment_caption
4G, Richard Avenue have tested different material. We have shared results as a class, and we generally agree that there was more friction with fabric or bubble wrap and less no material on.

# data[].attributes.body
Adapting and improving as we go.

# data[].attributes.body
Richard Avenue, 4G ~ We needed time to organise our investigation and think about how we would measure to gain accurate results.

# data[].attributes.body
We have worked hard to improve our design and our time.

We had loads of fun testing the different materials.

"This wasn't as long as we thought it would be!" Peregrine Class, Co-op Academy Oakwood

# data[].attributes.body
Wo

"We borrowed an idea from a pinball machine to see if we could make the marble bounce backwards and forwards for a long time."

# data[].attributes.body
Careful observations at Richard Taylor Harrogate

# data[].attributes.body
Preparing our fabric sandwiches together and making predictions . We had so much fun !

# data[].attributes.body
Working together creating g out fabric sandwiches It wa so much fun - thank you!

# data[].attributes.body
The children used straws and wooden dowels to create their marble run.

# data[].attributes.body
Year 6 managed to produce 14 working marble runs. Super team work and innovative thinking.

# data[].attributes.body
See our marvellous marble runs

Year 6 worked really well together to produce their marble runs. We had a go and then adapted or designs.
