The Badgers were deciding how much water to add to the fabric sandwiches!

Group 3 creating their ramp

# data[].attributes.body
Step 1 - create a ramp!

# data[].attributes.body
An alternative ramp to prevent a drop at the end!

# data[].attributes.body
As an extension, we are combining materials to see if this increases friction!

# data[].attributes.body
Filling our water bottle with water to test the friction, will it travel further we wonder?

We found out bubble wrap is the best material because it created the most friction.

Year 3 testing a can of pop which has a smooth surface

# data[].attributes.body
testing the can on how far it travels

# data[].attributes.body
can wrapped around in a tissue paper

# data[].attributes.body
tissue paper can travelling less distance compared to non tissue paper wrapped can

# data[].attributes.body
We found out the smoother the surface, the further the bottle went.

There were lots of good discussions about friction when ice skating, in formula 1 and other examples.

One child talked about how when he is at Motorcross he needs grip on his tyres to make friction so he doesn’t skid and slip in the snow or rainy weather.

We tested different materials and our results show…The rougher the surface the quicker the stop time and the shorter the distance it can travel

6N had great fun making our own marble runs!

# data[].attributes.body
We gathered all our testing information and results onto a fabulous class poster

# data[].attributes.body
Year 5 are really enjoying working in teams working out how fiction affects movement by using a variety of resources

# data[].attributes.body
We found out that the rougher surfaces didn't travel as far as the smoother surfaces. We concluded that having a rougher, bumpier tyre was important to avoid it slipping. We also talked about how tyres wear down and become slippier so they need changing.

# data[].attributes.body
We did decide that if it was too rough though that wouldn't work. As we were testing, we decided that the height of the ramp wasn't enough so we changed it. We then had to go back and test all the surfaces again from our new height to make it a fair test.

Name of material

Liquid that came through (ml)

Glue stick - 3ml

Wax- 3ml

Cooking oil- 1ml

PVA Glue- A drop

We used a syringe to insert water onto the fabric. To make it a fair test, we kept the amount to 5ml. The Olive School noticed that the PVA glue let the fewest amount of liquid in!

Will netting make the bottle go quicker or slower??

# data[].attributes.body
We found that tin foil made our bottles really smooth, which made them travel further!

# data[].attributes.body
The children in Hawthorn class really enjoyed this investigation! They discussed the use of tyres on bikes, cars, F1 cars and even Velodrome bikes! #stemweekrocks!

This is how we chose to record our results.

1S at Ryders Hayes tested; foil, crayon and paper. We found that the foil was the most waterproof!

4W from Our Lady’s Corby thoroughly enjoyed the investigation today!

Year 4 at Arthur Bugler Primary School, Stanford le Hope, Essex, thoroughly enjoyed your project today. After the live session, they excitedly chose their resources and began to build ramps and find materials to cover their bottles. From smelly old soft socks to rough sheets of sandpaper. The atmosphere was electric! They tested and changed variables with great enthusiasm. Here are some photos of all the organised chaos… fabulous. Thank you.
