This morning



Square bubbles?


Setting Up




Mr Hockton and Mr Cooper have been busy making you bubble cubes

Your teachers have also made you some bubble mixture


Predictions / What do you think will happen?


  • Talk to your partner
  • What might happen if we put the cube in the bubble mixture?
  • Record your ideas as a class on the board


Let’s try

  • Dip your cube frame into your bubble mixture.  You should get a bubble on each side of the cube.
  • Gently wobble the frame and you should make some more unusual bubbles.
  • Use a straw to blow into the middle of the bubble frame - you should be able to make a square bubble.
  • Try a few times and if you are not successful watch it might help.


What could we try next?


Now that you have explored this investigation what could you do next?






PREDICTIONS - What we thought would happen


OBSERVATIONS - What we saw happening


NEXT STEPS - What we could investigate next














  • We might have liquid everywhere.
  • It will turn to lemonade.
  • It might turn into green water.
  • You are going to blow the straw and make bubbles.



  • I can see a bubble.
  • I can see a bubble. It is like a cube.
  • I can see lots of bubbles.







  • We can blow inside the cube and have more bubbles.
  • We try with different 3D shapes.


























  • The mixture will go in the cube.
  • There is going to be a cube bubble, when you blow it out it will make a square bubble.
  • It’s going to turn into a bubble square.
  • It’s going to be a bubble square.
  • Bubbles will turn into a square then you can blow it out.








  • The bottom turned into a square.
  • It popped but when we wiggled it, it went big and small.















  • You could change the shape into a circle or a rectangle.
  • You could change the shape into a triangle.























  • It might keep on popping.  
  • It will make a square bubble





  • It took a few goes until it worked.
  • It looked like a square in a square.
  • The square bubble looked like it was never going to end.




  • Try different shapes like a pyramid













  • The cube will have soapy sides
  • The soapy sides will be very colourful
  • The soapy sides will go through and down
  • The soapy sides have made a box in the middle
  • I can see many different shapes inside the cube. 
  • The sides will break easily


  • Try to work with different shapes
  • See if I could add food colouring to make the cube look different. 
  • Hold the cube up to a light to see what happens







  • It will make square bubbles.
  • It will make round bubbles.
  • They will pop.




  • The bubbles were touching and making different shapes.
  •  The bubbles got larger when we gently blow in the bubble.
  • They popped when you shake it to much.



  • We could use different 3d shapes.
  • We could make the cube larger.
  • Use coloured water.













  • When we put the cube in the bubble mixture all the parts will be full and when we blow it will make a huge bubble.
  • We will put the cube in the bubble mixture and then when we take it out maybe on the side there will be a bubble.
  • The bubbles stuck to the walls.
  • A square bubble was in the middle







  • Make the wires a different shape – maybe a triangle.
  • We could put colour in the bubbles.




















  • Round bubbles will still come out.
  • There will be square bubbles, because the bubbles are being blown out of a square-shaped blower, compared to a rounded one.
  • It will be a 3D cube, if you pull it out of the mixture because the surface of the straws are smooth, it sticks and keeps the shape.


  • Not all the sides had a bubble.
  • When we blew the bubble, the cube became bigger.
  • There were diagonal shapes created in the middle of the cube.
  • When we blew extra solution into the middle, we created a cube in the centre!
  • When we tried again, we could add more bubbles to create extra cubes!



  • We could change the shape of the polyhedron.
  • A different liquid instead of water.
  • Add colouring to the bubble mixture







































  • There will be a bubble right in the middle of the cube.
  • Lots of little bubbles will come out when we blow, I don’t think it will make a square bubble.
  • The bubbles will come out from each angle and make a large bubble which will pop straight away. 
  • There will be a bubble in the centre.













  • The bubbles were flat surfaces on each side but there was a square shape in the middle.
  • It made a good illusion like it was transparent in the middle.
  • Our bubbles popped easily and quickly because we didn’t have any glycerine. 
















  • We could see how big we could make the cube to see if we can get an even bigger square bubble.
  • We could try using a triangular prism or a square based pyramid to see what shapes this would create.
  • We could try using different washing up liquids to see if that makes a difference.
  • We could try mixing the washing up liquid with sparkling water to see if it creates more bubbles.
  • We could try using hot water instead of cold water to see if that makes a difference.
  • I think using hot water would make it more jiggly.
  • We could use different ‘soaps’ like hand wash or shampoo. 















  • I think it will make a bubble inside the cube.
  • I think the bubbles will be cube shaped.
  • The bubble might pop when we try and take it out of the cube.
  • I think the faces of the cubes will become soapy and bubble up.
  • The bubbles will be sperical.




  • The bubble pulled away from the faces on the cube and created a small bubble cube. 
  • The bubbles were sticking to the straw because it was a clean surface.
  • The cube frame helped to create straight line bubbles.
  • The faces were square and made bubbles so when air blows onto it it pushed the mixture onto the middle.
  • Try different 3D shapes such as pyraminds, cylinders and cones.
  • Instead of washing up liquid try it using bubble bath.
  • Put double the amount of washing up liquid in the bubble mixture.
  • Try to make the bubbles without the glycerin.
  • Make the frame from a different material such as wood.
