LO: To Investigate the effects of friction on different surfaces.
Following on from our jelly investigation last week, we are planning to conduct a whole class investigation using Microsoft Teams.
This will allow us to introduce the investigation and carry it out as a class. If you can’t join us for the meeting, then there is an investigation below that the children can complete if you have the time and resources.
There will a PP to follow like normal (see class page) but if you child does attend the live then they can hear Mr Boffey go through it and develop it further for them.
If you wish to conduct a further investigation at home after the Team meeting then you will need:
- A book, tray, placemat or similar (to use as a ramp)
- A snack bar or similar e.g a penguin bar
- Aluminium foil
- Bubble wrap
- Any other material which you can wrap around the snack bar etc.
Instructions for at home investigation.
- Place the snack bar on the flat ramp and slowly raise the ramp at one end to observe when it begins to slide. How high did it go? Perhaps you could get someone at home to measure the height of the ramp?
- Wrap the snack bar in a different material and repeat step 1 and observe/discuss any variation.
- Repeat step with other materials and observe. Finally, you can unwrap your snack and discover how must friction the chocolate creates
Don’t worry if you don’t have time to conduct the investigation as what we do in the lesson is fine. Below is a link where you can watch and discuss a similar investigation with your child.
Pause clip halfway and discuss with children what they think will happen. Watch to the end and discuss their predictions.
If you wish, you can record your results on the sheet below.
