Squashed Tomato Challenge - Welsh

A STEM Challenge where pupils design and build a model to move tomatoes down a mountain

A fun hands on investigation suitable for pupils aged 7-19

Challenge your students to take on a real -world problem affecting people in Nepal.

The problem: In Nepal many farmers living on the mountainside grow fruit and vegetables, including tomatoes. To earn a living they need to sell these at the local market.  The problem is getting to market involves a long, dangerous walk down the mountain side and over a river, at the end of which the tomatoes may well be a bit squashed.

The challenge: To design, build and test a way of moving tomatoes that won't squash them!

The activity is accredited by the British Science Association as suitable to count towards a CREST SuperStar Discovery, Bronze or Silver Award . For more information about the scheme please go to the CREST area of our website

The challenge can provide a focus for British Science Week ; be used as a STEM or science club activity; enhance a lesson on forces/friction/levers;  form the basis of an enrichment day;  provide an activity for SEAL and PLTS and be the starting point for a range of cross-curricular activities. To view examples of how schools have used the Squashed Tomato Challenge go to Challenges in Schools.
