Accidental discoveries


telephoneDesigned to be used either as printed worksheets or as an interactive PDF on a whiteboard, activities in this pack are intended to act as a stimulus for your own National Science & Engineering Week activities and three are accompanied by video demonstrations, which can be viewed by streaming them from the internet - the links to these are within the PDF.

The activities are aimed at 5-11 year olds but may be suitable for a range of age-groups and can be tailored to the ability of the group.

  • The ‘Accidental discoveries’ activities have all been designed for use in discrete 20–60 minute class or science club sessions.
  • Activities 1-12 are short, fun experiments that can be done as filler activities or a range of round-robin sessions. They use resources that can be sourced cheaply and easily.
  • Successful completion of each of activities 14 and 15 can count towards a CREST Star Investigators award.
  • Extra suggestions are also given for each activity for older or more advanced children.
