There are lots of things living in your garden and local parks or wild areas. Take part in the scavenger hunt to see what you can find. Will you be able to complete the hunt?

Our Scavenger Hunt and activity sheets ensure that the whole family can take part in the weekend fun, and have some time away from screens. Head outside to see what you can find!

This year our sheets focus on habitats. Learn about what lives On Solid Ground or In Watery Places. See how many you can find, and solve the puzzles on the back of the sheet.

Both sheets are for all ages, so you can choose which would suit you best. ‘On Solid Ground’ is designed to be a little easier, while ‘In Watery Places’ presents more of a challenge.

You can complete the Hunt or Challenges at any time, but be sure to share them with us during the month of May to be in with a chance to win a prize!
