Your garden is a great place to look for all sorts of bugs - try searching under rocks and stones, in the soil or the grass. Does your critter have fur, wings or many legs?
No.32 find some frogspawn
Large jelly-like clumps of frogspawn with little black dots in the centre seem to magically appear in ponds in the spring. Can you find some?
No.33 catch a falling leaf
It sounds like one of the easier challenges, but catching a falling leaf can be tricky - all you need is a little gust of wind and off your leaf goes, spiralling away from your hand. If you can do it though you'll have ticked off another of the activities on the list!
No.34 track wild animals
You can track footprints, feathers fur or even animal poo to try and find a wild animal. Mud is one of the best places to spot footprints or poo, but remember that all animal footprints are different depending on the animal, so you may need to learn what some common ones look like. Of course, you could try and track smaller crawlies like worms by looking out for piles of soil that they make too. Keep your eyes peeled whatever you're tracking!
No.35 discover what's in a pond
Pond water is full of life. If you scoop some out into a container with the same temperature water (that's important!) then you can find all sorts of weird creatures, plants and things. Don't forget to put everything back in the pond afterwards though. The pond creatures will also be happier if you can keep them out of the sun while you're investigating!
No.36 make a home for a wild animal
All sorts of animals need homes, so why not try making a bug hotel, a house for a hedgehog, or even a motel for a mouse. Think about the creature you're making a home for - does it need to be warm, light, dry, dark, cold, or wet?
No.37 check out the crazy creatures in a rockpool
Challenge your family to see who can spot the most unusual rockpool creatures. Try to get to the beach for low tide as it’s the best time to look for sea creatures such as sea anemone, hermit and shore crabs or even the hard to find porcelain crabs – but be careful, they’re fragile.
No.38 bring up a butterfly
From a caterpillar, to a chrysalis and then a butterfly, the life cycle of a butterfly is amazing. Be careful what type of caterpillar you choose to look after though, because some can take up to a year to turn into butterflies!
No.39 catch a crab
To become a champion crabber you’ll need a net, some bait and a bucket of water. See if you can catch the most commonly found variety known as the shore crab, or try and spot the more elusive spider crab. Just remember to put anything you catch back where you found it afterwards. Crabs have busy lives too, you know.
No.40 go on a nature walk at night
If you can stay awake when it's dark then it's the perfect time to spot (and listen to) creatures that only come out at night. Take a torch but only use it if you really need to as animals can see much better than you in the dark. Soon you'll be spotting and hearing hedgehogs and all sorts of things that like the night time better than the day.
