Icecream is a dessert made from frozen milk or cream. Icecream is usually flavoured with sugar, vanilla, fruit or chocolate. Icecream is made by freezing the milk or cream slowly and stirring it frequently so it stays smooth. If you don't stir it, it will be full of crunchy ice crystals and will not be as nice. Icecream is sometimes served in a cone.

Insects are a very common group of creatures, found all over the world except the sea. Insects all have six legs and antennae on their heads to help them find their way around. Many insects have wings. Insects lay eggs and many start life as a worm-shaped larval stage before growing up into the adult form that you see everywhere. The larval stage of the butterfly, the caterpillar, is the most well-known.
