We’ve launched into our final units in Science which are all about soil and plants.

Soil is so important for life on earth. So, what exactly is it? Soil is a combination of water, air, dead plants and animals, and rocks. We learned soil has several layers including:

• topsoil + humus
• subsoil
• bedrock

Humus is formed from decomposing or rotting things such as leaves, plants, animals.

Soil can be found on the upper layer of the earth and is sometimes known as the “skin” of the earth.  It can be a home for animals, plants, bacteria, and insects.

We’ll be learning a lot more about soil and plants in the coming weeks.

What are things you have found in soil?
