Science Class

In science class we have been learning about ecosystems, ecosystem means a place where there are biotic and abiotic things. Biotic are living things and abiotic are non-living things.

Some of the girls in our class made little cards with words on them. The words were ecosystem, biotic, abiotic, ecological seccession, micro-organism, biosphere, photosynthesis, scavengers, bioaccumulation and decomposer. Each person in our class got two words, then you had to find the people with that word. Then your group had to define the word on the card. My groups words were biotic which means living things and photosynthesis which is a process that converts carbon dioxide organic compounds,especially sugars, using the energy from sunlight. Others had words like scavengers which means thing eating other thing and biosphere which means the part of the earth’s crust, the part that supports life. Decomposer is a person or thing that rots or decomposes or micro-organism which is any organism too small to be viewed by the unaided eye, as bacteria, protozoa, and some fungi and algae.

Another thing we did in science was, we went on a walk around some parts of Snow Lake. We looked at different ecosystems like the forests or things like someones front yard. Mr. Fisher showed us examples of bioaccumulation in action. Bioaccumulation are things that are toxic substances occurring in the environment. People took cameras to take pictures of ecosystems and other things in a ecosystem. He also showed us examples of ecological succession, like trails that no one uses anymore, plants are growing back.

    It is always great to get outside and walk around, looking around in our own community to see what kinds of things we can see and find. How long do you think it would take for a community to grow over? Talk about ecological succession in action. Have you ever been over to Herb Town (an abandoned mining town form the 1920s – 40s close to Snow Lake) and taken a look at what is left? It’s actually quite interesting.
