Food Chains

Food Chains

There are three major roles in a food chain:

producer- produces its own food
consumer- consumer eats another organism
decomposer- causes organisms to decay


PLAY this food chain game

Activity:

In your journal record a food chain that happens in your back yard. (must include atleast three organisms)

Ecosystems

What is an ecosystem?

An ecosystem is a community of living organisms (plants, and animals)  with the nonliving components of their environment (things like air, water and mineral soil), interacting as a system.

Activity

Look at the map below and find where in America Virginia is.
Use the key below the map and find out what ecosystem we have in Virginia.

Mass Metric System

Mass in the metirc system is measured in grams.

You will need to know the difference in size for Kilograms, Grams, and Milligrams

Watch this video on Mass

Measurement

We are going to learn about three different types of measurement.

Length

Mass

Volume (capacity)

We will use two different systems of measurement to collect our  data

Can you make a prediction of a few conductors and insulators around your house?
What do they have in common that made you think they would work as conductors?
