HANDS ON
Parts and Pieces

Like these.

Observe some small living things and identify the parts that work together to form the system that allows the living things to survive.
Materials
White paper plates
Magnifying glass
Mealworms
Mushrooms
Small onions (with roots)
Carrots (with leaves)

Procedure
Look closely at the mushrooms. Identify the parts and pieces of the mushroom.
Look closely at the onion and carrot. Identify the roots and the "leaves" on each. Compare which parts are edible.

Carrots Onions

Look closely at the mealworms. Identify the parts. Try to observe what each part does.

Conclusions
All of the objects you observed are living things. Yet, each has different parts that have different functions.
Which had the most parts? Biggest parts? Smallest parts?

Extension Ideas
You may or may not decide to "dissect" these living things according to your own school's practice.
Consider which parts are essential and which are non- essential for each living thing to survive.
