This worksheet combines a student activity with a take-home guide for parents about composting basics.

Problem Description:

The task involves identifying and gluing the correct items that belong in a compost pile. The image provides a flap to open, revealing what lives in the compost pile, and asks for the correct items to be glued onto the compost pile.

Solution Explanation:

#### Step 1: Understand the Composting Basics
Composting is the process of breaking down organic matter into nutrient-rich soil. It requires a balance of "greens" (nitrogen-rich materials) and "browns" (carbon-rich materials).

- Greens are rich in nitrogen and provide energy for the microorganisms that break down the compost. Examples include:
- Fruit and vegetable scraps
- Coffee grounds
- Grass clippings
- Plant trimmings
- Eggshells

- Browns are rich in carbon and provide structure and fiber. Examples include:
- Dry leaves
- Wood chips
- Straw
- Shredded paper
- Twigs

#### Step 2: Identify the Correct Items
From the provided list of items, we need to determine which ones are suitable for composting. These items should either be greens or browns.

#### Step 3: List of Suitable Items
Based on the description, the following items are appropriate for composting:
1. Fruit and vegetable scraps
2. Coffee grounds
3. Grass clippings
4. Plant trimmings
5. Eggshells
6. Dry leaves
7. Wood chips
8. Straw
9. Shredded paper
10. Twigs

#### Step 4: Exclude Unsuitable Items
Items that are not suitable for composting include:
- Plastic bags: Non-biodegradable.
- Metal objects: Do not decompose.
- Glass: Does not decompose.
- Meat and dairy products: Can attract pests and create odors.
- Pet waste: May contain harmful pathogens.

#### Step 5: Glue the Correct Items
The task requires gluing the correct items onto the compost pile. Based on the list above, the correct items to glue are:
- Fruit and vegetable scraps
- Coffee grounds
- Grass clippings
- Plant trimmings
- Eggshells
- Dry leaves
- Wood chips
- Straw
- Shredded paper
- Twigs

Final Answer:

The correct items to glue onto the compost pile are:
- Fruit and vegetable scraps
- Coffee grounds
- Grass clippings
- Plant trimmings
- Eggshells
- Dry leaves
- Wood chips
- Straw
- Shredded paper
- Twigs
