Fun and interactive worksheet designed to teach students how to identify organic materials suitable for composting while reinforcing vocabulary related to fruits and vegetables.

Let's solve the Compost Activity Sheet step by step.

Part 1: Circle the items that are organic and can be composted

We need to identify which of the listed items are organic (originating from plants or animals) and compostable (can break down naturally in a compost pile).

Here is the list with explanations:

| Item | Compostable? | Reason |
|--------------------|--------------|--------|
| styrofoam cup | ✘ No | Plastic-based, synthetic, does not decompose |
| newspaper | ✔ Yes | Paper, biodegradable (especially if ink is soy-based) |
| grass clippings | ✔ Yes | Organic plant material |
| peaches | ✔ Yes | Fruit – organic waste |
| plastic bag | ✘ No | Synthetic plastic, non-biodegradable |
| orange peel | ✔ Yes | Fruit peel – compostable |
| twigs | ✔ Yes | Wood from plants, breaks down slowly |
| notebook | ✘ No | Contains paper, but binding and glue may hinder composting; generally not recommended |
| computer | ✘ No | Electronic waste – contains metals and plastics |
| crayon | ✘ No | Made of wax and petroleum products |
| banana peel | ✔ Yes | Fruit peel – great for compost |
| pine needles | ✔ Yes | Organic, though acidic; composts slowly |
| glass bottle | ✘ No | Inert, non-organic, doesn’t decompose |
| celery stalks | ✔ Yes | Vegetable matter |
| avocado peel | ✔ Yes | Fruit peel – compostable |
| television | ✘ No | Electronic waste |
| adhesive tape | ✘ No | Plastic/chemical adhesive, not biodegradable |
| aluminum can | ✘ No | Metal, not organic |
| leaves | ✔ Yes | Plant material, common compost ingredient |
| tree branch | ✔ Yes | Wood from trees, composts slowly |
| lettuce | ✔ Yes | Vegetable waste |
| paper clip | ✘ No | Metal |
| tangerine peel | ✔ Yes | Citrus peel – compostable |
| envelope | ⚠️ Maybe | Paper-based, but may have plastic lining or glue – better to avoid |

✔ Items to circle (compostable):
- newspaper
- grass clippings
- peaches
- orange peel
- twigs
- banana peel
- pine needles
- celery stalks
- avocado peel
- leaves
- tree branch
- lettuce
- tangerine peel

> Note: Envelope is questionable — if it’s plain paper, it might compost, but many have plastic coatings. Best to avoid unless confirmed.

Part 2: Write an item that can be compostable for each letter in "Compost"

Use the word C O M P O S T, and find one compostable item starting with each letter.

We already have:
- C → Carrot stalk (given)

Now fill in the rest:

| Letter | Compostable Item Example |
|--------|--------------------------|
| O | Orange peel |
| M | Mushroom (or maple leaves) |
| P | Pine needles |
| O | Onion skin |
| S | Straw |
| T | Tea bags (if no plastic) |

✔ Answers:
- O: Orange peel
- M: Mushroom
- P: Pine needles
- O: Onion skin
- S: Straw
- T: Tea bag

> Tip: Use food scraps or plant materials. Avoid items like meat, dairy, or pet waste.
