Part 1: Classify Observations (Quantitative vs. Qualitative)

#### Instructions:
- Quantitative Observations: These are observations that involve numerical data or measurements.
- Qualitative Observations: These are observations that describe qualities or characteristics without numerical data.

#### Statements:
1. Most horses measure about nine feet long.
2. The sky is blue.
3. There were 14 ducks in the flock.
4. Rocky the squirrel weighed about 43 grams.
5. Mrs. Donohue loves horses and dogs.
6. There are 20 students in 5C.
7. There are girls and boys in 5C and 5D.
8. Rocky didn’t have any fur.
9. It has been more than 100 degrees outside lately.
10. Oakbrook Elementary has nearly 600 students this year.

#### Classification:

1. Most horses measure about nine feet long.
- Quantitative: Involves a numerical measurement (nine feet).
- Answer: Quantitative

2. The sky is blue.
- Qualitative: Describes a quality (color) without numerical data.
- Answer: Qualitative

3. There were 14 ducks in the flock.
- Quantitative: Involves a numerical count (14 ducks).

12. The horses in the picture are pretty.

#### Classification:

11. There are two horses here.
- Quantitative: Involves a numerical count (two horses).
- Answer: Quantitative

Part 3: Observations or Inferences?

#### Instructions:
- Observation: A statement based on direct sensory evidence (what you see, hear, etc.).
- Inference: A conclusion drawn from observations, often involving interpretation or reasoning.

#### Images and Statements:

##### Image 1: Woman with a cat
1. I think the woman is a vet.
- Inference: Based on context (she might be a vet, but it’s not directly observable).
- Answer: I

2. The girl is holding a cat.
- Observation: Directly observable.
- Answer: O

3. The cat is very sick.
- Inference: Based on observation (the cat’s condition is inferred, not directly stated).
- Answer: I

4. The woman likes cats.
- Inference: Based on context (her interaction with the cat suggests she likes cats).
- Answer: I

##### Image 2: Children with backpacks
1. The children are wearing backpacks.
- Observation: Directly observable.
- Answer: O

2. They’re at camp.
- Inference: Based on context (wearing backpacks might suggest they are at camp).
- Answer: I

3. I see 3 hats.
- Observation: Directly observable.
- Answer: O

##### Image 3: Kids playing chess
1. I think these kids are brother and sister.
- Inference: Based on context (their relationship is inferred, not directly observable).
- Answer: I

2. They’re playing chess.
- Observation: Directly observable.
- Answer: O

3. The girl’s winning because she’s smiling.
- Inference: Based on context (smiling does not necessarily mean she is winning).
- Answer: I
