Step-by-step solution for: Worksheet - Observations, Inferences, Classification (Editable) worksheets library
To solve the problem, we need to determine whether each statement is an observation or an inference, and provide a reason for our choice. Let's go through each statement step by step:
---
- Observation: This is something that can be directly seen or felt. You can physically observe the sharpness of the corners.
- Reason: Can see and feel the sharp corners.
---
- Observation: This is a direct measurement or visual assessment that can be made by comparing the dimensions of the object.
- Reason: Can see or measure this.
---
- Inference: While you might observe the object as solid, determining what specific substance it is (e.g., rock, metal, plastic) requires additional information or reasoning beyond direct observation.
- Reason: Did not see how it was formed or know what it is made of.
---
- Observation: This is something that can be directly observed by looking at the object.
- Reason: Can see and feel flat sides.
---
- Inference: Observing the color change alone does not tell us the cause (weathering). Determining the cause requires reasoning beyond direct observation.
- Reason: Did not see the weathering process.
---
- Observation: This is something that can be directly seen when examining the rock.
- Reason: Can see the layers.
---
- Observation: This is something that can be directly observed by examining the rock closely (e.g., with a magnifying glass).
- Reason: Can see the size and color of the crystals.
---
- Inference: This statement involves reasoning about the history of the rock, which cannot be directly observed. It requires knowledge of geological processes and time scales.
- Reason: Could not have been there when it formed.
---
- Observation: This is a direct test where you can observe the result of scratching the glass.
- Reason: Can see the scratch in the glass.
---
- Observation: This is a direct measurement using a scale, which is an observable fact.
- Reason: Measurements are forms of observations.
---
- Inference: Observing the footprints alone does not definitively tell us what animal made them. Inferring that they were made by a dog requires reasoning based on the shape and size of the footprints.
- Reason: Unless you saw the dog make the prints, you can't be sure it wasn't a different animal.
---
- Observation: This is something that can be directly counted and seen.
- Reason: You can count the footprints.
---
Here is the completed table with observations and inferences:
| Statement | Observation / Inference | Reason |
|---------------------------------------------------------------------------|--------------------------|---------------------------------------------|
| 1. The object has sharp corners. | Observation | Can see and feel the sharp corners. |
| 2. The object is longer than it is wide. | Observation | Can see or measure this. |
| 3. The object is made of a solid, occurring substance. | Inference | Did not see how it was formed or know what it is made of. |
| 4. The object has flat sides. | Observation | Can see and feel flat sides. |
| 5. The rock has changed color due to weathering. | Inference | Did not see the weathering process. |
| 6. The rock has thin, distinct layers. | Observation | Can see the layers. |
| 7. The rock is made of small, dark-colored crystals. | Observation | Can see the size and color of the crystals. |
| 8. The rock did not exist 100 million years ago. | Inference | Could not have been there when it formed. |
| 9. The rock scratches a glass plate. | Observation | Can see the scratch in the glass. |
| 10. The rock's mass is 254 grams. | Observation | Measurements are forms of observations. |
| 11. The footprints were made by a dog. | Inference | Unless you saw the dog make the prints, you can't be sure it wasn't a different animal. |
| 12. There are five footprints in the mud. | Observation | You can count the footprints. |
