To solve the problem of how Jack can mark off a space of 1 m² outdoors accurately for his science observations, we need to consider the different ways he might approach this task. Here’s the reasoning step-by-step:
1. Understand the Problem: Jack needs to mark off an area of exactly 1 square meter (1 m²) outdoors. This area should be well-defined so that he can consistently return to observe the same spot every day for a week.
2. Consider the Options:
- Option A suggests that Jack measures a space of 1 m x 1 m on a large sheet of paper and then uses the paper to mark the space outside.
- Other options (not mentioned in the question) might involve using a ruler, measuring tape, or other tools directly on the ground.
3. Evaluate Option A:
- By measuring a 1 m x 1 m square on a large sheet of paper, Jack can ensure that the dimensions are accurate because he can correct any errors while working on the paper surface.
- Using the sheet as a template to mark the space on the ground can help in maintaining the same dimensions accurately when transferring the measurements outdoors.
- This method minimizes potential errors that might occur if Jack were to measure directly on uneven ground, where it could be harder to ensure straight lines and right angles.
4. Conclude:
- The use of a large sheet of paper as a template provides a reliable and accurate way to ensure that the 1 m² area is correctly marked.
- This method is particularly useful for ensuring consistency and precision in defining the observation area.
Thus, based on these considerations, the most accurate method for Jack to mark off the space is:
Option A: Jack will measure a space of 1 mx 1 m on a large sheet of paper. He will then use the paper to mark the space outside.
