1. To collect materials and tools, you need to prepare the following materials and tools: a ruler or tape measure, a piece of paper, a pencil and a pair of scissors.
2. Measure the length and width of the palm: Take a piece of paper and put it on a flat surface. Gently draw the outline of the palm of your hand on the paper with a pencil. Make sure your palm is on the paper so that you can draw the outline accurately. Measure the length of the palm with a ruler or tape measure, that is, the distance from the longest fingertip to the wrist. Usually, the length of the palm is the distance from the tip of the index finger to the wrist. Measure the width of the palm with a ruler or tape measure again, usually the distance from the thumb side to the little finger side.
3. Calculate the area of the palm: use the measured length and width to calculate the area of the palm. This area can be calculated by the following formula:
Area = length × width
4, in the query work, you can summarize the measurement data and calculation results.
(1), the length and width of your palm.
(2) The calculated palm area.
(3) The comparison between your own palm size and the average palm size (if you can find the corresponding data).
(4) If possible, consider the influence of gender, age, or other factors on the size of the palm.
You can state a conclusion, such as whether your palm is big or small relative to the average palm, or you can discuss what practical significance or application you think the result of this inquiry is.
What is the significance of the math inquiry homework in my palm?
1, Application of Mathematical Skills: This assignment can help students apply mathematical skills to practical situations. Measuring the size of the palm involves the calculation of length, width and area, which is the basic concept of mathematics. Through actual measurement and calculation, students can connect abstract mathematical concepts with real life.
2. Data analysis and statistics: This assignment can teach students how to collect data, analyze data and extract useful information. Students can learn how to calculate the average, standard deviation and other statistical indicators, so as to have a deeper understanding of their measurement results.
3. Scientific method: This assignment can guide students to use scientific methods for research. They need to make assumptions, design experiments, collect data, analyze the results and draw conclusions. This helps to cultivate scientific thinking and experimental skills.
