Seedling Growth and Measurement

In this video tutorial, students learn to observe and record the growth of seedlings over several days. They measure plant heights, record data, and analyze it using a line plot. The lesson emphasizes understanding plant growth patterns and making predictions about future growth. Students are encouraged to engage with the material by filling in charts and making connections between data points.
