This activity is all about measuring circumferences. Children will go outside and find 8 trees to measure the circumference of, recording their answers in the table. It's good to discuss what the easiest way to measure the circumference of a tree trunk is, hopefully coming to the conclusion that using string is a quick and easy way to measure the circumference. You can either mark out length of string or get them to measure the string after each trunk measurement.
Once they've recorded the circumference of 8 tree trunks they can then complete the differentiated question sheets. The second sheet has a focus on averages whereas the first sheet focuses on simple questions about the data they've collected.
We think you'll also love our Carbon In Trees Investigation where students will use formulas to figure out the amount of carbon stored in trees.
