Reading Graduated Cylinders
Est. Class Sessions: 1Summarizing the Lesson
When all students have recorded data for each of the cylinders, ask different pairs of students to report their results to the class.
In particular, ask:
Show the display of the data table from the Reading Graduated Cylinders pages again. Call on volunteer pairs to fill in the column labeled Agreed Reading. Ask the other students to compare the readings written on the display with their own readings. Encourage them to ask questions if they notice discrepancies. If significant numbers of students disagree on the reading for a particular graduated cylinder, ask students to reread the water level in that cylinder and discuss possible reasons for the different readings.
Tell students to make sure the numbers in the Agreed Reading column on their data tables match those on the display. Students should change any Agreed Readings that don't match the display, as they will be used in Check-In: Question 2 on the Reading Graduated Cylinders pages.
When all Agreed Readings have been determined, ask students to answer Check-In: Question 2 and then ask:
Provide time for students to complete Check-In: Questions 2–5.
