Metric Mania Boot Camp (Day 2 of 2)
Lesson 2 of 4
Objective: SWBAT accurately measure the data at each laboratory station and convert their measurements using the metric system.
This lesson is a follow-up to the lesson: Metric Mania Field Trip.
Upon entering the classroom students will pick up their copy of the Metric Measurement Lab for today's Metric Measurement Bootcamp Activity. Students will also get out their Bell Question Sheet to record their response to today's anticipatory activity.
In the spirit of friendly competition, the students are issued a challenge to see if they can stump their partner with a metric conversion problem! Let's Get Ready To Rumble!!!
As their warm up activity, students will use their prior practice metric conversion worksheets as a sample and write three metric conversion problems. Students must write their questions at three different levels of difficulty:
- simple review (easy)
- you better have been paying attention (medium)
- wishing you the best of luck in solving this one (difficult).
The catch is that each creator of the questions, must also be able to write out the correct solution to the three questions on a separate sheet of paper. In an effort to master the content, students can only write questions that they know how to answer. By differentiating their questions, students are identifying which conversions are simple and which ones are more complex. This reflective exercise will reinforce the students mastery of this skill.
If the students can stump their partners, they will earn five points extra credit!
In yesterday's lesson, students had the opportunity to review the Rules for Metric Measurement and practice the process necessary to covert between units of measurements. Students will use these prior experiences to guide them in this fast-paced Metric Measurement Lab.
Students will rotate around the room visiting each of the lab stations. Each lab station will require the lab partners to measure the length, volume, mass, or temperature of the provided sample. Students must work collaboratively and ensure that they visit each lab station. Both lab partners must participate and provided their own individual data to each other so the pair can calculate the average measurement for each required station. Students need to be reminded to record their partner's measurements as well on their data table. Students only have 40 minutes to visit each of the lab stations and will need constant encouragement to keep on task, remain efficient, and stay focused!
As the students move around the room, the teacher will also rotate among the groups providing support and spot-checking for correct measurement techniques. Students will be asked to refer to their lecture notes that describes the correct measurement technique for each type of measurement - mass, volume, length.
The fast pace and mental fatigue the students will experience throughout this data-collection activity is reminiscent of Boot Camp. Students will be reminded that like Boot Camp, the metric system and data analysis requires constant practice in order to master the highly technical skill.
Now that each lab group has completed the required measurements at each lab station, they are ready to return to their seats and independently finish the final calculations.
Students need to analyze the data recorded on their data tables by calculating the average measurement for each of the objects at the lab stations. Remind students that to calculate the average for each measurement, they will need to add up their measurement and their partner's measurement and divide by two. Once the average measurement has been calculated and recorded on their data sheet, students will follow the prompts to convert between the units of measurements.
Students will not have enough time to complete all of the necessary conversions and accompanying questions in class, so the remaining work from the Metric Measurement Lab Worksheet will be assigned as homework.
As a review of today's lesson, students will be asked to share their average measurements for each type of measurement. There will be three pairs of volunteers to share their data for each station and the class will discuss why there is or is not a big difference in the measurements between the groups.
For Example: Group #1 states their average width of a floor tile was 30.2cm, Group #2 states their measurement for the floor tile was 22.9cm, and Group #3 measures 30.5cm. The class would discuss possible reasons why Group #2's measurements were off, review the correct method to measure length, and how to avoid this laboratory error in the future.
Throughout the class discussion, an emphasis will be placed on the need to collect accurate lab data in each and every laboratory activity to ensure an appropriate conclusions can be made. Today's lesson will help provide practice and support for the data collection skills of our budding Biologists.
