Reflection: High Quality Task Part Two - Base Line Data on the Soda Cup Lander - Section 3: Linear and Scale Measurement Experts


Rather than students learn 2 measuring methods from me, how to use a ruler and scale. I decided to split the class into 2 groups; one group would learn how to use the scale and the other group would learn how to use the centimeter side of the ruler. Less time was used with directed learning, since 2 skills were taught simultaneously and more time was spent with hands on application.

Students had more time to learn one skill well rather than rush through learning 2 skills. Experts could focus on one skill and know that their partner was learning something that they could show them later. Also through the teaching, experts become more proficient with their skills.

My students do not listen carefully to each other, by establishing expert groups students were motivated to learn their skill well enough to teach their partner. Each student had something meaningful to share with their partner, which boost the confidence of all my students..

I want students to be familiar with taking measurements of mass and length so that when they evaluate the scientific instruments in the next lesson, they will  be comfortable with using the ruler and the scale. 

Students liked the idea of becoming experts and took their job seriously. The expert groups  worked well together to organize the steps.

Part Two - Base Line Data on the Soda Cup Lander

Unit 3: Unit 3 - Deep Ocean to Rocky Shore Adaptations and Submersible Designs
Lesson 5 of 12

Objective: SWABT use a scale to find the mass and a ruler to take the linear measurements of their 'soda cup lander'.

Big Idea: Tools of the trade: students learn how to use a scale and ruler, so they can take accurate data for their Sea Cup Lander in the next lesson.

Big Idea: Before entering first grade, young children need to have a basic understanding of measurement. They do not need to be able to use standard units of measurement, but they must be able to use the basic attributes of length.
