The 8th grade Science team at New Braunfels Middle School guides their students through a tech-infused PBL unit where students learn to model the structure of elements. The driving question of this unit is: As scientists, how can we design and create a model of an element so that these models can be used by other students in a lab scavenger hunt? Students began the unit with a pre-assessment. The score received on the pre-assessment then places each student on their individual level: Level 1-Emerging, Level-2-Proficient, or Level 3-Advanced. In each level, students are given activities and checkpoints to facilitate their own learning.
In level 1 students scan QR codes to access a video or reading passage on the Bohr Model. Students check for understanding by completing a checkpoint on the Bohr Model that they retrieve from iTunes U and turn into eBackpack.
In level 2 students scan a QR code to watch a video on element identification and then complete a checkpoint using eBackpack Assessments.
If students are not mastering the level 1 or 2 checkpoints they are pulled into small group workshops where the teacher reteaches each concept until individual student mastery is achieved.
In level 3 students demonstrate mastery of content by creating a study aid and an Element Identity Quiz. Students created their study aids using one of the following apps: Trading Cards, Quizlet, Popplet, Prezi, Tiny Cards, or Study Blue. Students created their quiz using one of these apps: Quizizz, Kahoot, Quizalize, Notability, Google Docs, or Google Forms.
For the project culmination students were to create a model of an element that could be used in a lab scavenger hunt. Students could choose to create a tangible model or a digital model using the app 123D Design. Students practice identifying each others element models during a lab scavenger hunt.
