STEM Labs are designed to be supplemental education experiences that are flexible and can be implemented in many different ways. Use the Pacing Guide to help make the Grabber STEM Lab fit into your schedule. This STEM Lab can be adapted for a 30-, 40-, 60-, and 55-minute implementation instead of the full 100 minutes included in the materials.
Options for implementing this STEM Lab include:
If you have a limited amount of time, only complete the Seek and Play sections. The total time for both sections is 55 minutes. The students will finish with experiences in both building and exploring Scissor Linkage designs.
An option for 60 minutes is to have a Grabber (or two) ready before class and have your students complete the Play and Rethink sections. This option compromises the initial building of the Grabber but maximizes gaining experience with the application of scissor linkages and with enhancing the Grabber's design.
An option for 40 minutes is to have at least one Grabber ready and have your students complete the Play and Apply sections. Students will gain experience with scissor linkages, while also having a sense of the context and value in learning how linkages and scissor lifts are used in other aspects of daily life.
If you have only 30 minutes and can have at least one Grabber ready before class, have your students complete the Play section. Students will gain experience in learning about the scissor linkages within the Grabber's design and begin considering how those linkages change the direction of force.
STEM Lab pacing guides preview the concepts that are taught in each section (Seek, Play, Apply, Rethink, Know) of the STEM Lab, relate the resources that teachers can use to teach those concepts and identify all the materials that are needed. The STEM Lab Pacing Guide is an editable Google doc that you can save to your device and modify based on your classroom constraints, and the needs of your students.
