STEP 2: CRAFT THE PBL

Would you know what to do in an emergency situation in the laboratory? What would you do if lab partners spilled acid on themselves? What should you do if you break a glass beaker or test tube? How do you properly light a Bunsen burner? Do you know who to report all accidents to? You have been hired by the Texas Education Agency (TEA) in Austin to produce an 8-10 minute video for Chemistry I students demonstrating the proper technique in lighting a Bunsen burner, heating a test tube, handling hot glass, disposing of hazardous and nonhazardous materials (including broken glass, solid waste, aqueous solutions, metals, acids, bases, unused chemicals, etc.). You will demonstrate how to accurately and precisely measure the volume of liquids using a graduated cylinder and burette (optional) and how to accurately and precisely mass solids with a triple beam balance and an electric balance. Lastly, you will give a demonstration on proper use and location of the fire blanket, fire extinguisher, gas shut off valve or button, eye wash, shower, MSDS notebooks, spill kit, apron, safety goggles, and anything else that your teacher deems essential for proper safety procedures or techniques in the Chemistry I laboratory. Safety symbols and general safety tips should be included. Create scenarios that compare and contrast proper technique with improper technique. Remember: Your audience will be Texas high school Chemistry I students. Creativity and proper editing are essential to grabbing your audience’s attention. And don’t forget to make it educational AND entertaining. You don’t have much time though! The TEA needs your team’s final production by the end of next week. So let’s get to it!

Explain Activity: Students discuss observations, ideas, questions and hypothesis with peers, facilitators, and groups. Learners apply labels to their experiences – thus developing common language, clarification/explanation of key concepts. Delivery of content begins with a discussion of the principles illustrated by the hands-on examples. In this way, the participants’ intuition is tapped to introduce terms and concepts that they may have heard. This approach leads naturally to an in-depth discussion of the science and mathematics concepts underlying the particular subject area.



Students will organize the scenarios (on the large note cards) into broad categories (i.e. general safety, measuring volume, measuring mass, how to put out a fire, chemical safety, etc.). They will then place the cards onto the poster boards in the order in which they will film the scenarios. Remind them they will need a very short introduction piece.



Students will work within their teams to practice the safety, measurement, and equipment use demonstrations and rehearse these short demos for the video.



The teacher will coach the students on proper and safe techniques while still allowing the students to use creative and entertaining ways to execute the demos. Remind students that in some scenarios proper and improper technique will need to be compared as an effective teaching tool for the audience.

Student filming may begin. Teams will decide who will film, direct, narrate, act, edit, etc. Roles may vary, be shared and rotated amongst team members. It is very important that the teams thoroughly examine the peer and teacher evaluation forms/rubrics, as this is the criterion by which they will be graded. Explain Activity Products and Artifacts: 1. Artifacts (KWL charts, journal entries, etc.) are evidence of the students’ thinking. 2. Products (flow charts, data tables, models, etc.) include checkpoints for progress throughout the PBL.

At its heart, the application of science and mathematics to design solutions to real-world problems is key to engaging students. Thus, providing PBL opportunities to students is a key component of STEM education. Opportunities to be creative in open-ended situations peak the interest of many students, providing an answer to the ubiquitous question: “Why do we need to know this?”



Remind students by saying, “Remember, your audience will be Texas high school

Chemistry I students. Creativity and proper editing are essential to grabbing your audience’s attention. And don’t forget to make it educational AND entertaining.”



Leads to opportunities for enrichment through further inquiry and investigation. What is the culminating task?



 

All students will view the edited and final videos as a class. Each student will evaluate the videos (see peer evaluation rubric). After each video is viewed the teams will discuss their opinions based on the peer evaluation forms, come to a consensus and turn in one peer evaluation for that video. The teams will then view the next video and repeat the above process until all videos are reviewed. Have a class discussion about what worked in each film and what needs improvement. Allow teams to take notes so that they may fix problems and resubmit their videos…remember, this is an important part of the engineering process. Have each student fill out a self-reflection form. Lead a class discussion about what the students learned and discovered during this project. Ask them what they discovered about working in teams and what they discovered about themselves. Have them share what they would do differently for their next project.
