Teachers can use an entire UL Xplorlabs module or portions of it. However, the modules are best used when kids are given enough time to design, and redesign when things fail. There are opportunities for teachers to ensure that students are driving the investigations. During the Xtreme Drop Test, students are provided with the procedure. Prior to this task, teachers could pose the question, "How could we design a fair test to determine if drop height influences hoverboard safety?" This gives students a chance to design their own procedure.
After students complete a module, be sure to check out the Xtensions section for creative challenges, resources on careers, and more. Also, try having students demonstrate learning by posting to the Xchange community.Continue reading Show less
UL Xplorlabs are modules designed to help middle school students "solve through science," specifically by creating solutions to real-world safety engineering problems. Currently, there are two modules: Fire Forensics and Portable Electrical Power. Modules include interactive videos, online simulations, and hands-on Xperiments that can be done in the classroom.
Students begin by watching a video that presents the challenge, like figuring out the point of origin of a fire or ensuring safe electric power in our portable devices. There are built-in, interactive pause points during the videos to make sure students understand the science in the problem. After watching the video, online simulations allow students to do experiments that wouldn't be safe in a classroom; one simulation has them drop hoverboards from different heights and see how that might impact the battery inside, while another has them look for evidence in a kitchen fire. They then engage in actual classroom experiments, such as building a calorimeter to measure heat release or testing materials for durability and heat performance to pick the best hoverboard lithium-ion battery enclosure.
While using UL Xplorlabs, students are safety scientists, testing innovations to reduce risk. This embraces the engineering practices from the Next Generation Science Standards (NGSS) that many other curricular tools ignore. As students discover the iterative nature of the scientific method, they'll get a chance to apply their knowledge of scientific phenomena through problem-solving and innovation. For example, after investigating a kitchen fire, students submit a claim about the cause of the fire and the evidence to support that claim.
Some of the pause points in the videos may not be that exciting, like clicking on hot spots to better understand how a lithium-ion battery works. However, the pause points are short, and students stay involved because they need to know the information (to make sure that their phones don't explode). Throughout both the simulations and the classroom experiments, students benefit from failure. Kids are reminded that getting things wrong isn't a bad thing -- it just means they've figured something out.
Key Standards Supported
Construct, use, and present arguments to support the claim that when the kinetic energy of an object changes, energy is transferred to or from the object.
Define the criteria and constraints of a design problem with sufficient precision to ensure a successful solution, taking into account relevant scientific principles and potential impacts on people and the natural environment that may limit possible solutions.
Matter and Its Interactions
Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.
Gather and make sense of information to describe that synthetic materials come from natural resources and impact society.
