Project-based learning, or PBL, challenges students to design and engage in more authentic, extended, and complex learning. But while PBL is a trusted strategy for increasing student engagement and learning, it's not easy to orchestrate. There are tons of moving pieces, and if you're doing it right, students will be engaging in a variety of interest-driven projects all with various needs and on different schedules. So how do you manage it all? Tech can be a huge help. This list gathers some useful productivity and organization tools that can help both teachers and students keep track of, finish, and assess projects. There are also a few tools designed specifically for PBL, as well as plug-and-play PBL experiences.
Students learn about traffic lights and their importance in maintaining public safety and order. Using a Parallax® Basic Stamp 2 microcontroller, students work in teams on the engineering challenge to build a traffic light with a specific behavior. In the process, they learn about light-emitting diodes (LEDs), and how their use can save energy. Students also design their own requirements based on real-world observations as they learn about traffic safety and work towards an interesting goal within the realm of what is important in practice. Knowledge gained from the activity is directly transferrable to future activities, and skills learned are scalable to more ambitious class projects.
This lesson applies the science and math of the rotation of a sphere to water and wind movements on Earth. Students are introduced to convection, the Trade Winds and the Coriolis Force. Using an online visualizer, students generate trajectories and then analyze course patterns and latitudinal changes in strength. Note that this is lesson two of five on the Ocean Motion website. Each lesson investigates ocean surface circulation using satellite and model data and can be done independently. See Related URL's for links to the Ocean Motion Website that provide science background information, data resources, teacher material, student guides and a lesson matrix.
Diagnostic Imaging principles and concepts are augmented by the presentation of imaging for common clinical conditions. Guiding principles related to minimizing radiation exposure and requesting the most appropriate imaging examination is addressed. Static images are enhanced by the ability to access images stored and displayed on an Html-5 compatible, Dicom image viewer that simulates a simple Picture Archive and Communication system (PACS). Users can also access other imaging from the Dicom viewer (ODIN), beyond the basic curriculum provided, to further advance their experience with viewing diagnostic imaging pathologies.This book is also available in three other digital formats: ePUB (for Nook, iBooks, Kobo etc.), PDF (regular print), PDF (large print).

This is a lesson about the vertical dimension of the atmosphere and includes four activities. Activity 1 Introduces concepts related to distance, including length and height and units of measurement. Students are asked to make comparisons of distances. In activity 2, students learn about the vertical profile of the atmosphere. They work with a graph and plot the heights of objects and the layers of the atmosphere: troposphere, stratosphere, mesosphere, thermosphere, and exosphere. In activity 3, students learn about other forms of visual displays using satellite imagery. They compare images of the same weather feature, a hurricane, using two different images from MODIS and CALIPSO. One image is looking down on the hurricane from space, the other looks through the hurricane to display a profile of the hurricane. Activity 4 reinforces the concept of the vertical nature of the atmosphere. Students will take a CALIPSO satellite image that shows a profile of the atmosphere and use this information to plot mountains and clouds on their own graph of the atmosphere. The recommended order for the activities is to complete the first two activities on day one, and the second two activities on day two. Each day will require approximately 1 to 1.5 hours.
In this activity, students take the age old concept of etch-a-sketch a step further. Using iron filings, students begin visualizing magnetic field lines. To do so, students use a compass to read the direction of the magnet's magnetic field. Then, students observe the behavior of iron filings near that magnet as they rotate the filings about the magnet. Finally, students study the behavior of iron filings suspended in mineral oil which displays the magnetic field in three dimensions.
