This task uses language, "half of the stamps," that students in Grade 5 will come to associate with multiplication by the fraction 12. In Grade 3, many students will understand half of 120 to mean the number obtained by dividing 120 by 2. For students who are unfamiliar with this language the task provides a preparation for the later understanding that a fraction of a quantity is that fraction times the quantity.

After using the historical development of the Standard Model to develop introductory understanding, students link to OPAL and DELPHI data archives from CERN to identify and study the tracks from elementary particles.

To navigate, you must know roughly where you stand relative to your designation, so you can head in the right direction. In locations where landmarks are not available to help navigate (in deserts, on seas), objects in the sky are the only reference points. While celestial objects move fairly predictably, and rough longitude is not too difficult to find, it is not a simple matter to determine latitude and precise positions. In this activity, students investigate the uses and advantages of modern GPS for navigation.

This activity is used to introduce the different properties of states of matter, by testing an unknown substance with household materials to determine which state of matter most closely resembles the material. It also can invole data collection, reasoning, grph making, and presentation of findings.

This activity is a lab investigation where students observe the four states of matter. At the end of the investigation students should be able to know that the differences among the physical states depend on the distance between the atoms or molecules and on the rate of movement of the atoms or molecules. And, that pressure and temperature control these two factors.

This hands-on activity explores the concept of static electricity. Students attract an O-shaped piece of cereal to a charged comb and watch the cereal jump away when it touches the comb. Students also observe Styrofoam pellets pulling towards a charged comb, then leaping back to the table.

Student groups rotate through four stations to examine light energy behavior: refraction, magnification, prisms and polarization. They see how a beam of light is refracted (bent) through various transparent mediums. While learning how a magnifying glass works, students see how the orientation of an image changes with the distance of the lens from its focal point. They also discover how a prism works by refracting light and making rainbows. And, students investigate the polar nature of light using sunglasses and polarized light film.

Students will statistically analyze data gathered in reference to the Abraham Lincoln penny.

This webinar will introduce the integration of JASP Statistical Software (https://jasp-stats.org/) with the Open Science Framework (OSF; https://osf.io). The OSF is a free, open source web application built to help researchers manage their workflows. The OSF is part collaboration tool, part version control software, and part data archive. The OSF connects to popular tools researchers already use, like Dropbox, Box, Github, Mendeley, and now is integrated with JASP, to streamline workflows and increase efficiency.

Students learn that math is important in navigation and engineering. They learn about triangles and how they can help determine distances. Ancient land and sea navigators started with the most basic of navigation equations (speed x time = distance). Today, navigational satellites use equations that take into account the relative effects of space and time. However, even these high-tech wonders cannot be built without pure and simple math concepts — basic geometry and trigonometry — that have been used for thousands of years.

Students learn about the strength of bones and methods of helping to mend fractured bones. During a class demonstration, a chicken bone is broken by applying a load until it reaches a point of failure (fracture). Then, working as biomedical engineers, students teams design their own splint or cast to help repair a fractured bone, learning about the strength of materials used.

This problem can be solved in more than one way. The choice in solution method may reflect the comfort and mathematical sophistication of the student.

This is a multi-step problem since it requires more than two steps no matter how it is solved. The problem is not scaffolded for the student, but each step is straightforward and should follow from the previous with a careful reading of the problem.

This activity is a lecture where students learn the basic concept behind stoichiometry, mole ratios.

This strategy guide introduces the concept of using Exit Slips in the classroom to help students reflect on what they have learned and express what or how they are thinking about the new information. Exit Slips easily incorporate writing into the content area classroom and require students to think critically.

The Exit Slip strategy is used to help students process new concepts, reflect on information learned, and express their thoughts about new information. This strategy requires students to respond to a prompt given by the teacher, and is an easy way to incorporate writing into many different content areas. Furthermore, the Exit Slip strategy is an informal assessment that will allow educators to adapt and differentiate their planning and instruction.

Effective differentiation begins with purposeful assessment. In this strategy guide, you’ll learn how to construct an authentic performance-based reading assessment that will give you access to students’ thinking before, during, and after reading.

In this strategy, students read aloud to each other, pairing more fluent readers with less fluent readers. Likewise, this strategy can be used to pair older students with younger students to create “reading buddies.” Additionally, children who read at the same level can be paired to reread a text that they have already read, for continued understanding and fluency work. This research-based strategy can be used with any book or text in a variety of content areas, and can be implemented in a variety of ways.
