playforce.org - Playforce: Learning from the games we play Demonstrations Purpose These demonstrations allow students to observe a wide variety of chemical reactions, most of which should not be performed by students for safety reasons. Be sure to keep students actively involved by directing them to make observations and consider questions during demonstrations. They could be asked to write down observations. Safety Wear eye protection and an apron throughout the demonstrations. Demonstration 1: Magnesium Burning Materials Magnesium ribbon, Mg, 3-5 cm strip Burner Crucible tongs Safety Caution students not to look at flame directly. The Demonstration Light the burner. 2Mg(s) + O 2 (g) --->2MgO(s) Demonstration 2: A Penny in Nitric Acid Erlenmeyer flask, 1000-mL Penny, pre-1983Conc. Conduct the reaction in the hood-the fumes are toxic. This reaction must be performed in a fume hood. Cu(s) + 4HNO 3 (aq) ---> Cu(NO 3 ) 2 (aq) + 2NO 2 (g) + 2H 2 O(l) Demonstration 3: Formation of a Precipitate Properly dispose of the lead compound formed. Demonstration 4: Replacement Reaction

Systems Thinking Games Systems Thinking Games, developed in partnership with Filament Games, are designed to be used by youth and educators to assess systems thinking skills both in the classroom and in afterschool contexts. A precursor to the GlassLab, this project brings together teachers, assessment experts and game designers and developers to collaboratively design and build a suite of games with data tools that support teachers in evaluating the way players approach problem-solving, and the strategies players use in understanding and interacting with complex systems. Currently, research is underway to develop assessment frameworks that yield valid and reliable assessment measures across the suite of digital games. To learn more, please join the Institute’s community for updates on our progress.

Path to the Periodic Table Lesson Overview This activity allows students to re-create the thought process that Dmitri Mendeleev and Julius Lothar Meyer went through to devise their early periodic tables. The students are given cards (provided at the end of the teacher activity page), each with the name of an element, its symbol, and some properties. The students are then asked to sort the elements into a table of some sort, in any way that makes sense to them. The activity is carried out in three steps. Student Ability Level and Grouping This activity is appropriate for high school introductory chemistry students or ninth-grade physical science students. Expected Student Background and Skills Students should have an understanding of elements and compounds, as well as of atoms and molecules. Time and Materials Required This activity can be completed in 20 to 30 minutes. Learning Objectives Students will gain an understanding of how the periodic table is organized.

Digital Games Transforming K-12 Assessment and Learning Many teachers are searching for new ways to engage their digital-native students. They are looking for, write researchers at Florida State, “alternative ways of teaching – ways that increase student engagement and yield a rich, authentic picture of the learner(s).” These researchers say more educators should take a look at the latest in digital games. Games that are designed not only to teach, but to help educators assess learning as it’s happening. GlassLab, a new nonprofit educational game design initiative, has just released its first game— SimCityEdu—based on the popular Simcity brand and called SimCityEDU: Pollution Challenge! The Games, Learning, and Assessment Lab, or GlassLab is a unique partnership between the nonprofit Institute of Play (known for their Quest to Learn schools), the game-design firm Electronic Arts, and others. “One of the things that we all get frustrated with is that kids get assessed in the spring and they get that data and feedback back in the fall.
Lesson on Calculating the Post-Mortem Interval | MSI Forensics Courtesy of Patti Bertino’s email post. The postmortem interval (PMI), also known as a time since death estimate, aids forensic scientists in death investigations. This lesson will introduce your students to the processes of decay and decomposition, forensic pathology, and forensic entomology. The lesson includes several video lectures, animations, and worksheet exercises with practical applications to explain the concept of PMI and accumulated degree hours (ADH). Intended Grade level11-12; content is intended for mature audiences Before you begin …Before starting, students should have a basic working knowledge of forensic science, death investigations, and Algebra. Class time requiredTwo 90-minute class periods Materials and Technology NeededComputer with Internet access and YouTube access enabled, basic calculator Link to website lesson:
beyond benign : green chemistry curriculum Green Chemistry Online Course for Educators Green Chemistry is the science of creating safe, energy efficient and non-toxic products and processes and offers a concrete path towards solving the environmental problems our society faces today. This course begins with an introduction to the 12 principles of green chemistry and then concentrates on the exploration and creation of green chemistry lesson plan materials. Educational resources that are proven vehicles for bringing green chemistry concepts to high school students will be introduced. These lesson plans are designed to integrate into current curriculum and meet national education standards in science and connecting disciplines. The materials are designed for high-tech, low-tech and no-tech implementation so that teachers withvarying resources have an avenue for implementation.
