Instructional Practices
 
Teaching from a range of complex text is optimized when teachers in all subject areas implement the following strategies on a routine basis: 

  1. Ensuring wide reading from complex text that varies in length.
  2. Making close reading and rereading of texts central to lessons.
  3. Emphasizing text-specific complex questions, and cognitively complex tasks, reinforce focus on the text and cultivate independence.
  4. Emphasizing students supporting answers based upon evidence from the text.
  5. Providing extensive research and writing opportunities (claims and evidence).


Science and Engineering Practices
 (NRC Framework for K-12 Science Education, 2010)

  • Asking questions (for science) and defining problems (for engineering).
  • Developing and using models.
  • Planning and carrying out investigations.
  • Analyzing and interpreting data.
  • Using mathematics, information and computer technology, and computational thinking.
  • Constructing explanations (for science) and designing solutions (for engineering).
  • Engaging in argument from evidence.
  • Obtaining, evaluating, and communicating information.

 


English Language Development ELD Standards Special Notes Section:

Certain disasters are more appropriate for particular grade levels. Each scenario takes between 20 and 45 minutes to play, depending on the disaster for which your students are trying to prepare. There are five scenarios available, hurricane, tsunami, flood, earthquake, and wildfire. Each scenario can be played on easy, medium or hard difficulty levels. As with life, there are no "perfect solutions" to each scenario and no "perfect score", so students can play multiple times and the scenarios will still be slightly different.These simulation are part of a larger website that provides multiple links for natural disasters.

Lesson Plans

The Surprising World of Complex Systems:

This lesson introduces students to complex systems and to basic concepts from the field of system dynamics that lie at the heart of systems thinking. These concepts include stocks and flows, feedback loops, unintended consequences, and the basic principle that the behavior of complex systems can best be understood by looking at the system as a whole, and specifically by analyzing the system’s underlying structure. The lesson introduces these topics through an immersion in (and a role-play simulation of) the dynamics of urban recycling systems, many of which have been thrown into crisis in the past two years. Through this current-affairs example of complex systems in crisis, we identify some key structural features that help to explain how these systems behave over time. We also discover how well-intentioned action can cause negative unintended consequences when we try to intervene in a complex system without understanding how it operates.

Type: Lesson Plan

Sea Level Rise: The Ocean's Uplifting Experience:

The purpose of this lesson is to introduce students to the concept of sea level rise as it occurs through climate change by having them examine 3 specific parameters:  ice distribution, thermal expansion, and analyzing and interpreting data.  The lesson and activities within the lesson were designed using the three dimensions of the Framework for K-12 Science Education and the Next Generation Science Standards – specifically crosscutting concepts, science and engineering practices, and disciplinary core ideas. While there isn’t any required pre-requisite learning required for this lesson, a general understanding of sea-level rise, glaciers, and climate may be beneficial to students. During classroom breaks, pairs of students will develop/discuss their models, revise their interpretations of their models or data, and think-pair-share their thoughts on the investigation segments.

Type: Lesson Plan

CO2: Find Out What It Means to You:

This BLOSSOMS lesson discusses Carbon Dioxide, and its impact on climate change. The main learning objective is for students to become more familiar with human production of Carbon Dioxide gas, as well as to gain an awareness of the potential for this gas to effect the temperature of Earth’s atmosphere. This lesson should take about an hour to complete. In order to complete the lesson, the teacher will need: printed copies of signs representing the different products and processes that take place in the carbon cycle (included), samples of matter that represent those products, handouts for the students to create a graphic of the carbon cycle (included) and graph paper or graphing software for students to create graphs. In the breaks of this BLOSSOMS lesson, students will be creating models of the carbon cycle as well as observing experiments and analyzing data from them. It is hoped that this lesson will familiarize students with ways in which carbon moves through our environment and provide them with some personal connection to the impact that an increased concentration of CO2 can have on air temperature. The goal is to spark their interest and hopefully to encourage them to ask and investigate more questions about the climate. 

Type: Lesson Plan

Meet the Family: Investigating Primate Relationships:

Finally, they will look at the tree in the context of time in order to see divergence times.

This lesson introduces students to Green Chemistry, the design of chemical products and processes that reduce or eliminate the use and/or the generation of hazardous substances. Green chemistry is a proactive approach to pollution prevention that teaches chemists how to develop products and materials in a manner that does not use hazardous substances, thus avoiding much waste, hazards and associated costs. The goal of this lesson is to introduce students to the 12 Principles of Green Chemistry and how they relate to a chemical process. These principles provide a framework for scientists, engineers and chemistry students to use when designing new materials, products, processes, and systems. The Principles focus on sustainable design criteria and have proven to be the source of innovative solutions to a wide range of problems. Through this lesson, students will also use weight and measurement to understand the concept of a recipe as it is applied to a chemical process and think critically about that process and how it might be improved. Students will be asked to use a wasteful, inefficient procedure to make glue and be challenged to improve the procedure-during which they will unknowingly use the 12 Principles. Before starting this lesson, students should have been introduced to the periodic table and properties of matter. The estimated time for this lesson is 50-60 minutes.
