This short video examines the recent melting ice shelves in the Antarctica Peninsula; the potential collapse of West Antarctic ice shelf; and how global sea levels, coastal cities, and beaches would be affected.

This activity is part of the Antarctica's Climate Secrets flexhibit. Students learn about and create models of glaciers and ice sheets, ice shelves, icebergs and sea ice.

Meet the Antibiotic Hunters—a team of professional and student scientists at the Tiny Earth Network who search for new antibiotics in the soil.

Resources available for learning about this lab include:
• Interactive cards designed to introduce students to scientists in a more personal way
• A video with a personal story that explains why the lab's research matters in real life
• Questions to consider that will spark connection, reflection, and conversation
• An interactive video experience where you can ask questions of scientists in the lab and learn about their research
• An inquiry-based activity that focuses on doing science, using some of the same science practices that the lab uses
• An educator guide with information about standards alignment, curriculum connections, and tips for using the media resources

These resources are part of Meet the Lab, a collection of educational resources for middle school science classrooms.

This task requires students to work with very large and small values expressed both in scientific notation and in decimal notation (standard form). In addition, students need to convert units of mass.

As a high school science educator at Lac Courte Oreilles Ojibwe school,  indigenous culture and teachings are incorporated into my instruction as much as possible. This text set was incorporated in my Astronomy class tying in Ojibwe Moons and seasonal constellations with northern Wisconsin phenology. A discussion of text set implementation is also included in this OER.Lac Courte Oreilles Ojibwe School is a Bureau of Indian Education/Tribally controlled school catering to students who are themselves tribally enrolled or descendants of a tribal member.

In this 3-act play for mathematics, students are presented with a question, "How many cubes are needed to balance the beam?".  The students will then watch a short video, answer some questions, and then determine solve the mathematical task using division of fractions. This 3-act play would be appropriate to use to introduce division by a fraction or as an assessment of learning after instruction.

Practical lab into the chemical reaction between calcium carbide and water and the resulting ignition of acetylene gas.

Application of Oral History to Economics: Family Economic History The assignment will connect an oral history approach to the examination of economic concepts such as opportunity cost of attending school, economic crises (inflation and unemployment, etc.), and standard of living over time. Particularly, students will interview parents, grandparents, or family members from older generations regarding the types of work they performed, economic decisions they have made, and the economic conditions while they were growing up. The project develops a student's ability to understand and integrate these concepts from a variety of perspectives and real world situation.

This 3-5 hour lesson through Google's Applied Digital Skills allows students to conduct research while learning about the credibility of sources. The resource includes lesson plans with 4 activities and an assessment rubric.

Students explore Hooke's law while working in small groups at their lab benches. They collect displacement data for springs with unknown spring constants, k, by adding various masses of known weight. After exploring Hooke's law and answering a series of application questions, students apply their new understanding to explore a tissue of known surface area. Students then use the necessary relationships to depict a cancerous tumor amidst normal tissue by creating a graph in Microsoft Excel.

This is a lesson plan designed to allow students to recall and use the properties of exponents to generate equivalent numeric expressions, identify the appropriate property to use and apply it correctly, and check the numerical value of an expression involving exponents without using a calculator. There is a fun matching activity for students at the end of the lesson to allow students to practice what they have learned and for the teacher to assess their learning by listening to and watching the students work and discuss strategy with each other.

Measuring the dimensions of nano-circuits requires an expensive, high-resolution microscope with integrated video camera and a computer with sophisticated imaging software, but in this activity, students measure nano-circuits using a typical classroom computer and (the free-to-download) GeoGebra geometry software. Inserting (provided) circuit pictures from a high-resolution microscope as backgrounds in GeoGebra's graphing window, students use the application's tools to measure lengths and widths of circuit elements. To simplify the conversion from the on-screen units to the real circuits' units and the manipulation of the pictures, a GeoGebra measuring interface is provided. Students export their data from GeoGebra to Microsoft® Excel® for graphing and analysis. They test the statistical significance of the difference in circuit dimensions, as well as obtain a correlation between average changes in original vs. printed circuits' widths. This activity and its associated lesson are suitable for use during the last six weeks of the AP Statistics course; see the topics and timing note below for details.

This short video from NASA discusses the role that salinity plays in Earth's climate and ocean circulation, focusing on the observations of the Aquarius satellite.

7 steps to shooting archery, finding eye dominance, scoring, whistle commands, parts of a bow and arrow, quiz, and score sheets for scoring.

Spreadsheets across the Curriculum Activity. Student build spreadsheets that allow them to estimate pi using the same iterative process as Archimedes.

The famous story of Archimedes running through the streets of Syracuse (in Sicily during the third century bc) shouting ''Eureka!!!'' (I have found it) reportedly occurred after he solved this problem. The problem combines the ideas of ratio and proportion within the context of density of matter.

Students explore the interface between architecture and engineering. In the associated hands-on activity, students act as both architects and engineers by designing and building a small parking garage.

Students create four-legged walking robots and measure how far they travel across different types of surfaces. They design and create "shoes" to add to the robots' feet and observe the effect of their modifications on the net distance traveled across the various surface types. This activity illustrates how the specialized locomotive features of different species help them to survive or thrive in their habitat environments. The activity is best as an enrichment tool that follows a lesson that introduces the concept of biological adaptation to students.

This lesson sequence guides students to learn about the geography and the unique characteristics of the Arctic, including vegetation, and people who live there. Students use Google Earth to explore the Arctic and learn about meteorological observations in the Arctic, including collecting their own data in hands-on experiments. This is the first part of a three-part curriculum about Arctic climate.
