It's Meeko's time to shine! This week's Wildlife Wednesdays feature put the spotlight on one of your favorite animal ambassadors: Meeko, the albino raccoon! Chief Wildlife Officer Harvey Webster and Animal Programs Coordinator Nicole Episcopo gave us a behind-the-scenes look at enrichment and training for our bushy-tailed friend, and shared fun facts about thie Ohio-native species.

This choice board, created from Google Slides, includes 20 different eBooks and videos about the state of Ohio. Share this choice board directly with students and allow them to choose the eBooks and videos they would like to read or watch to learn more about the topic.

Students learn about the differences between types of water (surface and ground), as well as the differences between streams, rivers and lakes. Then, they learn about dissolved organic matter (DOM), and the role it plays in identifying drinking water sources. Finally, students are introduced to conventional drinking water treatment processes.

Commercial fishing nets often trap "unprofitable" animals in the process of catching target species. In this activity, students experience the difficulty that fishermen experience while trying to isolate a target species when a variety of sea animals are found in the area of interest. Then the class discusses the large magnitude of this problem. Students practice data acquisition and analysis skills by collecting data and processing it to deduce trends on target species distribution. They conclude by discussing how bycatch impacts their lives and whether or not it is an important environmental issue that needs attention. As an extension, students use their creativity and innovative skills to design nets or other methods, theoretically and/or through hands-on prototyping, that fisherman could use to help avoid bycatch.

Bycatch, the unintended capture of animals in commercial fishing gear, is a hot topic in marine conservation today. The surprisingly high level of bycatch about 25% of the entire global catch is responsible for the decline of hundreds of thousands of dolphins, whales, porpoises, seabirds and sea turtles each year. Through this curricular unit, students analyze the significance of bycatch in the global ecosystem and propose solutions to help reduce bycatch. They become familiar with current attempts to reduce the fishing mortality of these animals. Through the associated activities, the challenges faced today are reinforced and students are stimulated to brainstorm about possible engineering designs or policy changes that could reduce the magnitude of bycatch.

Students learn that fats found in the foods we eat are not all the same; they discover that physical properties of materials are related to their chemical structures. Provided with several samples of commonly used fats with different chemical properties (olive oil, vegetable oil, shortening, animal fat and butter), student groups build and use simple LEGO MINDSTORMS(TM) NXT robots with temperature and light sensors to determine the melting points of the fat samples. Because of their different chemical structures, these fats exhibit different physical properties, such as melting point and color. This activity uses the fact that fats are opaque when solid and translucent when liquid to determine the melting point of each sample upon being heated. Students heat the samples, and use the robot to determine when samples are melted. They analyze plots of their collected data to compare melting points of the oil samples to look for trends. Discrepancies are correlated to differences in the chemical structure and composition of the fats.

Convert metric measurements to U.S. Measurements and the reverse, too. Easy to follow tables have sections for area, length, mass,temperature and volume.

This video [3:38] segment from American Masters' James Baldwin: The Price of the Ticket illustrates the activist's intolerance for violence or racial hatred expressed by anyone, black or white. In the mid-1960s, Baldwin's principles put him in conflict with Eldridge Cleaver and a new black militant faction, who advocated a reciprocal response to the violence they often experienced. Baldwin struggled with the paradox of acknowledging the violent conditions facing many black Americans and his advocacy for the brotherhood of man. Baldwin could never truly join the black militants as he strongly believed that "the world is held together by the love and the passion of a very few people." Teaching materials are included.

This set of a teacher and student guides provides instruction on a 2-3 day series of activities about Le Chatelier’s principle, which shows the effect of changes to conditions in an equilibrium reaction. Students work in pairs or groups to develop their concepts of equilibrium and the effects of changing the amount of reactants or products on an equilibrium system. The concepts are presented and analyzed using graphical representations, qualitative lab data, and modelling. The first part addresses the misconception that equal amounts are required for equilibrium through using a mini-activity that involves the transfer of water between beakers. The second part is a lab activity where students will see how an equilibrium system reacts to a change in concentration. The third part uses manipulatives to understand how an equilibrium operates using the mathematical equilibrium constant (Ksp) at the particulate view.

In this lesson, students will become familiar with glaciers, how they form, move, and shape the land.

Students learn about linear programming (also called linear optimization) to solve engineering design problems. As they work through a word problem as a class, they learn about the ideas of constraints, feasibility and optimization related to graphing linear equalities. Then they apply this information to solve two practice engineering design problems related to optimizing materials and cost by graphing inequalities, determining coordinates and equations from their graphs, and solving their equations. It is suggested that students conduct the associated activity, Optimizing Pencils in a Tray, before this lesson, although either order is acceptable.

Learn about allele frequencies in populations and how they differ from genotype frequencies. [7:27]

Khan Academy learning modules include a Community space where users can ask questions and seek help from community members. Educators should consult with their Technology administrators to determine the use of Khan Academy learning modules in their classroom. Please review materials from external sites before sharing with students.

In this inquiry activity students work in groups to investigate allelopathy via research, using the scientific method to plan and carry out an experiment, and creating a formal written report and oral presentation.

Using the AMAM’s renowned collection of Asian art, more than 20 lesson plans connect different topics of study with the arts and cultures of Asia. They are based on Ohio’s Learning Standards for all ages and interdisciplinary areas.

Developed through generous grants from the Freeman Foundation, each lesson includes: learning objectives and assessment questions, a hands-on activity, related state and national learning standards, vocabulary words, differentiations for K-12 levels, a slideshow with supplemental maps and images, and additional resource links.
