In this inquiry based geologic field lab students will be estimating and measuring stream flow. Students will also map out a full scale live topography map of a dry streambed to help them estimate flow discharge. Students will use their journals to record their hypothesis, lab report questions, graphed data and evidence to backs up their observations.

This lab activity leads students to a better understanding of exo-endo- thermic processes. It also reinforces the necessity for proper lab safety equipment and disposal techniques.

Site with engaging and classroom-ready lessons. Good for K-12! Gets students introduced to aerospace, engineering, and rocketry.

This in class worksheet is designed to get students to think about and manipulate different accelerations in their head. Students work together with written descriptions of velocity and acceleration and draw the vectors in part one, and then turn that around in part two where they write descriptions of a car's motion based on the vector pictures they are given.

Students will create their own barometer in this activity and use it to discover atmospheric pressure and its relationship to the boiling points of liquids.

This lesson plan can be connected to a career-ready path, as it focuses on important concepts related to biodiversity and the impact of human activities on it. Students who are interested in pursuing careers in biology, environmental science, ecology, conservation, or other related fields would benefit from gaining knowledge and skills related to biodiversity. Additionally, the research skills, critical thinking, and problem-solving skills that students will develop in this lesson can be applied to a variety of careers. For example, individuals who work in conservation or environmental science may need to evaluate the impact of human activities on biodiversity and design solutions to mitigate negative effects. Overall, this lesson plan can help students gain valuable knowledge and skills that are relevant to a wide range of careers in the STEM fields.

This activity allows students to demonstrate their understanding of the Law of Conservation of Energy in the framework of student-designed investigations.

This activity is a laboratory activity where students gather data relating quantities of salt to the freezing point of water/ice.

This Immersion Unit provides a coherent series of lessons designed to guide students in developing deep conceptual understanding that is aligned with the standards, key science concepts, and essential features of classroom inquiry (as defined by the National Science Education Standards). Unit Overarching Concepts-Populations of living organisms change or stay the same over time as a result of the interactions between the genetic variations that are expressed by the individuals in the populations and the environment in which the population lives.-Science knowledge advances through inquiry.Unit Supporting Concepts-Individual organisms with certain variations of traits (adaptations) are more likely than others to survive and reproduce successfully.-When environmental conditions change it can affect the survival of both individual organisms and entire species.-Natural selection determines the differential survival of groups of organisms.-A small advantage in escaping a predator, resisting a drug, etc. can lead to the spread of a trait in a modest number of generations.-Mutations are a source of variation in an individualĺŐs genotype, and it can result in a change in phenotypeĺĐĺĐgood or bad.-Scientific progress is made by asking meaningful questions and conducting careful investigations, using appropriate tools and technology to perform tests, collect data, analyze relationships, and display data.-No matter how well one scientific explanation fits observations, a new explanation might fit them just as well or better, or might fit a wider range of observations. In science, thetesting, revising, and occasional discarding of explanations, new and old, never ends.This unit was developed through the large Math and Science Partnership project called System-wide Change for All Learners and Educators (SCALE), involving a collaboration among Los Angeles School District educators, California State University science and education faculty, and UW-Madison SCALE staff.

This Immersion Unit provides a coherent series of lessons designed to guide students in developing deep conceptual understanding that is aligned with the standards, key science concepts, and essential features of classroom inquiry (as defined by the National Science Education Standards). The Unit's overarching concepts are:- Naturally occurring variations of traits in a population are influenced by genetic and environmental factors and evolve over generations by selective processes.- Science knowledge advances through inquiry.Unit Supporting Concepts:- The variation of organisms within a species increases the likelihood that at least some members of the species will survive under changed environmental conditions.- Individual organisms with certain traits are more likely than others to survive and have offspring. Changes in environmental conditions can affect the survival of individual organisms and entire species.- Some variation in heritable characteristics exists within every species. One of these characteristics gives individuals an advantage over others in surviving and reproducing, and the advantaged offspring, in turn,are more likely than others to survive and reproduce.- New varieties of cultivated plants and domestic animals have resulted from selective breeding for particular traits.- Scientists differ greatly in whatphenomena they study and how they go about their work. Although there is nofixed set of steps that all scientists follow, scientific investigations usually involve the collection of relevant evidence, the use of logical reasoning, and the application of imagination in devising hypotheses and explanations to make sense of the collected evidence.- Important contributions to the advancement of science, mathematics, and technology have been made by different kinds of people, in different cultures, at different times.In Immersion Units, students learn academic content by working like scientists: making observations, asking questions, doing further investigations to explore and explain natural phenomena, and communicating results based on evidence. Immersion Units are intended to support teachers in building a learning culture in their classrooms to sustain studentsĺŐ enthusiasm for engaging in scientific habits of thinking while learning rigorous science content.The first step of this unit engages students in developing a class criteria for effective record-keeping in science by guiding an inquiry into scientists' notebooks.The unit includes very complete implementation instructions (Teacher's Guide pages), student pages, and formative and summative assessments.Students investigate:- how variation within a population is influenced by environmental factors- how environmental factors influence reproductive success in a populationThis unit was developed through the large Math and Science Partnership project called System-wide Change for All Learners and Educators (SCALE), involving a collaboration among Los Angeles School District educators, California State University science and education faculty, and UW-Madison SCALE staff.

This lab activity is designed to have students use their knowledge of balancing and identifying chemcial reactions and apply it in a fun and interesting way!

This is a lesson that gives students the opportunity to dive in and understand the different components of the FFA Creed. The students will have the opportunity to create something that is representative of the FFA Creed.

This is a Performance Task in which students are asked to interpret a graph that depicts a bike ride between two students algebraically.

An online, video-based methods course focusing on best practices in foreign language education for classroom management.

The project is the kick off to students picking a city and state for a new NFL franchise for a Sports Marketing course. Prior to creating a team name, students will research a city and state to determine it is appropriate for a new sports franchise. Prior to kicking off the project, as a class, it is ideal to review a map of where current NFL franchises are located. In addition, it is required that students find a city population of at least 150,000 people

This lesson unit is intended to help teachers assess how well students are able to: model a periodic situation, the height of a person on a Ferris wheel, using trigonometric functions; and interpret the constants a, b, c in the formula h = a + b cos ct in terms of the physical situation, where h is the height of the person above the ground and t is the elapsed time.
