The Tennessee Blue Book serves as a manual of useful information on our state and government, both past and present. It contains information on the makeup of Tennessee state government, state history, national and state constitutions, most recent election results, and census data.
This activity is used to introduce the different properties of states of matter, by testing an unknown substance with household materials to determine which state of matter most closely resembles the material. It also can invole data collection, reasoning, grph making, and presentation of findings.
This is a task from the Illustrative Mathematics website that is one part of a complete illustration of the standard to which it is aligned. Each task has at least one solution and some commentary that addresses important aspects of the task and its potential use.

To evaluate the different integumentary systems found in the animal kingdom, students conduct an exploratory research-based lab. During the activity, students create a model epidermis that contains phosphorescent powder and compare the results to a control model. After learning about the variations of integumentary systems—systems that comprise the skin and other appendages that act to protect animal bodies from damage—students act as engineers to mimic animal skin samples. Their goal is to create a skin sample that closely represents the animal they are mimicking while protecting the base ‘epidermis’ from UV light.
Identity and access management is one of the key focus area for industries considering the volume, sensitivity of data that is being accessed, processed by individuals from multiple channels and from multiple places. To make sure right person has the right access to the right data at the right time becomes critical aspect to protect confidentiality, integrity and availability of the information. Authenticating users is a first thing to do before we allow anybody to access information. There are multiple ways how we authenticate users for ex. combination of username and password, username, password and an additional factor such as One time password(OTP), Email, Mobile push notification etc(Multifactor authentication).
The MEF is a document presenting how a Modern Education Framemork for adult education should be build in the field of wastewater management
Students work as engineers to design and test trebuchets (in this case LEGO® MINDSTORMS® robots) that can launch objects. During the testing stage, they change one variable at a time to study its effect on the outcome of their designs. Specifically, they determine how far objects travel depending on their weights. As students learn about the different components of robot design and the specific function controls, they determine what design features are important for launching objects.
This is a continuation of Fundamentals of Physics, I (PHYS 200), the introductory course on the principles and methods of physics for students who have good preparation in physics and mathematics. This course covers electricity, magnetism, optics and quantum mechanics.
This article features children's literature about weather, climate, and climate change. What’s the difference between weather and climate? How do scientists observe, measure, and predict weather phenomena? How is Earth’s climate changing, and why? This month’s bookshelf will help students develop a solid grasp of weather-related concepts. It will also introduce students to global warming and climate change and inspire them to do what they can to combat the problem.
Consumers often measure whether they got a good deal on a purchase by the difference between the original price and a sales price. The bigger the difference is, the better the deal feels. The original price a consumer is exposed to becomes a reference point, or an anchor. The April 2021 issue of Page One Economics® Focus on Finance explains the anchoring effect and the role it plays in the decisionmaking process when it comes to what consumers are willing to pay for a good or service.
Students explore the properties of composites using inexpensive materials and processing techniques. They create beams using Laffy Taffy and water, and a choice of various reinforcements (pasta, rice, candies) and fabricating temperatures. Student groups compete for the highest strength beam. They measure flexure strength with three-point bend tests and calculations. Results are compared and discussed to learn how different materials and reinforcement shapes affect material properties and performance.
This course provides an introduction to the design of feedback systems. Topics covered include: properties and advantages of feedback systems, time-domain and frequency-domain performance measures, stability and degree of stability, root locus method, Nyquist criterion, frequency-domain design, compensation techniques, application to a wide variety of physical systems, internal and external compensation of operational amplifiers, modeling and compensation of power converter systems, and phase lock loops.
This lesson introduces students to the effects of magnetic fields in matter addressing permanent magnets, diamagnetism, paramagnetism, ferromagnetism, and magnetization. First students must compare the magnetic field of a solenoid to the magnetic field of a permanent magnet. Students then learn the response of diamagnetic, paramagnetic, and ferromagnetic material to a magnetic field. Now aware of the mechanism causing a solid to respond to a field, students learn how to measure the response by looking at the net magnetic moment per unit volume of the material.
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.
The airplanes unit begins with a lesson on how airplanes create lift, which involves a discussion of air pressure and how wings use Bernoulli's principle to change air pressure. Next, students explore the other three forces acting on airplanes thrust, weight and drag. Following these lessons, students learn how airplanes are controlled and use paper airplanes to demonstrate these principles. The final lessons addresses societal and technological impacts that airplanes have had on our world. Students learn about different kinds of airplanes and then design and build their own balsa wood airplanes based on what they have learned.
The Educators Evaluating the Quality of Instructional Products (EQuIP) Rubric for science provides criteria by which to measure the alignment and overall quality of lessons and units with respect to the Next Generation Science Standards. The purpose of the rubric and review process is to: (1) provide constructive criterion-based feedback to developers; (2) review existing instructional materials to determine what revisions are needed; and (3) identify exemplars/models for teachers’ use within and across states.
Students use measured ages and offset of quaternary surfaces to determine vertical slip rates of a young fault. Students then must determine if vertical slip rates have varied significantly through time.

The MC1R gene, in part, controls deer mouse fur. Two alleles, RD and RL, in different combinations lead to light, medium, or dark brown fur. Students learn how to calculate relative allele frequencies, and then investigate how these frequencies may change over time as the environment in which the deer mice live changes. The activity is divided into four steps, which guide students to a deeper understanding of how evolution is measured.
Students will utilize previously gained knowledge about the impact of land management practices on ecosystems to design, conduct and analyze an experiment to measure biodiversity and/or invertebrate ecosystem role in a field community. They will identify ecosystems that have been heavily and lightly impacted by human activities and make predictions about biodiversity in the area. They will then test and analyze the information gathered and apply what this means about the biodiversity in these ecosystems and the implications this may have on the region.
