Biology is designed for multi-semester biology courses for science majors. It is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand. To meet the needs of today’s instructors and students, some content has been strategically condensed while maintaining the overall scope and coverage of traditional texts for this course. Instructors can customize the book, adapting it to the approach that works best in their classroom. Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand—and apply—key concepts.

Dr. Royce observes a lesson on water evaporation in Ms. Maronpots class, gives her feedback, and visits again one week later. See the changes Ms. M makes in her lesson before and after the visit.

Students design a temporary habitat for a future classroom pet—a hingeback tortoise. Based on their background research, students identify what type of environment this tortoise needs and how to recreate that environment in the classroom. The students divide into groups and investigate the features of a habitat for a hingeback tortoise. These features include how many holes a temporary habitat may need, the animal’s ideal type of bedding, and how much water is needed to create the necessary humidity level within the tortoise’s environment. Each group communicates and presents this information to the rest of the class after they research, brainstorm, collect and analyze data, and design their final plan.

This activity is an investigation regarding evaporation and the factors that affect it.

Explore the concept of evaporative cooling through a hands-on experiment. Use a wet cloth and fan to model an air-conditioner and use temperature and relative humidity sensors to collect data. Then digitally plot the data using graphs in the activity. In an optional extension, make your own modifications to improve the cooler's efficiency.

The content briefs about Evaporator with its objective and also explains about the Factors affecting Evaporation

Students learn about energy and nutrient flow in various biosphere climates and environments. They learn about herbivores, carnivores, omnivores, food chains and food webs, seeing the interdependence between producers, consumers and decomposers. Students are introduced to the roles of the hydrologic (water), carbon, and nitrogen cycles in sustaining the worlds' ecosystems so living organisms survive. This lesson is part of a series of six lessons in which students use their growing understanding of various environments and the engineering design process, to design and create their own model biodome ecosystems.

Students explore heat transfer and energy efficiency using the context of energy efficient houses. They gain a solid understanding of the three types of heat transfer: radiation, convection and conduction, which are explained in detail and related to the real world. They learn about the many ways solar energy is used as a renewable energy source to reduce the emission of greenhouse gasses and operating costs. Students also explore ways in which a device can capitalize on the methods of heat transfer to produce a beneficial result. They are given the tools to calculate the heat transferred between a system and its surroundings.

This demonstration shows that an increase in temperature will speed up the water cycle. One outcome will be an increase in rainfall. A second outcome will be the increase in total evaporation of water and subsequent drought. Materials required include two aquariums, plastic wrap, 2 clamp lamps with 60 watt light bulbs, pebbles and rocks, modeling clay, blue food coloring, and water. Student worksheets, background information for teachers, and a scoring rubric are included. This is Activity 2 in Too Many Blankets, a module in the lesson series, Potential Consequences of Climate Variability and Change.

In this problem-based learning (PBL) activity, students take on the role of a student research scientist and explore the role of solar energy in determining climate. Students conduct experiments to observe how a change in water phase affects surface temperatures. Materials required for the investigation include 2 aquariums, dry sand or soil, two heat lamps, and two thermometers.The lesson is supported by teacher notes, answer key, glossary and an appendix with information about using PBL in the classroom. This is the second of three activities in Investigating the Climate System: Energy, a Balancing Act.

Relation of purpose of data to data requirements. Relation of data to costs.
Accuracy requirements of measurements and error propagation:
Related to a problem the required accuracy of measurements and the consequences for accuracy in the final result are discussed. Different types of errors are handled. Propagation of errors; for dependent and independent measurements, from mathematical relations and regression is demonstrated. Recapitulated is the theory of regression and correlation.
Interpretation of measurements, data completion: By standard statistical methods screening of measured data is performed; double mass analysis, residual mass, simple rainfall-runoff modelling. Detection of trends; split record tests, Spearman rank tests. Methods to fill data gaps and do filtering on data series for noise reduction.
Methods of hydrological measurements and measuring equipment: To determine quantitatively the most important elements in the hydrological cycle an overview is presented of most common hydrological measurements, measuring equipment and indirect determination methods i.e. for precipitation, evaporation, transpiration, river discharge and groundwater tables. Use, purpose and measurement techniques for tracers in hydrology is discussed.
Advantages and disadvantages and specific condition/application of methods are discussed. Equipment is demonstrated and discussed.
Areal distributed observation: Areal interpolation techniques of point observations: inverse distance, Thiessen, contouring, Kriging. Comparison of interpolation techniques and estimation of errors. Correlation analysis of areal distributed observation of rainfall
Design of measuring networks: Based on correlation characteristics from point measurements (e.g. rainfall stations) and accuracy requirements the design of a network of stations is demonstrated.

Hands-on group activity in where children go outside to find clouds, document with pictures, and identify them.

Benjamin Franklin is credited with saying, “Some people are weatherwise, but most are otherwise.” Ol’ Ben understood that weather can have a great effect on our everyday lives, and he knew the importance of having an understanding of what makes the atmosphere work (and not just knowing when it’s safe to fly a kite). In Meteo 3, we will examine all aspects of the weather. You’ll learn the fundamental processes that drive the atmosphere, along with some of the tools we use to measure those processes. You’ll also learn about large-scale weather systems, severe convection, tropical weather, and climate change. As a result, you’ll be a better consumer of weather information and forecasts. So… do you want to be weatherwise?

This activity is an investigation where students gather information about the rate of evaporation, interpret their findings, and apply this knowledge to the water cycle.

This activity is an outdoor lab in which students investigate the process of evaporation, record their findings, and use the data to make connections to the environment around them.
