Inquiry-Based Investigation on the Internet : Sound and the Human Ear
This online exploration of sound energy and the human ear includes an activity where students formulate, justify, and evaluate a number of predictions about sound. The investigation, which is intended for two class periods, or approximately 90 minutes of instructional time, is divided into two parts--Sound Waves and Anatomy of the Human Ear. Although these activities can be conducted separately, they build on each other and connect life science and physical science when conducted sequentially.

El Nino vs. La Nina
This site offers images and animations showing global sea surface temperature (SST) and sea surface height (SSH) during El Nino of 1997-1998 and La Nina of 1998-1999. Images show the difference between the normal SST for that time of year and the actual temperature, clearly showing the higher and lower Pacific temperatures associated with the El Nino and La Nina events of 1997-1999 respectively. Thus the annual cycle and climatology have been removed from the data. Animations use Pathfinder and

Peripheral Vision Lab
Students practice reading large letters on index cards with their peripheral vision. Then they repeat the experiment while looking through camera lenses, first a lens with a smaller focal length and then a lens with a larger focal length. They then complete a worksheet and explain how the experiment helps them solve the challenge question from lesson 1.

It's Tiggerific!
In Lesson 3, as part of the Research and Revise step students investigate potential energy held within springs (elastic potential energy). Class begins with a video of either spring shoes or bungee jumping. Students then move on into notes and problems as a group. A few questions are given as homework. The Test Your Mettle section concludes lesson includes a dry lab that involves pogo sticks solidifies the concepts of spring potential energy, kinetic energy, and gravitational energy, as well as

Bone Density Math and Logarithm Introduction
Students should have discovered in their reading from Activity 1 the term “logarithm.” It is at this point that students will begin their study of logarithms. Specifically, they will be examining the definition, history, and relationship to exponents. (Specifically, they will be rewriting exponents as logarithms and vice versa, evaluating expressions, solving for a missing piece.) Students will continue their examination of logarithms by studying the properties of logarithms (Multiplication/

Maximum Power Point
Students learn how to find the maximum power point (MPP) of a photovoltaic (PV) panel in order to optimize its efficiency at creating solar power. They also learn about real-world applications and technologies that use this technique, as well as Ohm’s law and the power equation, which govern a PV panel’s ability to produce power.

Problem Solving
Students are introduced to a systematic procedure for solving problems through a demonstration and then the application of the method to an everyday activity. The unit project is introduced to provide relevance to subsequent lessons.

Energy Perspectives
Students utilize data tables culled from the US DOE Energy Information Agency to create graphs to illustrate what types of energy we use and how we use it. An MS Excel workbook with several spreadsheets of data is provided. Students pick (or the teacher assigns) one of the data tables for the students to create a plot from and interpret the information provided. Each group of students then shares their interpretation and new perspectives on energy resources and use with the rest of the class.

Energy Resources and Systems
Several activities are included to teach and research the differences between renewable and non-renewable resources and various energy resources. The students work with a quantitative, but simple model of energy resources to show how rapidly a finite, non-renewable energy sources can be depleted, whereas renewable resources continue to be available. The students then complete a homework assignment or a longer, in-depth research project to learn about how various technologies that capture energy

Biomedical Devices for the Eyes
Students examine the structure and function of the human eye, learning some amazing features about our eyes, which provide us with sight and an understanding of our surroundings. Students also learn about some common eye problems and the biomedical devices and medical procedures that resolve or help to lessen the effects of these vision deficiencies, including vision correction surgery.

Sound Booth Construction
Students explore the sound dampening ability of numerous materials by designing and prototyping model sound booths. As a result, students learn about how sound is reflected, absorbed and travels through various materials, thus giving them an overview of sound dampening, energy absorption and sound propagation in the context of engineering. Students also create blueprints and document their findings in a formal lab report.

Cell Celebration!
Students look at the components of cells and their functions. The lesson focuses on the difference between prokaryotic and eukaryotic cells. Each part of the cell performs a specific function that is vital for the cell’s survival. Bacteria are single-celled organisms that are very important to engineering. Engineers can use bacteria to break down toxic materials in a process called bioremediation, and they can also kill or disable harmful bacteria through disinfection.

All Caught Up
Commercial fishing nets often trap unprofitable animals in the process of catching their target species. In the following activity, students will experience the difficulty that fishermen experience while trying to isolate a target species when a variety of animals are found in the area of interest. The class will then discuss the large magnitude of this problem. Students will practice their data acquisition and analysis skills, through the collection of data and processing of this information to

Compare Fabric Materials
Students will look at different types of fabric and their respective individual properties. Using a magnifying glass and sandpaper they will test and observe the weave of fabrics and the wear quality of sample fabrics. By comparing the qualities of different fabrics they will better understand why there are so many different types of fabric and be able to recognize or suggest different uses for them.

Do as the Romans: Construct an Aqueduct!
In this activity, students work with specified materials to create aqueduct components that will transport 2 liters of water across a short distance in their classroom. The goal is to build an aqueduct that will supply Aqueductis, a Roman city, with clean water for private homes, public baths, and glorious fountains.

Sound for Sight
Echolocation is the ability to orient by transmitting sound and receiving echoes from objects in the environment. As a result of a Marco-Polo type activity and subsequent lesson, students learn basic concepts of echolocation. They use these concepts to understand how dolphins use echolocation to locate prey, escape predators, navigate their environment, such as avoiding gillnets set by commercial fishing vessels. Students will also learn that dolphin sounds are vibrations created by vocal organs

Do Different Colors Absorb Heat Better?
Students test whether the color of a material affects how much heat it absorbs. Students will place an ice cube in a box made of colored paper (one box per color; white, yellow, red and black), which they will place in the sun. The students will make prediction as to which color will melt the ice cube first. They will record the order and time required for the ice cubes to melt.
