Subject: Science (7), or Science (7)
Title: The Ins and Outs of Digestion
Description: The Ins and Outs of Digestion Lab includes Hands-On and Inquiry-Based activities. Students will design an experiment to determine the effect of introducing new foods in a baby’s diet.  Students will do an activity to determine the correct placement of various organs of the digestive system. Students will hypothesize about why food spends various amounts of time in a particular organ.  Using common household materials, students will create a model of the digestive system.  Students will do an activity comparing mechanical and chemical digestion.  The module also includes a video on the digestive system, a presentation, a word search puzzle and a bingo game emphasizing vocabulary.


Subject: Science (7), or Science (7)
Title: The Barn Owl Pellet Lab
Description: The Barn Owl Pellet Lab includes hands-on inquiry based activities.  The lab provides the opportunity for students to dissect two Barn Owl pellets.  This allows a comparison between the data collected from the two pellets.  The student worksheets require students to make predictions; perform mathematical calculations; construct a graph; classify bones into types; separate bones by prey type; and draw conclusions about the owl’s environment based on the dissection findings.


Subject: Science (7)
Title: Immunology Using ELISA Simulation
Description: The Immunology Using ELISA Simulation module includes Hands-On and Inquiry-Based activities.  In this module, students will explore how the principles of antibody-based human immunity apply to a common laboratory test called ELISA (enzyme-linked-immunoabsorbant-assay). ELISA is a common method for testing blood serum for the presence of antibodies which the body produces to guard against disease-causing pathogens such as bacteria and viruses.  Students will work in pairs to perform a hands-on indirect ELISA test which will detect the presence of infection using simulated serum samples, antibodies, antigens or disease agents.  Using hypothetical scenarios, the students will investigate and diagnose six fictitious patients for the following diseases:  HIV, Lyme Disease, Avian Influenza (Bird Flu), and West Nile Virus.  Another activity in this module utilizes Glo Germ lotion to demonstrate how germs can be spread through human contact such as handshaking.  The module also contains a power point presentation, links to animated videos on the ELISA procedure and the way the immune system works and an interactive activity using the scientific method to determine the source of a disease outbreak in an epidemiological setting.


Subject: Science (7)
Title: Flower and Fruit Dissection with Microscopic Observation of the Lily Anther and Ovulary
Description: The Flower and Fruit Dissection Lab with microscopic observation of the lily anther and ovulary module includes Hands-0n and Inquiry-Based activities.  Students will dissect various types of large flowers such as lilies or hibiscus.  As the students remove the various plant reproductive structures, they will identify and count the numbers of each structure and preserve them on a collection card.  The students will  dissect samples on one of the three types of fruits, which are simple, aggregate or multiple.  After the dissection, each group will categorize their sample as one of the types of fruit and  identify the various structures of each fruit.  The students will carry out a microscopic study of the different stages of meiosis in the lily anther and ovulary which produce microsporangia (male spores) and megasporangia (female spores).  The module also includes a virtual/interactive flower dissection, a power point presentation and a flower and fruit Taboo game. 


Subject: Science (7), or Science (7)
Title: Modeling Meiosis and Gamete Formation
Description: The Modeling Meiosis and Gamete Formation Module includes hands-on and inquiry-based activities.  Using yarn and pop beads, students will simulate the changes in chromosome pairs as they move through the various stages of meiosis.  The students will use Play Dough to model the formation of the sperm and egg cells and to denote the differences in cytokinesis and explain the reasoning for the differences. 


Subject: Science (7), or Science (7)
Title: Osmosis and Diffusion Lab
Description: Osmosis and Diffusion lab includes hands-on inquiry based activities.  The module is divided into three parts:  a. teacher demonstration of osmosis and diffusion using Gummy Bears, salt, celery, food coloring, and hot and cold water; b. hands-on student labs to demonstrate diffusion using various concentrations of corn starch and Lugol’s solution; c. hands-on student lab to demonstrate osmosis using dialysis tubing, sucrose solution, corn starch, phenolphthalein, ammonia, vinegar, and universal indicator solution.


Subject: Science (7), or Science (7), or Technology Education (6 - 8)
Title: The Human Body Inc.: What's an Arm and a Leg Worth?
Description: In this technology-based project, students will take on the role of a legal defense team and prepare the court defense for a body organ that is currently an employee of Human Body Inc.. Due to recent cost increases, the Human Body has had to fire workers. Assuming the role as lawyer, students' responsibilities are to conduct research, collect and analyze material, and produce an informative and explanatory multimedia presentation (PowerPoint, PhotoStory, Keynote, etc.) defending their body organ's position in the company and what would happen if their client were fired. In addition, they are to create a brochure, highlighting the trendy spots, the exciting activities, etc., of the body system in which the organ works, convincing the corporation of the importance in keeping their client. The students will present their case at an administrative hearing to the Human Body Committee (whole class), the corporate group who will decide the ultimate fate of the body organ.

Title: Coping with Changes      Add Bookmark
Description: The purpose of this Science NetLinks lesson is to understand how the nervous system allows us to learn, remember, and cope with changes in the environment. The activities in this lesson introduce the nervous system, both in parts and as a whole. By learning about the whole system, students understand that the brain, spinal cord, and nerve cells are at the root of all other body functions.

Title: Nearsightedness      Add Bookmark
Description: In this Science NetLinks lesson, students develop an understanding of why scientific investigations may yield varying results. Students examine the nature of scientific research in the context of research pertaining to myopia--or nearsightedness--a common condition that normally first appears in school-age children. Myopia provides an interesting context in which to examine the scientific world view, because though it is a very common condition, it is a topic about which there is still some scientific debate.

Title: Sanitation and Human Health      Add Bookmark
Description: The purpose of this Science NetLinks lesson is to develop an understanding of the impact of improved sanitation on human health. In this lesson, students learn something about the ways that sanitation technology has helped people by examining the history of sanitation in the context of disease outbreaks and comparing the quality of life in those times to that of today. By the end of this lesson, students should recognize that advances in health and human life expectancy have resulted in large part because of technologies that we now take for granted, such as modern waste-disposal, sanitary food handling, and refrigeration.
