In this activity, students will learn how to read a topographical map and how to triangulate with just a map. True triangulation requires both a map and compass, but to simplify the activity and make it possible indoors, the compass information is given. Students will practice converting a compass measurement to a protractor measurement, as well as reverse a bearing direction (i.e., if they know a tree’s bearing is 100 degrees from you, they can determine what bearing they are from the tree).
In this activity, students learn how engineers use solar energy to heat buildings by investigating the thermal storage properties of some common materials: sand, salt, water and shredded paper. Students then evaluate the usefulness of each material as a thermal storage material to be used as the thermal mass in a passive solar building.
Graphing the Rainbow
Students are introduced to different ways of displaying visual spectra, including colored “barcode” spectra, like those produced by a diffraction grating, and line plots displaying intensity versus color, or wavelength. Students learn that a diffraction grating acts like a prism, bending light into its component colors.
Energy Storage Derby and Proposal
In Activity 5, as part of the Going Public step students demonstrate their knowledge of how potential energy may be transferred into kinetic energy. Students design, build, and test prototypes of vehicles that transfer various types of potential energy into motion.
The Need for Shelter
In this lesson, the students will build a shelter in order to protect themselves from the rain. After the shelters are built, the class will perform durability and water proof testing on the shelters.
Biodomes Engineering Design Project: Lessons 2-6
In this multi-day activity, students explore environments, ecosystems, energy flow and organism interactions by creating a scale model biodome, following the steps of the engineering design process. The Procedure section provides activity instructions for Biodomes unit, lessons 2-6, as students work through Parts 1-6 to develop their model biodome. Subjects include energy flow and food chains, basic needs of plants and animals, and the importance of decomposers. Students consider why a solid und
Students learn about tsunamis, discovering what causes them and what makes them so dangerous. They learn that engineers design detection and warning equipment, as well as structures that that can survive the strong wave forces. In a hands-on activity, students use a table-top-sized tsunami generator to observe the formation and devastation of a tsunami. They see how a tsunami moves across the ocean and what happens when it reaches a coastline. They make villages of model houses to test how diffe
Heredity Mix ’n Match
Students randomly select jelly beans (or other candy) that represent genes for several human traits such as tongue-rolling ability and eye color. Then, working in pairs (preferably of mixed gender), students randomly choose new pairs of jelly beans from those corresponding to their own genotypes. The new pairs are placed on toothpicks to represent the chromosomes of the couple’s offspring. Finally, students compare genotypes and phenotypes of parents and offspring for all the “couples” in
Designing Medical Devices for the Ear
Students are introduced to engineering, and more specifically, to biomedical engineering and the engineering design process through a short lecture and interactive, hands-on activity (approximately 30 minutes long), where students design their own medical device for retrieving foreign bodies from the ear canal. In this lesson, the teacher first reviews the basics of ear anatomy then discusses how ear infections occur and how they are treated. Following antibiotic treatment, the most common treat
Understanding Rational Numbers and Proportions
The three activities in this investigation center on situations involving rational numbers and proportions that students encounter at a bakery. These activities involve several important concepts of rational numbers and proportions, including partitioning a unit into equal parts, the quotient interpretation of fractions, the area model of fractions, determining fractional parts of a unit not cut into equal-sized pieces, and equivalence.

ADHD and the Brain AnswersTV.com, video is hosted by Dr. Gerald Chodak. Video gives the history of ADHD, what happens in the brain, and what is often used to treat ADHD. ADHD is a common behavioral disorder and occurs before the age of seven. What they do know is that the occurrence of ADHD is tied to biological factors such as the size and density of various brain structures and the chemical reactions that take place in the brains.

South Island Wren--An Overview
This short video gives excellent real life, close up footage of a South Island Wren. The South Island wren is a small but robust alpine bird with a very short tail, rounded wings, and long legs and toes. While the male’s plumage is a dull green colour above, grey-brown below and yellow on the flanks, the female is more olive-brown in colour. This charming bird has an unusual habit of vigorously bobbing up and down. This is a great resource to help build background knowledge and to hel
ArchiDATA: A Hypermedia Tool for Architecture
Design is a cooperative activity at several levels. At one level, clients, architects, financiers, and construction engineers and contractors, all play important roles in creating the design for the building. At another level, the design team may contain architects, interior and landscape designers, lighting experts, heating, ventilation, and air-conditioning experts, etc. At a third level, individual architects cooperate with computer-based design tools in creating portions of a complex design.
Lecture 07 - 10/14/2010
Inequalities and Absolute Value Concepts -- "Piecewise Functions" and Absolute Value
This module introduces piecewise functions for the purpose of understanding absolute value equations.
Capture of Dwarf Seahorses for Aquarium Trade
This short video gives excellent, real life footage of how dwarf seahorses are caught for aquarium trade. Students will enjoy seeing the large nets dragging the bottom of the ocean. This is a great resource to help build background knowledge and to help make real world connections between nature and the classroom. (Less Than 2 Minutes)
Lesson #047, Tuesday You make a sentence negative by placing 'non' directly before the verb, and when responding negatively to a question, you must say 'no' as well as placing 'non' before the verb.
