This demonstration shows that similar-appearing lights can be distinctly different, suggesting that the light emitted is generated in different ways. It requires some advance preparation/setup by the teacher and three recommended sources of orange light, that can be purchased at a hardware or department store. Includes extensions and additional background information on light generation in a section on underlying principles. This resource is from PUMAS - Practical Uses of Math and Science - a collection of brief examples created by scientists and engineers showing how math and science topics taught in K-12 classes have real world applications.

Developed for second grade. Students will have the opportunity to see how a flower transports nutrients. In observing how the nutrients of a flower work their way up the stem and through the flower the students will be exposed to the various parts that create a flower and will have the opportunity to explore the parts and components of flowers.Biology In Elementary Schools is a Saint Michael's College student project. The teaching ideas on this page have been found, refined, and developed by students in a college-level course on the teaching of biology at the elementary level. Unless otherwise noted, the lesson plans have been tried at least once by students from our partner schools. This wiki has been established to share ideas about teaching biology in elementary schools. The motivation behind the creation of this page is twofold: 1. to provide an outlet for the teaching ideas of a group of college educators participating in a workshop-style course; 2. to provide a space where anyone else interested in this topic can place their ideas.

Pat Mora's poem "Echoes" demonstrates that our senses are powerful tools for literary analysis and comprehension as students use their senses to discover new ways to read and write.

This is an activity about the electromagnetic spectrum and how light is split into its component frequencies or colors. Using a diffraction grating, learners will observe four different light sources and sketch their spectra. This activity requires access to a sodium vapor or mercury vapor light and two neon signs of differing color, as well as diffraction grating material. This is Astronomy Activity 2 in the Space Update collection of activities.

Science Background:
When a metal or metal salt is burned, the input of thermal energy raises the electrons in the metal atom to a higher energy state. These electrons cannot remain in this excited state for too long and will emit energy in the form of light to return to the more stable, grounded state. It is this light we see when a metal atom is burned in a flame. Each metal has a characteristic flame colour which has been found to be useful in identifying minerals.
Materials: wood splints, Bunsen burner or BBQ lighter, solutions of strontium chloride (red), cupper (II) chloride (blue), copper (II) sulphate (green), calcium chloride (orange), potassium chloride (purple), and sodium carbonate (yellow).

The importance of family is prominent throughout the works, The vibrant colours represents the joy of life, it is meant to inspire hope, success, and happiness. These paintings are a tribute to my late mother who was my guide throughout my life, my late Grandmother for her strength in cultural beliefs and traditions, and my children for the inspiration they give me, Meegwetch.

Jason Logan is a Toronto-based artist, inkmaker and forager. He began his career as an illustrator in New York City and became interested in natural sources of pigment when his children were born. This documentary, organized by colour, takes us into Jason’s world, highlighting his curiosity, spirit of experimentation and creativity as he gathers natural and botanical materials throughout his travels and transforms them into ink, working like a mad scientist of sorts. For Jason, the creation of ink becomes a vehicle for connecting and relationship building with artists and other creatives from around the world. This mini lesson invites students to analyze where art materials come from by looking at the impact of drawing on the natural world to make ink. They will also explore concepts of permanence and ephemerality and can engage in geographically tracking the movement of Logan’s inks from place to place. The mini lesson also creates opportunities for students to research an individual artist represented in the film, and finally to work in pairs to make ink for one another.

Over the last four episodes, we’ve examined some of the stories that make up the idea of a “revolution” in knowledge-making in Europe. But we can’t understand this idea fully, without unpacking another one—the so called Age of Exploration. This encompasses a lot of events that happened from 1400 through the 1600s and were driven in part by new ideas about knowledge-making.

In which John Green teaches you about the changes wrought by contact between the Old World and the New. John does this by exploring the totally awesome history book "The Columbian Exchange" by Alfred Cosby, Jr. After Columbus "discovered" the Americas, European conquerors, traders, and settlers brought all manner of changes to the formerly isolated continents. Disease and invasive plant and animal species remade the New World, usually in negative ways. While native people, plants, and animals were being displaced in the Americas, the rest of the world was benefitting from American imports, especially foods like maize, tomatoes, potatoes, pineapple, blueberries, sweet potatoes, and manioc. Was the Columbian Exchange a net positive? It's debatable. So debate.

In which John Green teaches you about the beginning of the so-called Age of Discovery. You've probably heard of Christopher Columbus, who "discovered" America in 1492, but what about Vasco da Gama? How about Zheng He? Columbus gets a bad rap from many modern historians, but it turns out he was pretty important as far as the history of the world goes. That said, he wasn't the only pioneer plying the seas in the 1400s. In Portugal, Vasco da Gama was busy integrating Europe into the Indian Ocean Trade by sailing around Africa. Chinese admiral Zheng He was also traveling far and wide in the largest wooden ships ever built. Columbus, whether portrayed as hero or villain, is usually credited as the great sailor of the 15th century, but he definitely wasn't the only contender. What better way to settle this question than with a knock-down, drag-out, no holds barred, old-fashioned battle royal? We were going to make it a cage match, but welding is EXPENSIVE.

This art history video discussion examines the Column of Trajan, Carrara marble, completed 113 C.E., Rome. Dedicated to Emperor Trajan (Marcus Ulpius Nerva Traianus b. 53 , d. 117 C.E.) in honor of his victory over Dacia (now Romania) 101-02 and 105-06 C.E.

In the first part of this video introduction to combinatorics, we introduce factorial notation to efficiently describe the ways we can arrange distinguishable objects in a row. Next, we count the combinations of L objects that can be grabbed from a container of L + N total objects. Finally, we use the formula for combinations to derive the binomial theorem.

The primary purpose of this problem is to rewrite simple rational expressions in different forms to exhibit different aspects of the expression, in the context of a relevant real-world context (the fuel efficiency of of a car). Indeed, the given form of the combined fuel economy computation is useful for direct calculation, but if asked for an approximation, is not particularly helpful.

As a class, students use a low-cost air quality monitor (a rentable “Pod”) to measure the emissions from different vehicles. By applying the knowledge about combustion chemistry that they gain during the pre-activity reading (or lecture presentation, alternatively), students predict how the emissions from various vehicles will differ in terms of pollutants (CO2, VOCs and NO2), and explain why. After data collection, students examine the time series plots as a class—a chance to interpret the results and compare them to their predictions. Short online videos and a current event article help to highlight the real-world necessity of understanding and improving vehicle emissions. Numerous student handouts are provided. The activity content may be presented independently of its unit and without using an air quality monitor by analyzing provided sample data.
