Do Plants Eat?
Through a teacher-led discussion, students realize that the food energy plants obtain comes from sunlight via the plant process of photosynthesis. They learn what photosynthesis is, at an age-appropriate level of detail and vocabulary, and then begin to question how we know that photosynthesis occurs, if we can't see it happening. Elodea is a common water plant that students can use to directly observe evidence of photosynthesis. When Elodea is placed in a glass beaker near a good light source,
Getting to the Point
In this lesson, students learn how to determine location by triangulation. We describe the process of triangulation and practice finding your location on a worksheet, in the classroom, and outdoors.
Students construct a rocket from a balloon propelled along a guide string. They use this model to learn about Newton's three laws of motion, examining the effect of different forces on the motion of the rocket.
Watt meters to measure energy consumption
Students use watt meters to measure the power required and calculate energy used from various electrical devices and household appliances.
Students make Moebius strips and use them to demonstrate the interconnectedness of an environment. They explore the natural cycles water, oxygen/carbon dioxide, carbon, nitrogen that exist within the environment.
Solving Energy Problems
The culminating energy project is introduced and the technical problem solving process is applied to get the students started on the project. By the end of the class, the students should have a good perspective on what they have already learned and what they still need to learn to complete the project.
Learning Light's Properties
Students learn the basic properties of light the concepts of light absorption, transmission, reflection and refraction, as well as the behavior of light during interference. Lecture information briefly addresses the electromagnetic spectrum and then provides more in-depth information on visible light. With this knowledge, students better understand lasers and are better prepared to design a security system for the mummified troll.
The difference between an architect and an engineer is sometimes confusing because their roles in building design can be similar. Students experience a bit of both professions by following a set of requirements and meeting given constraints as they create a model parking garage. They experience the engineering design process first-hand as they design, build and test their models. They draw a blueprint for their design, select the construction materials and budget their expenditures. They also te
How Much Heat Will It Hold?
Students relate thermal energy to heat capacity by comparing the heat capacities of different materials and graphing the change in temperature over time for a specific material. Students learn why heat capacity is an important property of thermal energy that engineers use in many applications.
Using a Dictionary
This language and communications skills resource is concerned with the use of a dictionary to look up the meaning of words and compare synonyms. It is suitable for pupils who are in the following categories - educationally/socially disadvantaged, learning difficulties, dyslexia, refugees, specific learning disabilities, hearing impairment,
Two Versions of Gravity: Newton and Einstein
Students explore the differences between Einstein and Newtonian gravity through an information exchange. Grades 11-12
Using Community Resources to Teach Genetics
In this online article, from the museum's Musings newsletter for educators, the Youth and Family Programs Director offers advice on how to integrate genetics learning into students' daily lives. The tips she gives are: make it simple find local or online resources check out the news use an interdisciplinary approach to ethical issues expose students to new career options remember that the best science generates more questions.
Cheat Sheet to Mastering Japanese #8 - Pop Quiz Time! Do You Know How To Test Your Skills?
We know, we know - if you wanted to take tests and quizzes, you’d go enroll in your local community college’s foreign language classes. But did you know that even as a self-studier, quizzing yourself will really bring out the best in your language abilities? And the best part about [...]
På onsdagen berättade Klartext att många personer med funktionshinder inte får den hjälp de behöver. Vi berättade att en del äldre i Malmö ska övervakas med kameror i sina sovrum. Programmet handlade också om de hemska fånglägren i Nordkorea som blir allt större.
The Law of Inertia: Newton's First Law
This NASA video segment explores how Newton's first law of motion applies to aerospace. An instructor at NASA's National Test Pilot School defines the law of inertia and then explains how the seatbelt in a jet provides an outside force to stop the inertia of the pilot. The instructor also discusses inertia experienced by humans while riding in the test vehicles for space travel in this three minute video. A good introduction.
Crocodiles in Love
With snout rubbing and bubble blowing, two saltwater crocodiles court one another. (02:26)
Indians processing salt, and demonstrations during the salt satyagraha, April 1930. This narrated video consists of vintage images of the time. Courtesy: GandhiServe Foundation Mahatma Gandhi. (01:31)
Dress Design Using Geometric Patterns
This 2:44 video shows Amy Williams explaining the design of certain dresses, created out of paper. These patterns consist of triangles, and the folds are simliar to the style of origami. This is an interview, but there are plenty of examples. Would make a good geometry class project using paper designs.
This video gives basic information about Rosh Ha'Shanah. It contains a lot of text and has some images accompanying it.
Investigating Greenland's Melting Glaciers
Scientists supported by environmental organisation Greenpeace find evidence that Greenland's glacier are melting faster than expected because of the influx of subtropic waters to the Arctic. (02:56)
