Create a Pinhole Camera
In this activity, students construct their own pinhole camera to observe the behavior of light.
A Spectral Mystery
Students use the spectrograph from the “Building a Fancy Spectrograph” activity to gather data about light sources. Using their data, they make comparisons between different light sources and make conjectures about the composition of a mystery light source.
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.
Pictures Please – Traveling Light
In this lesson, students learn that light travels in a straight line from a light source and that ray diagrams help us understand how an image will be created by a lens. In the accompanying activity, students explore the concepts behind the workings of a pinhole camera.
The Artificial Bicep
Students learn more about how muscles work and how biomedical engineers can help keep the muscular system healthy. Following the engineering design process, they create their own biomedical device to aid in the recovery of a strained bicep. They discover the importance of rest to muscle recovery and that muscles (just like engineers!) work together to achieve a common goal.
Let Your Ears do the Walking
In the previous lesson, students learned about the issue of bycatching by fisheries and how it affects marine habitats. Dolphins are one of the main species affected by bycatching. Dolphins use echolocation to identify the location of objects in the water, but they have difficulty identifying nets, and thus can be caught accidentally. Students will learn how echolocation works, why certain animals use it to determine the size, shape, and distance of objects, and how humans can potentially take a
How to be a Great Navigator!
In this lesson, students will learn how great navigators of the past stayed on course — that is, the historical methods of navigation. The concepts of dead reckoning and celestial navigation are discussed.
Marine animal tracking
The following lesson is an introduction to the ideas and implications of animal tracking. Animal tracking is a useful method used within science and commercial industries. For instance, when planning the development coastal areas, animal presence and movement should be taken into consideration. The lesson engages students in an activity to monitor animal foraging behavior on a spatial scale. The students will break into groups and track each other’s movements as they move through a pre-determi
What Trickles Down?
Permeability is the degree to which water or other liquids are able to flow through a material. Different substances such as soil, gravel, sand, and asphalt have varying levels of permeability. In this activity, students will explore different levels of permeability and compare the permeabilities of several different materials. They will also be introduced to the basic concepts of building design, landscape architecture, and environmental pollutant transport. As an extension activity, they will
Graphing the West Corridor Data
This activity introduces students to using graphical analysis of data to analyze flaws in a transit system's design. Students will evaluate factors such as ride time, wait time, and percentage of capacity used in a train. This activity requires the use of the FasTracks Living Lab.
The objective of Lesson 2 is for student teams to determine the size of the caverns. Lesson two has student teams measure their classroom to determine area and volume; determine how many people could comfortably sleep in their classroom; scale this number up to find the required area for all Alabraskans. The lesson provides a good application of area and volume concepts. Students also perform math conversions between feet, meters, miles and kilometers.
Bulbs & Batteries in a Row
Everyday we are surrounded by circuits that use “in parallel” and “in series” circuitry. Complicated circuits designed by engineers are composed of many simpler parallel and series circuits. During this activity, students build a simple series circuit and discover the properties associated with series circuits.
National Park Service-Mississippi National River and Recreation Area
The Mississippi National River and Recreation Area includes 72 miles of the Mississippi River stretching from the cities of Dayton and Ramsey, Minnesota to just downstream of Hastings, Minnesota. The diverse stretch of the river flowing through the park consists of numerous natural, historic, recreational and cultural resources of national significance. This is a great resource for teaching about US Geography and the importance of the Mississippi River. Content is appropriate for upper elementar
U.S. says Gaddafi weakened but not defeated
U.S. military officials say Gaddafi is not close to a military breaking point even though coalition strikes have seriously degraded his fighting power. Deborah Lutterbeck reports.
7.1.1 Using the keyboard
Frightened of the internet? This unit will help you make effective use of the internet, giving you the basic skills required for using web-based resources. Useful tricks and tips are provided as well as information on web browsers, the main features of a browser window, how to look at websites, using hyperlinks, searching for information on the internet, copying text, avoiding computer viruses, and using PDFs.
Jane Edna Hunter and Clemson
Rhondda Thomas, professor of African American literature and early American literature at Clemson University, discusses Jane Edna Hunter, the founder of the Phillis Wheatley Association, who grew up in Pendleton, SC at Woodburn Plantation.
How it's Made - Lithium Ion Batteries
Batteries are examples of stored energy, chemical potential energy to be exact. But how are batteries made and what is inside? This is a segment from the Discovery Channel series "How it's Made" on lithium ion batteries.(05:36)
Solving Division Problems Using Coins
When working with coins, the value of each coin and the
total number of coins represent the small numbers in a number family and the big number is the total value of all of the coins. Students use
this knowledge to write number families for several word and coin
Dividing Juice with Curious George
The children have to figure out a way to divide three bottles of juice evenly between four children. They use a measuring cup to pour the juice and divide by four. This video could be used for a lesson on division or a lesson on measuring.
Irish banks' 25 bln euro hole?
Ireland is set to reveal up to a 25 billion euro hole in its banks' capital and a radical restructuring of the sector as it releases stress results in a last ditch bid to calm nervous markets.
