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.

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

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.

How Big?
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.

PediNeuroLogic Exam: 6 Month Old: Normal: Postural Reflexes - Parachute
The parachute reflex is the last of the postural reflexes to develop. It usually appears at 8 to 9 months of age. When the baby is turned face down towards the mat, the arms will extend as if the baby is trying to catch himself. Prior to developing this reflex, the baby will actually bring the arms back to the plane of the body and away from the mat. A neuroscience tutorial focusing on those aspects of the pediatric neurological examination that are unique to the child's nervous system, with an

1.3.5 Histograms and scatterplots: summary
This Unit will introduce you to a number of ways of representing data graphically and of summarising data numerically. You will learn the uses for pie charts, bar charts, histograms and scatterplots. You will also be introduced to various ways of summarising data and methods for assessing location and dispersion.

5.3 Global warming
To be able to understand the importance of the environment for our health, we need to know a little about the interdependence between environment and humankind. This unit will look at interactions between plants, animals and the physical and chemical environment, as well as considering ways in which humans have altered, and are altering this environment. These changes have health implications that are not always immediately obvious. Frequently, we initiate changes that are going to have their ef
