The Solar Constant - Faculae vs. Sunspots
Three views of the Sun showing different levels of solar activity. The color table has been altered to enhance the appearance of the faculae (white regions) which are hotter than sunspots (red-black regions) and whose greater total area contribute to increasing the solar flux reaching the Earth.
Nimbus 7 Satellite
Visitors can view this image of the Nimbus 7 satellite, which has been used to measure ozone levels as part of the TOMS (Total Ozone Mapping Spectrometer) program.
Touch the Sun
Investigate the Sun with scientific instruments your students design and build in the classroom using inexpensive, everyday materials. Precision in construction and measurement are emphasized, as well as re-design to improve the quality of data. Activity theme areas include instrumentation, observation, ...
Taking Measure of the Universe
This poster with classroom activities is related to NASA-s Space Interferometry Mission. It introduces measurement and scale using hands-on activities.
Functions of 2 Variables: Partial Derivatives
Brandeis hosts several pages demonstrating the involvement of calculus in biology. This site gives a short explanation of the partial derivative of two variables, using illustrations and various levels of magnification to demonstrate. This resource is part of the Teaching Quantitative Skills in the ...
Media Literacy Lessons for ESOL Learners
Drawing on key media literacy concepts and strategies, these five media literacy lesson plans are designed for ESOL students and show how media literacy can enrich the ESOL curriculum. The lessons are appropriate for different levels of student competence in English and can be adapted to suit different student groups
Statistics in Psychosocial Research: Measurement
Presents quantitative approaches to measurement in the psychological and social sciences. Topics include the principles of psychometrics, including reliability and validity; the statistical basis for latent variable analysis, including exploratory and confirmatory factor analysis and latent class analysis; and item response theory. Draws examples from the social sciences, including stress and distress, social class and socioeconomic status, personality; consumer satisfaction, functional impairme
Project Zero's Studio Thinking Framework: Eight Habits of Mind
Project Zero's mission is to understand and enhance learning, thinking, and creativity in the arts, as well as humanistic and scientific disciplines, at the individual and institutional levels.
Optional Soil Infiltration Protocol
The purpose of this resource is to determine the rate at which water soaks into the ground. Students place two cans into the soil and add water to them to a depth of at least 5 cm. Students measure and record the time it takes the water level to drop a fixed 2 - 4 cm distance. Students repeat the measurement to determine how easily water moves vertically through the soil.
Instrument Construction, Site Selection and Set-Up
This resource provides guidance on site selection for the GLOBE Atmosphere data collection protocols. Instructions for building an instrument shelter, a snowboard, an ozone measurement station, and a wind direction instrument are included.
One Nation: Two Futures?
Since the mid-l970s, economic reforms have transformed China from one of the most egalitarian societies into one of the most unequal in the world. Wide disparities currently exist between the income levels of a relatively few rich and middle-class Chinese and their fellow citizens who number in the hundreds of millions. This "wealth gap" is particularly acute when one compares the incomes of urban and rural residents, between Chinese living in the interior of the country and those living in the
Earthquake Shaking and Damage
This homework exercise is designed to familiarize students with earthquake shaking, acceleration, intensity and hazards, including the quantitative measurement of these properties. Students analyze real earthquake data to determine the damage to their homes. By using students' own homes, they see the impacts of shaking, hazard, and intensity in a more personal, connected way. Learning goals, context for use, teaching tips, materials, assessment tips and related resources are provided.
Viscosity of the Mantle: Constraints from Post-glacial Rebound
In this lab, students determine the viscosity of a relatively viscous fluid by measuring the rate of rebound of a partially submerged object following a rapid decrease in its mass. This experiment is carried out in the context of an analysis of post-glacial rebound as a measurement of the viscosity ...
Star Library: What is the Shelf Life?
The Food and Drug Administration requires pharmaceutical companies to establish a shelf life for all new drug products through a stability analysis. This is done to ensure the quality of the drug taken by an individual is within established levels. The purpose of this out-of-class project or in-class ...
Revisiting "A Practical Guide to the Use of Cellular Slime Molds for Laboratory Exercises and Experi
Microbial eukaryotes in general, and cellular slime molds in particular, are well-suited for laboratory instruction in a variety of areas, including cellular biology, developmental biology, biochemistry, and population biology, and for a range of educational levels, such as introductory courses, upper-division ...
Strengthening Biology Teaching by Working with the Local School System
This object was developed to strengthen the level of collaboration between educators at all levels. It should be used to develop workshops, curricula, and projects with the intent of increasing the amount of communication between educators at different levels, and to promote a better exchange of information ...
Tracheid Length Measurement in Selected Conifer Species
This exercise illustrates the techniques for macerating wood and staining, mounting, and measuring tracheids. Mean tracheid length is different in different species of conifers; therefore, this laboratory can be expanded into a larger scale comparative measurement exercise.
Using Computer-Interfaced Physiological Measurement Systems in the Biology Laboratory
Students in General Biology perform two different laboratory exercises using computer-based physiological measurement systems to record data from student subjects. Using equipment from Intelitool, students measure resting and post-exercise ECGs, noting relative changes in each portion of the tracing. Then in a second exercise students measure lung volumes and capacities in resting and post-exercise subjects. Forced expiratory volumes (F.E.V.) for 1, 2, and 3 seconds are also measured. Notes for
How to Teach Subtraction (for youngest learners)
Teach the concept of subtraction in mathematics to students by incorporating physical items like markers. Convey the ideas of subtraction by using items like blocks or money with assistance from a seasoned math instructor. (01:20)
Unrelated Donor Bone Marrow Transplant for Sickle Cell Disease
By: mcgheek Jennifer Jaroscak, M.D., of MUSC Children's Hospital discusses bone marrow transplant (BMT) as a cure for patients with sickle cell disease. She describes a new reduced-intensity conditioning (RIC) regimen being trialed at MUSC for BMTs from well-matched unrelated donors in the SCURT study. RIC is safer for unrelated donor transplant because, unlike myeloablative BMTs, it suppresses but does not destroy the patient's bone marrow. Find out more about the SCURT study and reduced-intens
