Cycads (Cycas revoluta)
Cycads look like palms but are not among the flowering plants. Cycad seeds develop on specialized leaves. These leaves pack together to form a cone.
In this activity, students investigate how different riparian ground covers, such as grass and pavement, affect river flooding. They learn about permeable and impermeable materials through the measurement how much water is absorbed by several different household materials in a model riverbed. Students use what they learn to make recommendations for engineers developing permeable pavement. Also, they consider several different limitations for design in the context of a small community.
Household energy audit
Students review the electrical appliances used at home and estimate the energy used for each. The results can help to show the energy hogs that could benefit from conservation or improved efficiency.
Learn About Triceratops Learn Abou
The name Triceratops means "three horned face". This video gives great facts about the Triceratops. Some of the facts include size (weight and height), eating habits, skull size, frill, predators, fossils, and herding habits. This is a great resource to work in conjunction with non-fiction texts on this subject. Students will enjoy this fun, informative video. (3:09)
'City, Art, Motion: Rethinking the "Now" in Johannesburg' (Annual Lecture 2011)
Sarah Nuttal, Research Professor, Department of English, University of Stellenbosch, gives the first 2011 African Studies Annual Lecture on 26th May 2011.
4.2 Naturalism and reductive explanation
What is consciousness? How does the brain generate consciousness and how can a science of the mind describe and explain it adequately? This unit will introduce you to the slippery phenomenon that is consciousness, as well as some of the difficulties consciousness presents to science and philosophy.
Directed in 1971 by Robert Alan Weiss for the Department of Chemistry of Stanford University and imprinted with the "free love" aura of the period, this short film continues to be shown in biology class today. It has since spawn a series of similar funny attempts at vulgarizing protein synthesis. Narrated by Paul Berg, 1980 Nobel prize for Chemistry.

PediNeuroLogic Exam: 6 Month Old: Normal: Behavior
The baby is sitting comfortably in his mother's lap. He is socially aware, inquisitive and readily responds to visual objects and sounds. He smiles, laughs, and jabbers. At this age a baby will start to make repetitive speech sounds that are nonspecific such as da, ma, or ba. A neuroscience tutorial focusing on those aspects of the pediatric neurological examination that are unique to the child's nervous system, with an emphasis on important neurodevelopmental milestones.
PediNeuroLogic Exam: Developmental Anatomy - Neuronal Growth and Organization
By 36 weeks gestation, the process of neuronal proliferation is nearly complete. Although there is some limited proliferation of neurons throughout life, their contribution to brain growth is negligible. Growth of the individual neurons plus the elaboration and proliferation of dendritic and axonal processes and connections is responsible for most of the brain's growth. The diameter of a neuroblast is 5 microns while a mature neuron can measure 50 microns, a 1,000-fold increase in cell volume. I
Chlorine Nitrate over the Arctic from CLAES (2-12-93 - 3-16-93)
Key to understanding the chlorine chemistry in the polar stratosphere is the measurement of polar stratospheric clouds, chlorine monoxide, and the reservoir gas chlorine nitrate. Chlorine nitrate has been measured by the Cryogen Limb Array Etalon Spectrometer, CLAES. CLAES makes measurements by looking at infrared emission from cloud particles and trace gases. CLAES measurements help to show that the polar stratospheric clouds which form in the cold Arctic stratosphere have converted most of the

Buildings bear silent witness to the history that happens inside them. Conservator Matt Webster makes sure structures live to tell their tales.
What's a Terrarium and How does it Work?
A short segment explaining what a terrarium is and how it works. Produced for students and is suitable for elementary and older.
(This is an Emmy award-winning series of instructional programs that introduces students in grades 3-5 to NASA and integrates mathematics, science, and technology through the use of Problem-Based Learning (PBL), scientific inquiry, and the scientific method. The series seeks to motivate students to become critical thinkers and active problem solvers.)
