Chemistry Unit One
The module contains the following levels: Metal Compounds Alcohols Periodic Table and atomic structure Acid base reactions - Group 2 elements Energy Change
Test your knowledge about cell differentiation, cell function and tissue culture.
Explore the origin of energy bands in crystals of atoms. The structure of these bands determines how materials conduct electricity. Teacher's guide available.
Circuit Construction Kit (AC+DC)
This new version of the CCK adds capacitors, inductors and AC voltage sources to your toolbox! Now you can graph the current and voltage as a function of time.
Kamchatka: Siberia's Forbidden Wilderness
These lessons are designed for earth science and biology students in middle and high school classrooms, though extension suggestions for older and younger students will allow you to adapt each lesson for younger and older audiences. The lessons are designed to complement the Living Edens: Kamchatka program; each lesson will indicate clips from the program that focus on the topic at hand, though the lessons function equally well as stand-alone content.
Tracing Genetic Ancestry Using DNA Microarrays
In this lesson students will read and discuss an article about genetic ancestry and genetic ancestry testing. 2. Apply knowledge of DNA and heredity to understand DNA microarrays, and concepts of genetic mutation and ancestry tracking. 3. Mimic the function of a DNA microarray used for genetic ancestry analysis by completing a paper-and-pencil activity. 4. Discuss the ethics of genetic testing in medical research.
Fourier Sine Series
The Fourier sine series model displays the sine series expansion coefficients of an arbitrary function on the interval [0, 2?].
This sequence presents the basic principles of bone and joint structure and function and to review many of the disease entities related to this system and to the soft tissue as well. General clinical approaches to diagnosis and treatment will be discussed as well.
In this activity, students can select values for quadratic function coefficients, plot and explore multiple functions.
Population: Age Structure
One of the primary tools that demographers use to understand population is the age structure diagram, a graphic representation that shows the distribution by ages of females and males within a certain population.
This lesson provides an overview of basic atomic structure and the concept of radioactive decay. Topics include the particles that make up an atom, binding forces, and the concept of isotopes. There is also discussion of decay methods and half-life.
This exercise is intended to reinforce the importance of Earth's atmosphere to living organisms. Topics include our bodies' interactions with the atmosphere; its composition and structure; and natural changes in the atmosphere (weather).
In this Design Challenge, families and friends work together to design the tallest structure that they can, using only the materials provided.
Social Structure-Personality: What is the Relationship Between Social Class and Child-rearing Values
The sociologist, Melvin Kohn, argued that people's locations in social structures, particularly the occupational structure, influenced the values they would stress for their children because variations in structural locations exposed them to different experiences.
Predictors of Family Structure
This exercise looks at race and family income as predictors of family structure. Students will test and evaluate hypotheses, learning how to work with control variables and bivariate tables.
Race and Changing Household Structure
The textbook for this course discusses cross-cultural variations in household structure, as well as changes across time in household structure in the United States. The purpose of this exercise is to examine variations in household structure in the United States according to race and historical period.
Wiki in the Classroom
It is common knowledge that Wikipedia--for all its convenience--is an unreliable source of information. It is impossible to verify authorship, as anyone with internet access is able to edit any entries on the website. However, the Wiki structure is an excellent means to provide and share information. ...
The Internet is a vast network that connects many smaller groups of linked computer networks, on and through which information is stored and transmitted. The "interconnected" character of the Internet is one of the things that makes it so popular and powerful in facilitating communication and electronic commerce. However, "interconnectivity" has also given rise to increasing legal controversy and turmoil. Various methods of enhancing or exploiting the web-like structure of the Internet have been
Multiplication tables - Structured Drill Video
In this video learn how to drill multiplication tables
effectively - not with random drill, but with a three-step approach that
keeps the drilling in a context, in a structure. The three steps are:
1) Skip counting pattern using a number line; 2) the actual
multiplication tables practice; and 3) practicing backwards.
Excel Frequency in Chart
This video introduces how to use Excel to sort data, perform the frequency function, and present data in line chart.
