This textbook is a reference text for General Chemistry, including the major concepts and ideas of chemical science, and a look at some of the major currents of modern Chemistry
Will a grape float in oil? Will a metal nut sink in corn syrup? Watch as the ZOOM cast tests the buoyancy of a variety of liquids and objects.
A magician pours milk into a glass, but when he turns the glass upside down, nothing comes out. How does he do it? Discover the science behind the magic in this video adapted from the American Society of Mechanical Engineers.
Classification activities that will lead students from simple sorting of familiar objects to classifying materials into liquids, gases, and solids.
The students will be able to define solids and liquids from their prior knowledge. The students will be able to verbalize the differences between solids and liquids? Observe, communicate and question when things aren't what they appear to be. Is Oobleck a solid or liquid? The answer is that it is both. Have the students come up with their own answers and to communicate their findings. The students will understand the difference between a non-Newtonian fluid and a liquid or a solid.
A molecular approach to biology must develop in students an understanding of molecules, their interactions and the consequences of these interactions. Biological phenomenon now more than ever rely on chemical and physical principles for molecular explanations of the phenomenon. We have selected 10 physical-chemical principles that underlie many biological processes: we call them "Molecular Stepping Stones." Below are links to entry level model-based activities for the Stepping Stones.
This 10-minute video lesson considers what a fluid is. It looks at the difference between liquids and gasses (both fluids). [Physics playlist: Lesson 94 of 164].
This 10-minute video lesson on fluids looks at pressure and Pascal's Principal. [Physics playlist: Lesson 95 of 164].
This 10-minute video lesson presents a couple of problems involving Archimedes' principle and buoyant forces. [Physics playlist: Lesson 99 of 164].
This is an oceanography education journal consisting of current oceanography research conducted at NASA by NASA, NOAA, and university researchers and educators. This journal is a collection of articles, classroom activities, readings, teacher/student questions, imagery and much more designed for the grade 9-12 biology/environmental/earth science classroom. There is nothing out there like it and since we do a great deal of oceanographical research at Goddard Space Flight Center and the Wallops Flight Facility, we thought who better to put this together then our Hydrospheric and Biospheric Sciences Laboratory. We also have an accompanying web site that will eventually contain all the journal information, as well as future instrument data that can be scaled to the university level.
Eight questions to test your scientific knowledge of solids, liquids and gases
Thermodynamics is the study of energy and its transfers though work. This course will focus on the fundamentals of thermodynamics, including the First and Second Laws, thermodynamic properties, ideal gases, and equations of state. Upon successful completion of this course, the student will be able to: Identify and use units and notations in thermodynamics; State and illustrate the first and second laws of thermodynamics; Identify and explain the concepts of entropy, enthalpy, specific energy, reversibility, and irreversibility; Apply the first and second laws of thermodynamics to formulate and solve engineering problems for (i) closed systems, (ii) open systems under steady-state and transient conditions, and (iii) power cycles; Use thermodynamic tables, charts, and equation of state (e.g. the ideal gas law) to obtain appropriate property data to solve thermodynamics problems.
