Every form of life that we know of requires carbon. This Mini Lecture introduces to the chemically most versatile element, essential to all life, both as an energy source and as building stock. Lecture snippets of the chemists Robert Curl und Karl Ziegler explain the structure of the symmetric C60 molecule as well as the Ziegler-Natta process used to make polymers.

Capillary Action in Sand
Read the Fine Print
Educational Use
Rating
0.0 stars

As part of a (hypothetical) challenge to help a city find the most affordable and environmentally friendly way to clean up an oil spill, students design and conduct controlled experiments to quantify capillary action in sand. Like engineers and entrepreneurs, student teams use affordable materials to design and construct models to measure the rate of capillary action in four types of sand: coarse, medium, fine and mixed. After observing and learning from a teacher-conducted capillary tube demonstration, teams are given a selection of possible materials and a budget to work within as they design their own experimental setups. After the construction of their designs, they take measurements to quantify the rate of capillary action, create graphs to analyze the data, and make concluding recommendations. Groups compare data and discuss as a class the pros and cons of their designs. Pre- and post-evaluations and two worksheets are provided.

We are now going to delve into the heart of chemistry. We learn ways of representing molecules and how molecules react. To do this, we'll even think about "how many" of a molecule we have using a quantity called a "mole".

Elements and Atoms: The Building Blocks of Matter
Unrestricted Use

Rating
0.0 stars

This OER discusses matter, elements, compounds, atoms, and the subatomic particles succinctly. It would be most effective if used as a supplement to a text, another website, some type of multimedia, and/or as a review on the subject. There are additional links and resources to support advance instructions and learning. The idea that students are able to work independently to improve their learning is an advantage to using this OER as an augmentation. It contains an assessment with hidden answers, which supports a check for mastery; it also requires some critical thinking skills.

This six-day lesson provides students with an introduction to the importance of energy in their lives and the need to consider how and why we consume the energy we do. The lesson includes activities to engage students in general energy issues, including playing an award-winning Energy Choices board game, and an optional graphing activity that provides experience with MS Excel graphing and perspectives on how we use energy and how much energy we use.

Gas Model

CC BY-NC-SA
Rating
0.0 stars

This highly visual model demonstrates the atomic theory of matter which states that a gas is made up of tiny particles of atoms that are in constant motion, smashing into each other. Balls, representing molecules, move within a cage container to simulate this phenomenon. A hair dryer provides the heat to simulate the heating and cooling of gas: the faster the balls are moving, the hotter the gas. Learners observe how the balls move at a slower rate at lower "temperatures."

General Chemistry: Principles, Patterns, and Applications
Conditional Remix & Share Permitted
CC BY-NC-SA
Rating
0.0 stars

The overall goal of the authors with General Chemistry: Principles, Patterns, and Applications was to produce a text that introduces the students to the relevance and excitement of chemistry.Although much of first-year chemistry is taught as a service course, Bruce and Patricia feel there is no reason that the intrinsic excitement and potential of chemistry cannot be the focal point of the text and the course. So, they emphasize the positive aspects of chemistry and its relationship to studentsŐ lives, which requires bringing in applications early and often. In addition, the authors feel that many first year chemistry students have an enthusiasm for biologically and medically relevant topics, so they use an integrated approach in their text that includes explicit discussions of biological and environmental applications of chemistry.

Gumdrop Atoms

Students use gumdrops and toothpicks to make lithium atom models. Using these models, they investigate the makeup of atoms, including their relative size. Students are then asked to form molecules out of atoms, much in the same way they constructed atoms out of the particles that atoms are made of. Students also practice adding and subtracting electrons from an atom and determining the overall charges on atoms.

In this classic hands-on activity, learners estimate the length of a molecule by floating a fatty acid (oleic acid) on water. This lab asks learners to record measurements and make calculations related to volume, diameter, area, and height. Learners also convert meters into nanometers. Includes teacher and student worksheets but lacks in depth procedure information. The author suggests educators search the web for more complete lab instructions.
