Students use a simple pH indicator to measure how much CO2 is produced during respiration, at rest and after exercising. They begin by comparing some common household solutions in order to determine the color change of the indicator. They review the concepts of pH and respiration and extend their knowledge to measuring the effectiveness of bioremediation in the environment.

Conserving Waterlogged Wood
Unrestricted Use
CC BY
Rating
0.0 stars

This video resource is presented as a real-world application of chemistry in the field of conservation archaeology. Conservator, Francis Lukezic, walks through the conservation practices for waterlogged archaeological wood and explains the chemical and cellular processes at work. Use to support Maryland/NGSS for Grades 5, MS, and HS. For 5-PS1-1 and MS-PS1-1, have students watch or perform the paper clip demonstration and discuss how the hydrogen bonding of water allows this then is disrupted by the soap; have students develop diagrams explaining the phenomenon of surface tension on the molecular level. For HS-PS2-6, have students watch or perform the sponge demonstration and discuss how the molecular structure of the wood makes it vulnerable to becoming waterlogged then brainstorm materials that are more resilient to water and discuss the uses of the materials. For interdisciplinary connections to geography and history, have students research why Maryland archaeologists do or do not discover the materials brainstormed instead of wood. If you evaluate or use this resource, please respond to this short (4 question) survey bit.ly/3DhRumA

Engineering and the Periodic Table

Rating
0.0 stars

Students learn about the periodic table and how pervasive the elements are in our daily lives. After reviewing the table organization and facts about the first 20 elements, they play an element identification game. They also learn that engineers incorporate these elements into the design of new products and processes. Acting as computer and animation engineers, students creatively express their new knowledge by creating a superhero character based on of the elements they now know so well. They will then pair with another superhero and create a dynamic duo out of the two elements, which will represent a molecule.

Rating
0.0 stars

This course focuses on the fundamentals of structure, energetics, and bonding that underpin materials science. It is the introductory lecture class for sophomore students in Materials Science and Engineering, taken with 3.014 and 3.016 to create a unified introduction to the subject. Topics include: an introduction to thermodynamic functions and laws governing equilibrium properties, relating macroscopic behavior to atomistic and molecular models of materials; the role of electronic bonding in determining the energy, structure, and stability of materials; quantum mechanical descriptions of interacting electrons and atoms; materials phenomena, such as heat capacities, phase transformations, and multiphase equilibria to chemical reactions and magnetism; symmetry properties of molecules and solids; structure of complex, disordered, and amorphous materials; tensors and constraints on physical properties imposed by symmetry; and determination of structure through diffraction. Real-world applications include engineered alloys, electronic and magnetic materials, ionic and network solids, polymers, and biomaterials.
This course is a core subject in MIT’s undergraduate Energy Studies Minor. This Institute-wide program complements the deep expertise obtained in any major with a broad understanding of the interlinked realms of science, technology, and social sciences as they relate to energy and associated environmental challenges.

Hydrogen

Rating
0.0 stars

Hydrogen is a versatile energy currency that can be produced from fossil fuels or water and that also occurs naturally in rocks underground. Hydrogen has very low energy density by volume but is extremely energy dense by weight. Hydrogen shows promise as a clean fuel for heavy-duty transportation, steel-making, heating, and energy storage. Today, the vast majority of produced hydrogen is created from fossil fuels. Renewable hydrogen can be created through electrolysis, the process of using electricity to create hydrogen from water, but it is more expensive.

Hydrogen-Oxygen Reaction Lab

Educational Use
Rating
0.0 stars

This lab exercise exposes students to a potentially new alternative energy source hydrogen gas. Student teams are given a hydrogen generator and an oxygen generator. They balance the chemical equation for the combustion of hydrogen gas in the presence of oxygen. Then they analyze what the equation really means. Two hypotheses are given, based on what one might predict upon analyzing the chemical equation. Once students have thought about the process, they are walked through the experiment and shown how to collect the gas in different ratios. By trial and error, students determine the ideal combustion ratio. For both volume of explosion and kick generated by explosion, they qualitatively record results on a 0-4 scale. Then, students evaluate their collected results to see if the hypotheses were correct and how their results match the theoretical equation. Students learn that while hydrogen will most commonly be used for fuel cells (no combustion situation), it has been used in rocket engines (for which a tremendous combustion occurs).

Inorganic chemistry is concerned with the properties and reactivity of all chemical elements. Advanced interests focus on understanding the role of metals in biology and the environment, the design and properties of materials for energy and information technology, fundamental studies on the reactivity of main group and transition elements, and nanotechnology. Synthetic efforts are directed at hydrogen storage materials and thermoelectrics, catalysts for solar hydrogen generation, fullerenes and metal porphyrins, metal clusters and compounds with element-element bonds, as well as nanowires and nanoparticles.

Through this lab, students are introduced to energy sciences as they explore redox reactions and how hydrogen fuel cells turn the energy released when hydrogen and oxygen are combined into electrical energy that can be read on a standard multimeter. They learn about the energy stored in bonds and how, by controlling the reaction, this energy can be turned into more or less useful forms.
