Students investigate esters, make an ester and detect esters in natural foods and plants. In this esters lesson plan, students detect smells of hidden objects, produce an ester using peas, brown sugar and apple and demonstrate how to make a synthetic ester in the lab.
Students produce esters in the laboratory by combining different carboxylic acids with different alcohol. In this esterification lesson plan, students experiment with 3 carboxylic acids and 3 alcohols to produce 3 esters with fruit like odors. Students locate 5 grocery items with esters and identify each item and the alcohol and carboxylic acid used to produce each.
Middle schoolers become acquainted with natural foods and plants that contain an ester, which is synthesized in the laboratory. Afterwards, students explore how a scratch'n'sniff is encapsulated on a sticker.
Esters are the organic compounds that make the flavors in fruit. Chemguy explains the chemical reaction that creates an ester, how to name them, and how to draw their structures. This brief introduction can be embedded into your PowerPoint or Smart Board presentation or assigned as part of your chemistry class homework.
Students prepare artificial flavorings and fragrances. In this esters lesson, students combine an acid and an alcohol of choice to make an ester. Water is released and they produce an artificial flavoring or fragrance. They answer 4 questions about the ester they produced.
Students write proper laboratory reports as they prepare fragrant ester molecules. They develop the skill of naming esters.
Students investigate making esters in the lab. For this ester lesson plan, students mix 3 organic acids with 3 alcohols and a catalyst to form 3 different esters. Students identify the odors of each ester and write the formulas for the products. They answer 5 questions and draw the structural formulas for each esterification reaction.
In this ester worksheet, students mix organic acids with alcohols to produced esters and identify the products by the chemical reaction and the scent given off after the reaction occurs.
Nine action-packed organic chemistry exercises are contained in this mini-unit on carbon containing compounds. Examples include constructing models of alkanes, producing aromatic esters, and preparing pigments for paint and dyes. Chemistry scholars learn to write molecular formulas and draw structures for carbon compounds. Because of the complexity of the activities and level of skills required, this would not be recommended for first-year chemistry classes. It is, however, a superior resource!
“Humanscape No.65” by Melesia Casas and Ester Hernandez’s “Sun Maid Raisins” launch a study of how works of art can advocate for social change. After examining these two works and discussing the human rights issues raised, class members are encouraged to create their own advocacy graphic. Learning links, reflections, service opportunities, and worksheets are included in the richly detailed plan.
Students observe how esters are synthesized and recognize that esters have unpleasant odors. They record any noticeable changes in reaction of the organic and sulfuric acids. They discuss the syntesis of an ester and name one property of an ester.
These 37 slides start with definitions of six types of functional groups, their molecular structure, and multiple examples or each. During the rest of the presentation, organic chemistry learners are given an opportunity to practice identifying compounds based on molecular diagrams. This is an ideal way to begin the study of functional groups with your class.
College-level or AP chemists use phthalic anhydride to synthesize two different polyesters, one linear and one cross-linked in structure. A detailed materials list and well-written procedures are provided on a lab sheet. Learners write out the chemical equations for the reactions that occur. Plenty of support is provided via instructor's notes so that you can insert this into your curriculum when teaching your class about polymerization.
In this chemistry worksheet, students write the structures for the compounds listed at the top of the sheet. Then they name the compounds whose structures are illustrated. Students also write the mechanism for the reaction of methyl alcohol with propanol chloride to produce an ester.
In this naming compounds with functional groups activity, students read about using the IUPAC rules for naming these compounds and they draw structures for 3 -carbon, 2-carbon and 4-carbon molecules and give the names for each.
In this organic reactions worksheet, students are given descriptions of the seven types of reaction of organic compounds. They then answer six questions about these reactions.
For this organic chemistry review worksheet, students answer 10 questions about different organic molecules. They draw structures, they name structures, they draw polymers, they identify the type of isomer given molecules are and they identify functional groups.
High schoolers explain the process of polymerization. In this chemistry lesson, students produce carboxylesterase in the lab. They test its effectiveness in removing the by-product odor.
Your budding scholars spent the day in the library looking for a topic for their research essay, and now they are all in tears because there is too much information available on their topics. Wipe those tears away with the ideas and activities available in this resource. Developing writers collaborate, and break down large topics (WWII, terrorism, skateboarding) by brainstorming aspects, events, and associations proceeding from the topic. From their discoveries, happy learners develop a more specific and manageable topic for their writing.
A collection of 16 different chemistry crosswords provides variety in the ways that your class reviews chemistry vocabulary and concepts. Because the topics for each range from the introductory periodic table of elements to the complex energetics and kinetics, this resource is valuable to middle school and high school teachers alike. Each puzzle is comprehensive in coverage and has anywhere from 12 to 36 questions to answer. Add this to your library of review tools. US teachers, be aware that there are British spellings for some terms. In most cases, the US spelling requires the same number of letters as the British, so this shouldn't be a problem.
