Students mix two different solutions to become more familiar with molecules and polymers. In this chemistry instructional activity, students decide whether or not the reaction between two solutions is chemical or physical. Students then observe the newly made material and examine its properties.
Students investigate what happens when mixing two solutions. In this solutions lesson, students experiment to explain what happens when mixing two solutions and to tell what polymers are. They follow directions carefully to complete an experiment in which they make a silly putty type material.
In this molecular compounds worksheet, students fill in 9 blanks with the appropriate terms related to bonding and molecules, they determine if 5 statements are true or false, they match 5 terms with their meanings and they solve 3 problems about atoms, molecules and compounds.
The molecular properties of water are the focus of this chemistry-based assignment. Multiple-choice, true-or-false, matching, and fill-in-the-chart style questions query assignees about the forces that hold the water molecule together, reactions between water and other materials, which ions are important to life, and more. Because the focus of the worksheet is water, this may be best used as a quiz in a biochemistry class.
Students investigate properties of common molecules. In this chemistry instructional activity, students construct polymer models to gain a better understanding of the properties of polymers.
A very neat worksheet has been produced by Pearson Education, Inc. for use in a general chemistry class. The first nine questions are fill in the blanks for a paragraph about types of bonds and electronegativity. Five true-false questions and five matching descriptions follow. This would make an ideal pop quiz!
Students explore natural resources by reading a science story in class. In this fibers lesson, students identify and discuss the differences between fibers such as wool, silk, rayon, linen and cotton. Students identify the common uses of these fabrics and read a story called Poly Mer in class.
Students explore how technology and science have created the plastics that make toys. For this industrial processes lesson students work on their own injected molded product and a blow molded product.
Two scenarios are presented for chemistry detectives to decipher. Both require the use of an infrared spectrometer and focus on the examination of polymer materials. In the first, lumps in polyethylene bottles are analyzed. In the second, two specific brands of plastic food wrap are compared. Lab groups can choose from one of these two open-ended science inquiries. They are both terrific lessons for studying properties of polymers, spectroscopy, or simply practicing the scientific process.
Students explore the different types of polymers while participating in a hands-on activity. The students, themselves, will be the different atoms and molecules involved in making a polymer to help them learn about the structure of these unique molecules.
Young scholars analyze and identify polymers and polymerization reactions. They explore how they are formed as well as list their characteristics, main types and recognize their properties. Statements are given to explain when dehydration occurs between two monomer molecules.
What a terrific demonstration! Watch Steve Spangler stick a wooden skewer through a balloon. He demonstrates the effect of stretching polymers with this amazing activity. Use it during your chemistry class when studying molecules.
Have investigators tear apart a fresh disposable diaper to examine the highly absorbent sodium polyacrylate ingredient. This is an absorbing activity for young chemists when studying the properties of polymers. They experience firsthand how polymers are put to practical use!
Using a step-by-step explanation of the process, this film shows how to use a wooden skewer to pierce a balloon without popping it. Your learners will love this demonstration and they will learn that polymer molecules can stretch and wrap around other objects.
Little learners will have fun playing with plastic if you do this activity with them. Have them write a message on Teflon tape, disguise it, and then pass it to a friend to decode. What they will find is that some polymers have an amazing ability to stretch in one direction, and then be pulled back into shape.
Venture into the world of macromolecules with three exciting, distinct laboratory activities. Young chemists examine the forms of carbon and discover how they are associated with atomic arrangement, construct models of carbon-containing molecules, and compare six types of plastic by density. The teachers' pages are comprehensive; They contain background information, procedures, professional-quality diagrams, and suggestions for assessments.
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.
Students perform tests for the presence of certain macromolecules. In this health and biology lesson, students rotate in groups to three lab stations and perform tests for proteins, lipids, and carbohydrates found in familiar foods.
Students investigate the physical properties of a rather peculiar substance commonly known as slime. They devise and carryout a procedure for testing the effect of varying concentrations of either the poly(vinyl alcohol) or the borax solution on slime. Teacher guide available at website.
This is a polished presentation of the nucleic acids. It is unique in that it examines both the genetic material and the energy molecules. Usually these are addressed separately even though they are both nucleic acids. This approach is most appropriate for your biochemistry buffs. It is straightforward, educational, and contains explanatory diagrams. It earns an A+!
