Classroom Resources: Molecules & Bonding
1 – 12 of 12 Classroom Resources
Observations, Physical Properties, Physical Change, Polymers | Middle School, Elementary School
In this lab students will research and compare the physical properties of various types of plastic bags. The recorded data will be analyzed by students, and they will use the results to design a plastic bag to meet a given set of criteria.
Observations, Physical Properties, Mixtures, Polarity | Elementary School
In this demonstration, students will observe as the teacher creates several colorful mixtures. Using food coloring, water and milk, students will watch the colors swirl and mix. Students will have the opportunity to make a prediction about what will happen to the colors when a sample of soap is introduced to the mixture.
Phase Changes, Conservation of Matter, Polymers, Chemical Change | Elementary School
In this lesson, students explore the science behind chemical reactions as well as the processes used by chemical engineering principles to develop new materials. The idea that mixing two substances can result in an explosion, the release of gas, and the formation of an entirely new substance is both fascinating and mysterious to most young students.
Mixtures, Solubility, Intermolecular Forces, Polarity, Solute & Solvent, Intermolecular Forces, Molecular Geometry | High School, Middle School, Elementary School
In an animation, students will have an opportunity to visualize on the particulate level how solubility works. Examples of ionic compounds and a polar covalent compound show how when water is attracted to charged parts, they dissolve, and when they're not attracted to charged parts they stay solid. **This video has no audio**
History, Periodic Table, Molecular Structure, Molecular Structure , Molecular Geometry | High School, Middle School, Elementary School
In this video, Sam Kean tells the story of how phosphorus was at the center of the race to discover the structure of DNA.
Polarity, Molecular Formula, Covalent Bonding, Ionic Bonding | High School, Middle School, Elementary School
"In this animation, students will visualize how different chemical bonds form. Examples of ionic, covalent, and polar covalent bonds are animated, and then students are given a sample of compounds to predict the bonding types. **This video has no audio**"
Observations, Physical Properties, Mixtures, Intermolecular Forces, Polarity, Intermolecular Forces, Mixtures | High School, Elementary School, Middle School
In this lab, students mix polar and nonpolar substances and then add various emulsifiers to encourage the mixing of the two substances. They use ingredients in salad dressing to relate science to real life scenarios.
Physical Properties, Polymers, Scientific Method, Mixtures | Middle School, Elementary School
In this lab, students will follow the procedure for creating a polymer, flubber, which will be similar in consistency to Silly Putty. Students will then design an experiment to test a physical property of the flubber that they have created using the scientific method.
Elements, Interdisciplinary, Molecular Formula, Conservation of Mass, Conservation of Matter, Molecular Structure, Balancing Equations, Reversible Reactions, Chemical Change, Matter, Photosynthesis, Monomer | Elementary School
In this lesson, students will explore a simple, but key, biochemical reaction: photosynthesis.
Observations, Physical Properties, Introduction, Polymers | Elementary School
In this activity, students explore the chemical reaction between borax and glue, creating a polymer ball. The properties of the polymer ball will be analyzed and compared to a store bought bouncy ball.
Physical Properties, Mixtures, Molecular Structure, Mixtures | High School, Middle School, Elementary School
In this demonstration, the teacher will create a sequence of mixtures in a single test tube. Water, oil, food coloring and soap will be used in this demonstration to introduce the concepts of heterogeneous and homogeneous solutions as well as the idea of miscibility. Students will also have the opportunity to analyze the properties, such as surface tension of each component used.
Naming Compounds, Elements, Interdisciplinary, Atoms, Molecular Structure, Matter, Chemical Bond | Elementary School
In this lesson, students explore the structure of matter by designing, building, comparing, and evaluating models of a variety of simple molecules.
