Classroom Resources: Solutions
1 – 15 of 15 Classroom Resources
Mixtures, Melting Point, Freezing Point, Phase Changes, Freezing Point Depression | Middle School, High School
In this lab, students will consider why salt is used to aide in snow clearing and to help keep icy roads safe. They will investigate how salt ‘melts’ ice and determine the best type of salt to do so. Additionally, students will explore the advantages and disadvantages of the various different types of salt.
Density, Mixtures, Solubility | Middle School
In this lab students will make a simple yet spectacular lava lamp while focusing on the density of the components.
Observations, Physical Properties, Mixtures, Solute & Solvent, Mixture | Middle School
In this lesson students explore the viscosity of different mixtures. They measure viscosity of different mixtures and then have the opportunity to design a mixture to attain a particular viscosity. Students will relate their lab experience to the application of viscosity in the real-world as they consider the differences in viscosity between different types of paints.
Separating Mixtures, Physical Properties, Mixtures, Solute & Solvent | Middle School, Elementary School
In this lab students will compare and contrast mixtures and solutions. They will be tasked with extracting iron from various breakfast cereals. They will then conclude which cereal would be the healthiest for Iron Man to eat for breakfast.
Mixtures, Intermolecular Forces, Molecular Formula, Polymers, Molecular Structure, Solute & Solvent, Intermolecular Forces, Electromagnetic Spectrum | High School, Middle School
This video investigates the composition of paint, while analyzing the fundamental chemistry principles of its main components. Students will learn about the differences between three common paint types, water colors, oil-based and acrylic paint as well as the chemistry of each.
Mixtures, Molecular Structure, Electromagnetic Spectrum | High School, Middle School
This video discusses the chemistry of pigment molecules and how they are used to give paints their specific color. Students will learn about the importance of a pigment’s molecular structure, how they are physically suspended to create a paint color, as well as how they interact with light.
Observations, Physical Properties, Mixtures, Chemical Properties, Separating Mixtures | Middle School, Elementary School
In this lesson, students will compare polluted and filtered water to observe how filtering can remove some kinds of pollutants. Students will also be asked to consider how people affect ecosystems and use the scientific method to conduct an experiment on polluted water.
Mixtures, Interdisciplinary, Concentration, Measurements, Scientific Method | High School, Middle School
In this lab, students will observe how salt concentration can affect the structure of a potato tuber.
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**
Observations, Physical Properties, Mixtures, Interdisciplinary, History, Chemical Properties | High School, Middle School
In this lab, students will learn about the history of invisible ink and will have the opportunity to compare two types of homemade invisible ink recipes.
Mixtures, Solubility, Percent Composition, Concentration, Solute & Solvent | Middle School
In this lab, the students will investigate how the concentration of a solution affects its properties such as color and taste.
Separating Mixtures, Mixtures, Solubility, Phase Changes, Physical Change | Middle School
In this lab, students will perform a step by step process of mixing and separating substances based on their states and solubility in order to solve a problem.
Observations, Physical Properties, Mixtures, Intermolecular Forces, Polarity, Intermolecular Forces, Mixture | 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.
Separating Mixtures, Density, Mixtures, Chemical Change, Intermolecular Forces, Physical Change, Intermolecular Forces | Middle School
In this lab, students will consider and utilize various separation techniques to purify and reclaim used motor oil.
Physical Properties, Mixtures, Molecular Structure, Mixture | 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.
