Classroom Resources: Solutions
26 – 37 of 37 Classroom Resources
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.
Mixtures, Solubility, Reaction Rate, Saturated/Unsaturated/Supersaturated | High School
In this lab, students observe how particle size, solvent temperature, and agitation affect rate of solution.
Mixtures, Acid, Interdisciplinary, Acid Rain, Chemical Properties | Elementary School
In this lesson, students are presented with an environmental problem to solve using important concepts of chemistry, which involves a lake with deteriorating water quality.
Physical Properties, Mixtures, Solubility, Melting Point, Intermolecular Forces, Freezing Point, Polarity, Molecular Structure, Solute & Solvent, Intermolecular Forces, Boiling Point, Intramolecular Forces, Graphing, Mixtures, Lewis Structures | High School
In this lesson, students investigate how intermolecular forces effect physical properties by investigating substances’ melting points as well as solubility.
Observations, Density, Physical Properties, Mixtures, Mixtures | Elementary School
Students will be using three ingredients to create a liquid color-works mixture in a jar. This is a fun chemistry project to do with young elementary students around the 4th of July or New Year’s Eve to get the children excited about fireworks.
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.
Separating Mixtures, Mixtures, Interdisciplinary, Electromagnetic Spectrum, Separating Mixtures, Mixtures | Middle School
In this lab, students will learn that mixtures are created by the combination of two or more substances. Many colors are actually mixtures of several different pigments. Mixtures can be separated, and in this lab students will perform chromatography to separate mixtures found in candy and in leaves.
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.
Observations, Density, Mixtures, Chemical Change, Chemical Change, Physical Change, Acid Base Reactions, Mixtures | Elementary School
In this lab, students create a mixture of oil, water and food coloring, and then add an Alka-Seltzer tablet, to create a homemade lava lamp. Student will record their observations during each step of the process and answer follow-up questions about the chemical and physical changes that took place.
Separating Mixtures, Mixtures, Physical Change, Physical Change, Phase Changes, Introduction, Interdisciplinary, Distillation, Solute & Solvent, Mixtures | Elementary School
In this lesson, students review important concepts of the water cycle and then design, test, and evaluate a working model of a desalination plant (a distiller).
Mixtures, Concentration, Solute & Solvent, Molarity, Mole Concept, Dimensional Analysis, Measurements | High School
In this lab, students calculate concentrations of and perform dilutions of Kool-Aid and juice solutions.
Observations, Density, Mixtures, Inferences, Mixtures | High School, Middle School
In this demonstration, students will have the opportunity to observe and analyze the density of a solution. Students will interpret their observations as they compare the density of the solution with plastic components.
