Classroom Resources: Solutions
1 – 15 of 15 Classroom Resources
Mixtures, Solute & Solvent | Elementary School
In this demonstration, students will recognize that there is a threshold for the amount of salt that can be dissolved into a specified amount of water. Students will be asked to make observations about two different salt water samples to determine if a sample that contains undissolved salt is still considered a solution. The saltiness, or salinity, of the water samples will be used to help students make connections about how the melting of polar ice caps is changing the average salinity of the ocean.
Mixtures, Chemical Change, Physical Change, Matter, Mixtures | Elementary School
In this activity, students will describe the steps required to complete a recipe of their choosing. They will identify any physical and chemical changes that occur throughout the process.
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.
Observations, Physical Properties, Mixtures | Elementary School
In this lab students will investigate the properties of ferromagnetic fluid and magnetism. Students will also have the opportunity to complete research about magnetic properties to help answer analysis questions.
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.
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, Reaction Rate, Chemical Change | Elementary School
In this lab, students will create a solution to observe a chemical change between food coloring in water and bleach. They will also develop the process skills of predicting, observing, and measuring temperature.
Mixtures, Freezing Point, Phase Changes | Elementary School
In this lab, students will investigate how dissolving salt (sodium chloride) in water changes the freezing point of the solution. While investigating this, they will make ice cream from small coffee creamer cups.
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, 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, 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.
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.
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).
