Classroom Resources: Chemistry Basics
26 – 29 of 29 Classroom Resources
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.
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.
Physical Properties, Polymers, Mixture, Scientific Method | 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.
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.
