Classroom Resources: Chemistry Basics
126 – 130 of 130 Classroom Resources
Observations, Chemical Change, Conservation of Mass, Conservation of Matter, Balancing Equations, Conservation of Mass, Chemical Change, Matter, Conservation of Matter, Predicting Products, Experimental Design | High School
In this lesson, students will investigate the Law of Conservation of Mass.
Observations, Chemical Change, Physical Change, Conservation of Mass, Conservation of Mass, Chemical Change, Measurements | Middle School, High School
In this lab, students will use unified particle pictures of solid, liquid, and gas to explain the law of conservation of mass after carrying out various experiments.
Observations, Physical Change, Mixtures | Middle School, High School
In this lesson, students will create and interpret particle diagrams that represent elements and compounds at the molecular level. They will also describe the process of dissolving and create particle diagrams that represent mixtures at the molecular level.
Observations, Chemical Change, Acids & Bases, Chemical Change, Mixtures | High School, Middle School, Elementary School
In this demonstration, the teacher will perform a reaction between acetic acid (vinegar) and sodium bicarbonate (baking soda) in order to inflate a balloon and to introduce the concept of a chemical reaction to students. Students will observe the reaction, and identify indicators of chemical change as well as discuss the different types of matter that are involved.
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.
