  Conservation of Mass, Matter, Conservation of Matter, Conservation of Matter, Conservation of Mass, Balancing Equations, Chemical Change, Predicting Products, Experimental Design, Chemical Change, Observations | High School

  Lab: Matter Matters Mark as Favorite (18 Favorites)

  In this lesson, students will investigate the Law of Conservation of Mass.

• 

  Conservation of Mass, Measurements, Conservation of Mass, Chemical Change, Observations, Physical Change, Chemical Change | High School, Middle School

  Lab: Mass & Change Mark as Favorite (16 Favorites)

  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.

• 

  Physical Change, Mixtures, Observations | High School, Middle School

  Activity: Magic Bubble Mark as Favorite (6 Favorites)

  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.

• 

  Chemical Change, Observations, Acids & Bases, Chemical Change, Mixtures | Elementary School, Middle School, High School

  Demonstration: Inflating a Balloon with Chemistry Mark as Favorite (29 Favorites)

  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.

• 

  Density, Observations, Inferences, Mixtures, Mixtures | Middle School, High School

  Demonstration: Density Tubes Mark as Favorite (3 Favorites)

  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.
