  Lesson Plan: One Tube Reaction Mark as Favorite (3 Favorites)

  In this lesson, students will observe a chemical change involving oxidation and reduction.

• 

  Indicators, Acid, Chemical Properties | Middle School

  Lab: Acid & Base Mark as Favorite (0 Favorites)

  In this lab, students are given four unknown liquids and must identify whether they are acids or bases.

• 

  Culminating Project | High School, Middle School

  Activity: 24-7 Lecture Mark as Favorite (2 Favorites)

  In this activity, students must demonstrate their understanding of a topic by making a 24 second video and summarizing the concept in seven words.

• 

  Separating Mixtures, Percent Composition | Middle School

  Lab: Metallic Breakfast Mark as Favorite (0 Favorites)

  In this lab, students will separate iron filings from iron-fortified breakfast cereals. Students will use the recorded data to conduct percent composition calculations.

• 

  Percent Composition, Scientific Method, Introduction, Percent Composition | Middle School

  Lab: Mass Percent Mark as Favorite (0 Favorites)

  In this lesson, students will develop a theory of how to calculate percent composition.

• 

  Conservation of Mass, Measurements, Conservation of Mass | High School, Middle School

  Lab: Mass & Change Mark as Favorite (5 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 | High School, Middle School

  Activity: Magic Bubble Mark as Favorite (3 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, Mixture, Acids & Bases, Chemical Change | Elementary School, Middle School, High School

  Demonstration: Inflating a Balloon with Chemistry Mark as Favorite (4 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 | Middle School, High School

  Demonstration: Density Tubes Mark as Favorite (1 Favorite)

  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.

• 

  Trends of the Periodic Table, Atomic Radius, Ionic Radius, Ionization Energy, Valence Electrons | Middle School, High School

  Simulation: Periodic Trends: Ionization Energy, Atomic Radius & Ionic Radius Mark as Favorite (0 Favorites)

  In this simulation for the March 2016 issue, students can investigate the periodic trends of atomic radius, ionization energy, and ionic radius. By choosing elements from the periodic table, atoms can be selected for a side by side comparison and analysis. Students can also attempt to ionize an atom by removing its valence electrons. Quantitative data is available for each periodic trend, and can be further examined in a graph.

• 

  Culminating Project, Review | High School, Middle School

  Project: 21st Century Elements Mark as Favorite (7 Favorites)

  In this project, students will learn the importance of the elements in our lives. The students will research one chosen element and create a website, a digital comic strip, or a video to explain the important properties of the element as well as why the element is so important to our lives.

• 

  Density, Molecular Motion | Middle School, High School

  Activity: Simulation Activity: Density Simulation Mark as Favorite (4 Favorites)

  In this simulation, students will investigate the effect of changing variables on both the volume and the density of a solid, a liquid and a gas sample. Students will analyze the different states of matter at the particle level as well as quantitatively. This lesson accompanies the simulation from the September 2015 issue of Chemistry Solutions.
