    This video tells the story of Antoine Lavoisier who many consider to be the father or modern chemistry. Lavoisier discovered oxygen and hydrogen and first proposed the Law of Conservation of Mass.

  • Observations, Physical Properties, History, Model of the Atom | High School, Middle School, Elementary School

    Video: Ancient Chemistry Video

    This video traces the history of chemistry from the discovery of fire, through the various metal ages, and finally to the great philosophers.

  • Introduction, Elements, History, Periodic Table, Atoms, Subatomic Particles, Electrons | High School, Elementary School, Middle School

    Activity: Writing Your Name using Chemical Element Symbols

    In this activity, students will use their creativity to spell their name (first or middle name and their last name) using chemical symbols of elements on the periodic table. For example, you can spell Yvonne using the symbols for yttrium (Y), vanadium (V), oxygen (O), nitrogen (N), and neon (Ne).

  • Observations, Melting Point, Phase Changes, Introduction, Physical Change | Elementary School

    Lesson Plan: Let's Get Physical About Water

    In this lesson, students will learn about the phase changes of matter. During the course of two days students will perform several short experiments in order to change the state of water and they will record their observations.

  • Lab Safety | Middle School, Elementary School, High School

    Activity: What Not to do in the Chemistry Lab

    In this activity, students will examine a cartoon of a chaotic chemistry laboratory and note the specific behaviors that are dangerous and unsafe in a chemistry laboratory setting. This activity provides an opportunity for teachers to introduce laboratory safety and best laboratory practices and discuss them with their students.

  • Observations, Density, Physical Properties, Introduction, Mixture | Elementary School

    Lesson Plan: What is Density

    In this two-part lesson, students will learn about density through a teacher-led demonstration and a hands-on activity. The demonstration will give students the opportunity to observe the formation of a density tower made from common drinks. Students will then create their own density tower using simple ingredients, and then further investigate differences in density when solid objects are added to the tower.

  • Observations, Chemical Change, Reaction Rate, Reaction Rate, Catalysts, Chemical Change | Elementary School

    Lab: To What DEGREE Does it Matter

    In this lab the students will explore how factors such as temperature may influence chemical reactions. Students will use citric acid and sodium bicarbonate (Alka-Seltzer) and a catalyst (water) to induce a reaction at varying degrees. Observations will be made of the rate at which the reactions take place under these varying conditions. The students will make predictions of how the temperature of the water will affect the chemical reaction. They will use a stop watch to time the reaction between the Alka-Seltzer and the varying temperatures of water and graph their observations for analysis, they will compare data to deduce whether temperature has any influence during a chemical reaction.

  • Observations, Density, Chemical Change, Density, Combustion, Chemical Change | Middle School, Elementary School

    Demonstration: Investigating Gas Density

    In this demonstration, students will observe a reaction between baking soda and vinegar in the presence of a burning candle. The initial environment has plenty of oxygen present in order to sustain the candle’s flame; however the reaction will produce carbon dioxide which will cause the lit candle to extinguish. Students will analyze the outcome and compare the presence of the gases in the container and make determinations about the densities of each.

  • Separating Mixtures, Separating Mixtures | Elementary School

    Lab: Investigating Black Ink

    In this lab, students will discover that black ink is a mixture composed of a several different pigments through a chromatography investigation.

  • Physical Properties, Phase Changes, Introduction, Molecular Motion, Matter | Elementary School

    Lesson Plan: Introducing States of Matter

    In this lesson, students will investigate particle behavior in different forms of matter: solid, liquid and gas. Students will have an opportunity to examine a model of the particles in the different states of matter and will also participate in a kinesthetic demonstration of matter. They will also learn what makes the states of matter different from one another when changing from one form to another.

  • Observations, Phase Changes, Combustion, Chemical Change | Middle School, Elementary School

    Demonstration: The Jumping Flame

    In this demonstration, students will observe that the vapor of an extinguished candle flame is ignitable.

  • Observations, Physical Properties, Melting Point, Phase Changes, Scientific Method | Elementary School

    Lab: Ice Cube Race

    In this lab, students will investigate what factors can influence the change in state of matter from a solid to a liquid. They will have the opportunity to make a hypothesis and participate in the design and completion of an experiment.

  • Observations, Physical Properties, Matter | Elementary School

    Activity: Sorting Buttons

    In this lab, students will investigate observable properties of matter. Students will use their knowledge of physical properties to create and separate mixtures of assorted buttons based on the characteristics of color, shape and number of holes.

  • Observations, Density, Physical Properties, Introduction | Elementary School

    Activity: Sink or Float

    In this activity, students investigate whether certain materials will sink or float in water. Students will also explore how the shape of an object can affect its volume and density.
