    Lab: Apple's Oxidation

    In this lab students will learn about the chemical reaction, oxidation, using apple wedges. They will apply different substances to a number of apple wedges to determine if these applications have any impact on the oxidation process. Students will also use a control sample so that they compare their results with an apple wedge that has not had any substance added to it. Students will measure and record the time it takes to see the changes to the apple which indicate oxidation. 3-46

    Lesson Plan: The Chemistry of Eggs

    In this lesson students will learn that vinegar can react with the Calcium in an egg shell to make it rubbery. First, the students will listen to the teacher read a book about eggs. The teacher will then put an egg in a jar with vinegar and let it set for two days. Students will make a prediction about what they think will happen to the egg, and then together they will investigate the final results.

    Activity: Discovery Tubes

    This is a fun, visual activity for young students. It allows for understanding of fundamental chemistry topics, including mixtures, miscibility, density and viscosity while analyzing a handheld colorful toy.

  • Observations, History, Conservation of Mass, Measurements, SI Units | Elementary School, Middle School, High School

    Video: Antoine Lavoisier Video

    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 | Elementary School, Middle School, High 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.

  • 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.

  • Observations, Density, Physical Properties, Introduction, Mixtures | 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 | Elementary School, Middle 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.

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