  • 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.

  • 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.

  • Observations, Reaction Rate, Reaction Rate, Chemical Change | High School, Elementary School, Middle School

    Demonstration: Simple Kinetics

    In this demonstration, students will see that different food dyes react with bleach at different rates.

  • Observations, Physical Properties, Mixtures, Intermolecular Forces, Polarity, Intermolecular Forces, Mixture | High School, Elementary School, Middle School

    Lab: Salad Dressing Science: Emulsions

    In this lab, students mix polar and nonpolar substances and then add various emulsifiers to encourage the mixing of the two substances. They use ingredients in salad dressing to relate science to real life scenarios.

  • Observations, Chemical Change, Inferences, Interdisciplinary, pH, Chemical Change | Elementary School

    Lesson Plan: Strawberry DNA & CSI

    In this lesson, students will extract DNA from strawberries and analyze evidence to figure out who perpetrated a petty crime.

  • Observations, Density, Interdisciplinary, Scientific Method | Elementary School, Middle School

    Lab: Crush's Dilemma

    In this lab, students explore the concept of density. They will examine the density of a plastic sandwich bag compared to water. Students will create their own experiment and investigate factors that affect floating and sinking.

  • Observations, Phase Changes, Physical Change, Temperature | Middle School, Elementary School

    Lab: Condensation

    In this lab, students will explore the process of condensation. Students will investigate how water vapor condenses, and then they will conduct a comparison test to see if cooling water vapor has an effect on the rate of condensation.

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

    Activity: Color-Works in a Jar

    Students will be using three ingredients to create a liquid color-works mixture in a jar. This is a fun chemistry project to do with young elementary students around the 4th of July or New Year’s Eve to get the children excited about fireworks.

  • Observations | High School, Elementary School, Middle School

    Activity: Compare and Contrast

    In this activity, students will use their observation skills to compare and contrast two similar chemistry classroom scenes in order to identify the differences between the two.

  • Observations, Chemical Change, Acid, Interdisciplinary, Chemical Change, Acid Rain | Elementary School

    Lab: Chemical Weathering of Rocks

    In this lab, students will explore simulated reactions that contribute to chemical weathering of certain rocks as it appears in nature.  They will compare the effects of two different chemicals as it contacts various rock and mineral samples.

  • Observations, pH, Acid Base Reactions, Indicators, Chemical Properties | Elementary School

    Lab: Can a Cabbage Distinguish an Acid from a Base?

    In this lab, students will first determine what colors the cabbage indicator turns in acidic, neutral, and basic solutions.

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

    Activity: Bouncy Ball

    In this activity, students explore the chemical reaction between borax and glue, creating a polymer ball. The properties of the polymer ball will be analyzed and compared to a store bought bouncy ball.
