    Lesson Plan: Investigating Water's States of Matter

    In this lesson, the students will identify properties of different states of matter, and then work in groups to model molecular arrangement in the solid, liquid, and gaseous states of water. This lesson will also help students to understand that the change in state as a physical change and how the solid state of water has unique properties.

  • Observations, Physical Properties, Mixtures | Elementary School

    Lab: Ferromagnetic Fluid

    In this lab students will investigate the properties of ferromagnetic fluid and magnetism. Students will also have the opportunity to complete research about magnetic properties to help answer analysis questions.

  • Physical Properties | Elementary School

    Activity: The Attraction of Magnets

    In this activity, students will be able to investigate the physical property of magnetism and determine that magnets have the ability to attract and repel some objects while pushing and pulling “race cars” around a track.

  • Observations, Physical Properties, Mixtures, Polarity | Elementary School

    Demonstration: Colorful Milk

    In this demonstration, students will observe as the teacher creates several colorful mixtures. Using food coloring, water and milk, students will watch the colors swirl and mix. Students will have the opportunity to make a prediction about what will happen to the colors when a sample of soap is introduced to the mixture.

  • Density, Phase Changes | Elementary School

    Lab: Making Clouds

    In this lab students will investigate liquid density by creating model “clouds” with shaving cream in a glass of water. They will add food coloring in order to make the clouds heavy and cause them to rain.

  • Interdisciplinary, Indicators | High School, Middle School

    Lab: Exhaling Acid

    In this lab students will observe how increased carbon dioxide levels lead to a build-up of acidic conditions.

  • Elements, Periodic Table | High School, Middle School

    Activity: Periodic Table of Mistakes

    In this activity, students will examine a periodic table that contains 25 mistakes. Students will be tasked with comparing the Periodic Table of Mistakes to a real periodic table in order to determine what mistakes are present. This activity provides an opportunity for students to become more familiar with the periodic table, including element names, symbols and placement, as well as trends in atomic mass.

  • Phase Changes, Physical Change | Middle School

    Lab: I Can’t Believe It’s Butter!

    In this lab students will learn about the phases of matter and phase changes while making a small sample of butter.
