• Mixtures | Middle School, High School

Access is an AACT member benefit. Lesson Plan: Making Sense of Milk

In this lesson, students will compare and contrast the chemical compositions of different types of plant milk and animal milk by analyzing data and developing models.

• Freezing Point Depression, Mixtures, Phase Changes, Freezing Point, Melting Point | High School, Middle School

Access is an AACT member benefit. Lab: How does Salt "Melt" Ice?

In this lab, students will consider why salt is used to aide in snow clearing and to help keep icy roads safe. They will investigate how salt ‘melts’ ice and determine the best type of salt to do so. Additionally, students will explore the advantages and disadvantages of the various different types of salt.

• Density, Mixtures, Solubility | Middle School

Access is an AACT member benefit. Lab: Investigating Density within Lava Lamps

In this lab students will make a simple yet spectacular lava lamp while focusing on the density of the components.

• Mixture, Physical Properties, Observations, Mixtures, Solute & Solvent | Middle School

Access is an AACT member benefit. Lesson Plan: How Fast Does it Flow?

In this lesson students explore the viscosity of different mixtures. They measure viscosity of different mixtures and then have the opportunity to design a mixture to attain a particular viscosity. Students will relate their lab experience to the application of viscosity in the real-world as they consider the differences in viscosity between different types of paints.

• Separating Mixtures, Physical Properties, Mixtures, Solute & Solvent | Elementary School, Middle School

Access is an AACT member benefit. Lab: What Does Ironman Eat for Breakfast?

In this lab students will compare and contrast mixtures and solutions. They will be tasked with extracting iron from various breakfast cereals. They will then conclude which cereal would be the healthiest for Iron Man to eat for breakfast.

• Mixtures, Solute & Solvent, Intermolecular Forces, Intermolecular Forces, Molecular Formula, Molecular Structure, Polymers, Electromagnetic Spectrum | Middle School, High School

Access is an AACT member benefit. Video: What is Paint? Video

This video investigates the composition of paint, while analyzing the fundamental chemistry principles of its main components. Students will learn about the differences between three common paint types, water colors, oil-based and acrylic paint as well as the chemistry of each.

• Electromagnetic Spectrum, Molecular Structure, Mixtures | Middle School, High School

Access is an AACT member benefit. Video: What are Pigments? Video

This video discusses the chemistry of pigment molecules and how they are used to give paints their specific color. Students will learn about the importance of a pigment’s molecular structure, how they are physically suspended to create a paint color, as well as how they interact with light.

• Separating Mixtures, Observations, Physical Properties, Chemical Properties, Mixtures | Elementary School, Middle School

Access is an AACT member benefit. Lesson Plan: Clean-Up Pond Pollution

In this lesson, students will compare polluted and filtered water to observe how filtering can remove some kinds of pollutants. Students will also be asked to consider how people affect ecosystems and use the scientific method to conduct an experiment on polluted water.

• Concentration, Mixtures, Interdisciplinary, Scientific Method, Measurements | Middle School, High School

Access is an AACT member benefit. Lab: Effect of Salt Concentration on Plants

In this lab, students will observe how salt concentration can affect the structure of a potato tuber.

• Solubility, Solute & Solvent, Mixtures, Intermolecular Forces, Intermolecular Forces, Polarity, Molecular Geometry | Elementary School, Middle School, High School

Access is an AACT member benefit. Animation: Solubility Animation

In an animation, students will have an opportunity to visualize on the particulate level how solubility works. Examples of ionic compounds and a polar covalent compound show how when water is attracted to charged parts, they dissolve, and when they're not attracted to charged parts they stay solid. **This video has no audio**

• History, Interdisciplinary, Physical Properties, Chemical Properties, Observations, Mixtures | Middle School, High School

Access is an AACT member benefit. Lab: Top Secret

In this lab, students will learn about the history of invisible ink and will have the opportunity to compare two types of homemade invisible ink recipes.

• Concentration, Solute & Solvent, Mixtures, Solubility, Percent Composition | Middle School

Access is an AACT member benefit. Lab: The Perfect Kool-Aid Concentration

In this lab, the students will investigate how the concentration of a solution affects its properties such as color and taste.

• Mixtures, Separating Mixtures, Solubility, Physical Change, Phase Changes | Middle School

Access is an AACT member benefit. Lab: A Solution to Your Mix-up

In this lab, students will perform a step by step process of mixing and separating substances based on their states and solubility in order to solve a problem.

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

• Separating Mixtures, Density, Physical Change, Chemical Change, Mixtures, Intermolecular Forces, Intermolecular Forces | Middle School

Access is an AACT member benefit. Lab: Clean it Up!

In this lab, students will consider and utilize various separation techniques to purify and reclaim used motor oil.
