In this activity, students investigate different methods (aeration and filtering) for removing pollutants from water. They will design and build their own water filters.

This activity is a guided inquiry where students will investigate if water molecules have any space between them.

These are activities where students explore chemical reactions, as well as the effects of concentrated solutions.

Students learn about the periodic table and how pervasive the elements are in our daily lives. After reviewing the table organization and facts about the first 20 elements, they play an element identification game. They also learn that engineers incorporate these elements into the design of new products and processes. Acting as computer and animation engineers, students creatively express their new knowledge by creating a superhero character based on of the elements they now know so well. They will then pair with another superhero and create a dynamic duo out of the two elements, which will represent a molecule.

This is a teacher demonstration used to show an example of kinetic molecular energy using food coloring and water. The students are also given opportunity to develop their own questions and tests.

A lesson on states of matter using marbles for molecules expands into 3 more lessons elaborating on properties of a gas.

This is a teacher demonstration used to show an example of kinetic molecular energy using food coloring and water. The students are also given opportunity to develop their own questions and tests.

This activity provides for small group investigation of the properties of different liquids leading to the discovery that liquids are different in many ways, including density.Students would be led to a very beginning understanding of density.

This activity is an extension where students freeze a liquid, making ice cream.

This activity is a classroom lab where students will conduct a controlled activity resulting in the growth of salt crystals, showing a dramatic physical change.

Students use gumdrops and toothpicks to make lithium atom models. Using these models, they investigate the makeup of atoms, including their relative size. Students are then asked to form molecules out of atoms, much in the same way they constructed atoms out of the particles that atoms are made of. Students also practice adding and subtracting electrons from an atom and determining the overall charges on atoms.

This activity helps students understand how mixtures are formed. They will make predictions regarding the rate of mixing. Students should report that the variation of heated water and crushed sugar creates the shortest mixing time.

The students will investigate how one liquid will change the color of another.

An elementary introduction to chemistry vocabulary, tools and concepts used in science curriculum.

This activity is a classroom investigation where students separate pigment in dyes in order to learn about mixtures and solutions. They use chromatography to design and experiment with a single variable to answer a question about which ink will separate the most - has the greatest variety of pigment.

This activity is a lab investigation where students design an experiment to extract pigments (AKA chromatography) from different colored, water soluble markers.

This activity is a lab investigation where students design an experiment to extract pigments (AKA chromatography) from different colored, water soluble markers.

In this chemistry lab experiment, students explore the properties of color using chromatography. Students will observe and compare color patterns to differentiate compositions of various colors. Students gather data on color patterns and develop new experimental questions based on their data.

This activity is an interactive demonstration of the concept of density with a guided inquiry component.

This activity is a guided inquiry of how molecules move in liquid. Students develop questions, use their observation skills to describe what they saw, record and analyze their findings, and use their data to begin to hypothesize what is happening in the investigation.
