Students will: determine the number of protons, neutrons, and electrons for a given element by using the periodic table; construct and draw models and diagrams of atoms; use the concept of the stable octet to predict simple molecular formulas; and distinguish between elements and compounds.

In this lesson, students learn about homogenous and heterogeneous mixtures. They will then devise a way to separate a heterogeneous mixture of salt, black pepper, and sand using the equipment available to them. This lesson begins on p. 24 of the pdf document.

This is a culminating activity to be used after completion of a Thermochemistry unit, or later in the curriculum as review or evidence of concept retention.  Students will create and label a heating curve, and explain what is happening on a molecular level using Livescribe Echo pens.

In this interactive students will learn chemistry concepts by discovering how "Croda" products transform the bathroom from a disarray to a fully functional clean bathroom. There are articles attached for students to review about various topics.

This inquiry-based activity reinforces the idea that a mixture can be taken apart by physical means. Students will have 3 hours to separate as much pure substance as they can. These will be broken into percentages based on purity and the amount they have been able to separate. There is no set procedure for this open, inquiry-based activity; students will record the procedure they use as they complete the activity.

This resource supports English language development for English Language Learners. Students will study various aspects of atomic theory and elements and incorporate language objectives in this SIOP unit. The resource includes targeted vocabulary, student worksheets, and activities across all language domains.

This chapter from the online textbook Everything Science discusses classification of matter and outlines the differences between elements, compounds, and mixtures. Each chapter comes with video lessons and explanations which help bring the ideas and concepts to life.

In this activity, students will work in small groups to take vocabulary words and concepts about solutions and phase changes and break them down to the level of lower elementary age children. This will be done by writing and illustrating a children's book. Students will learn by teaching the subject and working with peers. Students are expected to come away with a solid understanding of solutions and phase changes that they were largely responsible in building themselves.
