Does the change in energy of matter lead to a change in mass? Upcoming chemists compare the mass of equal-volume, but different-temperature liquids and materials both before and after a chemical reaction has occurred. In another...

Discover how the periodic table tells the story of its elements. Learners begin by studying the makeup of several mixtures. Their analysis leads to a discussion of elements and the periodic table. As they dig deeper, they understand the...

Because of the work of John Dalton, we are able to write formulas for compounds. The hands-on experiment has scholars prepare a compound from its elements. Using mass data, individuals write the empirical formula for the compound.

What makes up the air we breathe? Young scientists explore the atoms and molecules in the air. An interactive lesson allows individuals to watch the movement of the particles in the air and change the makeup from a mixture to a...

Students examine the differences between elements, compounds and mixtures. Using diagrams, they compare and contrast atoms and molecules and describe various chemical reactions. They distinguish the differences between ionic and...

Fifth graders explore the differences between elements.  In this elements and atoms lesson students complete an activity that shows how chemicals react to a flame test. 

Students define vocabulary related to the parts of the atom.  In this matter lesson, students navigate the web to find the structure and the forces that affect atoms.  Students complete an experiment with positive and...

Learners investigate common household items and classify them into types of matter. In this matter instructional activity, students group given items into categories based on their characteristics. They also complete a concept map about...

High schoolers are introduced to the elements on the Periodic Table and what is meant by element. Using the Table, they identify the name, atomic mass, number and symbol of each element. To end the lesson, they discover the...

Students engage in a lesson about the scientific concept of matter. They use essential questions in order to guide the research process. Students engage in several class inquiries that are hands on in order to investigate the properties...

"Up and Atom" is a mini-unit introducing middle-schoolers to the wonders of elements. Participants draw atom models, examine the periodic table, compare samples of metals to nonmetals, identify unknown elements, and more! The beginning...

Students investigate elements by by defining scientific terms.  In this Periodic Table of Elements lesson plan, students utilize a glass of water, and powdered fruit drink to perform a lab activity demonstrating properties of...

Learners perform a review assignment in 3 portions to review chemistry compounds, formulas, and equations. The assignment consists of several different portions that can be used as assessments. The majority of the lesson plan is composed...

Eighth graders read and interpret the Periodic Table. They also make decisions on how to group and arrange different kinds of matter and draw the structure of atoms of pure elements. Finally, 8th graders contrast and compare basic...

Students complete a unit of activities to learn about states of matter and how to measure matter. In this matter lesson, students complete 8 lessons to learn about matter, its states, and how to measure matter.

Eighth graders analyze physical change in mass. In this chemistry instructional activity, 8th graders describe, measure and calculate the amount of physical change occurring in mass before and after the change. Students should be...

Students investigate the Periodic Table of Elements. The teacher is provided with the necessary background information to complete the lesson. Students practice matching the element symbol to its place on the chart.

Jump back into expository writing and analysis at the start of a new school year! Start with a review of an authors' stylistic choices in diction, syntax, treatment of subject matter, and figurative language. Writers choose a text to...

Students use indicator paper to determine if substances are acidic, basic, or neutral. They test for Ph levels in them. They investigate the effect of oxygen on darkening fruit cut and exposed to the air. They observe vitamin C as an...
