The periodic table has so much more to it than meets the uninformed eye. An inquiry-based instructional activity leads learners through the history of the discovery of several transuranium elements. They then use informational resources...

This science presentation focuses on the elements in the periodic table. It begins with the parts of an atom, explaining atomic mass and atomic number, valence electrons, and isotopes. Then it moves on to discuss various ways of...

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...

Study matter in a new way with a cross-curricular assignment for language arts and math. Learners answer five reading comprehension questions after reading a few paragraphs about the periodic table, properties of elements, and how atoms...

Young scientists construct an understanding of molecular compounds in this hands-on science lesson. Using LEGO® to model the atoms of different elements, students build molecules based on the chemical formulas of common compounds.

Get down to basics with these worksheets on the structure of atoms. Challenging young chemists to identify information from the periodic table and create Bohr diagrams and Lewis dot structures for different elements, this...

Teaching young scientists about atoms is no small task, but this series of worksheets will make it a little easier. From creating and labeling Bohr models, to identifying information provided in the periodic table of elements,...

From molecules to nanotubes, an engaging unit explores the world of tiny science. Fifteen hands-on experiments and lessons engage young scientists as they learn chemistry. Discussions, worksheets, and data analysis reinforce the concepts...

Time to find out what they've learned! The final lesson of a five-part series has learners complete a 39-question multiple choice review. They use what they've learned in the previous lessons to complete questions that include concepts...

A quiz over stars and elements. Students can test their understanding of the star and element unit that covered over chemistry, periodic table of elements, and famous scientists. Quiz contains thirteen multiple choice questions.

This unit covers introductory concepts of mixtures and solutions. Students think about how mixtures and solutions, and atoms and molecules can influence new technologies developed by engineers. The first lesson explores the fundamentals...
