It's electronic! Pupils uncover elements and their electron configurations as they explore mass, groupings, correct charges, and sliding theory. Young scientists learn creative ways to remember various elements and correctly...

Students explore how to show evidence of subshells and electron filling on the visual scale. They examine subshell filling and evaluate unknowns based on the atomic emission spectrum. Students design an experiment to identify colors of...

Students discover that there are many facets to the electron in chemistry such as electron cloud. They view movies an animations of electrons. Students visit links pertaining to electrons.

Students illustrate paramagnetic and diamagnetic differences due to the unfilled and filled valence shells. They prepare saturated solutions and place into test tubes.

Create a model to study a microscopic phenomenon. The seventh of 12 lessons uses an egg (without its shell) to represent a cell membrane. Using different solutions, learners explore the concept of cell diffusion. They monitor...

Students explore ionic bonding. They draw examples of ionic bonding and explain the activities of the electrons of the elements. Students use paper plates and candy to draw electron configurations of given atoms.

Fourth graders study the charges on ions and familiarize themselves with a quick way to remember charges based on location of elements on the periodic table. They complete a worksheet and share their answers with the class.

Students work together to explain the VSEPR theory and how it relates to molecules. They name electron pairs that can surround the central atom of an organism. They discuss the factors that determine the polarity of a molecule as well.

Students observe, describe, and record characteristics of ocean animals (mammals and fish) and sea shells. They conduct an experiment comparing and contrasting sugar water, salt water and fresh water and create a mural of coral reef...

Fourth graders participate in a simple experiment that shows the ratio of elements that make up water.

Students study the importance of alkaline earth metals.  In this metals lesson students research the minerals that are essential for human health. 

Students cuminate their study of molecular structure and bonding with this activity.

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...

Pupils discover a pattern to mysterious eggs made by their teacher. For this mass lesson, students must uncover a secret pattern given plastic eggs and a balance. Pupils find the eggs have been created with a pattern and draw them...

Fourth graders paricipate in a demonstration about bond strengths and bond types.

Students describe how elements are arranged on the periodic table. They compare metals, nonmetals, and metalloids based on their properties and on their locations in the periodic table. Students describe the differences between a...

Students use X-ray data to identify an object as a rotating neutron star, and determine its period of rotation. They use XTE observations of the Crab Pulsar to determine the period of the light intensity, interpret this period as the...

Fourth graders identify eleven white substances that are commonly found in the household. They, in pairs, perform experiments on a variety of substances, and must identify them based on the reactions they observe.

Fourth graders improve their understanding of Graham's Law by using properties of gases to evaluate the rate of effusion of two compounds as they vaporize. They engage in a lab which elevates their understanding of the properties of gases.
