Scientific models help explain ideas and concepts to non-experts. The online activity covers conceptual, mathematical, and physical models. Through four multiple-choice questions and three discussion questions, scholars gain a deeper...

Advanced lab apprentices prepare zinc and copper solutions to which they will compare the same minerals from a multivitamin. Using absorption spectroscopy, they analyze the contents of the multivitamin for concentration. This lab can be...

Sixth graders complete several experiments about chemical and physical changes. In this physical and chemical science instructional activity, 6th graders complete 6 experiments about chemical and physical changes. Students examine the...

Students explore the structure and property changes of water through videos and classroom discussion. They are introduced to atomic arrangement of solids by looking closely at carbon in different forms, such as graphite and diamond....

Students recognize different consumer products, found in and around the home, that have reactive or denaturing properties when used together. They explore chemical and physical properties of each product by identifying chemical formulas...

Students discuss the principles of atomic structure that underlie the operation of a photovoltaic cell and explains how they apply to a photovoltaic cell's operation. An area of the classroom is staked off to represent a photovoltaic...

There's nothing sticky about the resource, unless you count the gumdrops! Scholars create a model of a lithium atom, complete with protons, neutrons, and electrons. It's just that these models are made with gumdrops and toothpicks.

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

Liquids, gases, and solids are the states of matter in which scholars investigate in a lesson plan that offers in-depth information and engaging activities that look into the three states and the changes their properties make when mixed...

Fourth graders compare electricity and magnetism. For this science lesson, 4th graders discuss the concepts of electricity and magnetism and brainstorm examples of electrical and magnetic forces.

Students examine how nuclear reactions differ from other chemical reactions they have studied. They add up atomic masses of both the product and reactant side of an example of uranium decomposition, demonstrating mass loss involved.

Students are introduced to the periodic table. They find the common trends among the electron configurations and the names of certain groups of the table. Students explore the atomic mass, atomic number, mass number, mass and charge...

Fifth graders examine electromagnetic wave spectrum. In this science lesson, 5th graders discuss the aspects of the electromagnetic wave spectrum and complete a worksheet identifying the parts of the spectrum.

A fuel cell is where the jailer keeps gas guzzlers. Scholars review chemical reactions, chemical bonds, and chemical structure in order to apply these concepts. Participants construct fuel cell kits, using electrolysis to run the car and...

Let's get a closer look at DNA and other molecular structures. The first instructional activity in the series of four introduces a variety of imagining techniques that engineers and scientists use to visualize molecular structures. The...

Learners apply their knowledge of relativity and nuclear radiation to the concept of cold fusion. They also read the article from the website listed in the related and resource websites and discuss the article with the class.

Students participate in a small group read aloud of the short story, "Cerium" by Primo Levi. They answer several questions about the story and then relate the reading to a lecture on Kinetic theory. After the lecture they apply the...

Students read an article that introduces them to the science and applications of nanotechnology. They discuss the the everyday examples of how nanotechnology is and can be used. In small groups, they observe and make inferences about...
