Nothing says organization quite like a table. The third lesson in a six-part Mixtures and Solutions unit teaches young scientists about elements and the periodic table. They learn how the periodic table is organized and about the...

Teach your class to think of electrons as tiny packets of energy that travel in waves. Through a short video and diagram, participants see how electrons are located around the nucleus of an atom. They then get into groups and try to...

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.

Bacteria outnumber all other forms of life on Earth. Scholars observe the growth of bacteria in petri dishes to understand their role in maintaining good health. Then, they observe the growth of bacteria after they introduce...

Elements, to the rescue! Scholars first review the periodic table, and then learn about the first 20 elements and their properties and uses in the fourth of six lessons in the Mixtures and Solutions unit. Applying their newfound...

How do scientists identify which elements originate from meteorites? Scholars learn about a sample of material found in a remote location, analyzing the sample to determine if it might be from Earth or not. They study elements, isotopes,...

Climate models mathematically represent the interactions of the atmosphere, oceans, land, sun, surface, and ice. Part two in the series of four lessons looks at the role greenhouse gases play in keeping Earth warm and has participants...

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...

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...

Students explore naturally magnetic elements. In this magnets lesson, students examine the periodic table of elements. Students discover the parts of an atom and determine which three elements are magnetic.

Fifth graders investigate the nature of matter and of the scientific processes associated with them in this series of lessons.

By measuring the wavelength, frequency, and intensity of electromagnetic radiation, scientists determine the temperature, density, and composition of far away items. Scholars rotate through ten lab stations using a spectroscope at each...

Is the sun the only celestial body with magnetic fields? A guided discussion on the weather in space is designed with a mix of questions, discussions, explanations, and applications. Additionally, the resouce includes an...

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...

Learners discuss the difference between atoms and elements. They analyze how compounds are formed. Students discuss the difference between covalent bonds, hydrogen bonds, and ionic bonds. They review bonding with diagrams, "Atoms or...

Fifth graders investigate atoms. In this atom lesson, 5th graders investigate the parts of an atom. Students explore atom numbers and determine the number of electrons is in each atom.

Cyanide, a coordination compound, is used in the extraction of gold and silver. Part 24 in the series of 36 delves into the world of coordination compounds. Classes learn, through readings, discussions, and answering questions, how to...

Eighth graders define the pH scale, acids and bases. They distinguish between acidic and basic solutions using litmus paper. Students review simple chemical formulas. They define the subscript and coefficient in terms of chemical...

Young scholars verbalize a simple particle theory, They apply their particle theory to explain what happens during chemical reactions and how this theory supports the law of conservation of matter. Pupils comprehend that the atomic...

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...

In a comprehensive role playing activity, teens play the parts of different stakeholders in the realm of acidic oceans. They research, debate, and create a presentation from the perspective of either ocean organisms, the fishing...

Students articulate a possible relationship between arsenic and gold deposits in a written statement using data to substantiate the relationship they describe. They use real data to determine the source of the arsenic in the drinking...

How do one's habits and lifestyle choices affect the environment? Through a short online survey, learners will calculate their own carbon footprints then determine how to reduce their impact on the environment through simple steps, such...

What killed the dinosaurs and how do scientists know? Your high schoolers can examine these fascinating questions with a geochemical lens using the engaging 33-minute video, the accompanying data interpretation, and some thoughtful...
