Many periodic tables mention specific heat, but how do scientists determine those numbers? Scholars attempt to find the specific heat of a metallic element by using a calorimeter. Three experimental trials ensure accuracy, and analysis...

In this elements worksheet, students use a data table to graph the elements and their melting points. Students have eight elements to graph.

Light a fire in your pupils! Scholars conduct a flame test and observe the emission spectra of several different salts in an enlightening hands-on investigation. They use their observations to make comparisons and conclusions about the...

Students complete two graphic organizers in this ionization worksheet by filling in the proton number for given elements. Then, they create two graphs plotting the first ionization energy against the proton number.

In this elements instructional activity, high schoolers complete a graphic organizer by comparing the elements' melting point, boiling point, density, and electronic configuration. Students determine the characteristics of Group 7...

For this instructional activity about elements, students review the electron configuration of given elements and then complete the electron diagrams for the transition metal elements. This instructional activity has five problems to solve.

In this elements learning exercise, learners complete two graphic organizers by comparing the element symbol and melting point for given elements. Then learners plot a graph of their atomic radius against proton number.

In this elements activity, students complete a graphic organizer by filling in the symbol and atomic number for the given elements. Students plot a graph of melting point against atomic number. Students write the electron arrangements...

In this elements instructional activity, students complete a graphic organizer comparing lithium, sodium, and potassium observations. Then, they determine how these elements react with water. Students complete three fill-in-the-blank...

During this lab activity, chemists discover the reactivities of chlorine, bromine, and iodine as examples of the halogens. They use a displacement reaction as a test by adding other compounds and observing for a color change. The lab...

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.

In this compound instructional activity, students complete a graphic organizer by combining positive and negative ions appropriately and writing down the resulting compound.

Time to put the knowledge to the test! Young scholars take what they know about the periodic table and build their own from scratch. Using clues from 26 different elements, they place elements in a blank periodic table. The clues include...

Compounds take on different properties than their elemental components. How can scientists determine those elements? A lab-based activity has learners explore several double replacement reactions to analyze compounds qualitatively. They...

Sometimes modeling is the best approach to working with microscopic particles. A lab investigation models a fictional element using pasta. The setup uses three different pasta types to represent three different isotopes. Learners...

As the most abundant element on the earth, hydrogen requires no replacement. Yet scholars learn to replace hydrogen with a metal to liberate the hydrogen gas. A simple procedure and data table include the necessary information and...

For this compounds learning exercise, high schoolers identify molecules as compounds and provide a reason why they believe it is or is not a compound. Students write out chemical formulas. This learning exercise has three problems to solve.

For this atoms worksheet, high schoolers compare sub-atomic particles' position, relative charge, and relative mass. High schoolers define mass numbers and atomic numbers. This worksheet has two graphic organizers and four short answer...

In this electron arrangement activity, students complete two graphic organizers by determining the proton number of given elements from their first ionization energy. Then, they plot graphs of the first ionization energy against the...

No practice problems are given on this handout; it is a detailed list of concepts to know and tips for working related problems in chemistry. Give this to learners as a study guide, or use it early in your career as a chemistry...

Crazy fact—freezing liquid actually gives off heat! Young scholars investigate the transfer of energy when liquids freeze using a chemical heat pack. The heat pack gives off heat as its liquid core freezes.

Don't overreact! A simple experiment demonstrates chemical reactions as scholars mix chemical solutions and metals in a large well plate. They note all changes to the metals, solutions, precipitate, colors, and more. A full data table...

We know about the light spectrum, the age spectrum, and sound spectrum, but do chemical reactions also occur on a spectrum? Young scientists experiment with partial reactions on a spectrum and observe the color changes. Then, they...

Processed foods use inorganic compounds for flavoring and preservation. This take-home laboratory challenges scholars to find 20 different compounds identified on the labels of foods to list on their data collection sheet. The activity...
