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...

Uranium 235 has a half-life of over 700 million years and is the fuel used in the atomic bomb dropped on Hiroshima, Japan. Pupils see the half-lives and decay rates of Carbon-14 and Uranium-238. They also take measurements of these two...

Students classify materials. In this chemistry lesson, students examine the properties of solids, liquids, and gases. Students discover the elements, compounds, and chemical symbols.

For this elements worksheet, students determine how electrons fill up the energy levels for the first 18 elements of the periodic table. Students determine if elements gain or lose electrons to form a stable ion. This worksheet has 4...

In this conversion worksheet, students make the following conversions, showing each step. Students use the periodic table and express all molar masses to 1 decimal place.

In this chemistry science worksheet, students identify the parts of a chemical reactions. Students name the major particles of the atom. Students apply knowledge about the atom, theories, and models.

In this chemistry 301 worksheet, students answer questions as it relates to the electron configuration of given elements. Students use the periodic table to assist in their interpretation of the questions provided.

Students identify the different elements that belong to the Noble Gas family. In this chemistry activity, students design a neon sign. They research how they are made and share their work with the class.

Fourth graders, in groups, compile information on groups of elements. They study Alkali Metals, Alkaline Earth Metals, Halogens, and Noble Gases.

In this atomic structure worksheet, students use the periodic table to complete a chart for 11 elements/ions in terms of atomic number, number of protons, neutrons and electrons.

Gamification is an educational sensation! Young scientists build their acid-base vocabulary skills through a series of puzzles focused on bases and the salts they form. The challenging activity comes complete with a printable version and...

Many people confuse the chemical formulas for copper carbonate and copper oxide. A set of challenging puzzles review commonly confused compound names and their symbols. Through a series of four puzzles, pupils match the names and...

Students gain a perspective in the development of chemistry. They understand some of the topics in their text and the ongoing nature of research. They then will be able to see the trends of the periodic table first hand through their own...

Students discuss transition metals, their properties, and where they are located on the periodic table as well as why transition metals are ideal for coins. After discussion, they conduct an experiment using copper in the form of old...
