Students will enter the classroom and be handed a card with the name of an element on it. They will then have to find the desk with the corresponding element number and name and sit at this desk. Each student fills out a Student...

Students research the history and uses of the different elements in the periodic table. In this chemistry activity, students explain the significance of an element's valence electrons. They create a multimedia presentation of an element...

In this oxidation numbers worksheet, students determine the oxidation number for given elements and draw Lewis Dot Diagrams. This worksheet has 6 fill in the blank and 11 short answer questions.

Students identify the elements that belong to the halogen family on the periodic table. For this chemistry lesson, students describe the common characteristics of elements in this group. They research about hydrochloric acid's effect on...

Students investigate the structure of the atom and its composition. In this atom structure lesson, students find the area of cut out circles and drop pens into the circles. They count the number of marks in the circles and relate their...

In this atomic trend worksheet, students answer questions about trends in the periodic table such as ionization energy, atomic radii and electronegativity. They are given tables of elements and ions and they must identify which ones have...

In this atom worksheet, students fill in three charts using the periodic table to identify atomic number, atomic mass, number of subatomic particles and the element's symbols. Students draw an atom and it's subatomic particles as well as...

Eighth graders explain what makes up matter.  In this atoms activity students define an atom and what its components are and identify properties of elements. 

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

In this chemistry activity, students learn about matter, including atoms, electrons, protons, neutrons, compounds and chemical properties. They use this information to answer the 10 questions on the activity. The answers are on the last...

In this chemistry worksheet, students describe an atom, its parts, the charges of these parts, and atoms life functions. Then they explain what the octet rule states for the placements of electrons around the nucleus of an atom. Students...

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

Students describe how elements are arranged in the periodic table. They compare metals, nonmetals, and metalloids based on their properties and on their location in the periodic table. Finally, students identify and describe the...

Students identify the concept of an element and work with an idea that all of the millions of substances on the earth are various combinations of only 8 elements. They work with the Periodic Table of the Elements and symbols of the...

Ninth graders review and discuss the Periodic table and its 53 elements. They choose one element to become an expert on and then create a written Report in the form of a poster about their choosen element to be presented to the class.

Students perform varied activities as part of a layered curriculum unit: They write and perform a skit that outlines the evolution of the model of the atom. The script is submitted to the teacher for review before performance.

Students explain the mole concept and use this concept to prepare chemical solutions of particular molarities.

In this chemical compounds worksheet, students determine is compounds will act as acids or bases when added to water. Students compare basic, acidic, and amphoteric anhydrides. This worksheet has 15 fill in the blank, 2 short answer...

Students research about the chemical processes involved in cave formation. For this chemistry lesson, students draw or find a cave picture with stalagmites and stalactites online. They write a brief caption and share them with the class.

In this Bohr model instructional activity, students draw 16 diagrams given atoms in the periodic table and must show the energy level diagrams indicating the electrons in each energy level.

A short slide show to display the characteristics of group 13 on the periodic table of elements. The atomic structure and reasons for their physical and chemical characteristics are not explained, and so this would only be an...

Words, words, words! This presentation uses plenty of them to define the atom, outline the history of what we know about atoms, and explain atomic and mass numbers. That's all! Informative, but not interesting, this slide show would be...

In this atoms worksheet, students use their knowledge of the periodic table and of atomic structure to complete the table on atoms. They identify the notation for each and then the atomic number, mass number, the number of protons,...

In this drawing Lewis structures worksheet, learners read about the 5 steps taken to draw Lewis structures for atoms and molecules. These include identifying the valence electrons, placing pairs of electrons between atoms to be bonded,...
