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

Students identify the scientist who first wrote the Periodic Table, identify the scientist who amended the Table, state (or write) specific data relating to the history of the Periodic Table, identify at least five elements, and two...

Students describe properties of various elements. They arrange the elements based on properties in order to explain the organization of the periodic table. They label elements as metal, non-metal, or metalloid.

Students explore the molecular structure of matter and how it can affect the physical characteristics of a specific material. They investigate the role carbon plays in the chemistry of life.

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

Learners determine the average mass of a new element using masses from three isotopes. In this chemistry lesson, students explain what an isotope is. They discuss their importance and uses.

Students explain how elements are arranged in the periodic table. In this chemistry lesson, students group the eggs according to a certain pattern. They compare this to elements in the periodic table.   

Pupils identify the different periodic trends. In this chemistry lesson, students discuss how elements are arranged in the periodic table. They apply what they have learned in a Jeopardy team game.

Students explain how radioactive decay occurs. In this physical science lesson, students simulate radioactive half-life through an experiment. They graph their data and share their results in class.

Students read stories from a robot journal.  For this robot lesson students complete definitions and several activities, including a short essay. 

Students identify the elements of science fiction and write their own example.  In this Journey to the Center of the Earth instructional activity students complete several activities about science fiction, authors and novels.

In this elements learning exercise, students review the periodic table and how the elements are organized in the periodic table. This learning exercise has 5 short answer and 4 fill in the blank questions.

In this Earth's crust worksheet, students determine the most abundant and least abundant elements in the atmosphere, oceans, and crust. This worksheet has 1 fill in the blank and 11 short answer questions.

In this atoms instructional activity, students determine an atoms based on its protons, and neutrons. Students determine the electron levels for the oxygen atom. This instructional activity has 1 multiple choice, 4 fill in the blank, and...

In this elements learning exercise, students review the Bohr model and define negative and positive subatomic particles. Students compare molecules and compounds. This learning exercise has 11 short answer questions and 4 problems to solve.

In this compounds worksheet, students compare ionic, covalent, and polyatomic compounds and give examples of each type. This worksheet has 1 matching, 3 problem solving, and 4 short answer questions.

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.

In this elements worksheet, students determine if the given elements are metals or nonmetals. Students give the valence electrons for other elements. This worksheet has 10 fill in the blank questions.

For this matter worksheet, learners compare and contrast chemical and physical properties and explain the relationship between a pure substance and a mixture. Students review the properties of metals and nonmetals. This worksheet has 1...

In this compounds worksheet, students compare separating elements of a compound and substances in a mixture. Students review melting and boiling point. This worksheet has 1 fill in the blank and 5 short answer questions.

In this periodic table worksheet, students write the chemical symbols for the given elements, compare atomic number and mass number, and describe the importance of valence electrons in the organization of the periodic table. This...

In this elements activity, students determine the pattern that is being illustrated by the diagrams of the periodic table. Students identify 6 different patterns.

In this creating bonds worksheet, students create 2-D and 3-D models of the molecular formula provided. Students complete a chart of information about the molecular formula given.

In this chemical compounds worksheet, students write the name or chemical formula for the given compounds. Students determine the mass of a cylinder and a given volume of ethanol. This worksheet has 2 fill in the blank questions and 2...
