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 instructional activity, students explain the significance of an element's valence electrons. They create a multimedia presentation...

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

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

Students identify the different periodic trends. In this chemistry instructional activity, 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 plan, students simulate radioactive half-life through an experiment. They graph their data and share their results in class.

Learners 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 lesson students complete several activities about science fiction, authors and novels.

In this elements instructional activity, students review the periodic table and how the elements are organized in the periodic table. This instructional activity 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 worksheet, students determine an atoms based on its protons, and neutrons. Students determine the electron levels for the oxygen atom. This worksheet has 1 multiple choice, 4 fill in the blank, and 13 short answer questions.

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

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

For this oxidation numbers worksheet, learners 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, learners 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.

In this matter learning exercise, students 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 learning...

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 worksheet, 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 instructional activity, 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 instructional activity has 2 fill in...
