In this atoms worksheet, students answer four different sets of questions related to atoms (fill in the blank, multiple choice, word puzzle and true and false).

In this molecules worksheet, students answer post lab questions about types of bonds, factors that determine polarity and molecular geometry. They calculate electronegativity differences in atoms and determine the types of bonds between...

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

In this biochemistry instructional activity, students complete a table by filling in the missing information about different elements. Students draw the Bohr diagram and the Lewis dot diagram for several atoms.

Students examine the structure of molecules, their formula, and percentage composition of each element in the compound. They construct an organic compound with different functional groups using a modeling kit, and draw a 3-D structure...

Learners study atoms and their protons and neutrons.  For this physical setting lesson students work together to complete a lab activity. 

For this atoms worksheet, high schoolers review the parts of an atom, Bohr diagram, atomic number, mass number, and covalent bonds. This worksheet has 5 drawings and 26 fill in the blank questions.

In this chemical formulas activity, students practice naming molecular compounds by their formulas and determine if a gas is a compound or an element. This activity has 13 fill in the blank questions.

Students write the electron configuration of elements in the ground state. In this chemistry lesson, students draw how subatomic particles are arranged in the atom. They construct Lewis dot diagrams of valence electrons.

Students act out different types of circuits, and create their own circuits using wire, a bulb, a battery and a switch.

Students investigate the concept of a polymer using an experimental design of protecting an egg in a bookbag. They test the properties of polymers and form an educated solution to the proposed problem. Then they describe the steps used...

Young scholars understand the evolution of the atomic model from Ancient Greece to the present. They then choose one of the options as a project using class time to do research and to be creative.

Students predict the shape of molecules using VSEPR theory. In this chemistry lesson, students differentiate a polar and nonpolar molecule. They discuss why water's polarity is very important.

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

Seven practice problems are presented to physics pros in this assignment. Given the wavelengths, they perform computations for emission spectra. This brief worksheet makes an appropriate pop quiz.

First graders in kindergarten science class discuss matter. They make predictions and then identify mystery items in brown paper bags as either solid, liquid, or gas by using their senses. They discuss that a chemist is a scientist that...

In this paragraph correction learning exercise, students read an 8 line passage. Then students respond to 8 multiple choice questions regarding grammar, punctuation, and spelling errors within the paragraph.

Students build atoms of elements 1-20. The entire set can be hung from the ceiling in order of the Periodic Table to be referred to throughout the Chemistry class/unit. This is helpful when teaching bonding and patterns of the Periodic...
