After challenging themselves to correctly choose the form of erosion and length of time required for a given landform to develop, earth science class members model mechanical and chemical weathering with various lab demonstrations over...

In this atoms learning exercise, 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...

Students investigate how information about the atom has been determined. In this atomic structure lesson, students draw what they think an atom looks like. They conduct Internet research about the types of atomic models and how...

Students study the particles of which atoms are made. They define the electron, proton, and neutron and their attributes.

Learners examine how scientific theories are developed. In this matter instructional activity, students explore the basic idea of quantum theory. They create a timeline of scientists, their contributions, and discoveries.

In this atoms activity, students explain why the moles is used as a counting unit for atoms and determine the molar mass of given elements. This activity has 3 short answer and 4 fill in the blank questions.

In this scientific investigation worksheet, students follow the provided procedures to examine the chemical reactions of hydrogen and oxygen atoms and then respond to 1 short answer question.

In this elements learning exercise, students write the electron configurations for given elements. Students describe ionization energy and electron affinity and the periodic trends for both. This learning exercise has 20 short answer...

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.

For this atoms worksheet, high schoolers compare sub-atomic particles' position, relative charge, and relative mass. High schoolers define mass numbers and atomic numbers. This worksheet has two graphic organizers and four short answer...

Young scholars study atoms and chemical compounds. They identify certain elements essential to human health, describe physical and chemical properties of water, and name four types of polymers unique to all life forms. They explain how...

Students examine the differences between elements, compounds and mixtures. Using diagrams, they compare and contrast atoms and molecules and describe various chemical reactions. They distinguish the differences between ionic and...

Pupils explore the concept of atoms and how they combine to form molecules and compounds. In pairs, they read an article on how atoms work and discuss the main points. They draw atoms and write a paragraph about their elements.

In this chemistry worksheet, students find the words that are related to atoms and molecules. The answers are found by clicking the link at the bottom of the page.

In this chemical bonding worksheet, students review the different types of bonds and calculate the number of valence electrons in molecules. This worksheet has 11 matching and 15 multiple choice questions.

In this matter worksheet, students review the three forms of matter by reading a poem and completing 1 matching and 5 short answer questions.

In this chemistry instructional activity, students study the composition of the elements in the periodic table using an interactive website.

In this classification of changes worksheet, learners identify each example as either chemical or physical changes. Students also classify other examples as either element, compound, solution, colloid, or suspensions. In the other...

An online resource, this worksheet has your chemistry learners complete four data tables with information about atoms and chemical bonds. The first table addresses atomic number and mass, as well as numbers of protons, neutrons, and...

Students explore ionic bonding. They draw examples of ionic bonding and explain the activities of the electrons of the elements. Students use paper plates and candy to draw electron configurations of given atoms.

Third graders study the concept of light as an energy source.  In this energy lesson students participate in a lab that show them the concept of light as an energy source. 

In this countdown challenge worksheet, students find the 10 common elements from the human body, earth's crust, and ancient times and color code them. Students fill the atomic number of the elements in a given periodic table.

All you will find in this resource is a list of vocabulary terms dealing with chemical bonds. Space is provided for chemistry learners to write out definitions. This would be a terrific tool to help prepare them for a quiz.

Although biochemistry of the human body is a vital topic, it doesn't have a chapter dedicated to it in many biology textbooks. If that's the case with your text, you can use this resource as a guide for designing your own lecture and as...
