In this atom worksheet, students read about the structure of the atom including its subatomic particles and John Dalton's theory of the atom. Students also read about the differences between atoms, molecules and compounds. They answer 30...

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 compounds worksheet, students are given a bag of colored gumdrops that represent specific atoms. They construct ionic and covalent bonds with gumdrops using the key provided and the compounds to build. They fill in a chart with...

This comprehension worksheet provides readers with an article about basic matter and then asks them to use this information to respond to a series of comprehension questions.

Bacteria outnumber all other forms of life on Earth. Scholars observe the growth of bacteria in petri dishes to understand their role in maintaining good health. Then, they observe the growth of bacteria after they introduce...

By measuring the wavelength, frequency, and intensity of electromagnetic radiation, scientists determine the temperature, density, and composition of far away items. Scholars rotate through ten lab stations using a spectroscope at each...

When an organism eats, how does food become energy? Young biologists follow glucose through the process of cellular respiration to the creation of ADP using a discussion-based activity. The resource also highlights conservation of mass...

Combine mathematics and science to calculate measurements of unmeasurable materials. Individuals use knowledge of density and volume to determine the thickness of the film used in production. They also apply stoichiometry to...

Students observe 3 models that show Dalton, Thomson and Rutherford's theories of the structure of the atom. In this structure of the atom lesson plan, students observe each model and write a summary of each theory of the atom.

Students construct models of the way water molecules arrange themselves in three physical states - solid, liquid, and gas. They explain the molecular behavior of ice, water, and water vapor.

Students simulate how scientists studied things they can't see like atoms. In this chemistry lesson, students predict what is inside the numbered obsertainers. They design a way to investigate what's inside without opening it.

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.

Lead your class through the amazing world of isotopes as they investigate the various properties they contain and further understand their respective location on the periodic table. They explore half-lives and radioactivity as each...

Does it feel a little humid in here? Learners assume the role of water vapor in the atmosphere as they explore the differences between warm and cold air. They roll dice to determine their level of energy, which determines if they...

Young scientists create a simulation of Hubble's law. Introducing the Big Bang Theory using balloons and a simple lab instructional activity, scholars complete a data table and perform analysis.

The reintroduction of a species to an area doesn't always go as expected. Scholars learn about the reintroduction of wolves into Yellowstone National Park with a video, reading, and discussion questions. They complete a hands-on activity...

Students examine the atomic structure of elements.  In this chemistry lesson students organize elements of the periodic table according to their atomic mass, and compare their order within the periodic table. 

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 minerals worksheet, students read about the relationship between elements, rocks and minerals. They experiment using 6 different colored gumdrops to represent 6 common elements. Students construct gumdrop and toothpick models of...

Seventh graders, in groups, complete an Isotopes model and notice that atomic masses are decimal numbers. These masses are an average of all the isotopes of that element.

In this biochemistry worksheet, 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 brainstorm what matter is and how they define it. They construct a water molecule with marshmallows and toothpicks. In addition, they watch videos to explore the use the idea of nanoscience to investigate the properties of...

In this atoms worksheet, students circle the term in parentheses that makes the 20 statements correct. The statements review the parts of an atom, isotopes, and basic matter principles.

In this atom worksheet, young scholars define the atomic theory, compare an atom and a molecule, determine atomic number and number of protons for elements, and draw Bohr models for given elements. This worksheet has 4 graphic organizer,...
