In this chemistry science worksheet, students identify the parts of a chemical reactions. Students name the major particles of the atom. Students apply knowledge about the atom, theories, and models.

For this elements worksheet, students determine how electrons fill up the energy levels for the first 18 elements of the periodic table. Students determine if elements gain or lose electrons to form a stable ion. This worksheet has 4...

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 learning exercise, 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,...

Students study hydrocarbon gases and chemical equations. In this hydrocarbon gases lesson, students work in groups complete a molecular formula worksheet and review alkane prefixes. Students complete molecular models, balance chemical...

High schoolers will draw Lewis structures of common covalent compounds using a Chem 3D computer program. They will predict the shapes of the molecules, complete a data table, and formulate rules for predicting shapes of molecules. In the...

Students define and read an article on polar energy.  In this polar energy lesson, students answer questions about the article.  Students participate in activities related to isotopes, half-life and radiocarbon.  Students...

Young scientists observe the spectra of elements and compare that to the Doppler effect. Hook scholars from the beginning all the way to the extension activities in this 5E-format lesson. 

Students use models to visualize molecular structures. Students read about Lewis dot structures, hybridization, and formal charge. Then students build and draw the molecules and ions given. Students complete 11 pre-lab questions and 4...

In this atom worksheet, students will complete 8 fill in the blank statements based on the different parts of an atom. Then students will explain how the arrangement of electrons in an atom is related to the periodic table.

In this physics worksheet, students review vocabulary terms and key equations associated with the quantum mechanical model. Students apply the quantum theory to explain the photoelectric effect. This worksheet has 5 true or false, 12...

Students work together to observe the bond lengths of single, double and triple bonds. They make their own predictions about the strength of the bonds and chemical reactions. They answer discussion questions to complete the lesson.

Learners practice drawing Lewis dot structures, build molecules with model kits, and predict molecular shapes using VSEPR theory. The combination of written work and hands-on reinforcement benefits young scientists.

Trace the sequential process of the developing theories of atomic structure in the early 20th century, show, in historical development, how scientists "know" things, how experiments are set up and how interpretations are drawn from them,...

Middle schoolers examine the concepts of isotopes and atoms.  In this powerpoint lesson, students see the balance in numbers  of protons, neutrons, and electrons create isotopes and ions of certain atoms.

Students collect and analyze data to study wavelengths of visible light. They cover Styrofoam cups with three different colors of sun filtering products and shine a lamp directly on the cups. They determine the most effective filtering...

A complete overview of oxidation, reduction, and how electrons are moved in respiration. You could use this slide show to elaborate on the concept of harvesting stored energy, and to summarize the stages of aerobic and anaerobic metabolism.

In this honor chemistry I worksheet, students use all available resources to answer each question given. Students apply their knowledge of light, quantum theory of light, Bohr's model, photoelectric theory.

Pupils design and conduct an experiment to investigate what happens when salt and ice come together and to determine if one form of salt is better for melting ice on steps and sidewalks.

In this review for chemistry worksheet, students decide if given statements are true or false. Students relate information learned about introductory knowledge gained in chemistry to accurately answer the given questions.

High schoolers create a model of a column of air and discover one of the reasons why low and high pressure systems exist and why low pressure is often associated with bad weather.

Eighth graders draw the structure of an atom. They construct atomic models, list parts/locations of an atom, organize parts of the periodic table and write a descriptive report about an element.

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.
