The first nine slides visit the history of our understanding of atoms. The next several outline the structure of atoms. Subatomic particles, electron configuration, and diagramming methods are introduced. This is a neatly organized...

Making models is always memorable. In this activity, physical science starters examine the structure of hydrocarbons using marshmallows, raisins, and toothpicks. They even act as atoms themselves and link arms to represent covalent...

Students record information from the periodic table for sodium and chloride. They determine whether salts are molecular or ionic compounds, along with sodium chloride's molecular weight, and relative weights

A splendid chart of information about chemical bonding tops the first page. In it you will find information on London forces, permanent dipoles, hydrogen bonds, ionic bonds, and covalent bonds. A four-step process for assigning...

Teach the basics of mass spectrometry with a hands-on lesson. The fourth in a series of six lessons explores how mass spectrometry measures the ionic composition of an element. Learners then compare and contrast relative abundance and...

Experiment with mass and density as scholars figure out what makes things float or sink. First, they watch a podcast introducing these concepts. Be sure to use the comprehension question to test their understanding. Young scientists...

In this resources worksheet, high schoolers compare and contrast physical and chemical properties and changes. Students review the periodic table, pattern of atomic numbers and chemical reactivity. This worksheet has 56 short answer...

Students discuss the mass-energy relationship based on Einstein's work. They calculate the energy released in various scenerios and sketch diagrams for the Lyman, Balmer and Pfund Series. In groups, they discuss the role of photons and...

In this chemistry worksheet, students create new and true statements while replacing false ones in order to properly define parts of the concept of bonding.

In this chemistry worksheet, students examine the energy rule of moles and answer the essay questions. The answers are include with the worksheet.

Students explore the concept of molecular modeling and differentiate between saturated and unsaturated compounds. In small groups, they identify molecular formulas, complete a chart comparing alkanes, alkenes, and alkynes, and construct...

For this periodic table worksheet, students create cards for a annotated periodic table then use it to answer 16 short answer and fill in the blank questions.

In this science blackout vocabulary worksheet, students read the definition of 15 physics terms, then write the correct word.

In this length worksheet, students read about the properties of carbon. Students also decide which of the given phrases go with which compound.

Students investigate foods. For this biology lesson plan, students will conduct testing on different types of foods as they learn about different molecules that make them up. Students will also learn about the shapes of the molecules.

In this atoms worksheet, learners review protons, neutrons, electrons, molecules, compounds, and ions. This worksheet has 10 fill in the blank and 3 problems to solve.

Learners investigate the length of various objects. In this measurement lesson, students convert one metric unit to another. They explain the importance of a uniform system of measurement.

For this science worksheet, students choose the multiple choice answer that best defines each of 15 science related vocabulary words.

Ninth graders explore the molecular structure of matter and how it can affect the physical characteristics of a specific material. They demonstrate that isotopes of an element have different masses. Students demonstrate that the rates of...

In this science worksheet, students explore the learning outcomes for a unit on chemical reactions. Students define 60 vocabulary words and answer a list of questions for each topic.

Fifth graders study the properties of metals and use them to identify different properties.  In this metal properties lesson students complete a demonstration .

For this chemical reactions worksheet, students experiment with hydrochloric acid and copper (I) chloride to identify the types of reactions they undergo with various other substances. They also observe the law of conservation of mass...

Students study the difference between types of ionizing radiation and how elements are transmuted. They determine that radiation is normal and surrounds us. They calculate the amounts of alpha, beta and gamma radiation emitted from a...

Students determine crude oil can be separated into useful fractions by a process of fractional distillation. They write a balanced equation for the reaction between a hydrocarbon and oxygen.
