Upcoming chemists construct atom or molecule models out of candy. This is a classic idea that learners really enjoy; however, this lesson plan is vague. There is no instruction about the structure of atoms or molecules. Make sure you...

Because of the work of John Dalton, we are able to write formulas for compounds. The hands-on experiment has scholars prepare a compound from its elements. Using mass data, individuals write the empirical formula for the compound.

What's the difference between a rock and a mineral? And what properties are used to identify minerals? The first installment of a five-part series on earth materials and processes prompts young scientists to identify a set of...

Students observe the 'pouring' of a gas. They compare the masses (weights) and densities of two gases. Pupils define the following terms: matter, mass, and density. Students answer questions after watching the demonstration.

Students are introduced to the mole concept using a discovery-based method. Lesson includes activities with candy that allow students to discover the rules for mole-item, item-mole, mole-mass, and mass-mole conversions.

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...

Students practice drawing the atomic structure of several different elements. They complete critical thinking questions about atomic structure and compare the atomic mass units for different ions and isotopes of an element.

In this math worksheet, students find the solutions to the problems that apply the time-independent Schrödinger equation. They examine the relationship between the mass and energy.

Students examine how nuclear reactions differ from other chemical reactions they have studied. They add up atomic masses of both the product and reactant side of an example of uranium decomposition, demonstrating mass loss involved.

In this periodic table worksheet, students answer 10 questions about the periodic table, the elements in the periodic table, the properties of elements and the atomic number, symbol and name of elements in groups of the periodic table.

Students investigate moles and Avogadro's hypothesis. In this moles lesson plan, students complete a worksheet by finding the volume of 1 mole of each substance given its density and they find the number of molecules, the formula, the...

Students explore what causes differences in density. They observe an models depecting atoms, compounds, and molecules. Students determine if there is air in between atomic bonds. They study the structure and spacing of molecular bonds.

High schoolers diagram nuclear power plant, describe process for generating electrical power, discuss nuclear disasters in the 20th century, and draw conclusion about value of nuclear power for the future.

Students identify the general atomic structure of an element represented on the periodic table. They examine bean and rice patterns that have been created by the teacher and posted around the room and then attempt to match the periodic...

Learners work in small groups with a small set of 8 nuts and 5 bolts to assemble into combinations of 1 nut: 1 bolt, and 2 nuts: 1 bolt. They explore the outcome and discuss. Then a student mixes two clear, colorless solutions together...

Students review atomic structure and then participate in a activity in which they categorize several "elements" into some form of order based on their properties. They discuss the trends they see. They also practice several electron...

Learners examine what radon is and which isotope it belongs. They discuss the characteristics of isotopes in general and the atomic number. They complete a worksheet to complete the lesson.

Learners collect evidence to make inferences about a object hidden inside a sealed box. They think critically and logically to raise questions. Students identify questions that can be answered through investigation. They formulate and...

Students 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.

Pupils consider the causes of density at a microscopic level. They then discover that one cause of density has to do with how many protons and neutrons the material contains.

In this chemistry worksheet, students use the periodic table of elements in order to identify the common elements. The detail is very detailed.

Students conduct research of the history of atomic theory. Information is presented from Democritus and Aristotle to the early Renaissance using the Internet and video.The integration of technology allows for a vast amount of research...

Students intergrate science, technology and society into exploring the periodic table. They investigate one element of their choice and write a one page paper on the elements discovery, properties, uses, and the effect on society.

In this chemistry worksheet, students examine the concepts of mole and molarity in order to apply in the laboratory setting. The sheet includes in depth background information.
