Facilitate learning by using small objects to teach the principles of atomic mass in your science class. Pupils determine the average mass of varying beans as they perform a series of competitive experiments. They gather data and...

Students develop an understanding of the mole and molar masses of elements. In this mole lesson plan, students use beans to find their relative masses and draw parallels to the atomic masses of elements. Students work in teams and each...

What is it worth to you? A hands-on lesson asks groups to collect weights of different combinations of coins and calculate weighted averages. They use the analysis to understand the concept of an isotope to finish the third lesson in a...

High schoolers investigate relative mass using 8 different items. In this relative masses lesson plan, students discuss as a class John Dalton's atomic theory. They take the masses of the 8 items and record their data. They discuss...

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.

Explore the connection of surface area to bonding within atoms. Learners complete lab investigations to model changing surface area with different sizes and concentrations of atoms. A flour fireball demonstration follows the labs to...

It's electronic! Pupils uncover elements and their electron configurations as they explore mass, groupings, correct charges, and sliding theory. Young scientists learn creative ways to remember various elements and correctly...

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 are introduced to the periodic table. They find the common trends among the electron configurations and the names of certain groups of the table. Students explore the atomic mass, atomic number, mass number, mass and charge...

Students will discuss the de Brogile Hypothesis and state the circumstances under which the wave nature of matter is observed. They will also calculate the wavelengths of matter waves.

Space scientists investigate the cosmic phenomena in order to search for answers to possible origins of the solar system. They consider the concepts of elements and  isotopes. Data is analyzed looking at tje abundance of elements...
