The Causes of Differences in Density
Young scholars 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...
Curated OER
Matter
Fifth graders investigate the structure of matter. They examine pictures of atoms and molecules and discuss their relationships, and construct a model of a molecule using toothpicks and gumdrops.
Curated OER
Elements and the Periodic Table
Learners are introduced to the elements on the Periodic Table and what is meant by element. Using the Table, they identify the name, atomic mass, number and symbol of each element. To end the lesson, they discover the characteristics...

Periodic Table Lesson Plan
Learners describe how elements are arranged on the periodic table. They compare metals, nonmetals, and metalloids based on their properties and on their locations in the periodic table. Students describe the differences between a...
Curated OER
Density
Students explore the meaning of density. In this density lesson, students use interactive whiteboards to review definitions regarding density and compare the density of selected objects.

Chemistry E3 Lesson Plan
Ninth graders perform a series of experiment to investigate heat transfer and phase changes. In this physical science lesson, 9th graders identify and calculate the different subatomic particles. They explain the importance of scientific...
Curated OER
Forces And Energy
Students investigate the atom and how it is formed. They conduct research using a variety of resources and then construct a model of the atom. Then students have class discussion. The lesson includes background information for the...
Curated OER
What is Radon?
Middle schoolers read an article about radon and its properties. They examine a periodic table and identify the numbers surrounding an element. They discuss the harmful and helpful effects of radiation.
Curated OER
What Is Radon?
Students 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.
Curated OER
Structure of the Atom
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.
Curated OER
Periodic Trends
Students identify the different periodic trends. In this chemistry lesson, students discuss how elements are arranged in the periodic table. They apply what they have learned in a Jeopardy team game.
Curated OER
Periodic Table Patterns using Fabulous Periodic
Students explain how elements are arranged in the periodic table. In this chemistry lesson, students group the eggs according to a certain pattern. They compare this to elements in the periodic table.
Curated OER
Finding the Spot
Fourth graders use circles to "home in" on particular spots, showing the ability of scientists to locate unseen objects in space. This activity shows how scientists know certain objects exist in space due to the forces exerted by...
Curated OER
Transformation of Energy
Sixth graders explore and discuss how several electrical devices work and what energy conversions occur in each device. They connect a zinc strip to a copper strip with alligator clips and wire, immersing each strip in lemon and check...
Curated OER
Popcorn Neutrino Lab
Students parcticipate in a modeling activity that simulates the cyclical role of experimental and theoretical science. Initially, students measure the mass of popcorn. They also record predictions of the mass of the kernels after they...
Curated OER
Organization of the Elements and Periodic Table
Students identify how to relate the position of an element in the periodic table to its atomic number and atomic mass. They also identify and interpret how to use the periodic table to identify metals, semimetals, nonmetals, and...
