Grade Level: 6 (5-7)
Choose From: 3 lessons and 3 activities
Subject Areas: Chemistry, Physical Science
SummaryThrough three lessons and their four associated activities, students are introduced to concepts related to mixtures and solutions. Students consider how mixtures and solutions—and atoms and molecules—can influence new technologies developed by engineers. To begin, students explore the fundamentals of atoms and their structures. The building blocks of matter (protons, electrons, neutrons) are covered in detail. The next lesson examines the properties of elements and the periodic table—one method of organization for the elements. The concepts of physical and chemical properties are also reviewed. Finally, the last lesson introduces the properties of mixtures and solutions. A comparison of different mixtures and solutions, their properties and their separation qualities are explored.
Engineers apply their understanding of the properties of matter to decide what materials to use when creating and designing new things. And, they use their knowledge of mixtures and solutions when designing new synthetic materials for a multitude of purposes. Imagination has no bounds, and as technology advances and researchers learn more about the building blocks of matter, innovative technologies move from imagination to reality.
Engineers understand the properties of metals, whether they may bend or not bend, expand, contract, or withstand forces under certain circumstances—all important factors to consider when designing and creating the devices, structures and human-made objects we depend upon. Furthermore, engineers take advantage of the chemical properties of different elements as they develop mixtures and substances for medicines, materials and cleaning solutions, among the thousands upon thousands of other products that we use in our lives every day.
Each TeachEngineering lesson or activity is correlated to one or more K-12 science,
technology, engineering or math (STEM) educational standards.
All 100,000+ K-12 STEM standards covered in TeachEngineering are collected, maintained and packaged by the Achievement Standards Network (ASN),
a project of D2L (www.achievementstandards.org).
In the ASN, standards are hierarchically structured: first by source; e.g., by state; within source by type; e.g., science or mathematics;
within type by subtype, then by grade, etc.

Students examine the periodic table and the properties of elements. They learn the basic definition of an element and the 18 elements that compose most of the matter in the universe. The periodic table is described as one method of organization for the elements.
Students learn about atoms and their structure (protons, electrons, neutrons) — the building blocks of matter. They see how scientific discoveries about atoms and molecules influence new technologies developed by engineers.
Students use gumdrops and toothpicks to make lithium atom models. Using these models, they investigate the makeup of atoms, including their relative size.
