In this interactive activity from ChemThink, learn how ionic bonds are formed and how an ionic bond structure is represented by its formula.

In this video segment adapted from NOVA scienceNOW, students will follow scientists in their quest to understand how stable elements are made and how to create the elusive element 114.

Learn about the elements used to create the spectacular colors seen in firework celebrations. Color your own firecracker, then use paper and a straw to design a system to launch your firework.

Students measure the relative intensity of a magnetic field as a function of distance. They place a permanent magnet selected distances from a compass, measure the deflection, and use the gathered data to compute the relative magnetic field strength. Based on their findings, students create mathematical models and use the models to calculate the field strength at the edge of the magnet. They use the periodic table to predict magnetism. Finally, students create posters to communicate the details their findings. This activity guides students to think more deeply about magnetism and the modeling of fields while practicing data collection and analysis. An equations handout and two grading rubrics are provided.

Through 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.

Explore the elements found in the Periodic Table of Elements and what role some of them play in the universe. Test your knowledge of the elements and the organization of the table by completing a puzzle.
