Watch budding chemists interact with the resource on chemical interactions. In the unit, six lessons provide an overview of basic chemistry, from understanding the development of atomic theory to distinguishing between ionic and covalent...

Everyone enjoys combining baking soda and water. Here is a lesson that challenges scholars to analyze the reaction three different ways — the real substances, the chemical equation, and the molecular models. Class...

Nanofibers can be made through electrospinning or force spinning in order to reduce the negative impact on the environment. Pupils study the role of fibers and dye on the environment through a series of five hands-on activities. Then,...

Some like it hot! Scholars observe both exothermic and endothermic reactions as part of the carbon dioxide oxygen cycle. First, scientists demonstrate (or watch) a chemical reaction to create pure oxygen using fire for...

The liquids did not mix — so what do density columns have to do with it? The seventh part in a series of nine provides the theoretical explanation of why density columns do not mix. The lesson plan covers the topics related to...

An in-depth lesson, the fourth activity in a series of 36, begins with teaching how the periodic table's arrangement came to its current design. Using this knowledge, pupils then move on to analyze the arrangement of elements to their...

Energize biologists with colorful images in an activity that captivates the imagination while demystifying the subject of cellular respiration. Participants build comprehension skills and access core content knowledge by analyzing text...

Young chemists grow ionic crystals, metallic crystals, and supersaturated crystals in three different lab experiments. Observing these under a microscope allows pupils to compare the various structures. 

Learners explain historical findings such as Rutherford and Bohr's contributions, explain wave particle duality, and formulate Heinsenberg's uncertainty principle. They also draw s, p, and d orbitals, explain more historical findings,...

All life requires energy ... and the connection between energy and plant life typically requires photosynthesis. Scholars explore photosynthesis in depth from ATP/ADP through the Calvin cycle. A helpful presentation highlights concepts...
