Students will be able to explain the concept of combustion-burning of materials.
Students investigate the products of a combustion reaction. Students will learn tests to identify gases.
As students are learning about substances, mixtures, and solutions, they will participate in several experiments that involve chemical reactions using regular household products. Some experiments will produce gas or create something that will grow. Students will work in groups of 2-3 students to make a car move using the result of a chemical reaction from combining two or more household substances. They will present their project to the class.
A marching band, playing plucky marching music, acts out the chemical interactions and processes of the Krebs Cycle on a football field. The video shows the band footage with super-imposed computer-generated animation of the Krebs Cycle to supplement the marched representation.
From a bird's eye view, a marching band plays plucky marching music while acting out the chemical interactions and processes of the Krebs Cycle on a football field. Individual members and couples run into and out of the video frame to represent the entering and exiting of chemicals and enzymes.
A marching band, playing plucky marching music, acts out the chemical interactions and processes of the Krebs Cycle on a football field. Various camera angles are used, some from a bird's eye view, some at eye-level. Digital animation of the chemical reaction supplements the marching band's representation for additional clarity.
The chemical equation used to illustrate the chemical reaction that takes place in photosynthesis includes carbon dioxide, water, light, glucose, and oxygen.
As the temperature increases in this burner, particles move faster, which forces reactants to collide and react more frequently.
Students will develop a model of combustion showing that mass does not change in the process.
