END OF THE UNIT COMPETENCY WITH LANGUAGE SUPPORTS

Standard 3.6 What does it look like to demonstrate profciency on this standard? Articulating the explanation of phenomena Students construct an explanation that includes: ● The idea that as kinetic energy increases, the reaction rate increases because the force and number of collisions between particles increase ● The idea that as concentration increases, the reaction rate increases because there are more particles to collide ● The idea that as particle size decreases, the reaction rate increases because the surface area available to react (more places of contact between particles) is greater ● The idea that when a catalyst is added to a reaction, the reaction rate increases because the activation energy is lowered Evidence Students identify and describe the evidence to construct the explanation, including:
