One core component of the chemical engineering curriculum that the websitedoes not have CSB modules for is the Chemical Engineering (or Unit Operations) Laboratorycourse(s). These labs tend to focus on more practical “soft” and less theory-based skills usingcalculations and equations taught in lecture classes. As a result

In-and-out of class learning experiences during middle school and high school have also been foundto impact students’ decision to pursue a STEM major [17]–[24]. Yet, studies have found that Latinx students are less likely than other groups to participatein out-of-school activities or school-based extracurricular activities [25]–[29].

It's important to make sure that the vector is found by moving "down" from the z axis rather than "up" from our projection in the xy plane.Student 2 made direct connections between the physical model and an abstract symbolicrepresentation of the relationships. Going back to the example vector, we can use the following equations above to get the unit vector. Figure 2. Image from Student 2’s response So why exactly is the unit vector so useful? One of the characteristics of a unit vector is that when you multiply it with a
