 +  * **[[swbq:vcsw:vfswsurface|Drawing Surfaces in Cylindrical and Spherical Coordinates]]** //(Estimated time: 5 minutes)//: In this sequence of small whiteboard questions, the students are asked to draw surfaces of equal values of coordinates in cylindrical ($s$, $\theta$, and $\phi$) and spherical coordinates ($r$, $\theta$, and $\phi$). This can lead into a whole class discussion on the range of values allowed for each coordinate in cylindrical and spherical coordinate systems.

 +  * **[[courses:activities:vfact:vfbasisvectors|Curvilinear Basis Vectors]]** //(Estimated time: 15 minutes)//: In this kinesthetic activity students are asked to point in $\hat{r}$, $\hat{\theta}$, $\hat{\phi}$, $\hat{s}$, and $\hat{z}$ directions in reference to an origin within the classroom. A class discussion ensues about the directions of curvilinear basis vectors and how the direction changes at different points in space. This is in contrast to rectangular unit vectors, $\hat{x}$, $\hat{y}$, and $\hat{z}$, which have fixed directions at each point in space. Many mathematics courses do not cover curvilinear basis vectors, so it is expected that students will not be familiar with these basis vectors.

 +  * **[[courses:lecture:sylec:drintro|Introducing $d\vec{r}$]]** //(Estimated time: 5 minutes)//: This mini-lecture introduces the $d\vec{r}$ in terms of rectangular coordinates. This lecture can be used to introduce the [[courses:activities:vfact:vfdrvectorcurvi|dr in Cylindrical and Spherical Coordinates]] activity which finds $d\vec{r}$ in those coordinates.

  * **[[courses:activities:vfact:vfpumpkin|Pumpkins and Pineapples]] and [[courses:activities:vfact:vfdrvectorcurvi|dr in Cylindrical and Spherical Coordinates]]** //(Estimated time: 30 minutes)//: These small group activities have students find $d\vec{r}$ in curvilinear coordinates by using pumpkins and pineapple slices to construct volume elements while determining how to construct $d\vec{r}$ in curvilinear coordinates. This activity is intended to introduce students to small changes in each coordinate direction.
