Registering for Summer 2021?

Both BIOL 1020 and BIOL 1021 run concurrently from June 3rd – August 27th.

Synchronous Sessions (Optional)

Sometimes it’s just easier to ask a question or get some help in real time. Synchronous sessions are conducted on Collaborate Ultra, are not mandatory, and are not recorded. The schedule for synchronous sessions is included with the course schedule on Brightspace. If you can’t attend a synchronous session, you may make appointments to meet with an instructor or teaching assistant at other times.


All assessments (quizzes, labs, exams) are conducted online. There are weekly quizzes, biweekly labs, and and one summative exam per unit (three exams in total).

Assessment details are included in the syllabus and on Brightspace.

Take Dalhousie’s introductory biology courses online

Dalhousie’s Department of Biology offers online versions of its two introductory biology courses.

BIOL 1020 and BIOL 1021 may be taken by on-campus students to facilitate their work and study schedules, or by students at any location where regular access to the Web is assured.

Students may take a combination of the online and classroom-based courses (BIOL 1010 and BIOL 1011). BIOL 1020 is not a prerequisite for BIOL 1021, so the courses may be taken in any order.


BIOL 1020 and BIOL 1021 are offered concurrently in all three terms (Fall, Winter, and Summer). Each course is offered over approximately 13 weeks, during the regular Dalhousie term schedule. Each course starts with an Orientation period, followed by 11 weeks of course content.

Please note: BIOL 1021 (Intro II) will not be offered in Fall 2021; BIOL 1020 (Intro I) will not be offered in Winter 2022.


While these courses meet the prerequisites for further courses in biology at Dalhousie, they are not restricted to biology students or even to current Dalhousie students. Dalhousie arts students may wish to take the courses to fulfill their science requirement, and persons who are not currently registered at Dalhousie University can apply to Dalhousie as a visiting student. (For more information, see Undergraduate Admissions.) Once your application to Dalhousie has been processed, you can register for either or both courses (see Dalhousie’s Online Learning website). Students from other universities are reminded to obtain a letter of permission from their home institution in order to obtain credit for BIOL 1020/21 towards their degree program.

If you have never taken an online course before, you may wish to try the Are You Ready to be an Online Student? self-assessment quiz.


BIOL 1020 and BIOL 1021 are fully interactive, web-delivered courses. For each weekly lesson there is a reading assignment, a recorded lecture, a set of related activities or exercises, and an online quiz. The courses also include exams and labs. There are ample opportunities for students to communicate with their peers, teaching assistants, and instructor, via discussion boards, e-mail, and web conferencing. Instruction is primarily asynchronous, meaning that there are no set times that students are required to be online.

Unlike some distance education courses which are self-directed or “learn at your own pace”, BIOL 1020 and BIOL 1021 are highly structured. Their flexibility lay in the fact that students do not have to attend a lecture or lab on campus. Students should bear in mind that they are required to meet weekly deadlines, and to write the exams on their scheduled dates.
