How can I create a safe lab experience for my students? How will I have time to sanitize everything in my lab before and after each class? Do I have enough personal protective equipment (PPE) at my school? What is the best way to engage my students when they aren’t in class? How can I continue to make STEM activities fun and interactive?

Whether
in an in-person, hybrid, or remote learning environment, science and STEM
teachers have likely grappled with one or more of these questions as they start
this school year amid COVID-19. And, while there certainly is not going to be a
‘right’ or ‘wrong’ way to teach science going forward, the following
considerations and tips will help deliver a safe and engaging STEM learning
experience this coming school year and beyond.
Take
all safety precautions. All teachers – especially science teachers – know that
safety comes first when educating students, even more so now with COVID-19. As
such, strictly following the established protocols from the Centers for Disease
Control and Prevention (CDC) and guidance documents from local State
Departments of Education and local school districts will be of the utmost
importance.
For
those teachers providing any type of in-person instruction, traditional
protocols for science labs will understandably need to be adjusted. This will
include new practices for physical distancing, minimizing exposure, and
enacting extra vigilance when it comes to disinfection and sanitation. For the
latter, for example, high-touch science equipment, such as microscopes,
balances, glassware, and lab instruments, will need to be sanitized before and
after each use. PPE, such as goggles, should also be cleaned appropriately
after use with an approved liquid disinfectant solution and/or UV sterilizer.
Educators should discourage the sharing of items and
equipment that are difficult to clean or disinfect and, if possible, ensure
there is an adequate amount of supplies available to minimize the sharing of
high-touch materials. The sharing of electronic devices, books, and other games
or learning aids should also be discouraged.
Teachers should develop a rigorous schedule for this
increased, routine cleaning and disinfection and build in extra time during
science and STEM classes to accommodate for these extra steps as part of the
lab activity procedure. Cleaning products should also not be used near
students, and staff should ensure that there is adequate ventilation when using
these disinfectant products to prevent students or themselves from inhaling any
potentially toxic fumes.
Provide real data. Since in-person lab experiences will be limited – or,
in some cases, not an option – it is important for teachers to find ways to
keep students engaged in the learning process. Providing students with real
data to analyze is one way to do this.
If students can’t physically collect their own data
during lab investigations, teachers can provide them with the opportunity to
watch videos or simulations of investigations and lab techniques taking place
and then give them real lab data to analyze. This will help students engage in
scientific practices, such as making predictions based on their observations
and analysis of data, and be much more impactful than just listening to a
lecture – either in-person or remotely – about various scientific concepts.
Providing students with data also lends itself to
increased opportunities for collaboration. Students can share and discuss their
hypotheses and findings during whole class or small group discussions as they
make real-world connections. By also including prompts designed to promote
engagement with science practices, it is easier for students to make sense of a
topic or question rather than if they just hear about and recapitulate it. This
is a useful method for multiple learning modalities including blended and
remote situations. It can also be used for in-person instruction as a pre-lab
activity to focus students on the observation and data gathering process when
performing these investigations themselves.
Make learning opportunities
accessible. Especially if students are learning
remotely, it is important that they can easily participate in the scientific
discovery process. Try incorporating common household items into investigations,
as well as have students take advantage of the natural world as much as
possible. This could include having students participate in hands-on, outdoor
learning opportunities where they explore soil, leaves, or other items easily
found in or around their homes.
