| A volunteer helps a school child with DNA extraction. |
Let鈥檚 talk about the DNA makeup of an onion. Let鈥檚 talk about firing a potato from the barrel of a cannon. Let鈥檚 talk about science.
Science is a lot more than tables and equations in textbooks. It鈥檚 about people and their passions and every year at Dalhousie, graduate students set out to share their passions with school students from elementary to high school as volunteers with Let鈥檚 Talk Science.
Let's Talk Science (LTS), a national, non-profit organization, strives to improve science literacy through innovative educational programs, research and advocacy. At Dalhousie, LTS volunteers visit classrooms throughout Nova Scotia, facilitate field trips to 黑料吃瓜网labs, judge science fairs and give presentations and demonstrations throughout the community.
鈥淰olunteers gain experience disseminating scientific topics to a wide range of ages and audiences,鈥� says Stephanie Collins, Phd student in psychology and an LTS coordinator. 鈥淚t's great for those interested in improving their presentation skills, especially for teaching classes or conference presentations.鈥�
Volunteers can commit as little as an hour to as much time as they like. The level of participation is entirely up to them.
鈥淚 joined LTS because I enjoy what I do and it鈥檚 fun to communicate that to other people, especially students,鈥� says Julian Ware, masters student in mechanical engineering and an LTS volunteer. 鈥淲hen you鈥檙e excited about what you do, they are too.鈥�
Mr. Ware, who hopes to volunteer with LTS as long as he can, frequently wows students at local schools, bringing a potato cannon to launch spuds across a field. Students take over and do everything from charge the cannon to estimate flight and distance. Mr. Ware says the benefits of being involved with LTS are invaluable.
鈥淚t's really improved my public speaking and confidence,鈥� he explains. 鈥淭here's no better way to sharpen your ideas and learn to communicate effectively than by explaining them to a grade six class.鈥�
Each year, teachers request LTS volunteers to visit their classrooms and many become annual LTS clients. The added value to the students is a great learning tool for teachers to complement their lessons.
鈥淪ince funds for taking students out of the classroom are always hard to come by, this is the next best thing,鈥� says Karen Trenholm, teacher at Sackville High School and annual LTS client. 鈥淗aving someone come in who is a passionate expert in their field is a great thing for students to see.鈥�
Ms. Trenholm believes LTS peaks students' interest in science by making science fun and engaging. 鈥淚f it's relevant to their own lives they tend to be more interested.鈥� she says.聽 鈥淟TS always tries to make their presentations relevant to society.鈥�
LTS is so popular with teachers, in fact, that demand for volunteers outnumbers supply. While this may seem like a good problem, to best sustain and improve their positive reputation, LTS needs more volunteers to continue to bring their experiences to the classroom.
LTS is open to any senior undergraduate or graduate students, faculty, staff or alumni specializing in science and engineering. The 黑料吃瓜网chapter of LTS covers the costs to all volunteers. All that鈥檚 required from volunteers is their enthusiasm. Those interested in participating with LTS can contact lts@dal.ca, or visit .
