It is that time of year again – when young scientists come together to present their science projects at the Ottawa Regional Science Fair. On March 31st and April 1st, 2017, students from grades 7 to 12 from the Ottawa-Gatineau region presented science projects attempting to answer a number of questions. Is it possible to buffer ocean acidification with baking soda? Can cilantro remove lead from contaminate water? Can invasive plants be used to absorb oil in a marina?

Since 1961, this volunteer-run event has encouraged students to design, develop, and present research projects in science and engineering. The students with the best projects are then invited to participate in a Canada-Wide Science Fair. This year, the Ottawa Regional Science Fair was held at Carleton University’s “Raven’s Nest.”

Every year, the OFNC presents awards to the creators of two or three outstanding projects that “demonstrate a knowledge of some aspect of natural history, field ecology, or wildlife conservation.” I have judged these projects with Kathy Conlan, a research scientist at the Canadian Museum of Nature, for the past three years.

Students nominate themselves for the award, and this year there were 16 entries. It was wonderful to see so many projects tackling environmental issues!

This year’s OFNC award winners were Daniel Anderson, for his invention to provide housing for pollinators ranging from bees to beetles and lacewings (“La demeure des pollinisateurs”); Julianne Jeger, for her project examining which type of road salt had the least impact on plants (“L’impact du sel de route sur les fleurs sauvages”); and Ryland Ferrall, for his project demonstrating the effectiveness of the polyphenols in tea for slowing the spread of oil during an oil spill (“The Polyphenol Effect”). Each project was awarded a $100 prize. Congratulations to Daniel, Julianne, and Ryland for their exceptional projects!

What is the most endangered bird species in the world? What is the best way to contain an oil spill? Will the emerald ash borer begin attacking lilacs once ash trees have died out? These questions and many more were tackled by students on April 8 and 9 this year at the annual Ottawa Regional Science Fair. Since 1961, this volunteer-run event has encouraged students from grades 7 to 12 in the Ottawa-Carleton region to design, develop, and present research projects in science and engineering. The students with the best projects are then invited to participate in a Canada-Wide Science Fair. This year, the Ottawa Regional Science Fair was held at Carleton University’s “Raven’s Nest.”

Every year, the OFNC presents awards to the creators of two or three outstanding projects that “demonstrate a knowledge of some aspect of natural history, field ecology, or wildlife conservation.” This year, I judged the projects with Kathy Conlan, a research scientist and the section head of zoology at the Canadian Museum of Nature. Students self-nominate themselves for the award, and this year there were 17 entries. In a world where interest in nature seems to be losing ground to technology, it was wonderful to see so many entries for this award!

Winners of OFNC awards this year were Dexter McIlroy, for his project demonstrating the effects of acid on mollusc shells (“L’acidification des océans’’ or “Ocean Acidification’’); Daniel Anderson, for his invention to prevent wildlife from being struck by tractors during haying season (“La chair de poule” or “Goosebumps”), and Maizie Solomon and Tara Hanson-Wright, for their project demonstrating the role of earthworms in soil decomposition (“Nature’s Gold Mine”). Each project was awarded a $100 prize. Congratulations to Dexter, Daniel, Maizie, and Tara for their exceptional projects!

From creating bioplastics using potatoes to developing a concentration method for trace elements in water samples, the Ottawa Regional Science Fair is full of surprises! Since 1961, this volunteer-run event has encouraged students from grades 7 to 12 in the Ottawa-Carleton region to design, develop, and present research projects in science and engineering. The students with the best projects are then invited to participate in a Canada-Wide Science Fair. This year, the Ottawa Regional Science Fair was held on March 27 and 28 at Carleton University’s “Field House.”

Every year, the OFNC presents awards to two or three creators of outstanding projects that “demonstrate a knowledge of some aspect of natural history, field ecology, or wildlife conservation.” This year, the projects were judged by me and Kathy Conlan, a research scientist and the section head of zoology at the Canadian Museum of Nature.

The OFNC special awards went to Shamus McCoy of Immaculata High School, for his project on the indicator species of Passamaquoddy Bay (below),

and to Allan Leveille of the St-Laurent Academy Elementary and Junior High, for his project entitled “How does Climate Change Affect our Macoun Marsh?” (below).

Each student received a $150 prize. Congratulations to both Allan and Shamus for their exceptional projects!

Ottawa Regional Science Fair: and the awards go to…

by Natalie Sopinka

This year the Ottawa Regional Science Fair was held April 4-5 at Carleton University. With over 200 students from grades 7-12, the event was filled with young bright minds asking questions about energy, the environment, human health, and natural resources.

Kathleen Conlan and Natalie Sopinka were on hand to judge projects that demonstrated “knowledge of some aspect of natural history, field ecology, or wildlife conservation.” From brachiopods and ducks to mushrooms as oil absorbents and wort plants in motor oil, the breadth of topics was vast and the talent abundant. The Ottawa Field-Naturalists’ Club presented awards this year to Emma Kirke, Aidan Gurung, and Shamus McCoy.

Emma Kirke – Survival of the Narrowest

A trip to Hawaii and a windstorm in Washington sparked Emma’s interest in trees. She was surprised to hear from a relative that Hurricane Iniki had drastically changed the beautiful landscape she saw during her visit to Kauai, and that her friend’s family had to evacuate their house in D.C. after severe winds felled a tree on it causing a gas leak.

Emma investigated how tree crown shape affects wind resistance. Focusing on tree shapes found in the Ottawa area, Emma made model trees from different materials (e.g., straw, yarn, felt) to mimic how trees bend and move. She then constructed her own wind tunnel and measured how long each model tree took to fall when blasted with different wind speeds. Emma found that trees with oval-shaped crowns, such as the Silver Maple (Acer saccharinum), were the most wind resistant. Knowing Ottawa is no stranger to harsh, icy winters, Emma also mentioned that the conical shape of the Norway Spruce (Picea abies) would be most resistant to collapse under glaze ice.

Emma also received the Ottawa Horticultural Society’s award.


Aidan Gurung – Saving Swainson’s Hawks

Aidan enjoys birding with her aunt at the family cottage. When she read a study on populations of Swainson’s hawks (Buteo swainsoni) declining in their South American wintering grounds due to pesticide use, she wanted to make sure further declines weren’t going to happen at breeding and stopover sites in North America. Using satellite tags attached to Swainson’s hawks, the U.S. Geological Society has tracked the migration path of over 30 individuals. As the birds move, their geographic location is sent from the tag to satellites that record the coordinates.

Aidan accessed this data (available online) and followed the migration of two hawks. She noted throughout their migration how long each hawk spent in areas with lakes, farms, highways, forests, and houses. Aidan then made recommendations as to which areas should be protected to ensure that habitat used frequently by Swainson’s hawks is not disturbed.


Shamus McCoy – Looking into the Past

Shamus collects fossils in the Ottawa region and knows a thing or two about the Ordovician-Silurian extinction event, when nearly all marine invertebrates disappeared. Shamus studied local fossil records to gather evidence to support the current hypothesized cause of the Ordovician-Silurian extinction, glaciation. He first observed changes in species abundance between fossil layers; for example, filter-feeding brachiopods disappeared in the extinction but detritus-feeding ostracods did not. He also detected iron pyrite in post-extinction strata: this suggests that an earlier environmental event reduced oxygen levels in oceans, as the mineral only forms under conditions of low oxygen.

Shamus hypothesized that mountain formation during the Ordovician-Silurian (known as Taconic orogeny, see below) led to a volcanic event that released aerosols into the atmosphere resulting in acid rain, which altered oxygen levels in the oceans. When the mountain building stopped, Shamus proposed that extensive erosion (not ideal for filter-feeders) could have sequestered carbon dioxide from the atmosphere, lowering temperatures and causing glaciation.

Shamus also received the Natural Resources Canada – Earth Sciences award. Stay tuned for a guest post on the blog by Shamus!
