Understanding Physical and Chemical Parameters of Ocean Water Using CTD Profiles
Overview
A focus of the PolarTREC Southern Ocean Diatoms expedition was to collect water samples and physical profile data using oceanographic technology. Oceanographers rely on the real-time data transferred from the water column to the ship-based computers using a CTD sensor. The CTD measures conductivity (salinity), temperature and depth
Students will observe how soils and rocks of different densities behave in wind and in water. They will make predictions and careful observations as they learn about sediment transport and sediment rates in streams and rivers.
Students experiment with a “blubber glove” to experience how insulation affects heat transfer, and how the adaptation of blubber helps penguins as well as seals, whales and walruses survive in bitterly cold waters.
The Solar Oven Science activity was developed as a way to target conservation of energy. Some students understand that he sun can be used for heating and cooking but they mistakenly think that this can only work in deserts. Because of conservation of energy solar cooking and heating can work in temperate and even arctic environments. The linked
Students will conduct quantitative and qualitative observations on living organisms. By recording careful measurements, making and testing various hypotheses, on super mealworms, students will gain some understanding of how wildlife researchers conduct their studies.
Objective
Students learn to take measurements on living organisms and use those measurements to consider the health of the organisms.
Dividing the class into Little auks and predators, students complete survival game for several seasons. After tallying up total volume of food collected, survival rates of the chicks can be graphed and analyzed.
Objective
Students will be able to experience the hazards that Little auks must avoid in order to survive. Students will understand the value of
