environments, that occur when one area is warm and another area is cool. (e.g. inversions - room natural ventilations, land and sea breezes). 37.4 Build and use simple devices to measure ambient temperature, wind speed, wind direction and rainfall and use a barometer to measure atmospheric pressure. (e.g., make and use a rain gauge; create a weather vane to determine wind direction, use a classroom barometer and record changes - a drop in pressure indicates an increased chance of rain, a rise in pressure indicates an increased chance of clear skies) 37.5 Recognize common types of clouds and relate them to different weather patterns. 37.6 Determine possible changes to the local weather by observing the amount of cloud cover, the type and color of clouds, the movement of clouds, changing wind direction and speed, air moisture, and other measured data. 37.7 Make their own weather forecast by using their observation skills to record weather measurements over a period of time and analyzing trends in the weather. 37.8 Explain how weather systems such as tropical depressions, tropical storms and hurricanes are generated and how their impacts affect humans, animals and plants. (i.e., different surfaces on earth retain and release heat at different rates) 37.9 Track a hurricane over time and connect this to the hurricane warning system for Belize. (i.e., use latitude and longitude on a hurricane tracking chart to track the movement and forecast of hurricanes) 37.10 Identify how various human actions contribute to systems to seas and ocean basins carrying sediments and nutrients with it as it empties from one water system to another. (e.g., dissolved solids and stream-borne sediments wash into rivers and then intermix with seawater; surface water drains into the underground water table; connect to the water cycle 38.3 Describe how the interconnections (38.2) between water systems are critical contributors for the distribution and productivity of aquatic animals and plants. (e.g., river and ocean currents can affect food and nutrients available for sea life; water acidity limits coral growth; poor water quality or the presence of particular chemicals limits survival of sensitive populations; the oxygen content of water determines what can live in it.). 38.4 Investigate select living things found in and around a body of fresh or salt water in Belize and predict what might happen to the living things if changes occur to the body of water. (e.g., investigate the distribution of a fish, a mammal, a bird, a coral, a surface plant, a water weed in and around the body of water, investigate its place in a food web, how it uses the body of water; predict the effect on the organism if the water gets too hot / dries up / is contaminated). 38.5 Explain how humans affect freshwater and saltwater systems and how humans can reduce those impacts. (e.g., use of adjacent lands, methods used to dispose of wastes, the harvesting of aquatic species, pollution).
