The authors of this TIEE Research Paper evaluated the use of data-intensive case studies and small group discussion on students' quantitative abilities in a large environmental science lecture...
Students investigate the factors that control the rate at which CO2 is emitted from soil using simple soil chambers and soda lime in a field experiment. Students in small groups design and conduct...
A series of photographs showing the widening of a road that then caused an increase in the sediment load in the streams below the road. The photographs show the road and the surrounding tropical...
In this TIEE dataset, students address the question of how changes in demographic vital rates influence the rate of population growth. Students learn how projection matrices and elasticity...
In this exercise, students will use data concerning lifespan and demography to generate graphs, compare the survivorship curves of two cohort groups with Logrank (Mantel-Cox) tests, and explain the...
Desert star (Monoptilon bellioides) flowers in bloom. Desert star is an annual plant that grows in very arid regions of the southwestern United States. Desert star and other desert annuals may delay...
In this activity, students examine the nature of the interaction between army ants and ant-following birds. Ant-following birds benefit from the relationship by staying just ahead of the ants and...
Students use data to test hypotheses on breeding bird species richness. Students will exercise critical thinking skills to interpret data sets and maps. They will then create graphic presentations...
These Landsat images show Kenya’s Masai Mara Reserve on December 4, 1994, a year with normal rainfall, and November 27, 2009, a year when the rains failed and a severe drought overtook the land. The...
