The Global Learning and Observations to Benefit the Environment (GLOBE) Program is an international science and education program that provides students and the public worldwide with the opportunity to participate in data collection and the scientific process, and contribute meaningfully to our understanding of the Earth system and global environment.
GLOBE provides grade level-appropriate, interdisciplinary activities and investigations about the atmosphere, biosphere, hydrosphere, and soil/pedosphere, which have been developed by the scientific community and validated by teachers. GLOBE connects students, teachers, scientists, and citizens from different parts of the world to conduct real, hands-on science about their local environment and to put this in a global perspective.
Students make predictions about the properties of various soil samples and examine several types of soils, recording their observations.
After reading and/or listening to the Elementary GLOBE book The Scoop On Soils and completing this activity, students will know about soil’s different properties including texture, colour, and size.
Students will create experimental conditions in terrariums to study what plants need to live. These variables include presence or absence of soil, water, and sunlight. Students will record growth of radish plants as well as observations of the water cycle in their terrariums. At the conclusion of their experiments, students will compare their results and analyse how water, Earth materials, air and sunlight are all necessary to support living things.
Each day for a week, students will observe the colour, visibility, and conditions of the sky during the day and again at sunset. During each observation, students will complete either a Daytime Sky Report or a Sunset Sky Report, recording sky conditions and drawing what they observe. At the end of the week, students will compare their observations and discuss the differences between observed colours depending on time of day and sky conditions.
