In this activity students observe and sketch clouds, describing their forms. They initially generate descriptions of a personal nature and then move toward building a more scientific vocabulary. They then correlate their descriptions with the standard classifications using the ten cloud types identified for GLOBE. Each student develops a personal cloud booklet to be used in conjunction with the GLOBE ... Full description.

The purpose of this resource is to observe the flowering and leaf stages of selected garden plants throughout the year. After a phenological garden is planted, students observe the growth of leaves and blooming of flowers on the plants. These plants were selected because each plant blooms at a different time in the year. Full description.

The purpose of this resource is to introduce what a catchment basin is and how it works. Students will make a 3-dimensional model of a catchment basin to understand how water moves through the basin and explore how water is affected when there are changes in the basin. Full description.

The purpose of this resource is to develop a classification system for a set of objects and learn about hierarchical classification systems. Any set of objects, such as insects or rocks, may be used as well. Full description.

The purpose of this resource is to observe budburst on selected trees at a Land Cover or Phenology Site. All students will learn about hummingbird natural history and ecology. Students will learn how to identify and age male and female Ruby-throated Hummingbirds and to observe migration and feeding behavior. Students will learn how to make connections among hummingbird behavior and weather, climate, ... Full description.

The purpose of this resource is to investigate the annual cycle of plant growth and decline using visualizations and graphs. Students will analyze visualizations and graphs that show the annual cycle of plant growth and decline. Students will explore patterns of annual change for the globe and each hemisphere in several regions that have different land cover and will match graphs that show annual ... Full description.

The purpose of this resource is to characterize the physical and chemical properties for each horizon in a soil profile. Students identify the horizons of a soil profile at a soil characterization site, then measure and record the top and bottom depth for each horizon. For each horizon, students describe the structure, color, consistence, texture, and abundance of roots, rocks, and carbonates. Samples ... Full description.

The purpose of this resource is to measure the pH of a soil horizon. Students mix dried and sieved soil samples with distilled water. The mixture is allowed to settle until a relatively clear layer is formed. Students use a pH pen, pH meter, or pH paper to determine the pH of the sample. The procedure is done three times for each horizon. Full description.

The purpose of this resource is to explore soil and soil properties. Students discover the variability of soils, derive relationships among soils and the soil forming factors, and link the GLOBE Soil Investigation to the students. local environment. Students use soil samples from their homes to identify properties that characterize their soils. They compare and contrast their soils to those of their ... Full description.

The purpose of this resource is to have students develop a qualitative understanding of the characteristics and patterns of seasons and highlight the relationship of seasons to physical, biological and cultural markers. Students observe and record seasonal changes in their local study site. They establish that these phenomena follow annual cycles and conclude the activity by creating displays that ...
