The purpose of this resource is to classify and count the reproductive phenological phases of receptacles on selected seaweed species. Students will classify and count the reproductive phases of seaweed plants within a 1-meter x 1-meter plot in the inter-tidal zone. Full description.

The purpose of this resource is to recognize patterns of green-up at the plant, landscape and regional scales. This activity is to prepare students to recognize what a bud looks like and the progression of green-up from the time of budburst. Students will arrange plant growth pictures taken from the bud, shrub canopy, grass clump, landscape and regional perspectives. Full description.

The purpose of this resource is to develop an understanding of the relationship between budburst and the environment and to help students recognize actual budburst when they are doing the Green-Up protocol. Students will do simple explorations to observe the relationship between budburst and temperature. This is a winter or dry season activity to be done prior to green-up observations. Full description.

The purpose of this resource is to increase students' awareness of the qualitative changes in plants during green-up and green-down from which they will be collecting quantitative leaf change data, and to develop an understanding of the patterns and differences among plants at the same location. Students will observe, compare, and classify plants during green-up or green-down and then make inferences ... Full description.

The purpose of this resource is to develop an understanding of plants' response to light. Students will do simple investigations to observe plant responses to light. Full description.

The purpose of this resource is to explore what pigments exist in leaves and their importance. Students will conduct an experiment using paper chromatography to separate pigments present in leaves. 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 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 ... Full description.

The purpose of this resource is to have students use GLOBE data and graphing tools to compare the influence of latitude, elevation, and geography on seasonal patterns. Students analyze the graph of the past year's maximum and minimum temperatures at their site. They compare this graph to similar graphs for two other sites and list which factors that might cause the patterns to be different and investigate ... Full description.

The purpose of this resource is to have students use GLOBE visualizations to display student data on maps and to learn about seasonal changes in regional and global temperature patterns. Students learn how sunlight spreads over the Earth at different times of the year, emphasizing the solstices and the equinoxes. Students investigate the effect of the Earth.s tilt on the spread of sunlight by modeling ... Full description.
