The purpose of this resource is to observe plant green-down and report greendown data to help validate estimates of the end of the plant growing season. Students monitor the change in color of selected leaves of trees, shrubs or grasses. Full description.

The purpose of this resource is to observe plant green-up and report data that will be used by scientists to validate satellite estimates of the beginning of the plant growing season. Students monitor budburst and growth of leaves of selected trees, shrubs, or grasses. Species chosen should be native, deciduous, and dominant in your area. Full description.

The purpose of this resource is to select 15 km x 15 km Land Cover Sample Sites. Full description.

The purpose of this resource is to determine the rate at which water soaks into the ground. Students place two cans into the soil and add water to them to a depth of at least 5 cm. Students measure and record the time it takes the water level to drop a fixed 2 - 4 cm distance. Students repeat the measurement to determine how easily water moves vertically through the soil. Full description.

The purpose of this resource is to measure near-surface soil temperatures. Students measure soil temperatures at 5 cm and 10 cm depths using a soil thermometer. Students will be able to perform a soil thermometer calibration, carry out soil temperature measurements accurately and precisely and record and report soil temperature data. Students will be able to relate soil temperature measurements to ... Full description.

The purpose of this resource is to introduct details on how to use digital soil thermometers. A digital thermometer is used to measure current temperatures as well as daily minimum and maximum temperatures. One temperature probe is placed at a depth of 5 cm in the soil while another is installed at a 50 cm depth. The daily minimum and maximum temperatures are stored by the instrument for a period ... Full description.

The purpose of this resource is to measure the water content of soil based on the electrical resistance of soil moisture sensors. Students install soil moisture sensors in holes that are 10 cm, 30 cm, 60 cm, and 90 cm deep. They take daily readings of soil moisture data by connecting a meter to the sensors and using a calibration curve to determine the soil water content at each depth. Full description.

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 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 measure and classify the plant life at a Land Cover Site to help determine the MUC classification. Full description.
