Thesis (M.B.A.)--Boston Universit

Freshwater Macroinvertebrates

The purpose of this resource is to sample, identify, and count macroinvertebrates at a Hydrology Site. Students collect, sort, identify, and count macroinvertebrates from habitats at their site. Educational levels: Middle school, High school, Intermediate elementary, Primary elementary

Phenological Gardens Protocol

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. Educational levels: Primary elementary, Intermediate elementary, Middle school, High school

Modeling the Reasons for Seasonal Change

The purpose of this resource is to understand what causes the Earth's seasons with a focus on the Earth's tilt and spherical shape. 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 different tilts using a three-dimensional polyhedron which they construct from paper. Students calculate the relative sunlight intensity received by the Northern and Southern Hemispheres to understand seasonal differences between the hemispheres. Educational levels: Middle school, High school

Cloud Protocols

This PDF document discusses a field activity for K-12 students. The purpose of the activity is to observe type and cover of clouds including contrails. Students will observe ten types of clouds and how many of three types of contrails are visible, how much of the sky is covered with clouds, and how much is covered by contrails. The PDF is an instructor guide with detailed advice for administering the activity and data sheets. Educational levels: High school, Intermediate elementary, Middle school, Primary elementary, Undergraduate lower division

Davis Weather Station Protocol

This resource provides instructions on how to log atmosphere data using a Davis weather station. A weather station is setup to measure and record atmospheric measurements at 15-minute intervals and can be transferred to the GLOBE program via email. Students can view data for their school that are continuous and show variations within a day. The data collected includes wind speed and direction and pressure thereby supporting a more complete study of meteorology using GLOBE. Students pursue a more extensive set of research investigations. Educational levels: Middle school, High school

Investigating Leaf Pigments

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. Educational levels: Middle school, High school

Calculating Relative Air Mass

The purpose of this activity is to introduce students to the concept of relative air mass and demonstrate how solar elevation angle affects the intensity of sunlight that reaches an observer on the ground. Students work in teams to calculate air mass using simple geometry. Teacher background materials are included. Educational levels: Middle school, High school

Relative and Absolute Directions

The purpose of this resource is to learn about latitude and longitude while developing math skills. Students begin by asking the simple question: 'Where Am I?' Then they learn about the magnetic Earth and the use of compasses and angles. Students also learn about the difference between relative and absolute locations. Throughout this activity, students practice using a variety of math skills. Educational levels: Primary elementary, Intermediate elementary, Middle school, High school

Arctic Bird Migration Monitoring Protocol

The purpose of this resource is to observe when selected bird species first arrive at your study site, and to count the numbers until few or none of these birds are seen. Students select a common and easily identifiable bird species in their region and observe when the bird species first arrives. Students use binoculars or telescopes to scan a study site and count how many they see. They continue to observe every other day until few or none of the selected species can be seen. Educational levels: Primary elementary, Intermediate elementary, Middle school, High school
