A learning activity for the Scoop on Soils book in the Elementary GLOBE Series. Students will make predictions about what they think they will find in a sample of soil. They will investigate the sample and sort out the various items they find. Next they will spend time outside observing one or more sites to see what they find in the soil. After recording and sharing their observations they will create their own stories about the things they found in the soil. The purpose of the activity is to learn about natural things commonly found in soil and how these things impact how the soil looks and feels as well as to introduce students to the concept of decomposition. After completing this activity, students will know about various things found in soil including rocks, critters, roots, and other organic material. They will also understand that animals and microorganisms aid in the decomposition process that contributes organic materials to soils.

Using a color chart, students will make observations outside during each of the four seasons. During each session, they will try to find as many colors as possible and record what they see. As a class, they will make charts describing the colors they find in each season. At the end of the school year, students will compare their results and generate conclusions about variations in colors in nature both within a season and between different seasons. The purpose of this activity is to provide the opportunity for students to make observations in nature and compare their results, to help students understand seasonal changes as they relate to colors in their environment, and to engage students in active observation and recording skills. After completing this activity, students will understand how colors in nature relate to their local environment and to seasonal changes within that environment. Students will practice observation and recording skills, make comprehensive comparisons, and will form a hypothesis based on the information they have assembled throughout the school year.

A learning activity for the "Do You Know That Clouds Have Names?" book in the Elementary GLOBE series. Students will explore the difference between the three types of contrails, make observations of contrails outside, and record their observations. Fifteen minutes later they will make follow-up observations to see how the contrails they observed have changed. The purpose of the activity is to help students identify contrails and learn to distinguish between the three types of contrails and to understand that contrails are human-made and some contrails become clouds in the sky. Students will be able to (1) identify the three types of contrails; (2) understand that contrails are created by jet airplanes; and (3) understand that some contrails become clouds.

Students will be introduced to different species of macroinvertebrates. They will hypothesize why each insect looks the way it does. Then students will make observations of macroinvertebrates. in an aquarium in their classroom. For an optional extension, teachers can take students to a local stream or pond to conduct field observations. The purpose of this activity is to introduce students to hydrology and the study of macroinvertebrates. and to understand how macroinvertebrates. help scientists understand water quality. After completing this activity, students will have an understanding of what macroinvertebrates. are and why scientists study them.
A learning activity for the Scoop on Soils book in the Elementary …
A learning activity for the Scoop on Soils book in the Elementary GLOBE Series. Each student will explore three activities that promote understanding of and respect for soil. They will generate responses to the following questions: "What makes up soil?" and "What lives in the soil?" Next the students will watch a demonstration of how much soil there is on Earth that is available for human use. Last they will create their own soil connection sentences. The purpose of this activity is to introduce students to the importance of soil and why it needs to be studied, to help students understand how much soil is available on Earth for human use, and to help students understand the connection between soil and how it is used by living things. After completing this activity, students will understand the importance of soil science, comprehend the relative amounts of usable soil that exists on Earth, and learn the function of soil as it pertains to animals, plants and humans.
A learning activity for the "All About Earth: Our World on Stage" …
A learning activity for the "All About Earth: Our World on Stage" book in the Elementary GLOBE series. One of the "big ideas" in Earth system science is the notion of interaction among parts of the Earth system. In the Elementary GLOBE book All About Earth: Our World on Stage, the children in Ms. Patel's class discuss instances of how the four major spheres of Earth's system interact. They symbolize these interactions by using large arrows to link the system components: air, water, soil, living things and the Sun. In this activity, students continue to explore the idea of interaction among Earth components as they identify processes in the Earth system and indicate how they illustrate an interaction between two of the Earth system components. The purpose of the activity is to help students deepen their understanding of interconnections among Earth's systems, help students to identify processes where Earth's systems are interacting, and to provide practice in the observation and recording of natural phenomena. After completing this activity, students will understand that Earth system interactions are all around them, going on all the time, and that Earth's processes are interconnected. They will learn how to make observations and identify the interactions they illustrate.

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:
"All living things need phosphorus to survive. However, its low availability in soil is often a limiting factor for plant and microbial growth. Microorganisms in the plant root-soil interface (rhizosphere) can convert non-labile phosphorus into bioavailable forms. One way microbes do this is the mineralization of organic phosphorus compounds like phytate. Rising atmospheric CO₂ levels may accelerate mineralization, but the molecular mechanisms are not yet understood. Recent research confirmed that elevated CO₂ (eCO₂) increased the mineralization of phytate in the rhizosphere of wheat. Tracing the carbon flow showed that plants grown under eCO₂ increased the release of bioavailable carbon belowground, which corresponded to increased microbial growth and altered community composition. The bacterial community under eCO₂ favored groups of bacteria capable of degrading aromatic phosphorus compounds and the mycorrhizal fungi benefited from the increased supply of phosphorus and carbon..."

There are various hormones that influence the structure of the skin. These influences may be made apparent by the repeated long-term administration of various glucocorticoids or their analogues. Endogenous imbalances are generally seen in adult mature animals although congenital forms have been seen, especially with hypothyroidism. The hormones implicated as important for maintaining skin structure are thyroxine, cortisol and estradiol. Deficiencies or excessive production may result from abberations in the function of the hypothalamic-adrenal axis, the adrenal gland, thyroid gland or the gonads.
