The purpose of this resource is to teach students about the acidity levels of liquids and other substances around their school so they understand what pH levels tell us about the environment. Students will create mixtures of water samples, soil samples, plants and other natural materials to better understand the importance of pH levels. Full description.

The purpose of this resource is to develop an understanding of how water flows through different soils and how it is transformed when it flows through these soils. Students time the flow of water through different soils and observe the amount of water held and also the filtering ability of the soils. They will also observe the filtering ability of soils by noting the clarity of the water before and ... 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 activity is to observe the type and cover of clouds including contrails. Students observe which of ten types of clouds and how many of three types of contrails are visible and how much of the sky is covered by clouds (other than contrails) and how much is covered by contrails. Intended outcomes are that students learn how to make estimates from observations and how to categorize ... Full description.

This standards-based module uses hands-on activities and real-time data investigations to allow students in the elementary grades to investigate weather phenomena both locally as well as in other places around the world. By using hands-on activities and real-time data investigations, the students will develop a basic understanding of how weather can be described in measurable quantities, such as temperature, ...

This is a National Oceanic and Atmospheric Association (NOAA) sponsored website that includes a variety of resources for educators and students. Oil spills are defined by scientists and further explained using photographs and questions previously submitted by students and teachers. Experiments for students and teachers are categorized by grade level and information on how to obtain instructional kits ... Full description.

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.
