Accurately measuring temperature and water content of the upper 5 mm of the soil surface can improve our understanding of environmental controls on biological, chemical, and physical processes. Here we describe a protocol for manufacturing, calibrating, and conducting measurements with soil surface temperature and moisture sensors.

States of Water

Water exists in any one of the three classical states: solid (ice), liquid (water), and gas (steam or water vapor). The state of water depends on i) the intermolecular forces that draw molecules together and ii) the kinetic energy that leads to movements that pull them apart. Water freezes when the intermolecular forces are greater than the kinetic energy. Unlike most other substances, water is less dense in its solid state than in its liquid state. This is because each water molecule can form...

Source: Smaa Koraym at Johns Hopkins University, MD, USA Temperature Dependent Decomposition of Hydrogen PeroxideExpand We suggest that students work in pairs for this experiment. Equipment controls may vary. In this lab, you'll perform a decomposition reaction where a single compound breaks down into two or more simpler products. You will observe the decomposition of hydrogen peroxide into water and oxygen. This decomposition happens very slowly, so you will use iron (III) nitrate as a...

Drosophila fruit flies can distinguish small changes in temperature and therefore select environments with favorable thermal conditions. This video describes a behavioral assay that tests the temperature preference of Drosophila larvae on a linear thermal gradient.
FAQs
Temperature changes the solubility of gases, including oxygen, so warmer or cooler conditions can alter the amount of dissolved oxygen available to aquatic organisms. Because oxygen availability affects biological communities, temperature measurements help researchers interpret changes in habitat quality and assess how seasonal variation or climate-driven warming may influence aquatic ecosystem health.
Changes in water temperature alter molecular motion and can modify enzyme function, which in turn influences the rate of biological reactions. These effects can change metabolic activity in aquatic organisms and microorganisms. Measuring temperature alongside biological responses helps researchers connect environmental conditions with differences in growth, activity, development, or other physiological processes.
Aquatic organisms may respond to changing conditions through acclimation, behavior, or physiological adjustment. These responses can influence how organisms tolerate seasonal temperature variation and how they remain active within their habitats. Studying those adjustments helps explain why environmental warming or local habitat changes may affect species distribution and the composition of biological communities.
Water temperature is an important condition to track when studying photosynthesis because it affects biological activity and enzyme function. Researchers can compare photosynthetic responses under different temperatures to examine how thermal variation influences aquatic biological processes. This approach helps connect physical environmental change with the functioning of aquatic organisms and communities.
Researchers measure water temperature as an environmental variable and control it when experimental comparisons require consistent thermal conditions. They can then relate temperature differences to outcomes such as microbial growth, photosynthesis, development, or dissolved oxygen availability. Recording these conditions makes it possible to distinguish temperature-related effects from broader changes in aquatic systems.
Monitoring is useful when researchers investigate seasonal variation, habitat change, or climate-driven warming. Temperature data provide context for interpreting shifts in dissolved oxygen, species distribution, and biological community health. The measurements also support studies of microbial growth and organismal development, allowing biological observations to be evaluated alongside changing environmental conditions.
Temperature data can help researchers evaluate microbial growth, photosynthesis, development, species distribution, and the health of aquatic communities. Interpreting these outcomes together is valuable because temperature can affect chemical conditions, gas availability, and biological activity at the same time. This makes thermal records useful for linking environmental change with ecosystem dynamics.
