What Repair Proteins are Expressed in C-Ferns After Exposure to Varying Amounts of UV Radiation?

Scientists need to have mastered algebraic slope-intercept concepts in order for this lesson to be effective. They will measure and graph solar panel output as a function of the amount of radiation striking it, discovering that there is...

There is the same amount of water on earth now as there was when it was formed. The water from your faucet could contain molecules that dinosaurs drank! Young scientists build their own hydrologic cycle model and observe...

The biogeochemical cycle ... no physics? The fourth installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program introduces the biogeochemical cycle by having pupils simulate movement between Earth's...

Young biologists define reproduction vocabulary terms, answer critical-thinking questions, label a diagram of the human life cycle, and complete a chart comparing mitosis to meiosis. This is a well-balanced worksheet. Even though it...

AP environmental science or college-level ecology classes will glean a tremendous amount of information on nutrient cycles from this detailed PowerPoint. It covers nutrient requirements, biogeochemcial cycles, decomposition rates, and...

Humans can have a big impact on the environment, specifically the influence they have on the carbon cycle. First, the class will define and discuss each of the earths four major spheres, the biosphere, hydrosphere, atmosphere, and...

Diagrams with annotations are shown on each of these eighteen slides, which summarize the processes of respiration. The focus is on the 3-step oxidation process and the Krebs cycle.  Students should be able to follow these slides...

Water that leaves the oceans must eventually return. The animations in the final lesson of the four-part NASA series show the complex path water can take across landforms before returning to the ocean. Approximately one-third of the...

How does water vapor move from point A to point B? The second installment in a series of four on the water cycle allows scholars to analyze satellite images to answer this question. The satellite animations show how evaporation and...

Knowing about the hydrologic cycle is the first step to understanding the carbon cycle. Upper graders discuss the earth's water content, polar ice caps, and the concept of the ecological cycle as it applies to carbon, nitrogen, and other...
