TITLE: Wad a Watershed Lab INTRODUCTION: Using models is very important in science. In this lab‚ you will design a model that will help you investigate the relationship between land surfaces and water on Earth. OBJECTIVE: To design a model that will help you visualize watershed characteristics. PROBLEM: How can we use the relationships between land surfaces and water to understand conservation of resources and pollution? HYPOTHESIS: In your own words‚ write a hypothesis about how the relationships

The Carbon Cycle is a complex series of processes through which all of the carbon atoms in existence rotate. The same carbon atoms in your body today have been used in countless other molecules since time began. The wood burned just a few decades ago could have produced carbon dioxide which through photosynthesis became part of a plant. When you eat that plant‚ the same carbon from the wood which was burnt can become part of you. The carbon cycle is the great natural recycler of carbon atoms. Unfortunately

The layers of Earth How do scientists know what is in the center of the earth? How can we know what the core of the earth is made of‚ if scientists have never studied any materials from a depth below 7.5 miles? Earth is approximately 4.6 billion years old‚ and over this time period‚ many things have changed inside and out. The formation of our planet is quite amazing. Earth consists of multiple layers. The three most distinct or main layers are the core‚ mantle and crust. The inner portion is

The planet Earth is emphasized as “the rare Earth” in numerous literatures because of its unique physical conditions and the complicated interactions among all biotic and abiotic systems. Isotope dating indicates the earth was formed approximately from 4.53 to 4.568 Ga‚ according to isotope

Food Chain: A sequence that links species by their feeding relationships. Herbivores: Organisms that only eat plants. Carnivores: Organisms that only eat animals. Omnivores: Organisms that eat both plants and animals. Detritivores: Organisms that eat detritus‚ or dead organic matter. Specialist: A consumer that primary eats one specific organism. Generalist: Consumer that has varying diet. Trophic levels: The levels of nourishment in a food chain. Food Web: Shows the network of feeding relationships
