Welcome to the CELLS alive BioCams. In these BioCams, you will get to learn about cancer and bacteria cells. However, these are a bit different from "livecams" you might find elsewhere on the web - these repeat at daily or shorter intervals in order to convey information on biological rhythms.

This cell crossword puzzle uses vocabulary from CELLS alive! If you have trouble, use the "Search this Site" engine in the lefthand menu.

During development from stem to fully differentiated, cells in the body alternately divide (mitosis) and "appear" to be resting (interphase). This sequence of activities exhibited by cells is called the cell cycle. Watch this animation to learn more about each of the stages in the cell cycle: interphase, gap 0, gap 1, S Phase, gap 2, and M phase.

This activity includes two simple hands-on experiments and numerous analysis and discussion questions which will help students understand how the molecular composition and organization of a cell membrane result in its selective permeability. Specific topics covered include ions, polar molecules and nonpolar molecules; simple diffusion through the phospholipid bilayer; facilitated diffusion through ion channels or carrier proteins; active transport; exocytosis and endocytosis. This activity helps students meet the Next Generation Science Standards.

This overview presents key concepts that students often do not learn from standard textbook presentations and suggests a sequence of learning activities to help students understand how the parts of a cell work together to accomplish the multiple functions of a dynamic living cell. Suggested activities also reinforce student understanding of the relationships between molecules, organelles and cells, the diversity of cell structure and function, and the importance and limitations of diffusion. This overview provides links to Web resources, hands-on activities and discussion activities.

This game helps students to enjoy reviewing vocabulary related to cells, organelles, and the plasma membrane. Each card in the deck has a target vocabulary word and two related taboo words that the student may not use when giving clues so the other students in his or her small group can guess the target word. Many students have trouble learning the substantial new vocabulary required for biology, and this game lets students have fun while reinforcing their understanding of key terms.

Cellular respiration is the process by which our bodies convert glucose from food into energy in the form of ATP (adenosine triphosphate). Start by exploring the ATP molecule in 3D, then use molecular models to take a step-by-step tour of the chemical reactants and products in the complex biological processes of glycolysis, the Krebs cycle, the Electron Transport Chain, and ATP synthesis. Follow atoms as they rearrange and become parts of other molecules and witness the production of high-energy ATP molecules.

This overview of energy, cellular respiration and photosynthesis summarizes important concepts and common misconceptions. It also suggests a sequence of learning activities to overcome misconceptions, develop student understanding of important concepts, and relate these concepts to familiar topics such as breathing, food, body weight, and plant growth.

Students are presented with a graph of atmospheric becomes CO² values from Mauna Loa Observatory, and are asked to explore the data by creating a trend line using the linear equation, and then use the equation to predict future becomes CO² levels. Students are asked to describe qualitatively what they have determined mathematically, and suggest reasons for the patterns they observe in the data. A clue to the reason for the data patterning can be deduced by students by following up this activity with the resource, Seasonal Vegetation Changes. The data graph and a student worksheet is included with this activity. This is an activity from Space Update, a collection of resources and activities provided to teach about Earth and space. Summary background information, data and images supporting the activity are available on the Earth Update data site.

Students run a simplified computer model to explore how climate conditions can affect caribou, the most abundant grazing animal in the Arctic.

This animation illustrates how the hardiness zones for plants have changed between 1990 and 2006 based data from 5,000 National Climatic Data Center cooperative stations across the continental United States.

This video looks at the impact of changing climate on animal habitats around the world, showing how different creatures are responding to changing temperatures and precipitation patterns.

This video addresses the impact of climate change on several butterfly populations. Warming temperatures lead to shifts in location of populations of butterflies or die-offs of populations unable to adapt to changing conditions or shift to new locations.

This video provides a comprehensive introduction to the role of coral reefs, the physiology of corals, and the impacts of ocean warming and acidification on coral survival. It highlights experts from the Bermuda Institute of Ocean Sciences and the University of Miami.

This video illustrates conditions under which two infectious diseases - cholera and dengue fever - flourish, and how climate change is likely to exacerbate those conditions. Note: you may need to scroll down the Changing Planet video page to get to this video.

This video addresses acidification of the ocean and the ecological and economic implications of the resulting pH change on marine life. It includes information about how ocean acidification resulting from increased absorption of CO2 from the atmosphere is affecting ocean species such as sea urchins and oysters. Scientists from the University of California at Santa Barbara discuss their experiments with sea creatures in acidic sea water. There is an associated lesson plan and classroom activity that has students test the effects of CO2 on water pH.

Students will use books, encyclopedias, magazines, and the Internet to discover certain facts about an insect of their choice.

This infograph gives you the detailed information on classification of chromatographic methods. Chromatographic methods had 3 main types that is based on stationary, stationary phase format & mobile phase.

This video documents the effects of increasing global temperatures on biodiversity (changes in distribution, range, and numbers) and human populations. Adaptations to climate change are also outlined.
