Adult frog
The adult frog now lives on land and has nostrils and lungs to breathe air. It also has front and hind legs to hop around on. This frog can start the life cycle over again by laying eggs and reproducing.
Acid in water
Plants and animals that live in water create some amount of acid in the water. The carbon dioxide that plants and animals release into the water makes the water acidic and unsafe for living organisms. This is why the water of captive aquatic animals and plants must be changed often.
Abundant green plants on the forest floor
Green plants make their own food by a process called photosynthesis. They also use nutrients and water from the soil to grow. Primary consumers (insects, chipmunks, mice and deer) eat green plants.
A rhinoceros
A rhinoceros is an example of an herbivore. Herbivores are animals that mostly eat producers, or plants.
A field of soil
Soil is an example of a non-living thing. Soil contains nutrients and living organisms, but the soil itself is not alive. Soil is important in plant growth because soil gives plants a place to anchor their roots and it also provides the plant with essential nutrients.
A fern plant in forest habitat
Ferns and horsetails are well-known seedless vascular plants. Different from mosses, ferns have branched spore producing structures which allows for the plant to produce many spores. The spots on the leaves of the fern contain the spores.
A dam in the middle of a river
Dams have negative impacts on the plants and animals that have adapted to the specific movement of natural rivers and streams. Dams also cause temperature changes, erosion, and movement of sediment that are deadly to many organisms.
A collection of fern plants in a California forest
Ferns are the most diverse group of seedless vascular plants. The leaves are compound and contain many little leaflets. The many leaflets contain spore spots. Ferns have a true root system, unlike the bryophytes.
Smokescreen: A Game about life Online Smokescreen is a cutting-edge game about life online. We all use Facebook, MySpace, Bebo and MSN to keep up with our mates - and we've all heard the stories about parties on Facebook being mobbed, or people getting stalked on MSN. The question is, what would you do
A Manual of Online Molecular Biology Techniques
This is a collection of tried-and-true technique descriptions used in teaching postgraduate students in the Department of Molecular & Cell Biology at UCT.
2.1 Providing careers education and guidance It is crucial for young people to have high-quality and impartial information and guidance to get the most out of their learning, to enable successful progression from one stage to another and to inform the important choices that young people make. 14–19 Education and Skills (DfES, 2005) Since the 1997 Education Act, there has been a statutory requirement for schools in England to provide CEG
What is the genome made of?
Genomes are composed of DNA, and a knowledge of the structure of DNA is essential to understand how it can function as hereditary material. DNA is remarkable, breathtakingly simple in its structure yet capable of directing all the living processes in a cell, the production of new cells and the development of a fertilized egg to an individual adult. DNA has three key properties: it is relatively stable; its structure suggests an obvious way in which the molecule can be duplicated, or replicated;
The Thin Blue Line-Forensic Scientists
This site draws on, and brings together, many scientific disciplines-identification of hairs and fibers, forensic psychology,DNA testing, photography, bloodstain pattern analysis, and computer forensics-that contribute to the integrated analysis of a crime and the physical evidence left at a crime scene.

Red Rover Robotics
This lesson will start with a brief history of robotics and explain how robots are beneficial to science and society. The lesson then will explore how robots have been used in recent space exploration efforts. The engineering design of the two Mars rovers, Spirit and Opportunity, will be used as prime examples. Finally, the maneuverability of their robotic arms and the functionality of their tools will be discussed.
A celebration and critical evaluation of the work of Mark Philp: Roundtable
Speakers from this day event join in discussion with Mark Philp himself about some of the issues raised throughout the day. This discussion is taken from 'A celebration and critical evaluation of the work of Mark Philp'. Mark Philp was our founding Head of Department (2000-2005) and Tutorial Fellow at Oriel College (1983-2013). He is now, since 2013, Professor of History at the University of Warwick. His work in the fields of political thought and political theory are notable for their interdis
Aram Khachaturian Biography 2/10
Aram Khachaturian was a Soviet Armenian composer who lived from 1903-1978. His music was influenced by Armenian Folk Music. He composed various piano works, as well as concertos for violin, cello and piano. He is probably best know for the piece Sabre Dance and the film music for Spartacus.
Waterwheel Work
Students learn the history of the waterwheel and common uses for water turbines today. They explore kinetic energy by creating their own experimental waterwheel from a two-liter plastic bottle. They investigate the transformations of energy involved in turning the blades of a hydro-turbine into work, and experiment with how weight affects the rotational rate of the waterwheel. Students also discuss and explore the characteristics of hydroelectric plants.
Falling Water
Students drop water from different heights to demonstrate the conversion of water's potential energy to kinetic energy. They see how varying the height from which water is dropped affects the splash size. They follow good experiment protocol, take measurements, calculate averages and graph results. In seeing how falling water can be used to do work, they also learn how this energy transformation figures into the engineering design and construction of hydroelectric power plants, dams and reservoi
