The environment: living and non-living things
Competency Relationships Between Organisms and the Environment. Abiotic versus biotic Matter can alternate between the abiotic and biotic environment in cycles. . HISD Project REACH U.S. Department of Education. Additional. In all these environments, organisms interact and use available resources, such Explore the relationships between ideas about organisms and their Science related interactive learning objects can be found on the FUSE. In this module, students will investigate the environment around them with a focus on the needs of living things and the effects of changes in the environment on these organisms. Students will synthesize their learning during the module to publish a newsletter for the local community kinenbicounter.infoB Understand the relationship.
Chapter 5: The Living Environment
Recent functional magnetic resonance imaging studies, for example, have demonstrated the heritability of task-related brain region activation and shown how a functional mutation in an important gene is associated with differences in the function of the prefrontal cortex, where executive skills reside Egan et al. Epigenetics Among the most compelling, emergent stories in developmental biology is the discovery of the molecular, epigenetic processes by which environmental conditions can regulate the activation or deactivation of genes.
It is increasingly understood that development is driven not only by the joint, additive, or interactive effects of genetic and contextual variation but also by the direct regulation of gene expression by environmental events and experiences see, e. Research in epigenetics has shown that experiences can alter gene expression through their effects on molecular regulators that interact with the DNA molecule.

These early modifications create a kind of genetic tabula rasa for the epigenetic reprogramming of cellular diversity Boyce and Kobor, Only by such divergent activation of genes could so many tissue types emerge from a single, common genome and ensure the stability of each cell type over generations of cell division.
Differential gene expression also guides the differentiation of cellular functions, for example, the development of neurons into unique subsets, the guidance of axon growth, and the spatial organization of brain development Fox et al.
At the same time, epigenetic processes also are called upon for adaptive, dynamic responses later in development, such as those a child makes to changing environmental conditions like exposures to severe adversity and stress.
This epigenetic modification of a regulatory region in the glucocorticoid receptor gene increases its expression, thereby blunting cortisol reactivity. Paradoxical though they may be, the uses and functions of epigenetic processes play critically important roles in the successful emergence of social, educational, and biological capacities. A permanent change in the ecosystem could cause an organism to become an endangered species. Human needs and the environment The environment is impacted by humans.
When human needs impact the environment, the result can be beneficial or detrimental.
Humans use parts of other organisms for food and clothing. Some animals are used as pets for humans for enjoyment or protection. Animals can be used for asistance when compensating for disabilities and to perform work or provide recreation. Humans can control and alter the environment.
Farming by humans increases the amount of food by encouraging plants to grow by cultivation. Humans can also control the environment to compensate for disabilities. Humans can permanently damage the environment. According to this theoretical perspective, moral reasoning is related to the development and coordination of the three different but decisive domains of knowledge regarding normative reasoning: These authors conclude that the use of this kind of reasoning by young children suggest that they have to handle some basic knowledge about the distinction between living and nonliving things.
Furthermore, it is worth noting that these ideas contrast with the well-documented fact concerning the limited knowledge that young children display about plant life and, also, the difficulties that they find when it comes to attributing life status to plants Gatt et al. It has even been suggested that there is a progressive development of the animacy concept according to which the concept of life is granted firstly to human, then to animals and after that, to plants Yorek et al.
Summing up, some studies report that even young children award a particular moral status to living creatures in the environment, including plants. This fact leads some scholars to suggest that children possess some basic knowledge of the notion of living being around which they can structure their biocentric justifications.The Ecosystem - Educational Video for Kids
However a significant number of studies state that the understanding of the notion of living beings, especially when it comes to considering those of which have a stationary nature, is thought to be beyond the comprehension of young children. With this in mind, the objectives proposed in this study are as follows.
Moreover, the study will attempt to determine whether young children judge harmful actions against nature more severely than the breaking of social conventions and, consequently, whether they regard undesirable behaviour against the environment to be more of an equivalent to moral transgressions.
Subsequently, the aforementioned data concerning both the comprehension of the concept of living being and environmental judgment will be examined in relation to the age of the children.
Finally the study reflects on the relationship between the understanding of the concept of living being that the children of the sample show and the pattern of choice that they express concerning the alternative between actions against the environment and violations of social conventions.
Methods Characteristics of the sample As regards the sample of this study, it is comprised of children 52 boys and 66 girls.

Of these, 35 All the children in the sample analysed were in the appropriate academic level according to their age. The subjects of the sample attended three state schools located in three different towns with more than 3, inhabitants in the region of Uribe-Coast, in the Basque province of Biscay, Spain Beck, A singular cultural feature of the Basque community is the co-existence of two official languages: Spanish which it shares with the other provinces in Spain and Basque, which is at present spoken by aroundpeople in the Basque Autonomous Community, the Regional Community of Navarre also in Spain and south western France Cenoz, Bearing in mind this characteristic, the meeting with children were mainly conducted in Basque, which is the academic language in the three schools involved in this study.
All these schools were visited in the first quarter of
