How we see things
Light reflects off objects and enters the eye, where it is focused on the retina. An image is formed on the retina and nerve signals are sent to the brain through the optic nerve. The brain then identifies the object based on the signals received from the retina.
WAYS OF MAKING ELECTRICITY year 6
Power stations produce electricity by burning fossil fuels like coal, oil, and natural gas. However, relying heavily on these resources is unsustainable because supplies are dwindling and their combustion contributes to global warming. Other power sources like nuclear energy produce radioactive waste, while solar and wind power are currently very expensive options. The document examines various methods for power generation and their advantages and disadvantages from an environmental perspective.
REFRACTION year 6
As light passes between transparent materials like air and water, it changes speed and bends at the boundary between the materials. This phenomenon is called refraction. When light travels from a faster medium like air to a slower one like water, it bends toward the normal line. To observe refraction, submerge objects like pencils or straws in a glass of water and see how they appear bent through the glass.
The eye pdf
The document describes the main parts of the eye and their functions. It includes a diagram labeling the iris, pupil, cornea, optic nerve, retina, and lens. The cornea protects the eye, the iris controls the pupil to regulate light, the lens focuses light, the retina detects light and sends messages to the brain via the optic nerve.
CLASSIFICATION OF MATERIALS year 6
The document classifies materials based on how much light they transmit. Transparent materials, like foil and cellophane, allow a lot of light to pass through so you can see clearly. Translucent materials, like cling film and trace paper, permit some light to pass through but not enough to see through clearly. Opaque materials, such as tissue paper, paper, cork, wood, and plastic, do not allow any light to pass through and block light.
REFLECTION year 6
This document discusses light reflection and how it works with different surfaces. Shiny, smooth objects scatter light in many directions when a torch is shone on them. Mirrors are flat, smooth surfaces that reflect light in a single direction and reverse images by flipping left to right. The document provides links to experiments where light is bounced off a mirror and reflected from front to back.

HOW SEEDS ARE DISPERSED
The document discusses several methods of seed dispersal used by different plant species. It notes that strawberry, dandelion, burdock, sycamore and poppy seeds are dispersed by wind or animals which eat and transport the seeds, while acorns are carried by animals. Effective seed dispersal is important for plant reproduction and survival.
GERMINATION
Germination is the process by which a seed begins to grow, where the root and shoot emerge from the seed to form a new plant. Seeds have different parts like the seed coat and hilum. After germination occurs, the radicle root emerges first followed by the splitting of the seed coat and expansion of the cotyledons which provide food for the new seedling. For germination to take place, seeds need proper conditions like water, oxygen, and the right temperature, and some seeds also require specific light levels.
PARTS OF THE FLOWER
The document describes the main parts of a flower, including petals, sepals, nectaries, carpel, stamens, and receptacle. Petals attract insects and protect other parts. Sepals protect the flower bud. Nectaries in the center produce nectar to energize insects. The carpel is the female part containing ovules. Stamens are the male parts that produce pollen. The receptacle attaches all flower parts.
PARTS OF A PLANT year 5 and year 6
The plant kingdom is divided into flowering and non-flowering plants. Non-flowering plants do not produce seeds, while flowering plants produce flowers and seeds. Flowering plants have leaves that produce food through photosynthesis, stems that transport water and support leaves, and roots that take up water from the soil.
PLANTS (Year 5)
The document describes several experiments with plants, where some plants were given light and water, others only light or only water, or neither. The plants that were given both light and water thrived, while those without either light or water did not survive, and those with only one or the other needed the missing element.
How power gets to our homes (group B)
Electricity is generated at power stations and sent through transformers to increase the voltage for transmission along power lines. The electricity then passes through substations where transformers decrease the voltage before being distributed to homes through wooden poles, with further reductions in voltage to safely deliver power for use.
How power gets to our homes (group A)
Electricity is generated at power stations and sent through power lines at high voltages of 400,000 volts for long distances. Transformers at substations reduce the voltage to 11,000 volts before it travels to local neighborhoods. The voltage is then further reduced and carried through wooden poles and cables to buildings like homes, schools, and shops where it can be used.
Curved mirrors Year 6
A simple explanation about the differences between concave and convex mirrors with some exemples of each one.
PRETTY RITTY
Doggo, Donko, and Cocko each ask Pretty Ritty to marry them but she refuses when they sing for her. Catto also asks Pretty Ritty to marry him and she accepts after liking his singing, but then he tries to eat her since she is a rat.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UP
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems
9
Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.
