Students from the 2nd Primary School of Komotini conducted an experiment to determine whether various materials dissolve in water. They made predictions about sugar, salt, oil, lentils, coffee, and flour, then tested each material by adding it to water and stirring. Based on their observations, the students concluded that sugar, salt, and coffee dissolved in water, while oil, lentils, and flour did not dissolve despite flour appearing to at first.

Water cycle
The document describes a water experiment conducted as part of an e-twinning program to teach students about the water cycle. Students used a coffee pot, hotplate cooker, and glass to simulate the water cycle by boiling water which produced drops on the glass like rain and allowed students to see water's travel in the cycle as they played. The experiment was part of a program exploring and discovering the water cycle during the first week.
Sink or float to water
Students from the 2nd Primary School of Komotini conducted experiments to determine whether various materials would sink or float in water and salt water. They made predictions and recorded their assumptions on paper before performing the experiments. The materials tested included a coin, paperclip, empty plastic bottle, cork, and wood. Most of the materials sank in fresh water, except for the empty plastic bottle and cork which floated. When tested in salt water, the wood floated instead of sinking.
1st experiment with colours
This document provides instructions for an experiment using chromatography to separate marker colors. Students are instructed to draw with a water soluble marker on a coffee filter, place the filter in a cup of water, and observe as the water travels up the filter and separates the different colors in the marker. After drying, the separated colors can be seen on the filter.
Solutions
Solution and types of solution, interaction of solute and solvent, heat of solution is explained in this presentation.
Solvents solutions
This document defines solvents and solutes in solutions. The solvent is the liquid that dissolves the solute, which is the solid that dissolves. Examples are provided of common solutions where water is the solvent that dissolves various solutes like salt, sugar, aspirin, washing powder, and bath salts. Milk is also provided as a solvent that dissolves hot chocolate powder as the solute. Multiple choice questions are then asked to test understanding of identifying the solvent and solute in different solutions.
Soluble vs insoluble
This document discusses whether all solutes dissolve in solvents through a series of group activities using different materials and water. The activities show that flour and sand do not dissolve in water and form suspensions while sugar and salt do dissolve. Substances dissolve if they are soluble, meaning they are crystalline and "like" each other through properties like being polar. Non-crystalline or insoluble substances that do not dissolve spread throughout water as suspensions instead of forming a uniform solution. Proper shaking of medicine suspensions is needed to disperse undissolved drug particles evenly.
Solutions, suspensions, and colloids
If iced tea mix is stirred into water, it would form a homogeneous solution. The tea mix particles would be too small to separate out over time or be filtered from the water. Solutions like this form a single phase and do not separate into distinct parts. Mixtures can be classified as solutions, suspensions, or colloids based on the size of particles. Solutions have particles small enough to not separate or scatter light, suspensions have larger particles that settle out over time, and colloids have intermediate sized particles that do not separate but can scatter light.
Solution, Solute and Solvent Grade 7
A solution is a mixture of two or more substances, with a solvent dissolving a solute. Water is an example of a common solvent that can dissolve soluble solutes like sugar, salt, and coffee. There are two types of solutes - soluble substances that can dissolve in water, and insoluble substances that cannot dissolve in water and remain as particles, like sand, paper, oil, and rubber. Students are assigned to make a list of at least 10 soluble and 10 insoluble substances found in their house.

How to Make a Field Mandatory in Odoo 17
In Odoo, making a field required can be done through both Python code and XML views. When you set the required attribute to True in Python code, it makes the field required across all views where it's used. Conversely, when you set the required attribute in XML views, it makes the field required only in the context of that particular view.

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.
