Charging By Conduction
 
02:01
Useful for CBSE, ICSE, NCERT & International Students Grade 07 Subject: Physics Lesson : Current Electricity Topic: Charging By Conduction During charging by conduction, both objects acquire the same type of charge. If a negative object is used to charge a neutral object, then both objects become charged negatively. In order for the neutral sphere to become negative, it must gain electrons from the negatively charged rod. 3.

Electrostatic Induction
 
08:37
072 - Electrostatic Induction In this video Paul Andersen explains how the charge distribution can be affected my electric forces produced by a charged object. In an insulator charges are fixed but in conductors the charges can move. Induction occurs when the charges in an object influence charges in another object. An electroscope can be used to observe induction and conduction. Do you speak another language?

Lesson 17 - Thermometric Properties and Processes - Demonstrations in Physics
 
14:34
Demonstrations in Physics was an educational science series produced in Australia by ABC Television in 1969. The series was hosted by American scientist Julius Sumner Miller, who demonstrated experiments involving various disciplines in the world of physics. The series was also released in the United States under the title Science Demonstrations. This program was a series of 45 15 (or so) minute shows on various topics in physics, organized into 3 units: Mechanics, Heat and Temperature/Toys, and Waves and Sound/Electricity and Magnetism.

Lesson 5.3.2 - Methods of Heat Transfer
 
04:50
Lesson 2, explores the methods by which heat can transfer between different objects or substances. We will be observing and comparing the three methods of heat transfer: conduction, convection, and radiation. Conduction is the transfer of thermal energy between two objects that are in contact with one another. In the case of convection, thermal energy is transferred by a current of gas or liquid. In the final method, radiation, thermal energy transfers through space by electromagnetic waves. In each of these cases, heat will always transfer from the warmer object to a cooler object. Eventually the warm object will become cooler and the cool object will become warmer until their temperatures are balanced. We call this point of balance thermal equilibrium. Over the course of this lesson, students will also be choosing one of the three methods of heat transfer to demonstrate to the class.

From the Science4Us K-2nd grade Physical Science module: http://www.science4us.com/elementary-physical-science/energy/heat-energy/ Generate excitement in your classroom, at Club Sizzle! Here are some facts about heat energy: #1 - Heat energy is energy that you can feel, and it can be measured by a thermometer. #2 - Heat energy is used for many things, like cooking and keeping you warm. #3 - Heat energy can be manmade or natural, but the most important sources of heat energy is the sun! #4 - Heat energy moves from hot to cold until everything is the same temperature. #5 - Heat energy can move or transfer from hot to cold in two ways: 1. conduction, when heat moves between two objects in contact 2. radiation, when heat moves in waves between objects that are not in contact and #6 - Conductors like metal transfer heat quickly, while insulators like plastic, wood and cloth slow the movement of heat from hot to cold. Science4Us is a complete, web-based K-2 science curriculum that teaches science using a fun, interactive approach. In addition to digital games and online activities, there are tons of offline experiments and hands-on projects. Parents have access to detailed lesson plans, automated student reports and session guides to help you prepare and plan. http://www.Science4Us.com Next video: Heat Energy - Conduction and Radiation https://www.youtube.com/watch?v=U_aFOpZQWs4

Transport of Water and Salts in Plants - Science
 
03:52
Transport of Water and Salts in Plants The cells present in the soil dissolve in the water resulting in a salt solution when the soil is watered. The amount of water provided to the soil is quite large; the solution will be dilute salt solution. Roots of plants have some hair like structures called Root hairs originating from cells of single layer epidermis. Dissolved salts are present in the cytoplasm of these cells, also called as CellSap. Cell sap is much concentrated than the salt solution present in the soil. Cell sap is also a salt solution. However it is much concentrated than the salt solution present in the soil. Cell membrane of the root hair is a semi permeable membrane and it separates the cell sap which is the concentrated salt solution from the salt solution in the soil which is the dilute salt solution. Water flows along with solutes from the soil into the cell sap in the root hairs. Thus roots absorb water and salts from the process of osmosis. The absorbed water and the salts move to the next cell once again by Osmosis. The movement of the water from roots to the parts of the plant above the ground is called ASCENT OF SAP. Water is transported from the roots to the leaves through Xylem vessels. Water and salts from the root hairs pass into the epidermal cells then to the cortical cells then to Endodermis cells and finally into Xylem. The transport of water from roots to the leaves is aided by the physical and chemical properties of water and the composition of the walls of the Xylem vessels. These vessels are made of lignin and cellulose which have strong, attraction for water molecules. A thin continuous layer of water Is formed in the walls of xylem vessels. This is because of strong attraction (or) adhesive force between water molecules. Between water molecules there is a strong attraction (or) cohesive force due to formation of hydrogen bond between water molecules. Because of this thousands and thousands of water molecules attach to the water molecules present on the walls. Thus forming a continues column of water molecules. The water molecules already present in the water column either get displaced or moved by the newly entering water molecules, ultimately pushing water towards the leaves. Root Pressure is the pressure exerted by the water molecules absorbed by the root hairs.
