Zoo Virtual Field Trip Katherine A. Cottrell Liberty University EDUC 500 Zoo Virtual Field Trip In today’s technology age‚ virtual field trips can provide cognitive and affective gains similar to those of a real-life study trip. Field trips taken online can transport students to locations too far away to travel and are cost effective for the school district and parents as well. Teachers can guide and interact with all students in the class for the duration of the virtual field trip‚ which

Assuming they are emitted with negligible energy‚ where m is the mass of the electron‚ in this case. After emerging from the hole in the anode‚ the electrons enter a region with no electric fields‚ therefore then traveling at a constant velocity. The beam’s path is illuminated due to the ionization of the gas. A magnetic field is applied to

For the field observation‚ I went to Friends of crown heights educational center. Friend of Crown Heights is a Universal Pre-kindergarten program. This program prepares 4 year olds with language‚ literacy‚ cognitive‚ physical and social skill needed to excel in Kindergarten. The school was very welcoming. The teachers and staff were helpful and the students were friendly. In the classroom‚ I was assigned to observe there were three teachers and about 15 kids; mostly all girls. The classroom was made

Electric motors work due to electromagnetic interactions: the interaction ofcurrent (the flow of electrons) and a magnetic field. Problem Find out how to make a simple electric motor.

repel one another in a similar way and always come in pairs: every north pole is yoked to a south pole. 3. An electric current in a wire creates a circular magnetic field around the wire‚ its direction depending on that of the current. 4. A current is induced in a loop of wire when it is moved towards or away from a magnetic field‚ or a magnet is moved towards or away from it‚ the direction of current depending on that of the movement. While preparing for an evening lecture on 21 April 1820‚ Hans

Introduction The purpose of this lab is to examine the motion of an electron‚ when it encounters a constant magnetic and electric field. We will also observe when the electric field and magnetic field will cancel each other out. This will lead to the electron having no net force acting upon it. By adjusting the values for the magnetic and electric fields‚ we will be able to check the different paths the electron follows. From this data we will be able to calculate the charge-to-mass ratio. Then

RED is used to convey the meaning of warmth in communication. Instead of relying on electromagnetic waves or light waves to carry data‚ a RedTacton transmitter couples with extremely weak electric fields on the surface of the body. The weak electric fields pass through the body to a RedTacton receiver‚ where the weak electric fields affect the

Force Field Analysis Force field analysis is a management technique developed by Kurt Lewin‚ a pioneer in the field of social sciences‚ for diagnosing situations. It will be useful when looking at the variables involved in planning and implementing a change program and will undoubtedly be of use in team building projects‚when attempting to overcome resistance to change. Lewin assumes that in any situation there are both driving and restraining forces that influence any change that may occur. Driving
