Purpose
The demonstration set is intended for conducting demonstration experiments on mechanical phenomena.
Areas of knowledge and application
The kit provides the opportunity to complete all stages of scientific research:
— Demonstrate the qualitative patterns of the observed mechanical phenomenon (faster – slower, growing-decreasing-independent)
— Conduct quantitative research with measurement of quantities
— Form observation tables
— Construct a graph and compare the obtained experimental data with graphs of different functions
— Conduct data processing using the linearization method
What will the child learn?
The demonstration set allows you to perform 28 demonstration experiments on the following topics:
— Kinematics and dynamics of translational motion
— Laws of conservation of momentum and mechanical energy
— Mechanical vibrations
- Statics
— Conducting computer simulation of body motion
Updates
Allows you to teach the main stages of conducting experimental research, and also allows you to conduct joint research with students.
- Mechanical bench
— Assembled weight set 100 grams
— Platform with a launcher and sensors
— Trolley (2 pieces)
— Fixed block
— A block for studying motion in the presence of friction
— Special equipment for conducting experiments
— Methodological support in Russian
— Software for conducting demonstration experiments
— Software for conducting computational modeling
— Storage system
The entire set (except for the mechanical bench) is equipped with a plastic storage system, which is closed with a transparent plastic lid on latches to ensure observation of the contents. The storage system is equipped with a tray to ensure reliable fixation and storage of all elements of the set.
The mechanical bench has separate packaging.
Methodological support
The set contains a methodological guide in Russian for performing 28 experiments. The methodological guide is divided into sections reflecting different topics of the mechanics course in the school curriculum.
The description of the experiments is accompanied by a photograph of the setup and screenshots of the software, showing what results the teacher will obtain during the demonstration.
Software for conducting demonstration experiments
The software of the kit contains scenarios of demonstration experiments, including optimal launch parameters, signal recording time from optoelectric sensors, and the possibility of processing the received signal.
The software contains scenarios of experiments divided into topics and sections. Each of the scenarios includes optimal settings of the sensors used to conduct the experiment.
Software for conducting computational modeling
The calculation model of the simulation software provides the calculation of the trajectory of motion of a material point on a plane for given equations of motion in projections onto the coordinate axes and given initial conditions.
The calculation model allows us to consider 3 types of movements:
— Uniform rectilinear motion using the example of a boat crossing a river
— Curvilinear motion in a gravitational field using the example of a body thrown at an angle to the horizon
— Addition of oscillations with the same and different frequencies
