I am not afraid of all obstacles, but I am afraid I surrender. You lose 60 minutes of happiness when youre angry for a minute. Busy is a kind of happiness, so that we do not have time to experience pain; running is a pleasure, let us truly feel life; fatigue is a kind of enjoyment, so that we have no time to empty. Life is like breathing, call is for a breath, suck is for a breath. High school physics classroom teaching plan day and month Topic Section 2.1: experimental research vehicle speed variation with time Class type Experimental course (2 hours) teach learn order mark Knowledge and skills 1. according to the relevant experimental equipment, design experiments and skilled operation 2. will use the learned knowledge to process the paper tape and calculate the instantaneous speed of each point 3. will use the tabular method to process the data, and reasonable guess 4., use V - t image to process data and observe the law 5. master the general method of drawing pictures and explain them in simple language Process and method 1., preliminary study, according to the experimental requirements, design experiments, to complete a certain way of inquiry 2. pairs of paper tape will approximate the instantaneous speed of each point 3. learn to guess, explore, and discover the rules of inquiry according to the experimental data 4., we should understand the role of mathematics as a tool for simplicity, and intuitively use physical images to show the laws and to verify the laws 5., through the experimental investigation process, further skilled timer application, and experience the method of solving instantaneous speed Emotion, attitude and values 1., through the design of the movement of the car, train students to actively think about the habits of the problem, and exercise their thinking of comprehensive, accurate Accuracy and lo
