Objectives:
1.Enjoy participating in science activities and experiencing the fun of playing with parachutes.
2.Using the method of observation and comparison, explore the relationship between the speed of parachute landing and the weight of the hanging object, and boldly express your findings and record the results in complete language.
3.Improve observation and hands-on skills.
Event Preparation:
A number of self-made parachutes, a number of weight clips, a number of tick mark markers, and a number of markersEvent Highlights:
Enjoy participating in science activities and experiencing the fun of playing with parachutes.
Difficulty:
Using the method of observation and comparison, the relationship between the speed of parachute landing and the weight of the hanging object was explored.
Activity process:
a) Conversation import.
Observe"Parachute", Stimulate children's interest in participating in activitiesTeacher: Children have seen all kinds of umbrellas, (lesson plan from: Teacher Qu Lesson Plan Network) Today, the teacher also brought a strange umbrella, see what it is?(Show parachute**) What does a parachute look like?The big round one is called the umbrella surface, and the umbrella surface is square and long, and there are umbrella ropes underneath. Do you know when to use a parachute?What else can a parachute be used for?Teacher: Do you like to play with parachutes?
Teacher: Today, Mr. Hong has also prepared a simple parachute for everyone, so let's have fun together.
2) The first attempt to play with a parachute guides children to perceive, explore, and fall objects through manipulation.
1.Ask your toddler to take a parachute and gently throw it up to see what happens to them.
2.We played with the parachute just now, no matter how high it was thrown, it always had to fall, (from Mr. Qu's lesson plan) What did you find?How did it fall?
c) Second Exploration"Parachute"。
Guide children to perceive the relationship between the speed of parachute landing and the weight of the hanging object) 1.The teacher introduces the experimental operation materials and guides the children to make conjectures.
Teacher: The big clip baby is so happy to see the little clip playing and wants to come and play, let's invite it to play togetherWhat do you think of the big clamp coming down in a parachute?Will it be the same as a parachute with a small clip?Which one will be faster (guide children to guess, what is the difference between the parachute speed of the large clamp and the parachute of the small clip) The teacher has a ** here, please take a look at it, think about which kind of parachute is faster?(Big clips, small clips) draw the one you think will fall faster in it and give the slower parachute an X.
Make a summary based on the children's conjectures. Guide children to do hands-on experiments.
2.Describe the experimental and observation requirements.
1) Find yourself a safe place to experiment.
2) Use the right method to compare.
3) According to the results of the comparison, give the faster parachute and the slower parachute x.
3.Children are autonomous**, and teachers guide them.
4.Combine the record sheet to sort out the summary.
1) Encourage children to express the experimental process and results boldly.
Teacher: Who will tell me what you have discovered?
2) Guide children to discuss: Why do some parachutes fall faster and some parachutes fall slowly?
3) The teacher combs the summary.
Teacher: The parachute with a small clip is light and falls slowly, while the parachute with a large clip is heavy and the parachute falls quickly. (This lesson plan contains supporting PPT courseware).
