Diary of scientific and technological small production

Time flies and a day has passed. I believe everyone must be deeply touched and need to keep a diary seriously. Before you write, you should consider the content and structure! The following is my carefully arranged diary of science and technology production, which is welcome for your reference and I hope it will help you.

Diary of Small-scale Production of Science and Technology 1 20xx It will be sunny on Sunday, September 9th.

This Friday, my father and I made a wind-driven electric car. We are transformed from the windmill in the science study bag.

The windmill blows up the balloon and uses the gas in the balloon to propel the car. The wind-driven electric car that my father and I made together uses a small electric fan that is rotated by electricity to propel the car. The materials used to make the wind-driven electric car are: motor, battery, battery box, two wires, four wheels, two sticks and two small wires for making the wind-driven car? These are needed, but balloons are not.

My father and I cut the foam into a concave shape, put a flat foam behind the concave shape, and then put the two foams together. When the foam is ready, put the motor in the notch, glue it with transparent glue, and then put the fan on the motor. Put the battery in the battery box and glue it on the foam with transparent glue. When this is done, assemble the car. Then put it on the finished motor and glue it on the car with transparent glue. Finally, the motor was connected to the car, and the car moved, but the car just didn't move forward or backward. So I turned off the power. When I saw it, it turned out that the electric fan was broken (a leaf of the electric fan was broken). Then I remembered a sentence, that is: failure is the mother of success. We will modify the wind electric car later.

I was very happy that day.

Diary of small technological productions 2 Today we visited some selected small technological productions. I looked around and thought it was beautiful.

In the exhibition, I tried to find the orange lamp I made, but it was useless. I'm sad, because I worked hard to do it. Well, we have to think of a better one in the future. There are many good works in the exhibition, such as pigs, towers, eggshell paintings, rice paintings, flowers, houses made by children ... All kinds of works are carefully made by children, and I think the students who won the prize will be very happy to see them.

However, in my opinion, teachers can't choose ready-made ones to exhibit, because it is cheating and should not choose to exhibit. Teachers should keep their eyes open and not be confused by beauty.

Today's visit opened my eyes: I didn't expect so many small productions! Today's visit also told me a truth: don't do anything in a small production, but do every homework carefully, so that when you get a lot of good results, you will be particularly happy.

Teacher's comment: You will gain a lot in this way. The diary wrote your real thoughts, and the teacher saw you carefully observe them. Good. Keep trying.

Diary of a small technological production 3 Today, my mother and I made a small production called slippers. It is made of green, red, pink and purple crepe paper, cardboard, pencil, rubber, double-sided tape and scissors. Here's how to make it.

The first step in making slippers is to cut the green crepe paper into six pieces and weave three pieces into a braid, thus completing two green braids. These two braids are really nice! Just like it's real. Then cut the red crepe paper into three strips and braid these three strips. Then cut two pieces of pink crepe paper, one piece of purple crepe paper, and turn two pieces of pink and one piece of purple into braids. Finally, I stepped on the cardboard and drew two footprints. Enclose the edges of the cardboard with double-sided tape, and then cut purple crepe paper to enclose the edges. At this time, I showed an impatient expression. I dropped the cardboard and found it troublesome to make a pair of slippers. Then my mother said, "Let me help you!" I carefully picked up the cardboard, glued the insole with double-sided tape, then wrapped the green braid around the sole, and then wrapped the place where the green braid didn't wrap the red braid. In addition, braid a braid as a shoelace, then make a bow with purple and pink and stick it on the shoelace. Finally, you finished.

I looked at these beautiful slippers and let me know that I can't back down when I encounter difficulties. Sticking to the end is the truth of victory.

Diary of scientific and technological small production iv. Do you know how the bear farm is made? Let me tell you something!

First, prepare hand-made materials, such as cardboard, carton paper, paper cups, pencils, rulers, erasers, scissors, transparent adhesive, double-sided adhesive, etc. Then take out some soybeans, mung beans, red beans, black rice and corn kernels from the kitchen for use.

Start doing manual work. First, I pasted green cardboard on a large flat cardboard box as the lawn of the farm, and then made a strong little house with thick cardboard box paper and pasted it on one side of the big cardboard box. Then I put a small table made of paper cups in front of the small house, and put all kinds of delicious food cut out on the small table, but I still felt a little empty, so I put two bears on both sides of the table for a long time, which was much more vivid.

With a bear and a hut, the grass is still desolate. I will stick all kinds of beans around me until the wasteland is full. Handicraft looks full of vitality. Wouldn't it be more beautiful to put something next to the house? I put a big windmill on the left side of the house and a piece of wood with branches on the right side of the house as a small tree.

Finally, I took a look at this small handicraft and named it "Bear Farm".

Look, my craft is good!

Today, I discussed with my classmates, and no one prepared an item. Take it out and see who is more advanced.

In order to win this "advanced" award, I ran everywhere, and the libraries in the southeast and northwest were abandoned by me. Finally, Huang Tian got what he wanted, and finally let me find a book about making things. The book doesn't contain everything, including airplanes, cars, photo frames and cards.

I picked a simple and beautiful thing-a card. Although he is just a small card. His implication is profound, so I chose him.

Its production steps are very simple, only three steps, that is, painting. Stop. Insist.

First of all, I picked a beautiful cardboard and drew some pictures on it that I personally like. These pictures are all cut from the hollow part of the hollow pattern, and then the pattern can be formed. At this time, I am happy in my new life. Then the next step is to stick red floral cloth on the back of the card, but this kind of cloth is available, but what can we stick? Finally, the double-sided adhesive tape was dispatched to successfully pass this level.

I compare my products with others. Everyone gave me a thumbs-up and praised me for having a pair of "skillful hands".
