Science mini crafts for 1st graders

Science production can cultivate children's hands-on ability, exploration ability, develop children's imagination and exercise their operation ability, the following is a few suitable for primary school students to introduce science experiments.

1 homemade shuttlecock.

Materials: 1 empty drink bottle, 2 fruit foam nets, 1 rubber band, 1 glass marb;

Production method: 1. An empty beverage bottle, minus the top half;

2. Cut to the neck of the neck with scissors, cut into 8 parts, and cut each part into the shape of petals of the same size;

3. Put the fruit foam mesh outside the bottle and fix it with a rubber band;

4. Take a foam net, wrap a glass ball, and stuff it at the mouth of the bottle, exposing about 1 cm;

5. Wrap half a table tennis ball on the mouth of the bottle, cut the four sides into whiskers, cover the mouth of the bottle and fix it with a rubber band, so as to make a badminton.

2 Microphones.

Materials: 2 paper cups, 1 thread, 1 pair of scissors;

How it works: Sound travels faster in solids than in air.

Production method: 1. Use scissors to drill a small hole at the bottom of each of the two paper cups (the size of the hole can pass through the line).

2. Tie a knot between the two ends of the thread through two small holes.

3. Mark the name, production principle, and use method on the work, and write the name and student number.

How to use: Two people, each holding a paper cup, one person puts the paper cup in the ear and closes it, and the other person speaks to the paper cup, and the sound transmission function is realized.

Precautions: 1. The thread cannot be woolen.

2. One person needs to put the paper cup on the ear tightly.

3. When using, the thread between the cups must be tightened so that the effect can come out.

3 Make a herbarium.

While conducting small experiments, it can help our children increase their understanding of various plants, which is of great significance to the expansion of children's knowledge.

Method: Sandwich the intact plant specimen between two napkins, we press the specimen with two wooden boards and place it in a dry, sunny place, otherwise the leaves may turn black. After a few days of specimens drying, we glue the specimens on the top of the paper, and finally mark them.

4 Make a tumbler.

Tumblers have always been a good memory for us when we were children, and for our elementary school students, it will leave many good memories if they can make one by themselves, and at the same time let them understand the center, the principle of gravity.

Method: Make a hole in the egg, pour out the yolk and egg white inside the egg, clean it and wipe it dry, introduce rice and glue into the egg, and wait for the glue to dry when the tumbler is completed.

The science and technology knick-knades for Year 1 are as follows:1. Material preparation: an old hard carton (such as a toy box, snack box), plasticine, latex, 2 small wooden sticks, a ruler, and a utility knife.

Observe the appearance of the box, if there is a beautiful look that can be used as a decoration. The smiling face shown below.

<>3. Cut out the scrap material to a good size to make the head cover.

4. Dig out a front windshield opening for the front hood.

5. Paste transparent plastic with glue as the front glass.

6. Paste the front cover on the body, and the body also dig out the left and right window glasses and paste transparent plastic.

7. Make four wheels out of plasticine.

8. Wear the wheels with wooden sticks and install them on the body, and the carton car is made.

Simple scientific little crafting: The cowman made a super fun little toy with a bunch of bamboo sticks.

Homemade soap paper.

Materials and tools for crafting:

Hygroscopic white paper, a small piece of soap, a brush and disposable beverage cans.

Production method: first chop the soap and put it in the jar, put the cup on the stove after filling the appropriate amount of water, wait for the soap to melt, cut the white paper into the size of a matchbox, apply the soap to the soap liquid one by one, and then take it out to dry it to become the soap paper of the socks.

Make a weight measurer · · A plank, a rubber band.

Parachute: Materials: round plastic film (diameter 15 cm), four strings (15 cm), a light umbrella pendant.

When it is done, it is lowered from the first floor and can float in the air for twenty minutes. (Have students work in groups to bring materials to the open class, pay attention to the timekeeping, and write the experiment report.) ）
