A number of experiments in this book, although totally safe if properly impetus for the production of the present Science Experiments for Everyone. Request PDF on ResearchGate | On Jan 4, , Prakash Parajuli and others published A Textbook of Practical Science for Grade PDF | In this 21st–century, students are expected to have current competencies in which one of them is science process skills. The aim of this.
Place the eggs in the pan, pointed side up. Space them so that each egg will support one corner of the board. Place the board on top of the eggs. Ask your students to predict how many books they think can be stacked on the board before the eggs crack.
It's probably more than they think! Then, place the books on the board, one at a time. Continue adding them until at least one of the eggs cracks. Record your observations, and draw conclusions.
Because chickens and most other birds sit on their eggs to keep them warm, the eggs must support the weight of the chicken without breaking. Materials: Newspaper, piece of cardboard, scissors, ruler, gr. In the center of that square, cut a small rectangle measuring 2.
Line up the cardboard hole with the slit in the yogurt cup, and use double-sided tape to adhere the cardboard directly to the foil. Gently squeeze the yogurt cup.
Observe the results. Concepts at work: plate tectonics Observations and Conclusions: Students will see that the yogurt rises up through the slit and pushes the wafers apart. Do their shapes play a role?
Materials: Three square bandannas, 11 pieces of string each 30 cm. Fold a second bandanna shown in yellow in half diagonally so that it becomes a triangle.
Leave the third bandanna shown in blue open. Take the knotted bandanna and tie a piece of string to each corner. Knot the loose ends of the strings together.

Clip a clothespin over the knotted string. Next, repeat this procedure with the other two bandannas. Raise each bandanna about shoulder height from the floor. Drop each one, and time its fall. Record the results, noting both the time each bandanna takes to fall and its flight path.
Based on observations, have students summarize how the shape of each parachute affects the way it falls. Concepts at work: forces and motion, drag and free fall, gravity Observations and Conclusions: Students will find that the knotted bandana falls the fastest and the open one falls the slowest.
They can conclude that the parachute with the maximum surface area to catch air the third one that is open creates the most drag to slow the fall. Earth Science: Which Way is North? Materials: Plastic bowl, water, sewing needle, bar magnet, paper clip, 2.
Magnetize the sewing needle by holding it by its eye end and rubbing the magnet along the needle from its eye to its point about times. Lay the magnetized needle flat on the piece of Styrofoam, and tape it in place.
Next, place the Styrofoam, needle side up, on the surface of the water. Show students which way is north in the room; observe which end of the needle points north. On another night, go out at 7 oclock or at 10 oclock and match the star map with the sky.
What happens: At 7 oclock you have to turn the chart one month clockwise to match the sky. At 10 oclock you have to turn it a halfmonth counterclockwise. The North Star remains at approximately the same place in the skyfar, far away, but directly above the North Pole.
This is because the Earths axis points to it throughout the year. All the other stars and constellations, however, seem to wander around the North Star once a day, moving counterclockwise. As the Earth rotates, it looks as if the entire sky is rotating, although the stars do not change position relative to each other. Since one turn of the Earth takes only 23 hours and 56 minutes, a star seems to rise and set about four minutes earlier than the day before.
There are 88 constellations. We still use many of these names in Latin and in the English translation. And we still use the stars as a calendar and a direction nder.
The equator is the only place from which all 88 constellations can be seen during the course of a year. In other latitudes, you can see perhaps 60 at different times, and about 24 at any one time. In the United States, Canada, the United Kingdom, and Europe, you can see the constellation of Leo, the Lion, with the bright star Regulus high up in the sky in the middle of April at about 9 p.
In August, as it gets dark, high in the southeast section of the sky you will see three bright stars the Summer Triangle. In the evening skies of October, just below the W-shaped constellation Cassiopeia, you will nd four bright stars arranged in a square making up the body of an upside-down horse with wings, the constellation Pegasus, the ying horse. You can see it in the evening skies of Miami and the Florida Keys in May and June, but its four stars are always visible below the equator.

Next, repeat this procedure with the other two bandannas. Clipping is a handy way to collect important slides you want to go back to later.
