Science Fair Projects Kids Will Think is Fun – Does Air Take Up Space

Magrietha Du Plessis asked:

Do you want your kids to love science? If so, make sure they do science fair projects kids will find fun. Kids will not be interested in projects that are not very visual and that are not very easy to do. They want to see the results in a very short time; I’ve seen that over and over again with my little granddaughter Anabel. She loses interest very soon if things are moving too slow!

So, here is a science fair projects kids will find fun and easy. It actually is two experiments that can be done, first the one and on the next day the other so it does not take too long.

Does air take up space?

The case of the dry tissue paper

After you have done this experiment you should be able to answer the following questions:

1. How does the tissue paper feel after the first part of the experiment?

2. What do you see when you turn the glass slightly?

3. What causes these bubbles?

4. What happens to the tissue paper now?

5. What do you think stopped the tissue paper from getting whet the first time?

6. What was there between the tissue paper and the water?

7. Look around, is there air around you?

Can you see the air?

What you need for your project:

* One tissue

* A glass

* A bowl

* Water

How to do this experiment:

1. First you have to crumple the tissue and place it in the bottom of the glass making sure there is a relatively big space between the rim of the glass and the tissue.

2. Now you have to turn the glass up side down and submerge it in the water making sure you keep it completely vertical.

3. Take the glass out of the water and feel the tissue.

4. Now do the same, but turn the glass slightly so the air can escape.

5. Take it out again and feel the tissue.

6. Now and try all the questions on top.

Conclusion:

Air takes up space and it is all around us. The tissue stays dry in the first part because the air between the water and the tissue prevent the water from reaching it and making it whet. In the second part you allowed the air to escape and water could fill that space left by the escaping air. The air was not there to form a layer between the water and the tissue any more, so the water reached the tissue and made it whet.

The case of the airlock

After you have completed this, one of our science fair projects kids will love to do, you should be able to answer the following questions:

1. What do you do when you seal the opening of the bottle with the adhesive clay?

2. What happens when you pour the water in the funnel while the bottle is sealed?

3. Why do you think it happens?

4. Why doesn’t the air escape through the opening in the funnel?

5. Why do you keep the top opening of the straw closed at first?

6. What happens when you take away your finger after you have inserted the straw in the opening of the funnel?

7. Why do you think it happens?

8. What does it tell you about the properties of the water as well as the air?

What you need for this experiment:

* A funnel with a short stem

* A bottle with an opening that the funnel fist snuggly in

* Adhesive clay

* A straw

* A jug

* Water

What to do:

1. Place the funnel in the bottle

2. Seal the rim of the bottle with adhesive clay making sure it is completely sealed and no air can escape

3. Put the water in a jug and pour some of it into your funnel and observe what happens.

4. Now you take the straw and while keeping one end closed with your finger, push it into the funnel.

5. Remove your finger

6. Observe what happens now

Conclusion:

The air in the bottle is trapped and prevents the water from running into the bottle. No air can escape through the water as the water molecules in the opening of the funnel because of the surface tension in the water. (What is this?) When you insert the straw in the bottle, you hold one opening closed to prevent the water from the funnel to go into the straw. When the straw is through the water layer and you remove your finger, the air in the bottle can escape through the straw and the water starts pouring into the bottle.

These two science fair projects kids will love to do can be turned into a very good science fair project. Pay attention to the scientific method and your display.

Drum Hardware for a Complete Drum Set

Victor Epand asked:

A drum set is like a well-built house with foundation and framework. This framework includes drum pedals, stands, toms, lugs, hoops, tension rods, and drum racks. And the foundations are the drum shells. All these together make up the drum hardware of the drum. Just like a house cannot be built without foundation and pillars, the drum is incomplete without the hardware because it acts as the pillar of the drum. Each of the hardware has different role to play.

Drum hardware basically refers to various kinds of stands that hold up the drum and the cymbals. Let us start with the most important pieces that play a vital role in building up the drum set as well as drum sound.

The pieces of metal that are attached to the side of the drum are the lugs. The main aim of the lugs is to attach the drum hoops or rim, which is fixed with the help of tension rods. Hoops mainly hold the drumhead in place and even help in tuning the drum.

Coming to the drum shells, it refers to the material used in the drum. Like, beginner’s kits are made up of basswood or mahogany but higher kits are made up of more costly woods to get better sound quality.

Adding next piece of the drum hardware, i.e. the pedals. They are available in different types like, single chain drive, dual chain, belt driven, single spring pedal, dual spring pedal and pedal with footboards. Among them the dual chain pedals are harder and can take heavy foot. Even pedals with dual spring are much better than the single one. The footboard pedals are the high-end pedals and are strongest. Therefore, a combination of dual chain, dual spring and footboard makes a tough pedal.

Next important parts of the drum hardware are the stands. Stands give support to the whole set to provide proper positioning to it. The types includes:

– Boom stand: The most longest of the other hardware, the boom stand provides easy positioning to the cymbals anywhere around the kits.

– Cymbal stand: This drum hardware not only supports the cymbals but also hold toms, cowbells and tambourines as well.

– Hi-Hat stand: This is one of the vital parts of the hardware. It is like a straight cymbal stand that has a spring-operated pedal connected to a rod that opens and closes the top hi-hat cymbal. This cymbal is linked with the clutch that has a hole in the middle where the rod fits and is protected in the open position by a *****. The drummer needs to place both the feet on the pedal, while using hi-hats in the closed position, and just hit the lever and the hats drop. And has to do vice-versa to reset it to the open position.

– Snare stand: A snare is played most of the time and so it is necessary to have a solid snare stand. It is better to use double braced snare stand rather than using single braced that are light weighted and move often.

Another important part of the drum hardware is the toms. They are greater than the stands by 14” and have legs to stand on their own. Once the drum is assembled it is mounted on the toms. It should be mentioned here that the sound quality of the drum depends on its positioning on the toms.

Virginia Tech Hokies Tickets – Big Men Don’t Cry

Gen Wright asked:

Virginia Tech made a disappointing start to its Atlantic Coast Conference season. The Hokies lost to Duke, 69-44, in their first ACC encounter of the season.

Duke, the No. 5 in the nation defeated Virginia Tech comprehensively with a margin of 25 points, at Durham, N.C.

The Blue Devil’s Cameron Indoor Stadium was full of rowdy fans and amidst such a hostile environment the Hokies had eighteen defensive rebounds, six blocks and seven steals. Their shooting was affected by the environment, and they only shot 36 percent from the field, with a slight better accuracy at the free throw line. The Hokies shot 58 percent from the free throw line.

The Blue Devils(12-1, 1-0 ACC) started the first half with an 11-0 run, but then Virginia Tech shot 6 points with 8:30 minutes to go in the first half and came back in the game. At the end of the first half the Hokies were trailing the Devils by 8 points.

Second half belonged completely to the Devils. The Hokies managed to score only 13 points as compared to the 31 scored by the Devils. The shooting percentage of the Hokies plummeted to 33 percent. Within a matter of 4 minutes, the Devils extended their 11 point lead to a 20 point lead. The Dukes kept pushing and lay-up by sophomore forward J.T Thompson was the only field goal for the Hokies in the last 8:30 minutes of play.

Senior guard Malcolm Delaney missed all the three shots from behind the arch, senior forward A.D Vassallo scored 1-for-4. In all the Hokies shot 1-for-9.

However Delaney was the leading scorer for the Hokies, by scoring 12 points. Sophomore forward Jeff Allen also performed well and scored nine points and also took five rebounds, highest for the Hokies in the game. Senior forward Cheick Diakite played hard and stuck to his job of protecting the rim; he also chipped in with the scoring and scored eight points along with five rebounds and three block in twenty minutes.

Virginia Tech was out-rebounded by The Duke,38-28 in the game. Forward Kyle Singler was the leading scorer for the Blue Devils with 19 points, he also led the Duke in rebounds with eight rebounds. Gerald Henderson supported Singler well and scored fifteen points and took eight rebounds.

The Blue Devils proved to be better shooters than the Hokies and shot 95 percent from the line. They also converted 19 of the 20 foul shots they took as a result of 18 personal fouls committed by the Hokies.

Virginia Tech should not get disappointed, as they played a good game. They still lead the season with 9-5. The defeat in their first match of the ACC this season can be mended by winning the game against Virginia at their home court.
