All those wires are attached to different explosives which burn at different frequencies. The trick of the 20 explosions is that they push the pieces of uranium (or plutonium) together to a ball with an over-critical mass, which explodes. They have to time this extremely accurately, however. Microseconds differences will make the ball lopsided and less effective. Part of the solution is to make each and every cable the same length which is why the Gadget looks like a ball of wires.
As we did this with the water the weight of the egg went up because the water soaked into the egg and made it heavier. With the syrup it seeped into the egg and made it weigh less because the sugar in it would dry out the egg and make it weigh less. It done this because it wants equilibrium and that is where there is the same amount of water on each side of the plasma membrane, so it dried up the water to make all the water in the cup the same.
Egg floated the least in the cup of water with no salt with an average of 0 cm. Egg floated 0.3 cm in the cup of water with 15 ml of salt. The average hight egg floated was 2.15 cm. The hight of egg increased as the amount of salt in the water
Finally, when the egg was placed in corn syrup, it floated on the surface of the solution. This was because the egg floated in solutions hypertonic to its inside. This also shows how much water was transferred from the egg to the sugar solution. The higher the percentage of corn syrup was, the faster the rate of osmosis was. As a result, the egg placed in 75% corn syrup, 25% filtered water had the lightest weight (0.5 oz), while the egg placed in 25% corn syrup, 75% filtered water weighed 2 oz.
The surface that had the least amount of friction was the wood placemat. With the shipping materials the most amount of friction created was with the sandpaper and, the shipping material that created the least amount of friction was the foam. I would recommend using the clear, plastic mat for the flooring inside the cargo ship because, it prevented 450g of washers from making the boc slide or fall. The cup was able to hold all washers that were given and could’ve held more than what we had. Conclusion/discussion: Paragraph
The astronauts ' prints are a bit too clear and could’ve only been made in wet sand. ‘That 's nonsense’, said Bad Astronomy’s Plait. Moondust, or regolith, is "like a finely ground powder. When you look at it under a microscope, it almost looks like volcanic ash. So when you step on it, it can compress very easily into the shape of a
Afterwards record the volume. Extract the aluminum block from the cylinder and dispose of the remaining water and clean the cylinder before storing it away. For the second half of the experiment retrieve a single piece of aluminum foil and cut out a 15cm x 15cm square. Then calculate the width and length of the foil and record the data in the table. Finally determine the mass of the piece of aluminum foil and record it.

First, you must buy the correct type and amount of sand. This information is written on the sand filter label; the sand can be bought at any pool and spa store, and quite a few hardware stores too. You will also need some basic tools and plumbing supplies (screwdriver, hacksaw, PVC Glue, and PVC fittings, if your sand filter is like most and not equipped with unions) Here are the steps for changing the sand on your sand filter: You need to remove the top mount multiport or top cap on your sand filter. The multiport is where you change the filter settings from filter to backwash, rinse, etc. Usually the top is held on with a sand filter collar or band at the base, made of 2 crescent bends of plastic or metal, that is held in place with two large screws or bolts which you must remove.
To prepare the column for chromatographic separation, a 5.75 inch Pasteur pipette is required; plugged with glass wool (or cotton) at the bottom. The column was filled up to ½ of the height of the pipette, and then loaded with a thin layer of sand. The sample was loaded on top of the sand and loaded again with a thin layer of sand. Eluents were loaded one after the other: hexane; dichloromethane with hexane; dichloromethane; and dichloromethane with methanol. Elution was the main process used in this experiment; there are two types of elution isocratic and gradient.
Beneath Our feet Experiment 1: We put different types of rocks in to three piles that were called Igneous, Metamorphic and Sedimentary. Igneous comes from a volcano. Metamorphic is heat and pressure and Sedimentary is a mixture of conglomerate, fossils and layers. Experiment 2: We put chalk and 3 spoons of sand into a cup and shook it really hard. Some of the sand turned pink which was the colour of the chalk.
This tough shell also helps the nerites survive in the often dry and hot supralittoral zone, where a decrease from 83%RH to 75%RH was seen at Hastings Point. This adaptation is to retain moisture using a special structure – the operculum – which can be sealed when the snail is not eating to retain moisture within the shell. This is used especially between the high tides, as water only reaches this high zone at these times. Another factor associated with the supralittoral zone is harsh wind conditions, which was observed at Hastings Point where the temperature indicated a 12% increase in average temperature between the littoral and supralittoral zones. The black nerites adapted behaviourally to survive these conditions.
Before we can begin to look for our names, we need to know what type of letter does our names start with. Going around the classroom can each of you tell me the first letter of your name? Would the first letter in our names be lower case or upper case? b. Activity: Name Recognition • On paper/card board/ plastic caps write a variety of upper and lower case letters • Cut the letters out • Place both magnet letters and paper/cardboard/ plastic caps into the sand table • Mix the sand around with the letters • Have the children sort through the sand table to find the letters to their names • Use the tweezers or spoon to grab the letter in the sand • Have the students place their letters on the table • Put the letters in the correct order to spell a name 8.
In the egg drop experiment that Tatum and I conducted the egg went through various stages of force, energy, and friction. These things were occurring before the egg was about to fall, while it was falling and after it fell. Before the egg fell it was being held a couple feet above the ground and as it was waiting to fall it consisted of potential energy. When the egg was released to fall gravity pulled it down to the ground, while the egg was falling it obtained air friction and kinetic energy. The impact that the egg has when it hit the ground is also friction.
Which means when the straws hit the ground the energy will go up through the straws, and not into the egg. I put hot glue up inside the mega straws, so if some were weak the hot glue would dry and harden making the mega straws harder to break. The great thing about gas is if you have an egg around something with gas in it, the solid (the egg) will sink into the gas. Making a protective layer of gas around the solid object, so if it falls the gas will take the energy giving it back. Which is why all shipping companies us gas balloon type things, my design takes the energy up through a solid, and brings it out the end of the solid.
