It was probably either not functioning right or had not been adjusted correctly. If another balance scale was used for the procedure maybe the data could have been more accurate. To continue, another mistake that could have lead to poor data was when pouring the unknown metals into the graduated cylinder to measure the volume, some metals had fell to the
to find the lightest bag in the 3 weighing, but the mathematician thought it could be done in less, so I need to find out the least amount of weighing it takes to find the lightest bag. Also, the king used a pan balance for all of his weighing. I started by weighing 4 bags on each side of the scale to see which side was lighter. Then from those results I thought to weigh the 4 bags that were on the lighter side by 2 and 2. After this you would find one side weighing less than another. Then you would
The Physics of Scales To the dismay of some and a necessity for others, scales can be found about everywhere in today’s society. It never fails; if you go to the doctor you will step on the scale. They are at the grocery store, in most bathrooms and even in some of our favorite stores. Were we might even pay a quarter to have a machine tell us our weight, out loud. We as a society are obsessed with our weight. You’re asked for your weight when renewing your driver’s license. Every time you get
0968 mol dm-3 So the concentration of the acid is 0.0968 mol dm-3. Evaluation: There may have been some limiting factors during the experiment which may have affected the results. The first of these may have been the scales, it is possible that when I was weighing out my Na2CO3
stirring rod, goggles, scale, filter funnel, filter paper, evaporation dish. The variable that I will be changing is the mass of Iron Filings (in grams) added to the Copper Sulphate. Plan: 1. Collect all appropriate apparatus and then set up. 2. Carefully pour 20cm³ of Copper Sulphate into a beaker. 3. Place a sheet of filter paper on to the scales and then set scales to zero. 4. Measure out 0.5g of Iron Filings on to the filter paper by reading the scales. 5. Pour the Iron
each the same length and weight in 5 different test tubes with different concentrations of sugar solution and distilled water. I will be weighing and measuring the size of the potato pieces after being in these solutions for 24 hours. Apparatus ◠5 test tubes ◠5 potato slices (each with the length of 7.5cm and weighing roughly 1.53g) ◠Scales ◠Ruler ◠Scalpel ◠50cm³ distilled water ◠50cm³ sugar solution ◠Tweezers ◠Pen & paper ◠Plate Method
top of this was a rectangular wood block weighing 0.148-kg (1.45 N/ 9.80 m/s/s). A string was attached to the wood block and then a loop was made at the end of the string so a Newton scale could be attached to determine the force. The block was placed on the Veneer and drug for about 0.6 m at a constant speed to determine the force needed to pull the block at a constant speed. The force was read off of the Newton scale, this was difficult because the scale was in motion pulling the object. To increase
find the concentration of sucrose in a potato cell. Also I can observe when a cell is totally plasmolyised. PLAN I plan to complete this experiment within an hour. Firstly, I will cut 15 potato chips, 3 each for 5 different solutions, each weighing 1.2grams, cut with a 4mm corer to approx (full word) 4cm. I will measure weight, as length is less accurate. The weight of the chip may vary as much as 0.02 g each way, which will make it a lot easier to do, but may provide me with less accurate
raisin in each beaker. One with a weak solution, one with a strong solution. - Measure the mass of the raisins every 5 minutes for 30 minutes. - Record results in a table. Equipment 2 beakers – to contain the raisins and the solutions. Scales – to measure the raisins and the sugar’s mass. Stopwatch – to measure the time taken. Tweezers – to pick up the raisins. I need to take the following safety precautions: - Don’t use fingers to pick up raisins. - Keep an eye on the beakers
it comes to do the actual experiment. Pre-test method Apparatus · Glass Beaker · Measuring cylinder · Tripod · Bunsen Burner · Stirring Rod · Thermometer · Stopwatch · Heat proof mat · For safety: Goggles · Weighing scales · Gather equipment and set up as shown below: · Choose your temperatures (I am going to perform the pre-test with the temperatures 20°C, 40°C and 60°C) · Measure 10g of sugar and 100cm³ of 20°C water · Pour the water and sugar into
feet long, sometimes weighing in at over 100 pounds. There were hundreds of fish. When we were settled on our perch, the show really began. They came in from the deep blue abyss. Slicing their way through the ocean currents, they judged us with their grayish eyes as they passed. They were testing us, as they got closer every time. The sharks would come in and out of our field of view, passing inches over our heads, as they glided through our bubbles. We could see their scales they were so close
as water from the potato diffuses into the sucrose solution. Predicted graph of results: [IMAGE] Apparatus * 6 test tubes * 6 different concentrations of sucrose solutions * Potato * Potato cutter/core * Digital measuring scales * Measuring cylinders * Knife * Test tube racks * Coloured felt pens * Tissue paper Method I will need 3 pieces of potato in each tube. As there are 6 tubes I will have to calculate how many pieces I will need altogether. I think

Equipment: * Heatproof mat * Bunsen burner * Boiling tube * Bung * Delivery tube * Water bath * Measuring cylinder (250 cm³) * Digital weighing scales * Spatula * Clamp and stand * One molar copper carbonate (1 gram) * Two molar copper carbonate (1 gram)
it so that osmosis can easily occur. Here I think more water will come into the cell than out of the cell. Equipment: Potatoes Cork Borers Distilled Water 1M Sugar Solution Beakers Measuring Cylinders Rulers Timers Scales Knife Paper Towels Method Step 1: Collect and set up equipment as shown in diagram: [IMAGE] Step 2: Cut out 5 cylinders of potato using a cork borer. Step 3: Measure and weigh the cylinders. Step 4: Pour out 50
because the experiments weren’t as accurate as they could have been. My measurements of zinc carbonate weren’t as accurate as they needed to be, to ensure a fair test. This was because it is almost impossible to weigh exact measurements on electronic scales. Another problem was there could have been moisture inside of the test tube, which could have affected the results. Even with these problems I think the results will be quite similar to the theoretical yield. I choose to change the amount
the concentration of sucrose increases, the mass of potato decreases.

Apparatus --------- · Clamp stand · Clamp · Copper calorimeter · Spirit burner · Matches · Thermometer · Ruler · Metal safety tray · Top pan balance (digital scales) · Measuring cylinder Method ------ I will need to collect all of the above apparatus and then put it together like in the diagram below. I will weigh the alcohol I will be burning and then put it under the copper calorimeter. I will use a measuring
Out of all the species walking, flying, slithering or swimming, there aren't many who have been around as long, survived as well, or come in so many shapes and kinds as the shark. The earliest evidences of sharks are isolated spines, teeth and scales that appeared about 430 million years ago in the Silurian Period, known as the "Age of Fishes". Sharks have a sleek, streamlined design which helps them swim without using up a lot of energy.They certainly need to conserve their energy because they never
we will to set up the apparatus in a way that would give us a large temperature rise in a short amount of time, e.g. 2 or 3 minutes. Here is a diagram of how we set up the apparatus. To perform this experiment we needed: * Electric weighing scales * A measuring cylinder * 5 spirit burners (1 for each fuel) * A copper calorimeter with a lid * A thermometer * A clamp * A Bunsen burner * A stop clock Method ====== The first step was to carry out some preliminary
is no lie to be found in that. One can look back on the porter's hidden truths at the beginning of the scene, Porter: "Knock, knock! Who's there, i' the other devil's name! Faith, here's an equivocator, that could swear in both the scales against either scale; who committed treason enough for God's sake, yet could not equivocate to heaven: O! come in, equivocator."
