Time dilation experiment

The second test tube was exactly the same as the first, the only difference being that the SPM was this time set to 35oC. After all the absorbencies for the varying temperatures had been recorded — the product concentration of each test tube solution was calculated using the absorbency readings at 10 minutes for each respective test tube mixture. We started the treatments at and ended at , giving the plants an hour to fully respond to their environments. After the hour ended we retrieved our plants and weighed them using the same scale, ensuring accurate measurements.

We subtracted the final weights from the initial weights, getting the change of weight in milliliters or the milliliters of water transpired. Next, to find out the total leaf surface area for each plant, we cut off the leaves of our bean plants and then traced them onto a piece of paper. We did this by finding our heart beat in our heart beat in our neck using our index and our middle finger. After we did this we set up our stepping stool which was twenty-three centimeters. Before starting we set the timer to zero. After we finished we recorded our time every fifteen seconds until our heart beat was back to resting.

Then, we calculated our BMI manually. The average egg size ranges from — um in diameters. Because of the short longevity of the sperm about 30 minutes , the sperm is obtained shortly before fertilization. It is recommended to select the best quality sperm —based on motility and number- via microscopic examination using Sedwegick and Neubauer chambers. Fertilization is carried out by adding one ml of sperm solution with approx. We repeated these steps until we got to the meter mark, which took us eleven quadrats total. We also measured how far away from the shore it was at each quadrat.

We took the elevation every ten meters. One person held the fiberglass staff and another person stood ten meters away and held the measuring pole. They moved their finger up on the pole until it was even with the horizon. Twenty tablets were weighed accurately and powdered. An amount of the powder equivalent to 5 mg of amoxicillin trihydrate content of one tablet was dissolved in 60 ml of diluent.

The solution was stirred for 10 min using a magnetic stirrer and filtered into a ml volumetric flask through 0. The residue was washed 3 times with 10 ml of diluent and then the volume was completed to ml with the same solvent. This solution was diluted with diluents to gae a concentration of 0. Burette can actually transfers water more accurate compare to pipette and micropipette. The burette calibration were done using 5ml, 10ml, 15ml, 20ml and 25ml of water.

Each volume of water was repeated three times to obtain a more accurate result. When the experiment is conducted, the mass of the empty Erlenmeyer flask is taken before each trial. For the nominal water volume of 5ml, apparent mass of water for Trial 1, Trial 2 and Trial 3 are 5. This heart rate represents a very light stimulation. On the other hand, I did 1. My heart rate was moderately stimulated during this test. To start an experiment of adsorption isotherm, Cu II aqueous solution of ml with the predetermined varying initial concentration of Cu II in the range of 6.

The experiment was stopped at mins contact time for sampling. The samples of 1 ml were placed in a ml vial and diluted with 10 ml distilled water, and filtered using a syringe filter. The filtrate was placed in ml vial for the AAS analysis. Every 30 seconds count and write the amount sowbugs in each chamber from 30 seconds to five minutes. Repeat steps for two more trials on the last trial skip step 20 to accomplish an accurate. Called wash out. After 90 seconds a second washout occurs. At seconds the length of the guinea pig ileum is reset to 2cm note.

We see this all the time with the ice cubes in our drink glasses or if we accidentally leave one out on the counter. To speed up the melting process you could hold the ice cube in your hand brrr, chilly since your body is usually warmer than the room. To make it melt even faster this way, try rubbing your hands together really fast before holding the ice cube. When you rub your hands together fast, you create friction which adds more heat through an increased temperature! Another way you can generate more heat and a higher temperature is to rub the ice cube on a piece of cloth. How about placing the ice cube on a dark piece of cloth or paper and placing it in sunlight?

Dark colors retain heat from sunlight better than light colors which is why you might feel hotter wearing a dark t-shirt in the middle of a hot summer day! Finally, we know another way to melt ice quickly is with salt which we discovered in the first experiment above! Click below to get your quick and easy scientific method sheets. In this third experiment, you will investigate with how you can keep ice from melting. The challenge is to see how slowly you can keep the ice from melting by reducing the amount of heat or energy that surrounds the ice.

This can also be done individually or in small groups. Remember, if you do choose to use the small group format, make sure to allow for time for the kids to brainstorm ideas together. There are quite a few items that can be potentially used for this ice STEM challenge! Check out the recycling bin, junk drawer, garage, and more. This is also where our dollar store engineering kit comes in handy. You can use the items you have available for a budget-friendly STEM challenge.

STEP 1: Brainstorm. What are the best materials available to keep the ice from melting? STEP 2: Decide what materials or combination of materials you want to use to keep your ice cubes from melting by insulating them! Create one or more insulated containers to test your ideas. You can choose a specific amount of time for this portion of the project or split the STEM challenge up over several days. STEP 3: When all the insulated containers are finished, place an ice cube in a small zip-top plastic bag and then place it in the insulated container. Make sure to put the lids on! TIP: As a control, you will want to place a zip-top bag, with an ice cube into it, in a similar container that is not insulated. This control container is for comparison.

By creating a control, you make it possible to determine whether the materials variables you chose are responsible for the outcome! STEP 4: Place all the containers in a cool dry place away from a heat source or direct sunlight. No extra energy is needed here! STEP 5: Check your containers every 10 minutes. Notice any differences Record your o0bservationsuntil all of the ice is completely melted. Make sure you do not handle the ice or remove the ice from the container while you make your observations.

Everyone knows that when you remove ice from the freezer, it will melt over time. The air around the ice cubes is usually warmer than the ice and it causes the ice solid to change into water liquid. States of matter too! So, if you do not want the ice to melt, you need to keep the warm air heat energy away from the ice by using an insulating material. Some great insulators just for a hint are felt, newspaper, and wool. Insulation prevents the transfer of heat to the ice so the ice crystals stay icy and cold longer. Insulation is also used to keep our houses warm in the winter in cold parts of the world by keeping the cold out! Additionally, insulation can keep the heat out of a house on a hot day too! Insulation can keep up comfortable when the temperature drops and when it rises!
