How does water temperature affect the amount of dissolved oxygen? Ⅰ. Introduction Dissolved oxygen is just one of the many ways to measure water quality. It means the volume of oxygen that is contained in water. The amount of dissolved oxygen in water usually determines the quantity of organisms living in that water. Dissolved oxygen levels vary by how much oxygen the water can hold‚ how much oxygen is produced by photosynthesis‚ and how much oxygen is consumed by respiration. If water is too warm

2 Angles make a difference Aim The aim of this experiment is to test whether the angle of sunlight affects the surface temperature on earth. Hypothesis I believe Block B will receive more sunlight than Block A‚ because the lamp shines directly onto Block B. Materials * * Lamp * 2 thermometers * 2 blocks of wood * Black plastic tape Procedure 1. Cut out two small identically sized pieces of black tape and attach onto wooden blocks so that they make pockets. 2.

After performing this experiment‚ it was found that the surface the chocolate was placed on could make a major difference. The hypothesis that was made had mostly incorrect predictions‚ but with some correct ones. It was found that using the palm of one’s hand was the best surface on which to melt chocolate‚ as was predicted. It melted so far‚ and so fast‚ that the experiment had to be altered. Coming in second place was the surface of black paper‚ something that was not expected. The black

diagram above.) 2.Secondly I will measure the required amount of Zinc (Zn) on a weighing scale‚ again for precise accuracy. I will then measure the starting temperature using a thermometer. Next I will pour the Zinc into the test tube containing CuSO4. 3.Finally I will measure the final temperature using a thermometer and record the temperature rise in °c. (I will carry out all my experiments under lab safety precautions.) Variables *I will vary the mass of Zinc‚ & use the following Zinc weights:

The earth doesn’t have an even balance of heat and the reason for this is because the earth is a geoid ‚ the sun’s rays hit directly on the equator(caused by unequal insolation due to three factors: angle of strike‚ atmospheric depletion and surface area.) and then move outwards towards the polar areas. The atmosphere together with the ocean currents work hard to try and even out the imbalance of heat energy by redistributing the air from the equator to the Polar Regions but also from the Earth’s

1.The average temperature contrast between winter and summer is greater for continental polar air than for maritime tropical air. Explain why. Maritime tropical air is very warm and humid because its source regions are tropical and subtropical seas. This air mass retains these properties year-round and is responsible for oppressive summer heat and humidity east of the Rocky Mountains. Dry continental polar air develops over the northern interior of North America. In winter‚ continental polar air

conducted to determine the optimal temperature for bacterial and fungal Amylases and evaluate how temperature affects the catabolic rate of enzymes. Enzyme reaction rate was measured using an Iodine test in which drops of starch solution with either fungal or bacterial Amylase exposed to different temperatures were mixed with Iodine. Iodine is a dark blue color in the presence of starch and turns light yellow in its absence. Bacterial Amylase had an optimal temperature of 55°C‚ meaning that starch was

How Does Temperature affect the Ability to Bounce of a Ping-Pong ball? Physics Design Practical Research Question How is the bounce-height of a ping pong ball affected by it’s temperature? This research questions aims to find out how the temperature of a ping pong ball affects the vertical height bounce‚ after being dropped from 1 metre. I will be measuring the bounce height using a video camera to find the heightest point. I will use the top of the ball for ease of results. Hypothesis:
