goal of this lab? What question is it trying to answer‚ or what problem is it trying to explain? The goal for this lab is to be able to get the boiling water’s temperature to increase by adding table salt. The problem it is trying to explain is‚ how does table salt affect the boiling temperature of water? does it increase or decrease? or does it stay the same? Hypothesis After reading the lab instructions - but before starting the lab - record your best “educated guess” about what will happen

Effect of Humidity on Transpiration in Plants Problem/Aim How does placing a plant in a more humid location for 50 minutes affect its rate of transpiration? Introduction Transpiration is the loss of water from a plant‚ mainly through the stomata of leaves. Darkness‚ internal water deficit‚ and extremes of temperature tend to close stomata and decrease transpiration; illumination‚ ample water supply‚ and optimum temperature cause stomata to open and increase transpiration. Its exact significance

hear and are caused by vibrations that travel through mediums. Depending on the medium and temperature‚ the time it takes for sound waves to travel vary. The hypothesis states that if the temperature in the air increases‚ then the speed of sound will also increase because faster-moving particles transfer energy quickly. The data collected supports the hypothesis. Therefore‚ increased air temperature affects the speed of sound because the molecules move faster‚ which causes the energy to be transferred

What affect does exercise have on these parts of your body? Heart‚ Lungs‚ Muscles‚ Joints and Body Temperature? After exercise‚ you’ll find your body experiences immediate and more gradual effects. The minute you start training‚ you’ll notice more frequent muscle contraction‚ raised body temperature and pulse‚ and deeper breathing known as tidal volume. Longer-term effects occur as the body adapts to regular exercise‚ including your heart getting larger‚ bones becoming denser and the vital capacity

environment that is rainy and humid. The rain forest only has one season because it’s weather and temperature never change. The temperature never changes because of the high humidity rate and waters thermal resistance. The rain forest has direct sunlight that provides light and heat but indirect only provides light. Rain forests have an average temperature of 80 degrees fahrenheit. The temperature may feel hotter due to the high humidity rate. Rain forests can receive 100 to 300 inches of rain

Variable was the heat lamp‚ and the dependent variable was the temperature of the soil‚ because the temperature varied based on whether the heat lamp was turned off or on‚ and whether there was extra water added or not. Our hypothesis was proven correct‚ because the dry soil’s temperature was hotter than the damp soil’s temperature when the heat lamp was on‚ but then it decreased when it turned off‚ while the damp soil’s temperature remained the same. This is because dry soil contains little moisture

Transpiration Formal Lab Report By Jessica Tran Introduction When water is transported from the roots to the mesophyll cells in the leaves‚ it is evaporates out the stomates‚ called transpiration‚ to create a lower osmotic potential. Osmotic potential is the part of the water potential of a tissue that results from the presence of solute particles. Even though the stomates open to release water‚ it also brings in carbon dioxide to produce sugar and oxygen through a process of photosynthesis

Caffeine stimulates receptors located in cells within your heart to increase your heart rate. Effects of this stimulation speed up your blood flow because of an increase in heart rate‚ as well as an increase in blood sugar‚ urine production and body temperature. Function Physiologically‚ caffeine stimulates the receptors within your heart to beat faster by blocking the enzyme phosphodiesterace. Phosphodiesterace works together with another enzyme‚ cyclic AMP‚ to keep your heart rate at its normal range

AIMS The aim of this experiment was to investigate the effect of temperature rise on the rate of transpiration of a plant (hibiscus) by measuring the plant’s water uptake in a period of time. HYPOTHESIS Transpiration is the process by which plants loses water to the atmosphere from their leaves. Water in the plant is lost to the atmosphere by evaporation. Evaporation of water can occur at any temperature. In the presence of sunlight‚ water in the plants evaporates into the intercellular air
