in a significant and convincing change in the speed of the wave? Hypothesis: Changing the frequency of the wave will not result in a change in speed because the wavelength will change proportionally as in theory. Student Designed Investigation Procedure/ Planning Procedure: 1. Three students would get into a group. 2. A Slinky would be spread along a table or along the floor and set up as it shows on the diagram above for about 4 meters. 1. For proper data‚ the length of the floor was

investigate the effect of temperature on the enzyme catalase. The original research question was exploring the effect temperature would have on a yeast catalase reacting with hydrogen peroxide (H2O2). To address the latter question a series of experiments were conducted. The various temperatures experimented with were as follows: 22 degrees Celsius (room temperature)‚ 0 degrees Celsius (freezing)‚ 100 degrees Celsius (boiling)‚ and 37 degrees Celsius. Along with variations in temperature‚ the experiment involved

for the effects of temperature on catalase activity. Introduction: Enzymes are proteins that act as catalysts and help complex reactions to occur everywhere in life. Enzymes affect a chemical reaction by acting as a catalyst‚ which is to say‚ it speeds up the reaction. However‚ extreme ph and temperature hinders enzyme function. Optimal activity of an enzyme is the optimal environment that an enzyme requires to function‚ which means having the optimum ph and temperature to catalyze a reaction

Temperature Affecting Enzyme Activity Introduction The basic properties of life revolve around chemical reactions. Without the presence of enzymes some of life’s processes would not come so easily. Enzymes are basically proteins‚ which have specific shapes for different substrates. Enzymes change the rate in chemical reactions. It does this without having to change its own shape‚ which makes enzymes different from other proteins. A common enzyme that we have is catalase‚ which breaks down

Speed Dating Tips and Questions Successful speed dating requires a little preparation and care given to the questions that you intend to ask. THINGS TO AVOID Do not drink before or during the event. Overdrinking is a turn-off for most people‚ and using it at a speed-dating event risks making the evening into an embarrassing situation. Do not attend a speed-dating event held at a place where you spend considerable time. Seeing friends at the event but not participating is a stressful experience

The two articles‚ “What Happens To Your Body When You Freeze To Death” by Katherine Ripley and “Hypothermia- Cold Weather Health Risks” both identify the effects and stages of hypothermia. The videos‚ “What Hypothermia Does to Your Body and Brain” and “The Effects of Hypothermia” provide even more information about what your body experiences during hypothermia.

The relationship between the size of the woodlice and their speed Abstract: How does the physical makeup and size of an organism relate to various activities an organism perform is a topic many people curious about. We wanted to find out if there was any relationship between the body size of woodlice and their speed. We hypothesized that the bigger woodlice have higher speed than smaller woodlice. We conducted an in-class experiment to test our hypothesis. We took ten woodlice and divided
