Distance of a Seeds Distribution by Wind Introduction Seeds can be distributed three main ways: wind‚ water and animals. In this experiment‚ wind will be tested due to the fact that wind can be controlled in an indoor environment and can carry seeds farther and longer in the air and bring the seeds to a new area to grow. There are many types of seeds that travel through the air in a unique way. One way seeds can travel is through gliding‚ which is having two lateral wings that look like one of

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 them into two

Chlorophyll Extraction This easy science project shows simple and efficient method of chlorophyll extraction from a plant. This is only a demonstration of working method which can be refined and used for a full scale science project. Plants contain many pigments in different proportions. For flowering plants it’s mostly a combination of chlorophyll-A‚ chlorophyll-B‚ pheophytin and Carotenes. These pigments have shades of green‚ blue green‚ grayish‚ and yellow-orange. Their concentration is

An Increase in Light Intensity Increases the Rate of Respiration M. Chauntise‚ S. Shaika‚ R. Shantal INTRODUCTION The sun plays a vital role in sustaining an entire living world whether indirectly or directy using a transformation process called photosynthesis. This process assists in nourishing plants and keeping them alive. For example‚ trees grow very tall in the rainforest where there is an abundance of water in order to reach as much light as they can. For this reason‚ in order to survive the

Through careful observation‚ we identified the various parts of a light microscope we found that the light microscope Ocular lenses which give 10x magnification power‚ and objective lenses which consist of three objectives: scanning

GLENDA MARIE GARCIA POLARIZED LIGHT LAB REPORT EXPERIMENT # 5 June 27‚ 2014 PHYS 1417 ABSTRACT Ordinary light such as that from a light bulb is a form of wave motion that consists of electrical and magnetic fields that vibrate at right angles to the direction of travel of a light beam. Light waves that vibrate in a single plane are called polarized light waves. Such waves can be produced by passing light through polarizing filters. The experiment conducted was composed of crossed

Wavelength and Light Intensity on Photosynthetic Activity ABSTRACT The photosynthetic process of eukaryotes revolves around chlorophyll‚ the substance that give plants their green color. Plants convert light energy into chemical energy by means of photosynthesis. This experiment tests the reaction rates of a chloroplast suspension against variables of wavelengths and light intensity. Both a control and an experimental cuvette were exposed to a range of 450 to 750nm of light and varying intensities to test

that light exercise has on different cardiovascular functions such as mean blood pressure‚ cardiac out put‚ and total peripheral resistance by comparing both of the numerical values before and after exercise. Prior to exercise‚ the mean blood pressure (MBP) was 86.8 mmHg with a standard deviation of 7.4. After exercise‚ MBP was 96.3 mmHg with a standard deviation of 9.2. The cardiac output (CO) was 5.3 Liters/minute with a standard deviation of 1.0‚ but the CO was 8.3 Liters/minute after light exercise

Light Lab Introduction: The purpose of this lab is to observe how influential light is to the construction and/or use of CO2 and O2 amongst plants. This can be examined by experimenting the effects of plants under both light and no light. In order to begin this experiment you must begin by wrapping the “BioChamber” with aluminum foil to prevent light from coming through to the leaves‚ however‚ once the lid has been covered you are to poke holes so you can insert the sensors. Next‚ you will

fluorescent light and why ultraviolet light is required to visualise it. (5 marks) When GFP is hit with UV light‚ the chromophore is hit by a photon. This changes the chromophore from ground state (A) to A*‚ which is a highly excitable state. Due to such a highly excitable state not being able to remain so for very long‚ the A* state chromophore emits a proton‚ lowering its state to I*‚ the energetic I. This I* state chromophore lowers its energy by emitting a photon of green light‚ lowering its
