Each element emits a unique color light. The purpose of this experiment was to observe these unique colors and calculate their energy. In order to observe this‚ we placed the physical elements in a 24 well plate‚ dipped wet q-tips into the wells to gather the element‚ and put it over the bunsen burner to observe the flame emitted. While observing the different flames‚ we saw that different elements did indeed emit unique flame colors. Colors such as red‚ violet‚ and turquoise were emitted. All of

Everything except the comb was made of ¼ inch Acrylic Plexiglass. The glass helped the group see what was going on in the experiment. The comb was 3D printed to be more accurate. One material was a casting tray which held the Gel in future steps.

because blue light has a higher absorbance by plant photosynthetic pigments and has a higher energy wavelength than red light‚ we predicted that juniper needles placed in blue light would photosynthesize faster than juniper needles placed in red light. We measured the rate of change in CO2 concentration due to juniper needles. For each sample‚ we placed the needles into a chamber connected to the CO2 monitor and measured the rate of change of CO2 concentration for 10 minutes under red light and then

Light Transmission Through Liquids With Different Viscosities Introduction Aim This experiment investigates the effects of different liquid viscosities on light transmission. The results of this experiment could greatly benefit marine biologists or other marine scientists. This would help them figure out how their flashlights would work in different water conditions in the ocean. Background Research Spectrophotometers are devices that measure the amount of light absorbed by a certain liquid

muscle cells and analyze for presence of myosin light chain. Utilizing Western Blotting techniques and using specific antibodies helped to detect myosin light chain. The hypothesis was that proliferating myoblasts could be induced to initiate the differentiation process by depriving the cells of the necessary growth factors and that the differentiation is characterized by the expression of muscle-specific proteins. The results showed that that myosin light chain was not present. It was concluded that

temperature on the rate of movement of woodlice Aim: The aim of this experiment is to establish whether a change in temperature affects the rate in which woodlouse move. I measured the rate by timing the woodlouse to move a set distance of 20cm‚ and altered the surrounding temperature by submerging a clear tube in water with different temperatures controlled by a water bath. Research: It is to be believed there over 3000 different species of woodlice‚ a total of 42 species have been recorded

The aim of this investigation is to see whether I can find a definite relationship between the light intensity onto the leaf’s surface and the surface area of the leaf. Hypothesis I think the light intensity could affect the surface area in the following way: ·A higher light intensity could make the surface area of the leaf larger. The reason I think a higher light intensity could make the surface area larger is the fact that there would be a larger amount of chlorophyll‚ containing chloroplasts

Light Reflection and Refraction Pre-Lab using PhET I) Introduction: When a light ray strikes a smooth interface separating two transparent materials (like air‚ glass‚ or water)‚ the wave is partly reflected and partly refracted (or transmitted) into the second material. For an example of this‚ imagine you are outside looking at a restaurant window. You can probably see both the inside of the restaurant (from the refracted light) and some of the street behind you (from the reflected light). Similarly

Light I | | INTRODUCTION | Light‚ form of energy visible to the human eye that is radiated by moving charged particles. Light from the Sun provides the energy needed for plant growth. Plants convert the energy in sunlight into storable chemical form through a process called photosynthesis. Petroleum‚ coal‚ and natural gas are the remains of plants that lived millions of years ago‚ and the energy these fuels release when they burn is the chemical energy converted from sunlight.
