Vegetation gives off heatresulting in this circular snowmelt pattern. Ground heat flux is the energy delivered to the snowpack from the soil below by conduction. Radiation inputs to the snowpack include net shortwave solar radiation including visible and ultraviolet light and longwave infrared radiation. Net shortwave radiation is the difference in energy received from the sun and that reflected by the snowpack because of the snowpack albedo.

Thank you for your input. Safety Issues The investigator should be reminded to use matches safely. Once a match is used it should be discarded properly. If the investigator blows out a match and throws it in the trash, there is a danger that it might not be totally extinguished. To reduce this risk wet the used match head thoroughly with water than discard.

Material Availability The materials required for this project are readily available. Approximate Time Required to Complete the Project 2 Days This project focuses on the production of oxygen by plants during the photosynthesis process.

The research aspect of this science fair project is to assess how light intensity affects the rate at which photosynthesis occurs and the rate of oxygen production.

The project investigator will place a sprig of elodea underwater plant under a clear funnel then fill a test tube with water and it placed on top of the funnel. This entire setup will be placed in a larger container of water.

A light source will be placed at different distances from the test plant.

The gas given off in the form of bubbles will be collected in the test tube and tested for the presence of oxygen. From the observations and tests made a data table will be generated and results displayed in the form of a graph.

Elodea water plantlight source 40 Watt bulb and sockettest tube or long slider empty bottledistilled water, tape, baking soda, a clear plastic funnel, thin piece of wood, metric ruler, and long stick matches.

With the possible exception of the elodea plant and a test tube, all the other items can be purchased from the local supermarket, hardware, homebuilding or big box retail Wal-Mart, Target, etc store.

The elodea underwater plants can be purchased from a pet supply store, and a test tube can be borrowed from a high school science teacher or found in a toy chemistry set.

Photosynthesis is the process by which plants use the energy in sunlight to synthesize material from air and water for growth. Photosynthesis is the building up of sugar molecules using carbon dioxide and water as the raw materials.

The energy for the process comes from light and a green pigment called chlorophyll which allows the plant to transfer the energy from light to sugar.

The chemical equation for this process is shown below.

This test plant setup See Figure 1 is placed in room with no light and then it will be exposed to light with varying degrees of intensity based on distance. While exposed, the plants will produce a gas which is collected in an inverted test tube.

Figure 1 After enough gas has been produced and collected, the test tube will be removed, and inverted, and a glowing piece of wood is inserted into the tube. The wood should burn more rapidly in the oxygen gas in the test tube than in the air.

The behavior of the glowing piece of wood will show that the gas produced by the plants is oxygen. The fact that no gas was produced while the setup was kept in the dark showed that light was the cause of the production of oxygen.

The increases in bubbling gas production as the light source is moved closer to the plants indicate that the rate of oxygen production by the photosynthesis is affected by the intensity of the light source.

Digital photos can be taken during the experimenting process andthe following websites offer down loadable images that can be used on the display board:Engaging multimedia resources to teach about viruses, the immune systems, and infectious disease.

Photosynthesis is the process used by plants, algae and certain bacteria to harness energy from sunlight into chemical energy. There are two types of photosynthetic processes: oxygenic. Photosynthesis & Respiration What is Photosynthesis?

Plant Energy Transformations-Photosynthesis

The process of photosynthesis is a chemical reaction. It is the most . Photosynthesis Grade 3 The student will: Learn what photosynthesis is and how it helps plants.

Learn what a plant needs for photosynthesis. What is photosynthesis? Plants make their own food. This process is called photosynthesis. Where does photosynthesis occur? Photosynthesis occurs in the leaves of a plant. Document presentation . Sep 18,  · PhotosynthesisThe Value of PhotosynthesisThe importance of photosynthesis on Earth is it keeps everything alive.

It creates food for itself, it is food for other living things, and they are food for other living things. It also gives out oxygen to grupobittia.com Takes EnergyDuring photosynthesis, there is an energy transformation.
