SCIENCE REPORT AMMONIUM NITRATE NH4NO3 Problem Our task was to investigate what the optimum ratio of solute to solvent that will produce the maximum cooling/heating effect? Hypothesis With a smaller quantity of water (50mls) and the same amount of Ammonium Nitrate added. After any period of time the mixture will be a cooler temperature than that of a mixture with a larger quantity of water. Variables X Water X Teaspoons X Time X Ammonium Nitrate X Thermometer X Stirring

Ceratopteris Fern Growth and Analysis: Observing Germination and Effects of Ammonium Nitrate Treatment I: Abstract Observing the effects of ammonium nitrate has on the germination days of C-Fern gametophytes by constructing an experiment with two spore-sown petri dishes‚ one control and one treatment – a normal nutrient-rich agar petri dish and an ammonium nitrate-containing petri dish respectively. The two petri dishes were each inoculated with three drops of spore suspension

nitrateAmmonium Nitrate How they are manufactured? Ammonium nitrate is made commercially by passing ammonia gas (NH3) and a water solution of nitric acid (HNO3) through a pipe. The ammonia combines with the nitric acid to form ammonium nitrate. The formula for this reaction can be written as NH3 + HNO3 → NH4NO3. Large amounts of heat are released during the reaction‚ so the pipe and supporting equipment must be very strong. The solution of ammonium nitrate in water is allowed to evaporate‚ leaving

Germination is the process by which a plant grows from a seed. The most common example of germination is the sprouting of a seedling from a seed of an angiosperm or gymnosperm. However the growth of a sporeling from a spore‚ for example the growth of hyphae from fungal spores‚ is also germination. In a more general sense‚ germination can be simply anything expanding into greater being from a small existence or germ‚ a method that is commonly used by many seed germination projects. Seed germination

IRP 3: Germination Introduction: Germination is the process of which a plant of fungus emerges from its seed or spore. Germination involves activating the seed’s metabolism‚ which is done through numerous stages. The fist stage involves the rehydrating the cell by absorbing water. This allows the cell to become metabolically active. After water absorption‚ gibberellin is produced in the cotyledon of the seed. The enzyme gibberellin stimulates the production of amylase‚ which catalyzes the

Ferns and Their Relatives -What is a Fern? Fern is a flowerless plant that has feathery or leafy fronds and reproduces by spores released from the undersides of the fronds. Ferns have a vascular system for the transport of water and nutrients. *Characteristics of Seedless and Vascular Plants: Includes: ferns‚ club mosses‚ and horsetails Have vascular tissue They are able to grow bigger and taller Within vascular plants is the phloem‚ the vessel that transports food‚ and the xylem‚ which transports
