Cellular Respiration Purpose The purpose of this experiment was to determine the effect of body mass and temperature on the rate of respiration in the mouse. Hypothesis When the temperature is reduced‚ cellular respiration will increase. Measurement Weight the mouse and use soda lime for mouse to perspire. Oxygen was inhaled and carbon dioxide was exhaled. Carbon dioxide was absorbed by soda lime. Rate of respiration was measured in terms of ml of oxygen per min over grams. General

fertilized already. Their plants aren’t grow . So she decided to experiment on what is the effect of watering on plant growth. 2. Observation/Research: She water them every day‚ they have good soil‚ and they’re in the shade. 3. Formulate a Hypothesis: Sarah think plants will grow better if they’re in the sun‚ than in the shade. The greater the amount of water‚ the faster the growth. 4. Independent variable : The independent variable in this science fair project is the amount of water used

It was evident since the start of the lap that the big question was‚ how does temperature affect radish germination. The original hypothesis was if temperature affects the tail length of the germinated seed‚ then a higher temperature will lead to a significant decrease in the tail length of the germinated seed. This hypothesis is true‚ according to the collected data. After 6 days of letting the seeds germinate‚ the ones that germinated in room temperature were quicker to germinate and with a lot

What is Photosynthesis? Its general reference is sunlight protons converted into resourceful energy‚ of which are autotrophs that work and feed themselves independently. To be more scientific using its equation 6CO2 + 6H2O – Sunlight Energy – C6H12O6 + 6H2O‚ carbon dioxide particles travel through a leaf’s cell surface‚ which is where the chloroplast organelle produces “chlorophyll molecules forming a light harvesting complex absorbing that energy‚ exciting electrons” ((n.d.).

of most red fruits (like apples) and almost all red leaves during the autumn. Anthocyanins absorb light in the blue-green wavelengths‚ allowing the red wavelengths to be scattered by the plant tissues to make these organs visible to us as red. Hypothesis: If we test the Red Wandering Jew leaves for pigments then we will find anthocyanin in the leaves because there is purple in the leaves. Control Variable:

Ask a Question‚ Do Research‚ Hypothesis‚ Test Your Hypothesis by Doing an Experiment‚ Analyze Your Data‚ Draw a Conclusion‚ And Communicate Your Results. 3) Why do scientists use the scientific method? What are the benefits of using it? Scientists use this method to have a formula to back up their findings‚ and to explain how they came to the conclusion. The Scientific method is a good way to find the solution to a problem. 4) In what Form is a proper hypothesis written in? What are the rules

types of cacti were observed: organ pipe‚ prickly pear‚ and saguaro. The organ pipe contains no leaves and has narrow stems that carry out photosynthesis and store water. Neither the saguaro nor prickly pear cacti have leaves‚ but both have a highly modified form of a leaf called the spine. Spines are highly modified leaves because they do not carry out photosynthesis. Spines protect the plant from predation and prevent water loss as stomata in leaves are highly susceptible to water loss. Fruit trees
