Water is imperative for the growth and preservation of life‚ especially plants. Playing a role from the vary beginning‚ water is necessary in the germination of dry seeds and growth of plants throughout their life cycle. However‚ there are drawbacks to an overabundance of water or a lack of water. Therefore‚ how much water is required to maximize the potential of a given crop? In our experiment‚ we examine the effects of water on corn. Corn is a vital crop to North America‚ and there is a wide draw

Effect of all-natural bath and body wash on millet seed growth. This experiment was conducted to determine what effect a household chemical would have on the growth of a plant. Everyday multitudes of chemicals are washed down the drains inside of our homes; many of these same chemicals are then being introduced into the environment through our water sources‚ such as rivers. This experiment will test the effect of all-natural bath and shower gel would have on the growth cycle of millet seeds. The

Purpose: How will salt and plain water affect plant cells? Hypothesis Clear water: If you place carrots and celery in plain water they will become flaccid and then eventually start to loose its colour and pieces of the celery or carrots will fall off. I know this because the vegetables will continue absorbing water putting the vegetable in a hypotonic solution. Pieces of the vegetable could break off because the cells are not getting what they need. The cells need to create glucose and oxygen

The experiment began using a TI-84 calculator as a random number generator‚ and 1-4 inputted into the calculator to determine order. Numbers 1-3 were inputted to determine the order of experimental groups for the participant. A plastic tub was then filled with a liter of water at 25℃‚ and a thermometer was placed into the water to verify. The

Materials: 1. 2 Plastic cups 2. Tap Water 3. Teaspoon 4. Bag of salt 5. Freezer 6. Clock 7. Paper 8. Pencil Procedures: 1. Take plastic cup and pour in one cup water in each 2. Take one teaspoon of salt and mix it in one of cups 3. Put both cups in the freezer 4. Observe. Conclusion: When salt is added to water it slows the freezing process down‚ therefore the freezing point of tap water is higher than the freezing point of salt water. Hypothesis: If... ‚ then...

The turbidity was taken with a Turbidity sensor and a Secchi disk icon. A bottle of water was inserted into the turbidity sensor‚ where light was refracted through it. This picked up on the cloudiness and the debris in the water. The disk icon tested the water by adhering the sticker to the bottom of a jar and filling the jar with water. The appearance of the disc would change to show the turbidity levels in the water. The temperature was measured using a thermometer. Lastly‚ the Flow Rate was calculated

Biology Digestive Enzyme Experiment “Design an experiment in which you will investigate a digestive enzyme’s effect on digestion” Research Question: To determine the effect of enzyme concentration on the rate of digestion. This will be done by increasing the concentration of the enzyme diastase and investigate its effect on the rate of starch digestion. The rate will be determined by the amount of time it takes to completely digest the powdered starch‚ the complete digestion will be indicated by
