If the plant collects too much water, it will cause the roots to rot, resulting in the plants not being able to receive enough oxygen from the soil. Therefore, because a plant cannot grow if it doesn’t have healthy roots, the balanced amount of water will result in the best seed germination. Independent variable: - The amount of water used when planting the 60 seeds (bean sprouts) Dependent variable: - The number of seeds that germinate Controlled variable: - The amount of petri dishes- 3 petri dishes will be used in this experiment - The amount of cotton wool- Each petri dish will have 1g of cotton wool laid out on the bottom - The type of seed/bean- There will be use of only one type of seed/bean throughout this whole experiment - The number of seeds- There will be 20 seeds/beans in each of the petri dishes The location where the petri dishes- The petri dishes with the seeds/beans and cotton wool will be kept in the open cupboards of the science classroom, throughout this whole experiment - The method- The same method will be repeated several times, just with different amounts of water (5mL, 10mL, 15mL) Materials and Equipment: - 3 petri dishes (The three dishes where the bean sprouts will be grown, kept and watered) - 60 seeds (bean sprouts), 20 seeds (bean sprouts) in each of the three petri dishes - 3g of cotton wool (1g of cotton wool will be laid on the bottom of each of the three petri dishes) - 30mL of water
MATERIALS AND METHODS In order to determine if seeds subjected with more then .5ml of the environmental contaminate ammonium hydroxide will not show growth of the plant T.aestivum, some items are needed. Some of the material are as follows; potting soil, ten soil pots of the same size and material, one hundred T. aestivum seeds, 500ml of water (50ml on each pot), a dropper, 10 ml of the household cleaner ammonium hydroxide, 10 labels, a 50ml beaker, marker and a green house. First we got ten soil pots and placed them in two rows of five pots (trial 1 and trail 2). Then we place a label on each of the potting soils. We used a marker and label the labels on the first row Plant A Tr1, Plant B Tr1, Plant C Tr1, Plant D Tr 1, and Control 1.
12 Mung Beans (6 per bottle) 10 Ml of water per bottle per day. A ruler to measure your plants each day. (cm) A data table to collect all the data you gather over your 10 day time period. Procedure: Follow the following steps: Step 1- Get 2 clear 2 liter bottles. Step 2- Clean out both 2 liter bottles for any excess soda, water, etc.
Place the petri dishes in a sealed plastic bag, taking care to not shift the seeds too much. 6. Check on the seeds daily to see if the seeds need more water. If so, spray each dish with its appropriate salt water concentration. 7.
Bean Plant Growth Aim: To determine which of the following liquids has the greatest effect on the growth of bean plants: Water, Salt Water (solution 1:5), Sugar Water (solution 1:5), Vegetable Juice or Cola. Background Research: Hypothesis: That water will have the greatest effect on the growth of the bean plants. Anti Hypothesis: That water will not have the greatest effect on the growth of the bean plants. Equipment: * Bean Seeds * Potting Mix * Water * Salt * Sugar * Cola * Vegetable Juice * Millimetre Ruler * Measuring Cup * Plastic Cups * Scales Independent Variable: Dependent Variable: Controls: The amount of solution used; the amount of potting mix; place where plants were grown Method: 1. Collect 5 plastic cups/small pots and poke holes in the bottom of the cup so the liquid can drain out.
8. Then average the height of each cup. V. Data Chart: Cup Number Number of Seeds Number of Sprouts Average Height 1 1 1 24.70 cm 2 2 2 27.25 cm 3 4 4 27.50 cm 4 8 8 25.23 cm Graph: VI. Analysis From the data collected throughout conducting the Mung Beans Experiment, I can assume that mung beans grow better in areas more populated with other mung beans. The cup with only one mung bean seed in it produced the shortest plant of the four cups.
Kevin Guillermo Period 2 THE GREY WATER LAB: A LOOK AT THE EFFECTS OF GREY WATER ON CHERRY BELLE RADISH SEEDS Purpose: To study the effects of various concentrations of grey water on the growth of Cherry Belle Radish Seeds. Background Information: Greywater gets its name from its cloudy appearance and from its status as being between fresh, potable water (known as "white water") and sewage water (“black water"). In a household context, greywater is the leftover water from baths, showers, hand basins and washing machines only. Some definitions of greywater include water from the kitchen sink. Any water containing human waste is considered black water.
Brief Explanation This experiment will test the effect of caffeine on the growth of mung bean plants. By testing this, I can also prove the effect of caffeine on all other organisms. The experiment could go either way: the plants with caffeine could grow more or they could stop growing once I add the caffeine in to the equation. * Independent and Dependent Variables * The independent variables are the watering solutions which are water, caffeine solution, and coffee mixture. The constants are the size of the pot, the concentration of caffeine and coffee, the amount of sunlight, the temperature of the environment (which will remain at room temperature) and the amount of water added daily.

We will experiment to see if beans can be grown in a soil with varying levels of salinity (salt). In real life, sea spray often affects the ability
