An Experiment on Nitrogen Fertilizers. Experiment with other types of nutrient fertilizers to test their effects on plants. Stone Cactus Mix. Then, pour water into each of them and harvest whatever "groundwater" drips out. By referring to numerous empirical experiments under Australian soils such as Kandosols, Passioura (1991) suspected that roots growing into large-sized biopores could be detrimental for plant. My hypothesis was wrong, because I thought the mixture soil would grow the best, but actually the plant in the sand grew the quickest. See which plants grow the most quickly, and check which plants look the healthiest are the leaves all the same colour? Test how fruits ripen, plant seeds, grow a garden in water, or start with plantlets rather than seed. OBSERVE: Which cup has standing water after a minute?

To get started, create three miniature milk-carton landscapes: one with living plants, one with dead leaves and sticks, and one with no plant matter at all. For example, you could measure the height, width, number of leaves, how fast the plants grow, number of flowers or yield of seeds or fruits. My final stem growth results were the following. This experiment looks at the effect that different growing mediums sand, soil, compost, and bark have on the plants, as well as what happens when plants get too much water. Soil differences are the result of different mixtures of these particles. Take a soil thermometer (Fig. The purpose of this experiment is to observe differences between the plants as they grow in different soils. But the spectrum of light most utilized by a leaf is limited to three distinct colors, red, blue and yellow. Making Everyday Objects Out of Mushroom roots!

Particle sizes are categorized as clay (small particles), sand (large particles), or silt (particle size between clay and sand). Since we already discussed that plants need water to grow, we first tested different types of water to see if it made a difference. Many classrooms do this basic bean plant experiment to examine the stages of the growth of a plant. 2. Make a hypothesis about which part of the light spectrum causes the most plant growth and which part of the light spectrum causes the least plant growth. Aiden and I set up and experiment to test which soil substrate will grow the best plant. This allowed the stem to rise easily out of the soil, and it allowed water and nutrients to move easier through the soil to the roots. Learn to measure plant growth accurately. Results: The purpose of this laboratory experiment was to determine the effect of different fertilizer concentrations on the growth of radish plants. Garden soil tends to get waterlogged and compacts in the pot, so the roots may have too much water, which can make them rot, and may also not have enough air. Zinc-solubilizing bacteria (ZSB) have potential alternates for enhancing the bioavailability of zinc in soil. The beans planted in the potting compost in the cup with drainage holes are likely to be the tallest and look the healthiest, with large dark green leaves, because potting compost drains well, so that the plants dont become waterlogged, but holds enough moisture to keep the plants healthy. Because of this, bean plants grown in sand can be short and stunted, and might be pale. Place your jars in a sunny location. When the pot with potting compost and drainage holes starts to dry out, water them all with the same amount of water, and make sure that they all get the same amount of light.
