  • Bulk Density And Porosity Lab Report

    Laboratory Report 2: Soil Texture, Bulk density and Porosity Introduction Soil Texture The classification of soil texture is determined by the percentage of each of the soil separates. Soil separates are mineral particles smaller than 2mm, and these particles are sand, silt and clay. These textures are separated by the size of the particles, with sand being the largest between 2mm and 0.05mm, silt at between 0.05mm and 0.002mm, and clay at <0.002mm. The size of the particles influences the…

  • Plant Science Seed Germination Lab Hypothesis

    Plant Science - Seed germination and growth The research question: What is the effect of changing the pH of the soil on the germination and growth of mustard peas? Hypothesis: The greatest number of peas will germinate and will grow the most when the pH is 5 or 7. Theory: Enzymes play a vital role in the cells of plants (especially when growing) and enzymes work best when at their optimum pH value. Moreover, all chemical reactions have an optimum pH at which they work best (Howard and…

  • Earthquake Lab Hypothesis

    Science Fair Purpose The purpose of this experiment is to find out which type of soil amplifies side-to-side shaking the most in an earthquake. Hypothesis My hypothesis is that sand will amplify the shaking the most because, liquefaction loosens up the soil which can make buildings slide. Materials To build your shake table, you will need: Packing tape Coffee can lid, or any flat plastic lid with approximately 3/8" lip that can fit under the shake table tray Marbles, or any small balls of the…

  • Landscape Function Analysis Of Mulloon Home Farm

    Mulloon institution to us. Then we started our research with Forest LFA, including landscape organization assessment (LOA) and soil surface assessment (SSA). Firstly, we set up a 50m transect running directly up and down the slope and mapped patches and interpatches on this transect. We regarded the place where resources could be accumulated as patches, like grass, shrubs, logs or trees. Then we made soil surface assessment by choosing 3 points in each patch type randomly and collecting 11…
