We first labeled each cup with what type of water we were going to use. We put an equal amount of soil into each cup. Our next step was to put exactly 20 seeds into each cup approximately ¼ inch deep. After that we poured 20ml of each type of water into its designated cup. After the grass started to sprout we measured its growth in centimeters and then gave each cup its 20ml of water.
Water the seeds daily until the grass is at least 1.5 inches tall. Take 20 seeds from a rapid growing weed plant and evenly plant 10 in each box. Water the grass regularly until weeds start to grow throughout the grass. Follow directions for each weed killer and apply is to the boxes of grass/weeds. Make sure to use the same amount of weed killer in each box.
Paper chromatography can be used in separating amino acids and anions, RNA fingerprinting, and testing histamines and antibiotics. (Infromation received from sonic.org Purpose The purpose of this experiment was to separate the dyes that these markers are composed of and show how chromatography works. Materials * Four different markers (including one black permanent marker) * Rubbing alcohol or isopropyl alcohol * Coffee filters (2) * Tall glasses or plastic cups (2) * Pencil * Ruler * Tape * Table salt * Water * Measuring cups/spoons * Clean pitcher or 2-liter bottle Procedure 1. Your first task is to cut the coffee filter into a rectangle measuring three cm by nine cm. You will need 2 for this lab.
HYPOTHESIS My hypothesis is that the stem of each plant will be attracted to the magnet. I think that the magnet will pull the plant's root causing it to grow away from the magnet. I base my hypothesis on my research that states that plants have different kinds of tropisms that attract to different things and cause the plant’s roots to grow downward. I also based it on the fact that magnets attract to some things and repel to other things. EXPERIMENT DESIGN The constants in this study are: How much water the plant receives How much soil is in the pot How much light the plant receives What the growing temperature is When the seed is planted How many seeds are planted in each pot Where each seed is planted How deep each seed is planted How big the pot is How far from the light the pot is The temperature of the water What time the light is turned off and on The manipulated variable is whether a magnet is being used and where the magnet is placed.
When the roots are good and thick and the stem has leaved out, your avocado is ready for potting. Use a terracotta pot with a top diameter of about 10 inches. Put broken crockery around the drainage hole in the bottom of the pot and fill with soil rich in humus, leaving enough space for the seed and roots. Place the seed gently on top of the soil, taking care not to injure the roots. Carefully add soil until the seed is half covered, but do not tamp it down.
Experiment & Observation I gathered together my items; distilled water, salt, ruler, scissors, stapler pencil, tape, 16 toothpicks, Kool-Aid drink mix strawberry and grape, set of McCormick food coloring red, yellow, green and blue, small bag of M&M candy, plastic beaker 50 mL, petri dish 60mm, well-plate 24, FDC blue dye #1 0.5 mL vial, FDC blue dye #2 0.5 mL vial FDC red dye #3 0.5 mL vial, FDC red dye #40 0.5 mL vial, FDC yellow dye #5 0.5 mL vial, FDC yellow dye #6 0.5 mL vial, unknown 0.5 mL vial, 3 filter paper chrom 14x7 cm. I first made a solvent using a 50 mL beaker with warm room temperature distilled water and a pinch of salt. I made sure the salt was completely dissolved and set the solvent aside. I took out two of the Chromatography filter paper sheets 14x7 and with a pencil very lightly drew a horizontal line 1 cm from the bottom of both sheet. Then horizontally on the line I just drew I marked off 9 spaces 1.5 cm apart.
Materials & Methods Materials: · Scale · 4 6” Dialysis Tubing · 4 Transfer Pipets · Sugar · Scissors · Rubber Bands · 4 Same-Sized Coffee Cups · 250ml Graduated Cylinder · Tape Measure · Sauce Pan · 3 600ml Containers · Plastic Covering · Spoon Methods: 1.) Place 4 6” pieces of dialysis tubing into coffee cups full of tap with and leave them for two hours prior to beginning the experiment. 2.) As you wait, prepare your three sugar solutions. For the first solution, pour 5 grams of sugar into 250ml graduated cylinder and add water up to the 250ml mark.
READ THIS LAB BEFORE COMING TO CLASS. Introduction: In this lab exercise we will study the effects of an abiotic (non-living) factor on seed germination (the beginning of seed growth which is usually seen with emergence of a small white root). We will also be stressing the use of graphing skills. We will use a common seed available in grocery stores, red kidney beans. These plants do not live near the sea normally.
Pour hot agar into dish 4. Keep lid off and let agar steam 5. Put top back on and let plate cool 6. Collect piece of bacteria by dabbing it with moistened cotton 7. Dab contaminated cotton onto section of the dish 8.
Hypothesis: Corresponding to the theory of composting, it is more than possible that a cup filled with organic matter, leaves, water, and soil will be decomposed from at the end of a fourteen-day period, producing and organic mixture rich in nutrients, that will help the nourishment of my garden, and small orchard in my mom's backyard. • Plastic Cup • Scissors • Plastic wrap • Camera • thermometer • Notebook • Vegetable scraps • Fruit scraps • Egg shell • Soil • Grass clippings • Leaves • Water Procedure: Made holes on the bottom of the plastic cup with a scissors, and placed of the organic matter on a bowl and mixed with a plastic spoon. At the end, I made a little hole on the plastic wrap and introduced the thermometer on the middle of the cup. Experiment: • I placed the plastic cup on my kitchen window where direct sunlight and shade is accessible to prevent extreme temperatures. This composting lab.
