Materials: * Heavy duty zip-lock baggie * 1 strawberry (fresh or frozen and thawed) * Cheesecloth * Funnel * 100 ml beaker * Test Tube * Wooden coffee stirrer * DNA extraction buffer * Ice-cold 95% isopropyl alcohol Hypothesis: DNA can be extracted if you use certain buffers. Procedure: 1. Place one strawberry in a zip lock baggie and carefully press out all of the air and seal the bag.
Use your 4 markers to draw a different colored dot on each of the pencil marks on the paper strip. Allow the markers ink to dry, and then go back recolor each dot. 5. Prepare the saltwater mixture by mixing 1/8 teaspoon of salt and three cups of water in a clean 2-liter bottle. Stir or shake the solution until it is dissolved.
The peas are ready for harvest in 80 to 90 days after planting. The best time to plant black-eyed peas is after the soil temperatures have reached 65 degrees or more. Fava beans are also referred to as horse beans, broad beans and English beans. Though a fava bean is a legume, it is more closely related to the pea family, than to a garden bean or legume. Fava beans grow best in areas with long, cool summers and do not like very high summer temperatures.
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.
Plant Growth Investigation The scientific method is a way to ask and answer scientific questions by making observations and doing experiments. The question I was attempting to answer was; what are the effects of different types of water on the growth of grass? My hypothesis was if we water the grass seeds with bottled, tap, and salt water, then the seeds getting the bottled water will grow the best and be the tallest at the end of the experiment because the bottled water doesn’t have the toxins that the salt and tap water will have. We needed a lot of materials to conduct our experiment they were; • 6 Seven ounce cups • Soil • Seeds (20 per cup) • The 3 types of water (Salt, Bottled, Tap) • Graduated Cylinder • Ruler • Pencils • Sharpie • Our chart/packet Our procedure was to first gather all of the materials we needed. We first labeled each cup with what type of water we were going to use.
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.
5. Put funnels with coffee filters inside wooden block on ring stand 20 cm off table. 6. Place one ounce of applesauce into each filter using a spoon. 7.
Purpose The purpose of this experiment is to see the effect that paper chromatography has on ink. 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. Coffee filters usually are round, but it's easier to compare your results if the paper is rectangle. So, your first task is to cut the coffee filter into a rectangle measuring three cm by nine cm. You will need two of these strips to complete the lab.
The cap of a centrifuge tube was used to collect approximately one (1) gram of soil from the sample. This was then added to a bottle containing 99ml of sterile water for a 10-2 dilution, 1ml of 10-2 dilution was then added to a bottle containing 99ml of water for a 10-4 dilution. 1ml from the 10-4 dilution was then added to 99ml of water for a final dilution of 10-6. 1ul of each was plated on different starch agar plates with the aid of a micropipette and a plate spreader. The plates were then incubated for a week.
Iowa grows the most corn of all 12 states. They grow the majority of corn produced in the States. 8) Corn is used for a variety of non-food sources form adhesives to explosives. It is also used in plastic and has a total of about 400 non-food uses. 9) Corn as we know it was not found in nature, but was developed over
