<p> Using Basic Lab Equipment</p><p>DIRECTIONS: Read each directive carefully before you begin on the task. Talk over the task with your lab partners to determine the best method. Remember to use each piece of lab equipment safely and carefully. Record your responses (findings from your tasks) on the lines provided.</p><p>MATERIALS PROVIDED: beaker, dropper, metric ruler, tweezers, corn kernels, water supply, graduated cylinder, spoon, goggles (1 per students), waste container, balance, juice can lid, funnel, three washers **NOTE: Before you begin the tasks, obtain 600 mL of water in the larger waste container. You will use this water for the liquid tasks.</p><p>I. PRACTICE WITH LIQUID MEASUREMENT</p><p>TASK RESULTS 1. Starting with an empty beaker, transfer water into the beaker by using the spoon until the beaker holds exactly 30 mL of liquid. Count the number of spoonfuls it takes to complete this task. 1. ______</p><p>2. Starting with an empty graduated cylinder, transfer water into it using a dropper until the level of the water is at the 12 mL marking. Count the number of drops it takes to reach that level. 2. ______</p><p>3. Fill the graduated cylinder to 25 mL and empty the contents into the beaker even with the 50 mL marking. Tell how many full cylinders you needed. 3. ______</p><p>II. PRACTICE WITH MEASURING MASS</p><p>4. Find the mass in grams of three washers 4. ______</p><p>5.
