Abstract:
This series contains grade specific STEM (Science Technology Engineering Math) activities for elementary teachers in the Virgin Islands Department of Education (VIDE). Each worksheet contains the VIDE Science Content Standards and the Common Core State Standards in Math and English Language Arts that are practiced by completing each activity. The materials list and procedures are meant to be supplemented with handouts and supplies from the NASA Educational Resource Center at the St. Croix Curriculum Center and requests for implementation assistance are expected. The series is made possible through VIDE Division of Curriculum and Instruction directed by Ms. Cheryl Willocks.

Grades 2 6 The simple definition is to plan and construct something for a purpose. Students will see short videoclip (3 minutes) of a robotic arm in space ://www.nasa.gov/mov/329198main_Robotic_Arm.mov Materials are provided by NASA Education Specialist. The following second grade standards are addressed: Reading L1.SPL.2 The learner will be able to a pply phonemic awareness to spel l (Example: Fancy word for robotic arm is end effector) SL.2.1a Follow agreed upon rules for discussions (e.g., gaining the floor in respectful ways, listening to others with care, speaking one at a time about the topics and texts under discussion). SL.2.1b. Build on others talk in conversations by linking their comments to the remarks of others. SL2.1c Ask for clarification and further explanation as needed about the topics and text under discussion. Math CCM 2.MD.2 Measure the length of an object twice, using length units of different lengths for the two measurements; describe how the two measurements relate to the size of the uni t chosen (Example: Measure the strings in inches and centimeters and explain why the centimeter measurement is a bigger number than the inches measurement) CCM 2.MD.10 Dr aw a picture graph and a bar graph (with single unit scale) to represent a data set with up to four categories. Solve simple put together, take apart, and compare problems4 using information presented in a bar graph. (Example: pick up 4 different objects with the robotic arm and make a bar graph showing the mass of each object) SMP3 Construct viable arguments and critique the reasoning of others. (Example: During the conclusion phase of the activity, explain the causes of the limitations on the total amount of weight that can be lifted SMP6 Attend to precision. (Practiced throughout completing the hands on procedures)

(Example: in this activity, using a ruler) S2.REI.1 The learner will be able to develop a problem and solve it individually or in groups doing different things that contribute to the results. ( Example: trial and error to build the device to grab and hold larger masses shapes, etc.) Materials needed Styrofoam coffee cups (2 each) String Cellophane tape Scissors Plastic picnic knives (serrated) 12 oz plastic bottles Water Balance Graph paper Pencil Procedure: 1. Nest the two cups together and cut through both cups where indicated in the diagram by the dashed line. Smooth the cut edges by scraping them with the picnic knife edge. 2. Cut three pieces of string 12 centimeters long each. 3. Tape the end of the first string to the inside of the inner coffee cup just below the cut edge. Tape the other end of the string to the outside of the cup but do not press this piece of tape tightly yet. 4. Repeat step 3 twice more, but place the strings about 1/3 of the way (120 degrees) around the cup from the first string. 5. W hile holding the rim of the inner cup, rotate the outer cup until the three strings cross each other. The strings will have some slack. Pull the end of the strings on the outside until they are straight and intersect exactly in the middle of the opening. P ress the tape on the outside to hold the strings.

Use the robotic arm end effector to pick up an object such as a pencil. Have someone hold a pencil upright. Open your end effector so that the strings are not crossing each other. Slip the end effecto r over the pencil s o that the pencil extends down the center and not through any of the loops. Rotate the outer cup until the strings grasp the pencil. Pick up the pencil. 2. You may find that the pencil is too slippery to be held securely. How might you modify the pencil so that it can be held? Design a standard grapple fixture that can be mounted to other objects so that they can be picked up. Assessment: Review the tables or charts created by your students. Pay special attention to the ideas students h ave for improving their grapple fixtures. Assessment worksheet Engineering Worksheet 1. What two types of units are found on your ruler? 2. Find the centimeter side, how many total are there? How many inches does that equal? 3. How could you increase the amount of weight that your robot hand can hold? 4. What types of materials cannot be picked up by this type of hand? 5. Use the graph space below to show the mass of each object lifted. 6. How could you change the object being lifted to make it easier to grasp?
