This allows the Catapult to engage children in learning by doing in collaboration with the STEM Ambassador Network and local primary schools. create the catapult Step 4: Test (Duration of 5 minutes ) Questions To check if the catapult works, we should test if the ping pong ball reaches a distance of 3ft when launched (Learning outcome 5) Mission Have the students test their catapult designs at the hallway by Answer: The golf ball, because it is heavier. Fills out some of the worksheet. Two important equations exist for position in projectile motion with no friction. Ball Roll: Have the children try to roll the balls into the hole in the middle of the parachute. Does not fill out worksheet. Who has heard of catapults? This means the projectile will go faster and farther. Have the students engage in a discussion on how to adjust the catapult to vary the distance to which it can throw a projectile (refer to Activity Sheet 1: Catapult Variables for the list of adjustments which will provide variables to catapult performance). Since there is no air on the moon, there would be no air friction for either the whiffle or ping-pong balls. Describe how force affects the motion of a projectile. The onager (or gone, mangonel, or nag) was typically a single spar held in a more or less vertical position by a torsion device rotating around a horizontal axis. Programs for Teachers WP Cumulus Flash tag cloud by Roy Tanck requires Flash Player 9 or better. to vary arm length), 2 Pegboard Sides (measurements: Base 12 in. Let's say we want our catapults to launch Ping-Pong balls at a certain target. Public Policy This device used gravity instead of torsion springs to provide propulsion energy. For example, in the associated activity, accuracy is the ability to hit the target with the Ping-Pong ball. accuracy : The degree of closeness of a measured or calculated quantity to its actual (true) value. Release the string to launch the catapult. You guessed it â we are ready to design, build and test our own catapults! Aerospace If one were to use a golf ball instead of a whiffle ball, would the ball go farther, everything else being equal? Support an argument with evidence, data, or a model. Encourage students to identify parts while they are trying the model. Catapult Presentation Notes Answers (doc), Engineering Fun! Catapult Presentation Notes Answers (pdf), Engineering Fun! Well, we are about to do a really fun activity. If there is no air resistance, how high will the ball rise? To borrow a kit, please apply online. A grant of £5,211 from the Royal Academy of Engineering Ingenious Awards has allowed the Catapult to purchase a series of educational kits to deliver “STEM by stealth” lesson plans. The theory is simple: put a large weight at the short end of a lever arm and put the projectile in some kind of basket at the other end of the lever. Distribute whiffle balls to each student. During the next class period, discuss the challenge questions and clear up any misunderstandings the students may have about the concepts they learned. Catapult Presentation (pdf), Engineering Fun! One concept is force. Catapult Post-Lseson Quiz: At lesson end, have students complete the Catapult Quiz again to assess what they learned. The ball begins to fall when it leaves the cup and it falls exactly the same as if it were not moving. Tape tubes to the floor. The modern catapult is used to launch aircraft from the deck of an aircraft carrier. It would not reach as high a velocity as the other lighter balls and hence wouldn’t go as far. These days, catapults are used for a variety of reasons, from toys to even launching planes and jets from aircraft carriers that have limited runway space! quadrilateral: A polygon with four sides. Catapults Lesson Cierra Pettit. ... Students experiment with distance and accuracy as they make modifications... Get Free Access See Review. In the top left picture, none of the shots are very close to the bull's-eye or to each other. Accuracy describes the nearness of a measurement to the standard or true value. Answer: 45 degrees.

If using the lesson plan with younger kids, be sure to explain how a catapult functions and experiment with potential designs together before inviting the kids to engineer a catapult independently. 2. Make sure no students are in the catapult’s trajectory before triggering it. What do they consist of? 3= meets expectations occasionally Explain (Time: 10 mins) Discuss with students what did and did not work, have them explain why certain settings worked better than others. 6. The entire series will lead students through the design of a miniature catapult using engineering design practices, including: investigating This horizontal motion is uniform and constant according to Galileo's principle of inertia. ... How to make a Catapult Simple and Basic - Duration: 2:20. Does little to complete the procedure. Use 2 rubber bands at the front of the catapult, then firmly attach the string to the chain, and slip the string through the gate hook. Building a catapult with our kids would starts out as a craft and ends with an energetic fun activity. Catapult Presentation Notes (doc), Engineering Fun! Alignment agreement: H = (1/2) x (45^2)/32.2 = 31 feet, 10. Galileo was the first person to accurately describe projectile motion by analyzing the horizontal and vertical components separately. / H .75 in. Pull the string taut to create the tension. Research on Learning When all arrows are grouped tightly together, the cluster is considered precise since they all struck close to the same spot. The closer a system's measurements to the accepted value, the more accurate the system. Chemical You will need to prepare either a class set or a single demonstration catapult in order to teach this powerful lesson on kinetic and potential energy. Lesson Plans They learn how Newton's second law of motion works by seeing directly that F = ma. forces that result in changes in motion, Standard 7 – Interdisciplinary Problem Solving. Have students align the sides with the base and screw in the dry wall screws to secure it. Discuss the adjustments and how they would affect performance. Achievement begins with LessonHub. Do you agree with this alignment? Works very well with partner. Secure this with a nut, making sure to leave it just loose enough for the arm to swing freely. The goal of these lessons is to integrate mathematics, medieval history (specifically knights and Tables: great folding picnic table bench for outdoor eating. (Answer: It will go higher, but not cover as much horizontal distance.) 8. Slide 2: To make a projectile cover the most horizontal distance possible, it should be launched from a 45º angle. Join ends of tubing with a 1⁄4 wood dowel as a plug. Precision relates to whether or not the arrows hit the target in the same place. Explain how teams should take data on their own performance (See Assessment, below) and let the competition begin! Target: A target may be constructed as follows: Bulls Eye — use a pie tin taped down. In this catapult lesson students complete several worksheets and build a catapult while working in groups. Hole Punch Names- Each student will be able to recognize their own name. Build Catapult Model C4 and try it out. The ballista was about 10 times larger than a catapult and threw large stones.

Does not participate in brainstorm. catapult: A toy/machine that launches a projectile. 7. Web Resources Robotics (Optional: show the attached Engineering Fun! The ballista’s design consists of two pieces of wood, each fastened at one end to a torsion device rotating about a more or less horizontal axis. Is not clear in explanation of findings. Teacher Resources Discuss physics terminology. Buckets as bullseyes can also make a nice target. Precision is the degree to which several measurements provide answers very close to each other. Place the whiffle balls inside the cup. (Answer: More force. 1. Environmental Engineering Especially with respect to the past and how it shaped the future. Computer Name the various forms of energy involved in the catapult. How do you think force affects the speed of the Ping-Pong ball and the distance it travels? – ¼ x 20 x 4¼” (nuts – ¼ x 20), Wooden Base (measurements: Base – L 16 in. Answer: Specific pattern. Engineering Design Process To make a projectile cover the most horizontal distance possible, it must be launched from a 45º angle. Catapult Presentation Notes while going through the slides.). Following the lesson, challenge students to complete the associated activity Right on Target: Catapult Game to build accurate and precise catapults using simple materials. Make sure it is below and closer to the rear compared to the fulcrum. 8. Resources for Teachers The same goes for stretching a spring; when released, it will collapse back to its original configuration. One Sentence Summary - At the end of each benchmark lesson, the students will provide the teacher with a one sentence summary of what they learned that day. Cause and effect relationships are routinely identified and used to explain change. Answer: No, the friction would be much greater at the higher speed and the distance would be less than two times. Answer: The ball will act like a falling body with an initial velocity V. The equation for a falling body is as follows: Where H is the height in feet. Click here! Answer: No: The horizontal velocity has nothing to do with the time the ball stays in the air. Environmental Explain and compare the meanings of accuracy and precision. If the same projectile is launched from an angle less than 45º, where will it go? Example: Assume the velocity is 90 ft/sec and the angle with the horizontal is 340 degrees, what is the height? This Catapult Lesson Plan is suitable for 4th - 9th Grade. The catapult started out as a large cross bow to shoot oversized arrows at an enemy. Distribute Activity Sheet 5: Catapult Science Challenge Questions as a homework assignment to each student. Install cup on the lever arm(used to hold the whiffle ball), attaching it with strong packaging tape. Biomedical Originally catapults were designed for use during battles or wars. This lesson plan is designed for kids in 3rd-5th grades although it can be explored with younger children. Physical Science, Science and Technology. Summer Programs (Students) How far would the ball go with no air friction in question 9? Vv = 90 x sin(340), Vv = 90 x .5 = 45 ft/sec Women in Engineering. Provides an in-depth explanation of findings, making good use of vocabulary terms. Caution: The length of chain with the gate-hook and attached string which acts as a trigger device should always be mounted on the catapult base, with the separate gate-hook eye ONLY being mounted on the catapult arm as shown above. Aerospace If a projectile is launched from an angle greater than 45º, where will it go? Shows no understanding of catapult physics. Today we are going to learn all about catapults and the important math and science concepts behind them. Catapult Presentation. Has trouble working with partner. 3. Technology for Learning diy cheap small house plans prices King'S Fine Woodworking Inc. Range — Distance for which a projectile can be thrown. Loading... Unsubscribe from Cierra Pettit? (Lesson Courtesy the Cornell Center for Materials Research (CCMR). Level: Grades 5-12. i.e., most hands-on activities are part of lessons, lessons are grouped into multiday He was able to show that a projectile is controlled by two independent motions that work together to create a precise mathematical curve. If you did a large number of shots in exactly the same way, you would find a specific pattern where the majority of the hits are close together and the others scattered about in a “Normal Distribution.” The way the distribution is spread depends on the various parameters of the catapult and how well they can be repeated each time. The Figure 2 diagram is helpful to review with students the concepts of accuracy and precision. Engineers must master the science and math concepts behind a given technology before they can successfully design and build products that meet their clients' needs. Activity: Building a Catapult In this activity, youth learn how to design and build a catapult that uses a pivot arm (lever) and a fulcrum to launch a Ping-Pong ball across the room. Fills out worksheet clearly. With this science project, you will try your hand at catapult technology. People were placed in a seat at the long end and successively ducked into a pool of water. Inform students that there will be a competition to test their catapult’s accuracy at hitting targets at various distances. The first two types of throwing machines were the catapult and the ballista. In the top right picture, the shots are closer to the bull's-eye, which means the accuracy is getting better, but they are not close to each other (meaning they are not precise). Since both H and T are unknown, we need a second equation. through this catapult STEM challenge, students will learn, build, test, and apply their knowledge.
