![]() Have students try out the catapult using the pom-pom by placing it in the cup and then flinging it. Students will attach the small cup to the top of the last stick.You can use Legos to make just about anything, including building a catapult. LEGO Catapult Our kids love Legos, and it’s one of our favorite STEM toys. However, inform students to not secure this one too tight. The students have to hit a target with a ping pong ball that is launched from their catapult at distances of 10 and. If you want to make a pencil catapult, you could use a similar design and structure with a few pencils on the base and one for the catapult arm. To serve as the arm of the catapult, students will put a singular popsicle stick vertically, attaching it, again, with a rubber band.When students have attached the non-eraser ends together, explain to them that now they will place one more popsicle stick on the other end, securing this with rubber bands.Then, they will attach the non-eraser ends of the pencils to each other with a rubber band.Using more rubber bands, students will attach these two perpendicular pencil constructions to each other.This will be perpendicular to the first one, too. Once students have done so, they will secure one more popsicle stick to the pencil.Instructions Put your catapult in an open area with a sturdy, flat surface such as a table or an open space on a hard floor. Next, students will do the same to the second pencil. Put your catapult on its base, locate the end of the launching stick that sticks up and glue the bottle cap there so it forms a small cup to hold the cotton ball.This will help serve as a demonstration and diffuse any confusion.*** ***NOTE: Mentors, do the activity in the front of the class with the students. ![]() For example, which of the projectile (pom poms or pencil erasers) will travel farther How far do you. After passing out the materials, tell students that they should can attach a popsicle stick to a pencil using a rubber band – these pieces should be perpendicular. Predict what you think will happen in this experiment.Begin the lesson by telling students that they get to make their very own catapult!.Materials: 5 Popsicle sticks, 8 rubber bands, 1 small cup, 1 pom-pom, & 2 pencils ![]()
