Parachute Parade Activity: Skydivers rely on parachutes to slow them down as they jump from airplanes and other high places. Parachutes catch air and create drag, a force that works against gravity. Parachutes are usually large and made of lightweight materials, so they create the most drag possible without adding a lot of weight. Practice your families’ engineering skills and create a parachute that helps a toy reach the ground slowly and safely! You’ll Need: Several items from this list: plastic wrap, tissues, paper towels, plastic bags, tissue paper, coffee filters, handkerchiefs 1 toy minifigure or large paperclip string or thread scissors tape paper and pencil optional: stopwatch Here’s How: 1. Your challenge is to make a parachute for a toy minifigure that descends the slowest using only the materials provided. You can work as a group to make at least two different parachutes, or help each child make their own. Before beginning, brainstorm parachute designs. You can use a computer or smart phone to look up parachute designs, or draw one from memory. 2. Design a test to see which parachute falls the slowest (has the most drag). Predict which parachute will fall most slowly before dropping them. Hold both parachutes from the same height and drop them at the same time. You can use a stop- watch to time their descent. 3. Look at your results. Was your prediction correct? Why did one parachute fall slower than another? 4. Try again. What variables slowed your parachute down? Which ones made it fall faster? Engineers can design the same project many times before they are done. POINTER: This activity is great for practicing engineering by changing variables. A variable is a thing that the may make your parachute behave differently. Some variables to consider are: material choice, parachute size, and length of string. Remember to keep everything the same except the one variable you are testing, so that you can see whether or not your variable affects your project.

  • Parachute ParadeActivity:

    Skydivers rely on parachutes to slow them down as they jump from airplanes and other high places. Parachutes catch air and create drag, a force that works against gravity. Parachutes are usually large and made of lightweight materials, so they create the most drag possible without adding a lot of weight. Practice your families’ engineering skills and create a parachute that helps a toy reach the ground slowly and safely!

    You’ll Need:• Several items from this list: plastic wrap,

    tissues, paper towels, plastic bags, tissue

    paper, coffee filters, handkerchiefs

    • 1 toy minifigure or large paperclip

    • string or thread

    • scissors• tape• paper and pencil

    • optional: stopwatch

    Here’s How:1. Your challenge is to make a parachute for a toy minifigure that descends the slowest using only the materials provided. You can work as a group to make at least two different parachutes, or help each child make their own. Before beginning, brainstorm parachute designs. You can use a computer or smart phone to look up parachute designs, or draw one from memory.

    2. Design a test to see which parachute falls the slowest (has the most drag). Predict which parachute will fall most slowly before dropping them. Hold both parachutes from the same height and drop them at the same time. You can use a stop-watch to time their descent.

    3. Look at your results. Was your prediction correct? Why did one parachute fall slower than another?

    4. Try again. What variables slowed your parachute down? Which ones made it fall faster? Engineers can design the same project many times before they are done.

    POINTER: This activity is great for practicing engineering by changing variables. A variable is a thing that the may make your parachute behave differently. Some variables to consider are: material choice, parachute size, and length of string. Remember to keep everything the same except the one variable you are testing, so that you can see whether or not your variable affects your project.

    Design engineer Rachel Gitajn combines passions for art and physics into a career making the bicycles we all get to enjoy. Creativity drew her to mechanical engineering. In her career, she has used her

    problem solving skills to design snowboards and bicycles. On what she enjoys about her job, Rachel says, “I get to make things that look beautiful, perform, and make people happy.” Find out more about

    Mentor Moment:

  • Desfile de ParacaídasActividad:

    Los paracaidistas dependen de los paracaídas para disminuir la velocidad con la que van cayendo al saltar desde aviones y otros lugares altos. Los paracaídas atrapan el aire y generan resistencia, la fuerza que actúa en contra de la gravedad. Generalmente, los paracaídas son grandes y hechos de materiales ligeros para crear la mayor resistencia posible sin aumentar mucho peso. Mejora las habilidades de ingeniería de tu familia y crea un paracaídas para ayudar a una figurita de juguete llegar al suelo ¡despacio y a salvo!

    Necesitarás:• varios artículos de esta lista: papel para envolver,

    pañuelos faciales de papel, toallas de papel, bolsas

    de plástico, filtros para café, pañuelos

    • 1 figurita de juguete o un clip para papel grande hilo

    o cuerda• tijeras• cinta adhesiva

    • papel y lápiz

    • opcional: cronómetro

    Haz lo siguiente:1. Tu reto es hacer un paracaídas para una figurita de juguete que descienda lo más despacio, usando sólolos materiales proveídos. Puedes trabajar en equipo para hacer por lo menos dos paracaídas diferentes, o puedes ayudar a cada niña a hacer el suyo. Antes de empezar, piensa en diferentes diseños para el paracaídas. Puedes usar la computadora o un celular para buscar diseños de paracaídas, o dibuja uno de memoria.

    2. Diseña una prueba para ver cual paracaídas cae más despacio (genera la más resistencia). Predice cual paracaídas caerá mas despacio antes que lo hagas. Agarra los dos paracaídas desde la misma altura y déjalos caer al mismo tiempo. Puedes usar un cronómetro para tomar el tiempo de descenso.

    IDEA: Esta actividad es genial para practicar la habilidad de cambiar variables. Una variable es una cosa que puede cambiar el comportamiento del paracaídas. Algunas variables a considerar son: el material elegido, el tamaño del paracaídas, la longitud del hilo. Recuerda mantener todo igual, excepto la variable que vas a probar, para que puedas ver si tu variable afecta o no tu proyecto.

    La ingeniera de diseño Rachel Gitajn combina su pasión por el arte y la física en una carrera haciendo bicicletas que todos llegamos a

    disfrutar. La creatividad fue lo que atrajo a Rachel a la ingeniería mecánica. En su carrera, ha usado sus habilidades para resolver

    problemas para diseñar tablas de snowboard y bicicletas. Sobre qué es lo que disfruta de su carrera, Rachel dice, “Tengo la oportunidad de hacer cosas que son bellas, funcionan bien y hacen feliz a la gente.”

    Consejo de un Mentor:

    3. Observa tus resultados. ¿Fue correcta tu predicción? ¿Por qué un paracaídas cayó más despacio que el otro?
