National Arbor Day is Coming… Hug A Tree!

“The cultivation of flowers and trees is the cultivation of the good, the beautiful and the
ennobling in man, and for one, I wish to see this culture become universal.”
Those words, from J. Sterling Morton, the founder of Arbor Day, got me thinking about how caring for trees and respecting all living things greatly impact future generations.
National Arbor Day (held this year on April 27th) is an annual observance celebrating the role of trees in our lives and promoting tree planting and care. This holiday was first observed in 1872, in Nebraska, but tree planting festivals are as old as civilization. Trees have appeared throughout history as the symbol of life and hope.
As teachers, we can encourage students to appreciate trees, nature, and all living things for future generations to enjoy! Here are a few STEAM (Science, Technology, Engineering, Arts, and Math) ideas to help you spread agricultural information and enthusiasm for trees on Arbor Day with your students:
SCIENCE: Explore the different types of trees in your area and make a chart that identifies each tree’s structure, how it benefits society, and how it lives. Plant a new tree, and then learn how it develops and what nutrients it needs to promote healthy growth.
TECHNOLOGY: Investigate online the history of Arbor Day and the importance of trees throughout the world. Explore how counting the rings in a tree trunk can tell you its age. Explore how animals depend on trees (e.g., nests, hives, storing nuts, etc.). Create a class video, blog, or podcast on the importance of trees in our lives.
ENGINEERING: Ask your students: what should we build with wood? Are skyscrapers made out of timber a good use of this natural resource, or are there other aspects of civil and structural engineering or large-scale infrastructure that would be a better use of wood? Conduct a study on this, perhaps using a Design Challenge that tests construction strength and durability under specific constraints and criteria.
ARTS: Collect an assortment of leaves from different trees. Place leaves flat on a table and covers with a sheet of paper. Rub crayons on the paper over the leaves to make the leaf rubbing relief designs. A similar idea is to make bark rubbings from different trees by laying paper over bark and rubbing with crayons. Have students try to identify which rubbings came from which trees. Students could also create and share an original poem, song, or work of art about trees.
MATH: Use trigonometry or estimation techniques to measure a tree’s height and diameter. For young students, count the rings in a tree trunk to tell its age. Look for fractal patterns in the growth of leaves and branches. How does the Fibonacci sequence relate to plant growth?

Science fairs: Nurturing the 21st century thinker

3D Tessellation model A bespectacled 6th grader enthusiastically explains ‘efficiency of 3D space tessellations’ with myriad equations and handmade tessellation patterns to address the needs of the packaging, storing, shipping and construction industry. Another middle school student, was inspired by his little brother’s telescope and built a simple vacuum chamber using a PVC pipe with a microphone and a speaker on both ends to find out how sound travels on Mars! This 8th grader from Granada Islamic School used an oscilloscope his mother found at an auction to measure the sounds. “I poke around and find junk to build my projects. It’s fun.” Science projects today have become fun for many students as they use more hands on activities to experiment and understand concepts. These two middle school students were among 996 participants at the recent Synopsys Silicon Valley Science and Technology Championship , where RAFT was one of the special judges.

Why I Chose a Career in Education

There are many moments where I am reminded why I chose a career in education. These moments arise when I am engaged in conversation with other teachers, conducting professional development workshops, developing new lessons, or simply reading about changes and latest developments in the field. Education is a dynamic field, and it has provided me with many opportunities to positively impact the lives of young learners as well as provide inspiration and support to new teachers. One such occasion occurred in mid-April when I was invited by Dr. Rosalinda Quintanar to conduct a presentation to students in a class entitled Meeting the Needs of Second-Language Learners (EDTE 162), a course within San Jose State University’s Teacher Education Department and a credential requirement. The class consisted of approximately 30 credential candidates, and its primary focus is applying theory and practical classroom techniques for providing equitable access to content for English language learners.

RAFT SAN JOSE CELEBRATES PI (π) DAY – 3.14, WITH A BOATLOAD OF FREE ACTIVITIES!

Come meet RAFT ’s Math Activity Developer, Jeanne Lazzarini, at RAFT San Jose who has a treasure chest of Pi-Day activities to share!  Not only will she be dressed as a Pirate (because Pi rates!), she’ll also offer you delicious pie to eat while showing you great Pi-Day Math activities to make and take, to use in your classroom to celebrate Pi day! The Pi-Day activities include RAFT Math Idea Sheet activities like Finding Pi , Wearable Pi and Pi Day Pin . Irrational number Pi, also written as π, is the ratio of the circumference of a circle to its diameter, and is celebrated all over the world on March 14th because π is a number that begins as 3.14!  With the use of computers, Pi has been calculated trillions of digits past the decimal point! Pi is an irrational and transcendental number, and its digits continue infinitely without any repeating patterns of digits!  Pi has been used in many applications for over 4000 years! π rate activity days at RAFT!
