Design Challenge: Craft Stick Trebuchet

There are so many fun things you can do with craft sticks, and giving your kids design challenges and a stack of sticks and other supplies is a great way to get them thinking, engineering and making hypotheses.

I love this idea for constructing a craft stick trebuchet from Frugal Fun for Boys and Girls. She gives the step by step for how to make it, and offers lots of ideas for how to make it into an engineering challenge, such as using balls of different weights, using a longer or shorter arm on the trebuchet and launching your projectile from different places on the arm.

Check her site for printable observation logs as well. This looks like so much fun!

Have you ever made one? I’d love to hear about it.

If you want to teach kids the basics of Hanukkah in the classroom or at home, the picture book Hanukkah by Lesléa Newman and illustrated by Rotem Teplow is a nice place to start.

The book explores the Jewish holiday through the eyes of Lior, a boy whose name means “my light” in Hebrew, which is appropriate for talking about the Festival of Lights.

The book goes through all the preparations the family does, including cleaning, setting the table and cleaning the menorah. It talks about what the menorah symbolizes and the Hanukkah story of the oil in the Holy Temple of Jerusalem lasting for eight days when it should have only been a one-day supply.

The meaning of the letters on the dreidel are also explored, in that when you are in Israel they have a different fourth word (the letters symbolize the Hebrew letters for “a great miracle happened there” or, in Israel, “a great miracle happened here”).

Because the story of Hanukkah involves oil, a lot of the foods that are eaten during the celebration are fried in oil, such as latkes (potato pancakes) and sufganiyot (fried jelly doughnuts). Other foods mentioned include challah, noodle kugel and sour cream and applesauce, which are served with the latkes. Family and friends drop by to share their food, light their menorahs together and play dreidel (the game is explained in the story). It also talks about how the candles are lit through the eight days and what happens at the end of Hanukkah.

The book includes Hanukkah blessings in English and Hebrew and talks about the lunar cycle of the Hebrew calendar, which is why Hanukkah is sometimes celebrated in November and sometimes in December. It also talks about why Jewish holidays are celebrated beginning at sunset rather than in the morning.

Other topics covered include Hanukkah greetings; how to spell Hanukkah; how to make an edible menorah and an tzedakah box (to collect money for charity); recipes for latkes and applesauce; and a more detailed story of Hanukkah than is included within the story of the book. There’s also a quiz to see how well you were paying attention.

This sweet little book is a quick read and a cute overview of the basics of Hanukkah and what the symbols, foods and games mean. It’s a great book for classrooms or at home for sharing basic knowledge.

About the book: 48 pages, hardcover. Published 2024 by words & pictures, suggested retail price $14.99.
