As the oscillations increased, the tower began to topple over. The pedestal below begins to shake, simulating an earthquake. They are glued to the respective wood panels so that they do not slide off when the base starts to vibrate.Įach team's earthquake-resistant tower rests on a 30cm long wooden plank and increasing weight metal blocks are added on top of the tower. The toothpick towers must be at least 50 cm tall and weigh less than 65 grams. Since 2006, the Faculty of Architecture, Faculty of Engineering, Sojo University has held an annual "Tower Seismic Contest", challenging student teams to build earthquake-resistant towers using only toothpicks and glue. To achieve the goal of finding new creativity, an engineering school created a competition for students to find a toothpick tower design that can withstand earthquakes. A structure that can absorb all the energy from an earthquake, it won't collapse. To withstand the extreme forces of an earthquake, a building must absorb as much seismic energy as possible. Therefore, building earthquake-resistant architecture is important for the country of Japan. About 71% of the world's most powerful earthquakes occur in the Ring of Fire.Īlthough Japan occupies only 0.25% of the Earth's land area, 18.5% of the world's earthquakes occur here, 20% of the magnitude 6.0 earthquakes and above. In its history, the country of the rising sun has experienced hundreds of earthquakes and tsunamis that occurred right next to the Pacific Ocean. Snippets: A Story About Paper Shapes – Snippets is a story that revels the power of kindness and the beauty of being unique.A technical university in Japan is famous for its unique contest to build earthquake-resistant toothpick towers.ĭue to its location in the Pacific Ring of Fire, where there is continuous seismic and volcanic activity, Japan is the most earthquake-prone country in the world and suffers from devastating earthquakes. One by one soon all sixteen shapes are trapped. First the circle, next the triangle and then the square. Tangled – When the neighborhood shapes go climbing on the park jungle gym the last thing they expect is a tangle. Can Walter make a web that is both wonderful and strong? The webs he makes at first are woven in special shapes–a triangle, a square, a circle–but they are still wibbly-wobbly. Walter’s Wonderful Web – A determined little spider named Walter is trying to make a sturdy web that will stand up to the blustery wind. If you have a hard time finding them, you can order them through my Amazon affiliate links by clicking the images below. Most of these books can be found at your local library or used bookstore. Ok, I know you’re excited about this activity so let’s get started!įill your book basket with a great collection of books about shapes. This preschool STEM activity took about 5 minutes to set up, and Grace stayed busy for a good 30 minutes. I was convinced this was going to be Grace’s favorite activity yet and guess what, it was!
We just bought marshmallows, and I had toothpicks in my pantry. It took me a few minutes, but then it came to me! Grace could build 2D shapes out of marshmallows and toothpicks! On the way home from the store I thought about what I could do with the marshmallows. Building Shapes with Marshmallows and Toothpicks She gets her treat and I feel better about giving it to her. Ok……….I’m not one of those Moms that refuses to let her kids have sugar sometimes but I am that Mom who feels the need to combined a once in a while sugary treat and an educational activity. She told me she wanted marshmallows, the little ones. We were in Publix the other day, and I told her she could pick out a treat for being so well behaved at the store. My daughter Grace is totally obsessed with shapes! She points them out everywhere we go and when I ask her what she wants to learn about I’m sure you can guess what her answer is…………. Preschoolers will enjoy building shapes with marshmallows and toothpicks for hands-on math practice. Perfect STEM activity for little ones.
