This week in the after school Science Club, we started a new unit on balance and stability. We will look at buildings, bridges, roads, pyramids, anthills, beehives and many other “constructions” to hopefully better understand how things go together. We began this week using grapes and toothpicks to determine what structural form is the most stable. In the end, we ascertained that the triangle is the steadiest shape and we began to talk about how triangles can be used in two and three dimensions. We tried to build a geodesic dome but the grapes would not co-operate. No matter, getting there was most of the fun and as you can see from these photographs, a group of children aged 4-7 years can be kept perfectly happy with a pile of grapes, some toothpicks and the freedom to talk about what they are making for nearly an hour.
