Pea Brain!: Explorations in Estimation
University of KansasAdd to list DetailsIn this activity, learners use two different techniques to estimate how many little things fit into one bigger thing. Learners estimate the number of peas that will fit into something the size of a...
Sizing Up the Universe
Smithsonian Center for Education and Museum StudiesAdd to list DetailsIn this online interactive challenge, learners choose items to represent the Earth or solar system, then determine other items to represent the Moon, or Milky Way based on their relative size. The...
Earth Walk
The ExploratoriumAdd to list DetailsIn this hands-on and feet-on excursion, learners take a science walk to visualize the planet's immense size and numerous structures, without the usual scale and ratio dimensions found in most...
Smaller Than You Think
American Museum of Natural HistoryAdd to list DetailsLearners compare a life-size drawing of a Tyrannosaurus rex head and a full-size Sinornithosaurus body to understand that dinosaurs varied in size. Learners trace individual pieces of a dinosaur on...
Cylinders and Scale
The ExploratoriumAdd to list DetailsIn this activity, learners investigate the relative growth of lengths, areas, and volumes as cylinders are scaled up. Learners connect their experience with cylinders to the world outside the...
Scaling Cubes
The ExploratoriumAdd to list DetailsIn this activity, learners explore scale by using building cubes to see how changing the length, width, and height of a three-dimensional object affects its surface area and its volume. Learners...
Colors of Stars
The University of Texas McDonald ObservatoryAdd to list DetailsIn this activity, learners observe colors in the flame of a burning candle to explore connections between matter, light, color and temperature -- basic concepts of matter and energy. Then, learners...
Cutting it Down to Nano
NISE NetworkAdd to list DetailsThis simple activity uses paper and scissors to convey two key concepts to learners: the nanoscale is very small and working on the nanoscale requires special tools. Learners are challenged to cut...
Exploring Size: Scented Solutions
NISE NetworkAdd to list DetailsThis is an activity in which learners will find that they can detect differences in concentration better with their nose (smelling) than with their eyes (seeing). Our sense of smell allows us to...
Solar System in My Neighborhood
Lunar and Planetary InstituteAdd to list DetailsIn this activity, learners shrink the scale of the vast solar system to the size of their neighborhood. Learners are challenged to consider not only the traditional "planets," but also...
