This lesson focuses on how to measure at the nanoscale and provides learners with an understanding how small a nanometer really is.

In this activity, learners explore dinosaur fossils and skeletons. First, learners listen to "Tyrannosaurus Rex" by Daniel Cohen to learn about T. rex dinosaurs specifically.

In this activity, learners are introduced to tree rings by examining a cross section of a tree, also known as a “tree cookie.” They discover how tree age can be determined by studying the rings and ho

In this math lesson, learners explore linear patterns, write a pattern in symbolic form, and solve linear equations using algebra tiles, symbolic manipulation, and a graphing calculator.

In this design and physics challenge, learners construct a cylindrical wing, fly it, make modifications, and determine how the changes affect flight patterns.

In this activity about cartography, learners work in teams to create two different map projections: a planar (or polar) and a cylindrical (or Mercator) projection.

This is a classic exercise for visualizing the scale of the Solar System.

In this activity (page 95 of the PDF), learners create Escher Staircase models similar to those that were used by Neurolab's Spatial Orientation Team to investigate the processing of information about

In this activity (on pages 55-66 of PDF), learners fold paper into origami shapes and then combine several identical shapes into a three-dimensional structure.

In this lesson, learners cut paper into very small pieces to explore the small size of quarks, the smallest thing we know of on Earth.

In this activity, learners explore dinosaur skeletons.

In this activity, learners explore the size and scale of dinosaurs. Learners listen to "The Littlest Dinosaurs" by Bernard Most to learn about the different sizes of dinosaurs.

In this math lesson, learners predict, interpret, and sketch graphs of functions related to the shapes of bottles. A measure of water is poured into a container.

In this activity, learners investigate how geometry plays a role in perspective.

In this math lesson (page 2 of the PDF), learners use bottles of various shapes to explore the abstract concept of rate of change.

Learners create a tool to measure how well they grip a wet object when their fingers are smooth versus wrinkly. Are smooth or wrinkly fingers better at holding on to the object?

In this activity, learners will explore how a hydrometer works by building a working model and conducting experiments.

Build a house you can fit inside, using cardboard tubes.

In this activity, learners explore what is and is not active play and how it contributes to a healthy body and mind. Making active play a routine part of every day is a key concept of the experience.

In this math lesson, learners design an experiment to model a leaky faucet and determine the amount of water wasted due to the leak.
