#### Mass of the Earth

The ExploratoriumAdd to list DetailsIn this activity, learners use basic measurements of the Earth and pieces of rock and iron to estimate the mass of the Earth. Learners will calculate mass, volume, and density, convert units, and...

#### Polynomial and Rational Functions: Building Boxes

PBSAdd to list DetailsIn this math lesson, learners explore polynomial and rational function patterns. Learners investigate the relationships between the x-intercepts, factors, and roots of polynomial functions using a...

#### Getting There!: Navigation and Trajectory

NASAAdd to list DetailsIn this two-part activity, learners map a navigation plan to get from Earth to Mars and back. In activity one, learners represent the orbital paths of Earth through dance and dramatic movement. In...

#### How Big is Small

The ExploratoriumAdd to list DetailsIn this classic hands-on activity, learners estimate the length of a molecule by floating a fatty acid (oleic acid) on water. This lab asks learners to record measurements and make calculations...

#### Multi-Variable Relations: Stressed to the Breaking Point

PBSAdd to list DetailsIn this math lesson, learners explore the relationship between the thickness of a spaghetti bridge, the length of the bridge, and the amount of weight that can be supported by the bridge. Learners...

#### Linear Functions: Mystery Liquids

PBSAdd to list DetailsIn this math lesson, learners analyze the density of liquids in order to explore linear functions. Learners gather mass and volume data for two mystery liquids, oil and water, and then use the data...

#### Quadratic Functions: Toothpicks and Transformations

PBSAdd to list DetailsIn this math lesson, learners explore transformations and quadratic functions through toothpick patterns. Learners examine the mathematical pattern that emerges as they build a geometric design...

#### Rates of Change: Bottles and Divers

PBSAdd to list DetailsIn this math lesson (page 2 of the PDF), learners use bottles of various shapes to explore the abstract concept of rate of change. Learners use a graduated cylinder to measure amounts of water,...

#### Atmosphere Composition Model

The ExploratoriumAdd to list DetailsIn this activity, learners create a model using metric measuring tapes and atmosphere composition data. Learners will investigate the major components of the atmosphere (nitrogen and oxygen) as...

#### Transit Tracks

NASAAdd to list DetailsIn this space science activity, learners explore transits and the conditions when a transit may be seen. Learners use models to investigate how a planet's size and distance from its star...
