In this math activity, learners estimate how many pennies are in a jar by predicting and counting handfuls of pennies.

This is a quick activity (on page 2 of the PDF under Stained Glass Activity) about the "Tyndall effect," the scattering of visible light when it hits very small dispersed particles.

In this activity, learners practice counting and multiplication as they figure out how many animal body parts they have to examine as "Dr. Vet."

In this data analysis activity, learners quantify the abundance and distribution of sea scallops in and adjacent to the Mid-Atlantic closed areas.

In this activity, learners investigate the olfactory system by conducting several experiments.

In this activity, learners develop their understanding of combinations as they create as many different kinds of tostadas as possible.

In this math activity, learners play a probability game and try to be the first to get to the end of the game board path .This activity guide contains a material list, black line masters for the game

This lab activity is about toxic substances like pesticides and their effects on biological systems. The activity starts with an introduction of how birds sequester calcium to make an egg.

In this seismic simulation, learners play a "who-dunnit" game to explore earthquakes.

In this health activity, learners explore breathing, lungs and asthma. Learners test their lung capacity by blowing air into balloons.

In this activity, learners "dance" (move back and forth at varying speeds) by reading a graph. This is a kinesthetic way to help learners interpret and understand how motion is graphed.

In this oceanography and data collection activity, learners cast real time sea state conditions using buoys from NOAA's National Data Buoy Center.

This event guide features three related explorations in which learners investigate the following science concepts: how you design and build a structure helps determine how strong it will be; different

In this activity, learners use simple items to construct a device for indicating air pressure changes.

This activity (located on page 2 of PDF) introduces learners to the real size of animals using nonstandard measurement.

In this activity, learners cut a shape into two equal sized pieces and use their knowledge of geometry and space to prove that the two parts are equal.

In this math activity, learners create symmetrical designs for paper models of special blouses known as huipiles.

In this activity, learners explore the relative sizes and distances of objects in the solar system.

In this three-day lesson, learners identify two-dimensional shapes used in castle construction, create a castle collage using assorted shapes, and design tapestries using repeated patterns of color, s

In this math activity, learners play a game that helps reinforce learners' understanding of the coordinate system.
