This activity helps the learner answer the question: "What environmental problems arise due to animal and human overpopulation and what might need to be done to combat these problems?" Learners play a

In this two-part activity, learners explore the Earth and Sun's positions in relation to the constellations of the ecliptic with a small model.

Exponga estos pósteres en el salón o déjelos donde los chicos los puedan explorar. Los chicos buscan las respuestas en libros de consulta, explorando el salón, y usando su creatividad.

In this activity, learners explore why animals, specifically dinosaurs, live in families.

Learners examine the properties of light by experimenting with an LED-flashlight and polarizing filters. When two polarizers are used, they block all light when they are placed at right angles.

In this simulation, learners become birds different beak types. Learners use various tools to represent beaks to pick up seeds and place them in a petri dish.

In this story time program, young learners listen to the Dr.

Learners drop two different masses of play dough and observe how long it takes them to hit the ground.

In this activity (located on page 9 of the PDF), learners are introduced to Aesop's fable, "The Crow and the Pitcher." In the story, a clever crow drops pebbles into a pitcher to cause the water level

These math posters have questions written on them, such as: How many colors can you name in a minute? or How many seconds can you balance on one foot?

In this activity, learners construct a projector out of cardboard to view their favorite images (such as storybook illustrations) on the wall.

Learners observe projectile motion by launching wooden balls off of a table top. They set up a rubber-band launcher so that each ball experiences a consistent amount of force.

In this activity, learners explore what makes a boat float and sink. They examine and test various objects to determine why objects float or sink.

Learners experiment with water gel crystals, or sodium polyacrylate crystals, which absorb hundreds of times their weight in water. When in pure water, the water gel crystals cannot be seen.

In this activity, learners participate in a simulated dig to discover fossilized dinosaur bones. Learners take notes, make a map and propose theories about dinosaurs.

In this activity, learners explore the size and scale of dinosaurs. Learners listen to "Dinosaurs, Dinosaurs" by Byron Barton to understand some background information about dinosaurs.

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.

Learners build a pendulum from a yo-yo, and then design their own experiment to determine what affects the pendulum's period of swing.

In this math lesson, learners explore probability.

In this math-based activity, learners will experiment to find how height and angle affect spatter and then use this knowledge to solve a crime.
