The Beaks of the Finches
Source Institutions
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.

Prepare for a Dock Shop Field Trip
Source Institutions
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.

Disappearing Crystals
Source Institutions
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.

Spots, Lines and Lasers
Source Institutions
Learners shine the light of a laser pointer through sheets of fabric that all have a different number of threads per inch.

Shake It Up!
Source Institutions
Learners drop a magnet through a coil of wire to create electric current in a circuit. LEDs in the circuit allow learners to detect the direction of current flow.

Statistics: Button, Button
Source Institutions
In this math activity, learners read "The Button Box" by Margarette S. Reid and then make their own button boxes filled with different buttons.

Healthy Choices: A Family A-Fair
Source Institutions
Learners and their families celebrate and recognize the importance of making healthy choices every day by participating in a health fair.

A Matter of Splatter
Source Institutions
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.

Mix It Up
Source Institutions
In this math lesson, learners are introduced to proportional reasoning through modeling, sharing, and questioning techniques.

How Thick is Your Hair?
Source Institutions
In this activity on page 13 of the PDF, learners use a laser pointer (with known wavelength of light) to measure the thickness of a human hair.

Join the Dinosaur Age
Source Institutions
In this activity, learners rotate through several learning and play stations to explore dinosaurs and paleontologists.

What is a Fossil?
Source Institutions
In this activity about dinosaurs, learners explore how and why fossils form. First, learners are introduced to dinosaur fossils by reading the book "Bones, Bones, Dinosaur Bones" by Byron Barton.

Boats Afloat
Source Institutions
In this water activity, learners build boats that float and sink. First, learners listen to the book, "Who Sank the Boat" and practice making predictions throughout the story.

Tree-mendous Plots
Source Institutions
In this math lesson, learners record and graph plant growth and interpret data. Learners plant seeds, and once the seeds sprout, record the change in height of the plants for several days.

Castles Inside and Out
Source Institutions
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

Construction and Destruction
Source Institutions
In this three/four-day lesson, learners calculate perimeters and areas and draw the castle plan to scale.

Hungry as a Caterpillar
Source Institutions
In this indoor and outdoor activity, learners discover that insects grow and develop as do all living things, going through a process known as complete metamorphosis.

Zoo Calendar
Source Institutions
Use the Zoo Calendar (page 1 of PDF) to involve learners in interdisciplinary, whole language, and writing activities about ecological concepts.

Cloud Fun
Source Institutions
Learners complete a series of hands-on and investigative activities to explore cumulus clouds.

Give or Take?
Source Institutions
In this outdoor activity, learners work in pairs using their senses—especially touch—to learn more about individual trees.
