In this activity (located on page 4 of PDF), learners gain insight into the actual size of dinosaurs and practice making estimations and measurements.

Dinosaur Names: Common and Science Names
Source Institutions
In this activity, learners explore how dinosaurs are named and what their names mean. Learners listen to "The Littlest Dinosaurs" by Bernard Most.

Supporting Structures
Source Institutions
In this activity about living things and gravity (page 5 of PDF), learners design and build an exoskeleton or an endoskeleton for an animal of their own invention.

Destination Tidepool
Source Institutions
In this activity (page 7 of pdf), learners research tide pool ecosystems, and then create brochures that "advertise" these environments.

Elephant Foot
Source Institutions
Using a real-size sketch of a baby elephant's footprint, learners estimate, measure and record the width (diameter) and outside edge length (perimeter or circumference) of the footprint.

Food Webs
Source Institutions
In this activity, learners construct possible food webs for six different ecosystems as they learn about the roles of different kinds of living organisms.

Echolocation in Action!
In this activity, learners simulate whale echolocation. Learners experience echolocation by wearing blindfolds, while another learner makes snapping noises in front of, behind, or to the side of them.

Butterfly Life Cycle Optical Illusion
Source Institutions
This activity is a fun way to show two stages in a Monarch butterfly's life cycle. Learners will create an optical illusion that can be flipped from caterpillar to butterfly.

Partners in Pollination
Source Institutions
In this activity, learners identify the reproductive parts of plants and the animal (bee) structures involved in pollination.

Make Your Own Sea Otter
Source Institutions
In this activity about sea otters, learners make their own "otter whiskers" and use them to find objects underwater.

Sing - Suchomimus Was His Name
Source Institutions
In this activity (located on page 2 of PDF), learners sing together a song that gives details about the dinosaur species Suchomimus (pronounced “Sook-o-mime-us”).

Pet Parasite Detective
Source Institutions
This activity (on pages 19-25) is about fleas and ticks, which are common pet parasites.

Exploring Symbiosis
Source Institutions
In this activity, learners discover which plants and animals have symbiotic relationships and how this impacts each organism.

Make Your Own Deep-Sea Vent
Source Institutions
In this activity, learners make a model of the hot water of a deep sea vent in the cold water of the ocean to learn about one of the ocean's most amazing and bizarre underwater habitats.

Building a Magic Carpet
Source Institutions
In this activity (page 89 of the PDF), learners compare and contrast pitch and roll motions by using a Magic Carpet maze similar to one that was used for Neurolab investigations about microgravity.

X-ray Dinosaurs
Source Institutions
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.

Wolf Postures
Source Institutions
In this activity, learners investigate how wolves communicate with each other through different body postures.

What's in a Dinosaur Name?

In this activity, learners explore the etymology of dinosaur names.

Fishy Observations
Source Institutions
In this activity (page 1 of the PDF under SciGirls Activity: Rabbits), learners will visit a zoo, aquarium, or pet store to view a variety of fish.
