The Missing Link
Source Institutions
In this activity, learners collect, analyze, and interpret information about objects in order to classify them into a cladogram. Use this activity to talk about how scientists classify things.

My Insect
Source Institutions
In this activity, learners use information gathered from a variety of sources to design and make their own insect.

Trash Traits
Source Institutions
In this activity on page 24, learners perform experiments to examine whether or not trash can float, blow around, or wash away.

The Great Plankton Race
Source Institutions
In this activity, learners are challenged to design a planktonic organism that will neither float like a cork nor sink like a stone.

Super Sleuths
Source Institutions
In this physical sciences activity, learners use science to solve a "crime." Learners collect trace evidence (glitter) and explore its characteristics, such as color, size, shape, and light reflection

Sink It
Source Institutions
Learners classify a variety of objects by their characteristics. They then design an experiment to determine which objects float or sink in water and add this characteristic to their classification.

Biodiversity and Evolutionary Trees
Source Institutions
In this interactive activity, learners analyze seashells to explore phylogeny and evolution. Learners identify similar and dissimilar seashells to create a phylogenetic tree.

Coma Cluster of Galaxies
Source Institutions
In this activity, learners will first learn the basics of galaxy classification and grouping.

Match Rock
Source Institutions
In this activity, learners try to figure out who has their matching rock type by reading a description of their rock (no talking!).

Powdery Mildew Fungi: Classification and Ecology
Source Institutions
In this laboratory exercise, learners will discover how many different plant hosts they can find that are infected by the same genus of a powdery mildew fungus, or how many different genera of powdery

What's in a Dinosaur Name?
Source Institutions
In this activity, learners explore the etymology of dinosaur names.

Sink or Swim?
Source Institutions
In this activity, learners identify different plastics in a mystery bag. Learners discover that plastics are classified #1 through #7.

Guess My Rule
Source Institutions
In this math activity, learners play a game and try to be the first player to identify their partner's rule. Learners identify the rule by finding commonalities between three familiar objects.

Scavenger Hunt: A Group Collection
Source Institutions
In this activity, learners are divided into teams.

Print Hints
Source Institutions
In this physical sciences activity, learners explore how forensic investigators collect prints from a crime scene. Learners make hand impressions in damp sand and analyze the patterns they observe.

Paper Mache Dinosaurs
Source Institutions
In this activity (located on page 6 of PDF), learners observe and reproduce the distinctive physical features (i.e. plates, sharp spikes, long necks, deep jaws, claws) of their favorite dinosaurs.

Puzzled Partners
Source Institutions
In this web-based activity, learners try to figure out who in an online chat room has their matching puzzle piece.

Statistics: Creature Features
Source Institutions
In this math activity, learners collect, organize, and analyze a set of data related to types of animals in the temperate forest.

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.
Pattern Families
Source Institutions
In this math activity, learners sort patterns into similar "families" or groups that have the same pattern, but different symbols.
