Mystery 1: Habitats & Environmental Change

Guess the Habitat

Each student will need:

The teacher needs a printout of the Answer Key (optional, as the answers are also provided in the video).

Activity Summary

In this visual activity, students are shown a landscape and a fossil found in that landscape. Students will examine the fossil and figure out the habitat that used to be in that place.

Mystery 2: Structures & Adaptations, Fossil Evidence, Classification

Guess What These Animals Eat

Each student will need:

The teacher needs a printout of the Answer Key (optional, as the answers are also provided in the video).

Activity Summary

A four-page handout shows skulls of both familiar animals and dinosaurs. Questions prompt students to examine each animal's teeth and figure out what that animal ate. After students complete the handout, show a series of slides and discuss answers.

Mystery 3: Fossil Evidence, Behavior

Outrunning CeeLo

Before class, you need to photocopy worksheets for students and tape printouts of dinosaur footprints to the floor in the right spacing. (We're calling this the dinosaur racetrack.)

For the racetrack, you will need:

For the activity, each student will need:

Activity Summary

Students will try to “outrun” a dinosaur by taking larger steps than the dinosaur took. Using a number line, students will calculate the “stride length” of their classmates. Using a graph, students will also figure out whether their classmates could outrun a stegosaurus, a Tyrannosaurus rex, or a triceratops.

Mystery 4: Heredity, Variation, & Selection

Designer Dogs

Each student will need:

Activity Summary

In this visual activity, students are shown two adult dogs and three puppies. Working in pairs, students will identify the puppy that belongs to these two dogs. To do this, they study the physical traits of the dogs and look for the puppy that shares these traits. Then they mark their choice on the Designer Dogs worksheet, and come up with a name for this mixture of two dog breeds.

Mystery 5: Heredity, Variation, & Selection

Lizard Island

Step 1: Figure out which version of this activity you’ll do.

In this interactive simulation, students will discover how natural selection affects a group of tree-climbing green lizards when their island is invaded by hungry brown lizards.

If you have a group of 15 or more, you can use the step-by-step version of the video above.

If you have a smaller group, you need to use the small group version, which can be used by one student or a group of up to 15 students. If you are using the small group version, print out these instructions for activity prep and the activity. Step-by-step instructions are on the print-out.

Step 2: Print out materials.

Use the chart below to figure out how many copies of each file to print. Depending on your class size, you may have some extra copies, but you shouldn’t run short.
