Voting On Our Classroom Pet

What kind of pet are we going with? Let’s decide.

Trait Similarities

Notice that among related animals, general traits are similar. (i.e. all of the Elephant varieties had 4 legs, a trunk and tusks)

But what if we COULD genetically alter a pet to produce a new species with the traits of several species? What would your ideal designer pet be??

Choosing a base pet

Discuss at your table ideas for a base pet. If you have your phone, scan the QR codes at the front if you didn’t already.

What pet do we want to use as the class pet? Join the discussion on Today’s meet.

I’d like to end up with this being our class mascot. Really spend some time thinking of good ideas for your animal that will represent the class!

Choosing traits

We want to alter 7 traits for our pet.

What are your ideas for traits? Post them to Today’s meet.A.) Animal size

B.) Body covering (skin? scales? Armor?

C.) Number of arms/legs

D.) Coloration

E.) Number of eyes

F.) Type of tail

G.) Hand/Foot type

Pick your traits

Make your choices for YOUR INDIVIDUAL animal.

Draw your perfect pet

Name your perfect pet species

Describe your pet in detail, focusing on: traits from the original species that you changed

Why you feel that your traits are more beneficial. What are the advantages of your pet over the original?

Exit Slip Reflection:
