In order to train the machine, the programmer first created two classes: poisonous and non-poisonous fish. How did she create these classes in the teachable machine?
Once the model has been trained, the programmer tests its accuracy. Did the machine determine if the tester fish was classified correctly?

As a class, review the steps needed to complete the Classifying Fish Worksheet below.
When you get started, you will see blue folders like the ones below in your hyperdoc. You will click on the folders to download the fish images onto your Chromebooks.
Students, think about any questions you may have before you start.
Work side-by-side with a partner; each of you should have your own device.
Open the Week 3 Hyperdoc.
Download fish images onto your Chromebook from the three folders: Poisonous, Non-poisonous Fish, and Test Fish Images.
Open the Teachable Machine website.
Load Poisonous Fish Images into Teachable Machine as Class 1.
Rename as Poisonous.
Load Non-poisonous Fish Images into Teachable Machine as Class 2.
Rename as Non-poisonous.
Click "Train Model."
Load and test each of the four Test Fish Images, one at a time, in your Teachable Machine model.
Record the Output % for Test Fish 1 in box A and B.
Repeat for the other Test Fish images.
