Lesson ideas by grade band
Kindergarten to grade 2
- Needs of a dog (K-LS1-1): look at photos of dogs eating, drinking and resting, list what every dog needs, then complete the worksheet. Extend: compare with what a plant needs.
- Safe snacks sort: play Snack or Nope? together on the board and talk about why some human foods are not safe for dogs.
Grades 3 to 5
- How dogs sense the world (4-LS1-2): read the fact sheet, then have groups draw a model showing a dog seeing a ball, the information reaching its brain, and how it responds.
- Reading signals: play Wag Signals as a class and record which body parts gave the best clues.
- Traits in a litter (3-LS3-1): use the traits worksheet data table to compare puppies and parents.
Grades 6 to 8
- Selective breeding (MS-LS4-5): students research how breed groups were developed for jobs such as herding, hunting or guarding, using the breed groups guide and the AKC, then complete part B of the traits worksheet.
- Test the toy color claim: play Fetch Spotter, read Can dogs see color?, and design a fair test of which ball color is easiest to spot on grass.
Grades 9 to 12
- Reading real science: students pick a paper from our research page, find the question, method, sample size and main finding, and judge how far the result can be generalized (for example, a study of one breed). No NGSS code is claimed for this activity.
