“The graphics showing the genetics elements made it easy for kids to follow. The follow-up activity of dog breeds made the lesson realistic since students were familiar with different dog breeds.”

“I love this lesson. The kids enjoy talking about their favorite animals, and being creative about the traits they'd like to change, and the video lesson is filled with interesting, extraordinary animals. The focus is on selection and traits, and the students really understand what that means by the end.”

“The children loved this lesson. I actually didn't print out all the sheets but had them note the answers on one piece of paper (this was to save paper). For the last 15 minutes of the lesson they looked at different types of dogs on a website and created their own puppy from 2 different breeds. It was fun. ”

“They liked the idea of the chicken into a T-Rex. They came up with really great ideas for pet through selection breeding, for instance, pandas, elephants. It so brought up a discussion on how long it would take to breed if the animal only could have one baby at a time. So afterwards, students said if they wanted a pet through selection, they would need an animal that laid eggs or a litter of babies, like cheetahs and turtles. Students also enjoyed making up names for the dogs on the activity.”

“My kids immediately related this Mystery to apples and selection. It was fantastic to hear them refer and relate to something they have already learned about. The best part was the picture of the chicken/dinosaur. They had a good time renaming the animals in the activity. ”

“My students were so excited to hear how scientist could create a dinosaur by process of selection- they oooed and aaaahed at the ideas. The dog worksheets were engaging. Great job. Mystery Science Fridays Rock! ”

“The kids LOVED it! We loved talking about what animals might be in the future and they loved thinking about the animals that they would want! Great reviews from the students! They want to do one every day :] ”

“The additional activity with dog breeds was a huge hit! I let this lesson for a sub to do with the class, and she was very impressed. "It was easy to use, and kept the class engaged the entire time!" ”

“My girls and I loved this lesson,it was very interesting to learn how different breeds came about and the possibility of new breeds to come ...leaves a lot to think about. Learning science this way is learning that is looked forward to each day and talked about with friends and family afterwards. My kids are excited about learning science now!!! thanks so much:) highly recommend:)”
