“The kids were always really surprised by the fruits they didn't know, specifically what the insides looked like! They also really enjoyed sorting the cards. I appreciate that the worksheet had lines for them to write down their evidence - it was great to be able to see their thinking. ”

“I taught this lesson to three different third grade classes. They LOVED it! They really began to notice the similarities and differences of the seeds, leaves, and flowers. Great lesson that kept everyone engaged,”

“Watching third graders have discussions about what traits prove that certain plants are related to the same wild plant was amazing. The lesson furthered their thinking and they have the basics of heredity down!”

“The kids really liked the Odd One Out game. Lots of exclamations like "What????" The card sorting was a great followup-challenging and intriguing to them. Thanks! We appreciate your curriculum so much. We are all learning.”

“The use of the technology with the pictures of the various fruits, flowers, seeds, leaves really helped to 'show' students exactly what I was trying to teach them about plant traits. They were easily able to match like plants with the cards based on the 'preparation' from the tech lesson.”

“My kids say the best part was the "Odd One Out" activity. I enjoyed the fruit cards, a couple of them stumped me, but it was interesting to see how comparing the leaves, insides and flowers helped to show the relation between the fruits.”

“"This was the best lesson I ever had"--N, age 9 "It's really cool how you put fruits together and see how they compare!" --KB, age 8 "Cool." -M, age 7 "AWESOME!...Because!" -J, age 7 "I have never seen anything like this!" -S, age 7 "I bet I can make a watermelon boat! Probably using the rind." --A, age 10 "Illuminating lesson!" --M, age 38 Great work. This had the kids engaged start to finish. ---K, age 35 ;)”

“I never ever knew that pumpkins could be in different shades of color and sizes and that I never knew varieties could change roses, fruits, corn and any other fruit or vegetable. Signed Kennedy Bruce”

“Very engaging to try to which one didn't belong - lots of great discussion while predicting and then the "ohhhh as they saw the seeds with the leaves and flowers. The sorting activity at the end solidified their thinking. Loved it. ”

“I love this series of explorations. The connection to foods they eat make the concepts so relatable and easy to talk about in our everyday lives. This means the content and ideas presented really stick!”

“My students were amazed at all the varieties of pumpkins and fruit that are available today as compared to the past! They also became more aware of similarities and differences during "Odd one out"”

“This was swell. The boys enjoyed the Odd One Out game. It would be interesting to add some of the vegetables in the discussion we well, although that wouldn't go with your 'flowers' theme. But you could add it as an extra.”
