Featured Reviews

“The best part was activity and videos that replayed steps over and over again so I could monitor around the room and help out kids without having to be in one spot! The students loved being the 'bees' and pollinating their flowers. Plus when we went on a field trip that week, the students observed butterflies and bees pollinating on a flower plant. They were completely absorbed. They couldn't believe they were seeing it in REAL life! :) Awesome connection and experience with the lesson and in-class experiment.”
· Sadie · Teacher
“My students loved this activity and are still buzzing about it! I love the step by step directions and the questions that get the students thinking about the topic. I can't wait to try more mysteries!”
· Suzi · Teacher
“My students loved creating their own bees and flowers. They all truly understand the bees purpose in the reproduction of flowers. It was also great for a display for our open house. The students loved telling their parents what they did and what the purpose was of their experiment. ”
· Elizabeth · Teacher
“The students loved it! I even had a child who said he wanted to go home and research more about pollination! I love that their is an interesting video with questions and then an interactive activity at the end. It definitely helps to keep the students interested and deepens their learning!”

· Lisa · Teacher
“First time teaching it, and my students and I LOVED all of it! Thanks for putting this together! Can't wait to try out more Mysteries, and to see what new ones are added, too! ”
· Meghan · Teacher
“This lesson was so much fun, best yet!”
· Debbie · Teacher
“It was excellent! The videos of the bees were fantastic because they showed all of the pollen. Very close up pictures. Loved the video showing the steps in making the flower. Loved that is constantly repeated the steps over and over for students to use as a guide.”
· Christine · Teacher
“We had a blast trying to solve the mystery of why the vanilla plant didn't make seeds by itself! We also loved the pollination activity!”
· Christina · Homeschooler
“The videos were spot on! The step-by-step directions with looping video for the activity were perfect for my third graders.”
· · Teacher
“It was very interesting to ear their answers to why bees are important for pollination. They actually had no idea, most thought it was just to make honey. The activity to make model flowers and how the flower needs pollen from another plant helped the children understand very well. After the lesson I took the class out to see the cherry blossoms and a variety of flowers. They were so excited to see the pollen inside of the flowers and tried themselves to pollinate the flowers!”
· Joanne · Teacher
“The best part was when we went to the Mother's Day Plant sale and the children were trying to locate the "sticky stigma" and "pollen" in their real plants. This showed me that they really "got" the lesson. Fantastic!”
· Linda · Teacher
“This was such a fun lesson! A support teacher kept raving about how wonderful this lesson was as I was teaching it - she couldn't believe how hands on and entertaining it was! The best part is now my students are interested in finding out more about how monkeys are pollinators!”
· Stephanie · Teacher
“Phenomenal! Our students loved the activity and were so excited. It is always great when the teacher learns something too.”
· Cindy · Teacher
“The directions were easy to follow and it really illustrated pollination concretely to the kids. The students can really follow along with the narrative to solve how flowers make seeds.”
· Dawn · Admin
“What a great way to help students understand how and why bees pollinate! The activity was very effective. Students are really listening and learning during the videos.”
· Marianne · Teacher
“The lesson is really engaging and requires very little prep time. The kids loved it. Making the flower models was also awesome-the step by step video instructions are mega-being able to put the visual on a loop while the teacher circulates to help kids complete it is very effective. The kids loved making their insects and cross pollinating their flowers. The students really made a connection to the lesson and want to inspect every flower they see now for the pollen dusters and sticky stigma.”
· Britt · Teacher
“I love the graphics. They make it so clear to my students what is happening. I also appreciate the anticipation of questions students might ask. The information is there for them to see and hear. ”

Prep Instructions

We suggest students work in pairs. Homeschool students can work on their own, but will need to make two flower models and may need a partner to help with a few steps of the activity.

Prepare “Pollen” Cups

So they can observe that pollen is transferred from one flower to another, you will need to provide students with two different kinds of pollen. In half the cups, spoon about a tablespoon of one of the “pollen” types (e.g. cinnamon). In the other half of the cups, spoon about a tablespoon of the other “pollen” type (e.g. ground coffee). Groups of four students will be sharing two cups of “pollen."

Classroom Management Tip

To avoid distractions, we suggest waiting to distribute the “pollen” cups to students until Step 9 of the activity.
