This term in Science, Stage 2 have been exploring the Living World and have investigated a range of life cycles, including frogs, butterflies, cicadas, the life of a tomato and the importance of bees in helping fruit and flowers to grow through the process of pollination. To deepen their understanding of how pollination works, we conducted a ‘bee pollination experiment’. The class created replicas of the parts of a flower, using pipe cleaners and a plastic cup. We then dipped the end of the ‘stamen’ in paint to represent pollen, each flower having a different coloured paint. Each student had a little bee that then travelled from one flower cup to the next, transferring the paint from the stamen to the next flower’s stigma. This demonstrated the process of pollination.
Our students also provided some commentary on the bee pollination experiment. Their thoughts and observations are as follows:
We made a flower out of pipe cleaners and we made a bee out of a pipe cleaner too. We put paint on it. The paint represents the pollen and we cross-pollinated the paint from flower to flower.
We were doing cross-pollination. We made a cup with pipe cleaners in it. We used three pipe cleaners. We had one facing up and put two in a cross shape. The long one was the stigma and the outside bits were the stamen. We put paint on the stamen to show the pollen. We made a little bee and we held the bee and went to each other’s cups and got the pollen and then took it to another cup’s stigma. This shows pollination.
We put paint on all the stamen parts of the flower and we made a fake bee out of pipe cleaners. We got the bee and put it on the paint which was like pollen then we moved it to another flower to their stigma and this shows pollination.
We did an experiment on pollination because we were learning about bees and how plants grow and how bees help to pollinate. We made pretend flowers out of a plastic cup, three pipe cleaners and paint. Then we put paint on all of the parts which were the stamen and then we made bees out of pipe cleaners and then we grabbed the bees and we put the paint on the bees and we transferred it to our own cup. It shows how bees cross-pollinate.
We got a cup and we cut the top off it so it was short. Then we got three pipe cleaners and we twisted them and bent them to make a flower. We put paint on the end of the pipe cleaners to represent pollen. Then we made some bees and they flew across to one flower and then another and then another. Then it spread the pollen.
Well, you see we had some paint and we put it on the end of the pipe cleaners. We twisted them into flowers. The paint was for the pollen. We made a bee then we put the bee on the paint and it stuck to the bee like actual pollen. Then the bee flew around to another person’s flower and left the pollen there.
We cut a plastic cup in half and then we took two pipe cleaners and crossed them over each other. Then we tied a pipe cleaner on to represent the stigma. Then we put that inside the plastic cup. We put paint on the fur things around the outside and then we made bees out of yellow pipe cleaners and we cross-pollinated by putting a part of the bee on someone else’s flower and then bringing it back to our own.
We did this experiment because we wanted to see how bees get the pollen from the flowers. We got a see-through plastic cup and some pipe cleaners. We made the pipe cleaners into parts of the flowers and we put a long pipe cleaner in the middle to act as the stigma. We put paint on the parts that were the stamen. It represented the pollen. We made bees and then we went around getting the pollen from the stamen and put the pollen onto the stigma of other people’s flowers. This showed how bees get pollen from each other’s flowers and help to pollinate. This shows us how flowers grow.
We made flowers out of pipe cleaners, paint and a cup. We also made a bee out of pipe cleaners and we looked at cross-pollinating with paint, going from one stamen to the stigma of plants.

We made flowers and bees. We dipped the stamens into paint and then we got the little bees and went onto the paint on the stamens and we got the paint onto the bees and the paint represented pollen and we moved the bee along with our hand and put the pollen from that flower onto the stigma of our own flower.

We got three pipe cleaners and created a model of a flower. We dipped the stamens in paint which represented the pollen. We also made a bee out of pipe cleaners. Our bees then flew around and picked up paint, or pollen, from other stamen and returned it to the tall pipe cleaner in the middle which was the stigma, to show how bees help to cross-pollinate. In the end there was lots of different colour paint on the stigma and this was the cross-pollination.
Did you know that bees help the world grow plants like trees to help us breathe and they also give us yummy honey that can help our throats when we are sick. Bees pollinate flowers to help them grow. We did an experiment to show how this happens. We used lots of pipe cleaners and paint in our experiment. What we did was made the pipe cleaners into little bees and flowers. The pipe cleaners were parts of the flower. We used paint on the stamen to show that was pollen. The bees went to the stamen and the paint stuck to them and this shows how the pollen sticks to the bee and is transferred back to another flower. This is the pollination process.
We did the experiment to show how bees pollinate and also why they pollinate. We made a cup, we got two pipe cleaners and then we crossed them over and then we got a third pipe cleaner and wrapped it around it. The pipe cleaners were parts of a flower. We put this in a cup. We got a pipe cleaner and made it into a bee too. We put paint on the end of the pipe cleaners which was our pollen and then we got our bee and got paint (pollen) from one flower and went to the stigma of another flower and we kept doing that. At the end, my stigma had lots of colours which showed that lots of bees carrying pollen went onto my stigma.
