Schools

Bee habitat lesson

Years 5 and 6

Students are introduced to the diversity of Australia’s native bees and explore bee habitats at school. They explore bees' needs and adaptions, and apply mathematical concepts to visualise bee size variations, to design and build appropriate bee hotels and to map bee habitat. Bee activity depends on flower availability, so in southern parts of Australia this lesson may be best experienced in spring.

    Lesson Plan

    Bee habitat

    Years 5 and 6

Learning hook

  1. Ask your students what they think of when they imagine a bee. Now show them the first slide in the supporting presentation. That was it, right? The European honey bee. Now ask them to try to imagine another bee … Can anyone do it? Lots of people don’t realise, but there are almost 2000 native bee species in Australia!

  2. Have students complete a KWL chart to list what they know (K) about Australian bees, and what they want to know (W). Students can return to the chart at the end of the unit to reflect on their learning (L).

  3. Watch the 4-minute video from Ag Excellence Alliance. Dr Katja Hogendoorn, from the University of Adelaide, discusses native bees and their importance for our natural environment.

  4. Meet another local expert: Dr Tanya Latty is an environmental scientist at the University of Sydney. Students can learn more about insects, and Dr Latty’s role as an insect expert, on the Enquiring Minds website.

University of Adelaide: Facts about native bees

Learning input

  1. View the slides showing native Australian bees.

  2. As a class, explore the school grounds to identify areas where bees might be spotted (areas with flowers in clumps of 1 m2 or more), and annotate a grid or Cartesian coordinate map to show target areas. Decide on a good time to go on a bee hunt.

  3. Allocate specific bee observation sites to small groups of students, identifying the area by its reference on the map, and have them visit each location once a day for three to five days, recording the number of bees observed. As a class, discuss the findings. Is the school a good bee habitat? What would explain the number of bees observed?

  4. Australia has more than 1600 native bee species. Native bees range in scale from 2 mm to 24 mm long. In the video, Dr Hogendoorn says that is like the difference between a rabbit and an elephant. To understand the relative size of native bees, students will create scale illustrations. Show students a short In Situ Science video on scientific illustration to get them started.

    Safety note: Most species of Australian native bees are unlikely or unable to sting. However, it is possible to be allergic to the sting of native bees, and the introduced honey bee may also be present and can sting. Students should observe bees from a distance, and any students with known allergic responses should be accompanied by a teacher.

Learning construction

  1. Students work in groups of five to create to scale scientific illustrations of some native bees to show the range of size. They should decide on the scale they will use and each select a bee to illustrate. They can search for additional images online. The PaDIL website has excellent specimen images. Five suggested bees are shown in the presentation.

    • Quasihesma bee – 2 mm long*

    • Sugarbag bee – 4 mm long

    • Blue banded bee – 11 mm long

    • Teddy bear bee – 12 mm long

    • Great carpenter bee – 24 mm long

    *Note that the Quasihesma bee specimen includes a scale; draw students’ attention to the scale and have them check the actual size of the bee on a ruler.

  2. Students can label their illustration using the bee anatomy slide as a guide. They should be encouraged to notice specific adaptations like the hairs that enable bees to carry pollen ‘baskets’ on their hind legs. More information on bee anatomy is available on the Arizona State University Ask a Biologist website.

Learning input

  1. As a class, discuss what bees need to survive:

    • a food source

    • water

    • a safe nesting area.

    Explain to the students: you’ve already identified a food source; that was how you selected your bee observation sites. Now you are going to build safe nesting areas for native bees.

  2. First, you will need to find out what bees live near you. Use the Aussie Bee website to identify bees that occur in your state, and the type of nest the bee prefers.

    Bee hotels are artificial nesting sites that can help bees who have had their habitats destroyed by land clearing and urbanisation. View the presentation to see some different bee hotels. Notice the size of the holes. As a class, discuss what sized holes would best suit the bees in your area.

Learning construction

  1. Students work in small groups to design and build a bee hotel for their bee observation area. Students should begin by collecting materials they could use to build the hotel. They should focus on recycling materials from school or home, or using natural materials. If you have a nearby reserve or park, students could go on a scavenger hunt to source materials for their bee hotel.

  2. Students then build their hotel, ensuring that the size of the holes is appropriate for the bees they are targeting. Once the hotel is built, students should take a photo and annotate it digitally or physically to show the width of the holes.

  3. Students position their bee hotels and create a bee tour map (using either a grid or a Cartesian coordinate map) showing the best path to take to observe the bee hotels. They encourage parents and community members to take a bee tour around the school grounds using the map.

  4. Students can develop their bee environment further by adding a bee bath and planting a bee-friendly garden (see additional resources).

  5. At the conclusion of the project, students should return to their KWL chart and complete the what I learned (L) column.
