A primary teacher employs our microorganism materials in classroom activities.
Revamped But Informal Explanation of Sue's Microorganisms Unit
Let's dive into how Sue, a Year 7/8 teacher, whipped up a captivating unit on microorganisms using the Science Learning Hub resources as her secret ingredient.
Avian Influenza Virus
Sue was all about keeping things relevant, so she picked microorganisms as her topic because it was oh-so topical. Her unit, filled with 12 exciting lessons, included experimenting with growing bacteria and fungi, making it a combination of biology fun and hands-on science. (Just remember to give a quick glance at the Ministry of Education's Safety and Science | Pūtaiao - Guidance for Schools and Kura when planning activities, especially when using Petri dishes!)
Scientist Visits
Sue started by using the Science Learning Hub resources as her learning base. But she knew that adding some real-life experts to the mix would make the unit even more appetizing. For instance, one student's parent—a scientist at the Ruakura Research Centre—visited the class with a colleague, whipping out some snazzy equipment, including Petri dishes! Sue even arranged for scientists to pop by with devices for students to play around with, offering hands-on experiences like peeping at maggots and nits through microscopes.
Learning Goals
Sue and her students set several cool learning intentions for their microorganisms unit:
- Students will understand the differences between bacteria, viruses, and fungi and learn how they can affect us, both positively and negatively.
- Students will learn how to safely grow bacteria and fungi under teacher supervision during fun experiments.
- Students will investigate the impact of factors like temperature, moisture levels, and oxygen access on the growth rate of microorganisms.
- Students will develop their detective skills by making predictions, observing, collecting data, reaching conclusions, and reporting on their experiments' results.
- Students will delve into their science books to research and share info about the topic using scientific terminology.
Campylobacter Bacteria
Did you know that Campylobacter bacteria have a distinctive spiral shape and are a common cause of diarrhea and dysentery? These little critters can wreak havoc when they get into food and water through poor hygiene or contaminated sewage. Most chicken meat houses Campylobacter bacteria, so it's essential to cook chicken well or keep raw meat and its juices away from other food to avoid food poisoning.
Teaching and Learning Activities
The focus of the teaching and learning activities was on bacteria, fungi, and viruses. Students were tasked with researching fun facts about bacteria and exploring the roles of good and bad bacteria in making yogurt and cheese. They also practiced identifying and labeling various shapes of bacteria.
For one experiment, students labeled agar plates and smeared an unwashed fingerprint on one side. After washing their hands with soap and water, they repeated the process. The results showed that washed hands had more bacteria than unwashed hands, sparking some interesting discussions about hand-washing techniques.
Washing Hands
Washing your hands is crucial in preventing the spread of cold and flu viruses.
Fungus Growing Experiment
Students tried to sprout fungus using the Grow your own fungus activity idea, exploring conditions that fungi prefer to thrive in, such as cool temperatures, no oxygen, moisture, and control. For this experiment, students grew fungi on bread, but they quickly lost interest as it took a while to see results. To make it more interesting, the teacher could have documented the process with a series of photographs, which could then be reviewed with the class to observe the effects in each condition.
Assessment
Sue assessed students by having them record their experiments and by giving them a summative assessment test. She evaluated their work based on whether they had a suitable title, aim, hypothesis, methods, and results. Students were also expected to list all their equipment, use proper scientific terms, and draw their diagrams to scale with correct labels.
