Development (20 - 25 minutes)
Activity 1: "Protist Safari" - Exploring Diversity in Kingdom Protista (10 - 12 minutes)
-
The teacher divides the class into small groups and provides each group with a "Protist Safari" kit. Each kit includes a microscope, prepared slides of various protists, and a chart with basic information about the protists.
-
The teacher explains the task: students are protist explorers on a "safari" to classify and identify different protists. They are expected to use the microscope and the chart to note the unique features of each protist they observe.
-
Each group selects a slide and places it under the microscope. They then observe the protist's characteristics, such as its shape, movement, and any distinct structures. Students record their findings on a worksheet provided.
-
After a set time, the teacher prompts the students to rotate the slides to the next group. This rotation continues until all groups have observed all the slides.
-
To ensure an engaging and competitive atmosphere, the teacher introduces a 'Protist Detective' game. The aim of the game is for each group to be the first to correctly identify a mystery protist from the slides, based on the clues given on the chart.
-
The teacher asks each group to present their findings, discussing the characteristics of the protists they observed, and the group that correctly identifies the mystery protist gets a small prize.
Activity 2: "Create-a-Protist" - Understanding the Unique Nature of Protists (5 - 7 minutes)
-
The teacher asks the students to get into pairs and provide each pair with a Play-Doh set and an assignment sheet. The assignment sheet contains a list of protist characteristics, such as shape, movement, and cell structures.
-
The teacher instructs the students to use their Play-Doh sets to create a model of a fictional protist, incorporating as many of the protist characteristics from the assignment sheet as possible. They should also give their protist a name and draw a picture of it.
-
After all the pairs have finished creating their protists, the teacher asks them to present their creations. Each pair explains which characteristics their protist has and why they chose them.
-
This activity allows students to demonstrate their understanding of the unique nature of protists and the diversity within the Kingdom Protista in a creative and fun way.
Activity 3: "Protist Problem Solvers" - Applying Knowledge to Real-World Situations (5 - 6 minutes)
-
The teacher divides the class into small groups again and provides each group with a problem card. Each card describes a different real-world situation involving a protist and asks the students to come up with a possible solution.
-
The teacher gives examples of problems, such as "A pond used for drinking water has been contaminated by harmful protists. How can we clean the water to make it safe again?". These problems will challenge the students to apply their knowledge of Kingdom Protista to real-world scenarios.
-
The groups discuss and brainstorm solutions to their problem cards, considering the unique characteristics of protists and how they might be harnessed to solve the problem at hand.
-
After a set time, each group reports back to the class, explaining their problem and the solution they came up with. The teacher encourages other students to give their input and to discuss the different solutions presented.
These activities encourage students to engage with the material in a hands-on and collaborative way, deepening their understanding of the Kingdom Protista and its importance in the natural world.
