Answer: seasons
Step-by-step explanation: The topic is not specified, so I will choose "seasons" as an example. Five words or ideas related to seasons that learners may not understand are:
Axis: A placeholder for the concept of an imaginary line around which the Earth rotates, causing day and night and the changing of seasons.
Solstice: A placeholder for the concept of the two times a year when the Sun reaches its highest or lowest point in the sky, marking the beginning of summer or winter.
Equinox: A placeholder for the concept of the two times a year when day and night are of equal length, marking the beginning of spring or fall.
Tilt: A placeholder for the concept of the Earth's tilt on its axis, which causes the changing of seasons.
Hemisphere: A placeholder for the concept of one half of the Earth, either the Northern or Southern Hemisphere, which experiences opposite seasons.
To informally assess whether learners use these science words correctly, some activities that could be used are:
Vocabulary matching: Provide a list of science words and their definitions, and ask learners to match them correctly.
Drawing activity: Ask learners to draw a diagram of the Earth's tilt on its axis and label the different seasons.
Role-playing: Assign learners different roles, such as the Earth, Sun, and Moon, and ask them to act out the changing of seasons.
Writing activity: Ask learners to write a short paragraph explaining the difference between solstices and equinoxes.
Discussion: Facilitate a group discussion where learners can share their understanding of the science words and ask questions to clarify any confusion.
