Science
Jeremy carried out a hands‑on experiment to extract DNA from a banana by mashing the fruit, mixing it with water, salt and soap, and then filtering the slurry. He observed that when chilled ethanol was added, a whitish, stringy substance formed at the liquid boundary, which he collected with a metal tool. Through this process Jeremy learned that DNA is hidden inside the cells of living things and can be separated by breaking cell walls and precipitating the genetic material. He also practiced careful observation and recording of the steps, gaining a basic understanding of biological laboratory techniques.
English
Jeremy followed a set of written, step‑by‑step instructions to guide his banana DNA experiment, reading each stage and sequencing the actions in the correct order. He used scientific vocabulary such as "filter," "ethanol," and "DNA" while describing what he saw, which helped him practice decoding informational text. By summarising the procedure and noting the appearance of the DNA strands, Jeremy reinforced his comprehension of procedural language and learned how to communicate scientific findings clearly.
Tips
To deepen Jeremy’s learning, you could (1) create a simple lab journal where he draws each step and writes a short reflection on what happened and why; (2) compare banana DNA with DNA from another fruit or vegetable to discuss similarities and differences in cell structure; (3) stage a role‑play where Jeremy acts as a scientist presenting his findings to a “science panel,” encouraging oral communication and confidence; and (4) explore a virtual microscope simulation to view magnified images of DNA strands, linking the real‑world extract to digital models.
