Joseph John Thomson – The Discovery of the Electron

Joseph John Thomson – The Discovery of the Electron

Comprehension Activities

A ready-to-use science resource for grades 7–10 (PDF + H5P) ⚛️📘

A printable and digital resource for grades 7–10 science and cross-curricular teaching 🧪🧠

This classroom resource introduces students to Joseph John Thomson, the physicist who discovered the electron and helped shape our modern understanding of atomic structure. His work not only earned him a Nobel Prize, but also laid the groundwork for the atomic models students learn about in middle and high school.

The material is designed to be easy to use – even if you’re short on prep time. The reading text is short and accessible, followed by a structured worksheet and quiz questions. It’s suitable for science lessons focused on atomic theory or the history of chemistry, but it also works well in substitute teaching settings since students can work through it independently.

Included in this resource:

• A short informational text on J.J. Thomson

• A profile worksheet to help students summarize key points

• Quiz questions (with solution key)

• Two extension activities:
  – Students write their own questions based on the reading
  – Exchange and answer a partner’s questions

• File formats:
  – PDF (for printing or digital use)
  – DOCX (editable, text only)
  – H5P version (interactive, for learning platforms)

How I use it in class:
I like using materials like this at the start of a unit on atomic structure or when we discuss the development of scientific models. It gives students a chance to see how our current understanding has evolved – and reminds them that science is built on the ideas of real people.

The H5P version allows for digital delivery and self-checking, making it great for homework or blended learning. It also gives students the chance to reflect, work at their own pace, or collaborate in pairs.

Quick to prepare, easy to adapt – and a great way to connect abstract content to the scientists who helped shape it.

Have fun exploring the world of science with your students!
