Svante Arrhenius – A Look at the Scientist Behind the Ion Theory

Svante Arrhenius – A Look at the Scientist Behind the Ion Theory

Comprehension Activities

A classroom-ready reading and comprehension activity ⚗️📘 (PDF + H5P) ⚗️📘

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

This resource introduces students to Svante Arrhenius, a Swedish chemist best known for his work on electrolytic dissociation and the behavior of ions in solution. His theories laid the groundwork for how we understand acids, bases, and conductivity – topics that still form a core part of chemistry education today.

The material is structured to be simple and flexible. It includes a short informational text in student-friendly language, along with a worksheet and quiz questions. The tasks are designed so students can work independently or in pairs. It’s suitable for both regular lessons and substitute teaching – no special background knowledge is needed.

What’s included:

• Reading text on Svante Arrhenius and his scientific contributions

• Profile worksheet to summarize the main ideas

• Quiz questions with an answer key

• Two optional extension tasks:
  – Students write their own questions based on the text
  – Exchange and answer questions in pairs

• Formats:
  – PDF (printable and digital)
  – DOCX (editable text only)
  – H5P (interactive version for LMS use, no images)

How it works in the classroom:
I’ve used this type of resource during units on acids and bases or to give context to chemical theories. It also works well when introducing the idea of scientific models and how theories develop over time.

The included H5P version makes it easy to assign digitally. Students can complete the quiz independently and get feedback right away. The extra tasks are helpful for early finishers or when you want to add peer interaction to a quiet reading lesson.

Print it, share it, or upload it – and the lesson’s ready.

Have fun exploring the world of science with your students!
