Students will investigate the characteristics of limestone.
In this lesson, students will investigate the characteristics of limestone. It may be used as a standalone lesson, or follow on from the Lesson: Introduction to the Intertidal.
Choose whether to complete the investigation as a whole class, or in small groups.
As part of the investigation, students will be required to hit one of the pieces of limestone with a hammer. Ensure you have a suitable outdoor space to complete this part of the activity. Students should wear protective footwear and eyewear.
Students will each require a copy of Student Worksheet: Learning Limestone.
Equipment required (per group):
- 4 pieces of limestone – try your science equipment supplier or local garden or brick supplier to obtain limestone pieces. As a rough guide, source pieces approximately the size of a small coffee cup.
- a hammer
- safety gasses (for each student)
- 2 containers (each one large enough to fit one piece of limestone submerged in a liquid in)
- vinegar (enough to cover a piece of limestone in one of the above mentioned containers)
- water (enough to cover a piece of limestone in one of the above mentioned containers)
- a piece of coarse sandpaper
- Divide students into small groups. Provide each group with investigation materials, and each student with a copy of Student Worksheet: Learning Limestone.
- Ask students to read through each ‘test’ and predict what will occur in each.
- Allow time for students to complete each investigation and make their observations.
- Engage students in a class discussion about the tests conducted and the observations made. How did their observations compare with their predictions?
