Science Laboratory Activity - 6th Grade Copper Sulphate Crystals
Full Name: __________________________ 6th Grade: _________________ Report date: Monday, September 23rd
Date of Delivery: ______________
List of Materials per Group • • • • • •
Glass jar, like jelly jar (500 cc). Latex gloves. White coat buttons. Plastic-coated wire. Paper clips. Paper Towel.
Procedure All these procedures will be done under the teacher’s instructions and supervision. 1. 2. 3. 4.
Place the paper towel over the tiles of the lab working surface. Place the glass jar over the paper towel. Pour the boiling water very carefully and slowly into the glass jar. The person manipulating the Copper Sulphate must be wearing gloves, goggles and face mask. 5. Start adding the copper sulphate until the solution gets oversaturated. Stir the water and verify that it doesn’t dissolve any more copper sulphate. 6. Unfold the paper clip and pass it through one of the button holes and secure it in the plastic-coated wire. 7. Place the wire around the jar’s mouth so the clip and button are hanging immersed in the blue solution. 8. Let it rest for 24 hours. Then pull out the wire and draw and measure the crystals formed. Record time and day of measurement. 9. Let it rest for additional 24 hours. Then pull out the wire and draw and measure the crystals formed. Record time and day of measurement. 10. Observe and comment.
