Separation of Mixtures Experiment in a Box
This experiment focuses on the separation of colours in inks using filter paper. The materials page can be printed out, laminated and stuck on the outside of the box so that all materials can be replaced for the next group. A dry erase marker can be used by students to tick off each material as it is returned to the box.
The experiment card can also be printed and laminated and students can write their answers and observations into their books, which will help save on photocopying.
You can choose for your students to just complete the experiment and write their observations on the first experiment card which contains all parts of the experiment and a table to note their observations or you can choose for your students to complete the second experiment card as well which asks students to identify the colours within each ink colour, explain why the different coloured inks spread at differing rates and sketch and label the experiment.
Also listed are my five other Separation of Mixtures experiments. My students rotated through these as part of our unit of study. My students really enjoyed these activities and the organisation of these rotations allowed me to go from group to group and to observe and assist students as required. Once I had set up the boxes, the 6 rotations were a breeze!
