Separating Mixtures: How can you separate salt water to make pure and drinkable fresh water?
Design and build a device to separate a mixture of salt water into its components. For example, what device could you build to get the most drinkable water from salt water if you were on a stranded island in the middle of the ocean? Gather data on the amount of water collected and the purity of the water, which can be done through taste tests. Change one variable at a time as you alter your device to obtain more water or more pure water.
Step 1: Observe/question • Question: How can you separate salt water to make pure and drinkable fresh water? …show more content…
o Methods of separating mixtures. o Pros & Cons of each method of separating mixtures.
Step 2: Hypothesis • Sketch a design for your separating mixtures device. Label each part of your device with the object name and briefly describe what is occurring at that point. This part of your project does not have to be typed, but remember to write legible! • Write a short paragraph answering the following question: what part of your research led you to this hypothesis? (Make sure to explain WHY you chose this as your hypothesis.)
Step 3: Experiment • TAKE PICTURES OR VIDEO DURING YOUR EXPERIMENT PROCESS. THIS IS A REQUIRED PORTION OF YOUR WRITE-UP! THE PICTURES/VIDEO WILL ALSO BE GREAT FOR YOUR PRESENTATION! • You will need to collect a lot of information in this experiment. Put this data into TWO separate charts. See back for more information. • In your write-up, make a list of materials, a step-by-step procedure used to build your device (read over your procedure to make sure it makes sense!) and TWO charts (see back). • Build your device. Continue to test throughout your process and make changes as needed. DON’T FORGET TO RECORD YOUR DATA THROUGHOUT THE ENTIRE
