Mixtures and Solutions
For today's experiment you will need
Sand and Salt
Directions:
Wear your safety goggles!
1. Perform this fun experiment with your parent, sibling, or friend.
2. Use two of the three beakers and fill them with water.
3. In the first beaker filled with water, add two teaspoons of salt. Record what your eyes see in your Science Notebook.
4. In the second beaker also filled with water, add two teaspoons of salt. Record your observations in your Science Notebook.
5. Now, stir each of the beakers and their contents. Record what you see. Using your thinking tank, predict what would occur if sand and salt were stirred together in water. Using the third beaker, fill it up with water.
6. Now add one teaspoon of salt and one teaspoon of sand and stir. Record these observations in your Science Notebook and compare them to your prediction.
7. Now go to PERIODIC TABLE (color) and find the compounds of Salt which are sodium and chlorine Record in your notebook where they appear in the video. Now do to the PERIODIC TABLE (star) and write the element symbol and atomic number for sodium and chlorine.
Your notebook should look like this
Sodium is at the ______ of the video. Element symbol = Atomic Number =
Chlorine is at the ______ of the video. Element symbol = Atomic Number =
8. Sand can be made from different elements. One form of sand is SiO2. For extra credit. Write in your notebook, what two elements would be in the sand molecule with the chemical makeup of SiO2.
