Create the T-Chart below in your NBAs you are looking at the two bottles that are going around the room find 5-6 ways they are similar and ways they are different.

The purpose of the lab was to test each substance against each other and determine which substances were soluble and which were insoluble. Once you have determined the solubility of each substance you should be able to determine what 4 substances are in each bottle (see slide #2) and more specifically what is in each layer of bottle A and what is in each layer of bottle B.

Copy the ball and stick models of three of your ingredients—they need to be exactly duplicated in your NB

Solubility Data Table

Students who did the lab tested each chemical against each other—hint a grid might be the best type of table to create.

KEEP the following in MIND… Solubility data must be recorded for every pairing of the

chemicals. Keep track of which ingredient might be denser Data table should be clear, concise, and efficient. Keep in mind tests can be done for some mixtures of

substances as well.

Creating the wave toy recipe (nb title)

Sketch each wave toy and label which chemical or chemicals are in each layer.

Remember that there are 4 ingredients in each bottle.

Wave Toy :Analysis & Reflection Questions

In your NB, copy questions and answer IN COMPLETE SENTENCESPlease skip a line between the answer of one question and the start of the

next

1. Write out the recipe for one of the wave toys (red or purple).

2. If you were to dye an oil based paint, would you want to use the purple dye or the red dye? Explain your reasoning.

3. There were 4 substances in each bottle. Why were there only 2 layers in each wave bottle? Use evidence from your data chart and key vocabulary in your explanation.

4. Did the red dye and purple dye dissolve the same way in all substances? How did this effect your recipe?
