Let's take a look at the tools given in the answer choices:

A thermometer is used to measure the temperature of something, or to determine how hot or cold something is. 

A scale is used to determine the weight of an object. 

A measuring cup is used to determine the amount of something. Measuring cups are often used in baking. For example, if a recipe called for two cups of sugar, you would use a measuring cup to measure out two cups of sugar.  

A ruler is used to measure the length of something. 

Based on the question, we are trying to determine how hot the hot chocolate is, so we would use a thermometer.

Observable properties are characteristics or things about materials or objects that we can describe using our five senses. Color, texture, hardness, and flexibility are all things we can determine with our senses.

The term observable means to be noticed or perceived. If something is noticeable, I can touch it, taste it, see it, hear it, or feel it. We can observe the properties of a material and use it to determine what it is or how to classify it.

Another term for materials is matter. Matter is what things are made of. All materials, objects, and living things are made of matter.

The observable properties listed give us a clue to what the mystery object is. We know the object needs to be yellow, soft, smooth, and it should not bounce. An apple is typically not yellow, a ping pong ball IS bouncy, and basketballs are generally bouncy and orange, so they are not a match. That leaves a banana which meets all the observable properties.

The object that Janice is describing is a die or pair of dice. They are bouncy, hard, smooth, and black and white. The other choices are black and white but don't meet the other observable properties.

Observable properties are characteristics of an object, person, or material. We use our five senses to make these observations. From the pictures, we can see what the two flowers look like and use this information to help match the correct data table.
