### Forms of Energy Found in our Rooms

As we finished up our investigation of different forms of energy, we made a picture of a room that had to contain at least one example of each form of energy (mechanical, sound, electrical, thermal, solar.) The kids had to label each form of energy used and/or produced in the picture, then list them out on the side of the page.

### Particles in Different States of Matter

Our particles made out of stickers |

We began by marking off a "jar" on the floor. We just used chairs as our boundaries. We packed ourselves into the "jar" and pretended to be the particles of a solid block of ice, frozen in a jar in the freezer. We were all touching, and no one was really moving much. Then we pretended someone took us out of the freezer and sat us down on the counter of a comfortably-warm room, so we started to slowly melt into a liquid. We began to move around and bump into each other, still within our jar. Finally, someone held us over the stove, so we began to move faster and faster, bumping into each other and the walls of the jar, until finally we became a gas and came out of the jar and flew around the room. We compared the particles of a gas to a sugared-up toddler. Ha ha!! Then we went in reverse and eventually became a liquid, then a solid again.

### The Scientific Method

The last two days of science class have been all about the scientific method. We decided to do an experiment to determine what effects different liquids would have on the physical properties of gummy bears. We used a glass of water as our control, then brought in a glass of vinegar, a glass of water/baking soda, and a glass of water/salt. Before we put the gummy bears in the solutions, we first measured their length, width, thickness, and mass. We also observed their physical traits. Then we added the gummy bears to the solutions and left them overnight. The next day we observed their physical traits and again measured their length, width, and thickness. I hadn't ever done this experiment before, so I was pretty surprised by the differences we saw!!

### Observation vs. Inference

Observation vs. Inference Journal Entry |

The kids will learn about making an inference in language arts, but it never hurts to hit it a little in science as well. This always proves to be a hard concept to grasp at 9-years-old! Really the main idea I wanted the kiddos to grab was that observations are strictly the facts about what's going on. When making an observation in science, it's very important to keep opinions and prior knowledge out of your observations. Those can be brought in later, when analyzing data and deciding which direction to go in an experiment.

One thing that's not on our journal page (and we'll probably add Tuesday) is the idea of using our prior knowledge. We discussed it in class, but forgot to add it in the journal. In class, we talked about how we make an educated guess by using the knowledge we already have that's stored in our little "file folders" in our brain.

### Journal Example

__neatly__dividing our page into three sections, giving each section a title, then completing the activity. What do I know about the number? How can I get to the number? and Word problem where my number is the answer. I kept in fairly simple, since the main goal was to discuss journal guidelines.

### All Possible Combinations

Where the thinking comes in is when I ask them if we've found all possible combinations. It doesn't take long for them to figure out they need some organization for their combination. Enter the tree diagram! We begin listing out our combinations using a tree diagram, then check to make sure we get all possible combinations. We usually only have to do this process two or three times before the kids see the relationship between the tree diagrams and multiplication. When you give kids tedious work, they naturally find the shortcuts on their own! :)

I do point out it's important they understand the process of the tree diagram to see why the multiplication strategy works! It's SO important they understand the "why" of math!!!

### Probability

Today we worked on probability. Probability is the measure of how likely it is something is going to happen. Up till now, most the kids have used words such as these for probability: certain, impossible, more likely, less likely, etc.We take it a step farther so that we may be more precise, and find the probability in fraction form.
