Hello my name is Christian Herrera. My interests are doing math,science,and a little bit reading. My favorite subject is math. My favorite topic in science is machines and my least favorite topic is the water cycle.I'll like to learn about plants & animals this year in my science class.

In lesson one I learned about what the processes of science are. Science is gathering information about the natural world. There are many processes of science.Observing means using one or more of your senses to gather information. Observing a specific thing tells you what that thing is about, the things it does and the things it likes. A quantitative observation deals with numbers or amounts. For example, if you look in the field and notice that there are seventeen orange groves thats a quantitative observation. A qualitative observation deals with descriptions that cannot be expressed in numbers. For example, if you notice the color of an object or you state that a certain food tastes a certain way that is qualitative observation.When you explain or interpret the things you observe, you are inferring. For example, I changed my puppy food to a new brand and noticed that they ate it all compared to the old one that they never finished. So i'm inferring that the first food i was giving my puppy's didn't taste good.Predicting means making a statement or a claim about what will happen in the future based on past experience or evidence. For example, there were plants that grew on the palm trees outside last year. The plant attracted bees and flies. Within a month the bees ate the plant and it died. My prediction is that the palm tree will grow the plants again in the spring and the bees and flies will return. Classifying is the grouping together of items that are alike in some ways. For example, a group of kids in the everglades documented data on the alligators seen on a monthly basis to classify if there were new alligators coming in different months.Making models involves creating representations of complex objects or processes. For example, models often involve plugging information into a graph or chart. Evaluating involves comparing observations and data to reach a conclusion about them. For example, Samatha planted green pepper seeds in the backyard and some in the field next to her house and she evaluated that the peppers in the field were growing much faster then the peppers in her backyard so she concluded that the fields are better to grow the peppers. A scientific investigation is the way in which scientists study the natural world. For example, let's say I have a problem, my moms car won't start. If I put gas in my car, it will start.First, my mom would ask for a ride to the gas station. She takes a five gallon gas can and fills it with gasoline, pays and gets aride back to the car. Once the gasoline is in the tank, she ties to start the car, and it works so my conclusion is that if I put gas in the car it will start.

Growing crystals-what factors affect size and weight?

promblem statement;Does differnt products affect the crystal growth

hypothesis; i think the crystal in bleach will grow faster. materials;alchoal bleach water sugar cups. independent varible;the growht dependentt varible;type of material controlled varible;amount of material;type of material;place;tepmepture;cup. crystallization crystallization is the process of solid crystals are harding from it liguid state to it solid state. A crystal or crystallition solids is a material whose constituent and crystal formation is known as c'or in some cases it comes form a gas.crystallization is a chemical process.

In which the weight transfer into a solid form from a liguid state. pic of crystal As mentioned above, a crystal is formed following a well-defined pattern, or structure, dictated by forces acting at the molecular level.

crystal form

resust water 1)0.0 2)0.07 3)0.12 4)0.19 bleach 1)0.0 2)0.03 3)0.06 4)0.10 alchoal 1)0.0 2)0.05 3)0.9 4)0.15 hypothesis;my hypothesis was wrong.

conclusion;In water the crystals grew faster.alchoal was second.and bleach was the least.my hypothesis was wrong.crystal grow faster in water.
