All About An Animal, Post 1

Posted on by

Introduction

This animal is one of the oldest species on Earth. In fact, it is 550 million years old! This animal lives in the ocean, has an umbrella like head, and HAS NO BRAIN OR NERVOUS SYSTEM! You guessed it! It’s a jelly fish!

Jelly fish live in every ocean of the world and are classified as an invertebrate. They live about one year in the wild and can range anywhere from 2 centimeters, to 2 meters! There are about 2,000 species of jelly fish known to us today!

Diet

Because of the emense amount of sub species of jelly fish, their diets can be very different. Most commonly, they will eat things like fish, shrimp, and crabs. But some jelly fish eat plants and even other sub species of jelly fish!

Distribution

Jelly fish live in all oceans of the world. They are most heavily distributed in salt water, but certain types can live in fresh water. These jelly fish are called hydrozoans, but not all hydrozoans live in fresh water.

Fun Facts

1. Jelly fish are plankton, meaning they drift and float around because they are not strong swimmers!

2. Some jelly fish are as big as a human, and some as big as a pin head!

3. In some parts of the world, a million jelly fish can come together in a bloom!

My Trip to The Beginning of Life!

Posted on by

If you could go anywhere in time once round-trip, where would you go and why? This is a difficult question. So many places to go, so many events to witness, where to go? I have always been so curious about how life came to be on Earth. The theory of cell reproduction requires that a cell is existent for that cell to replicate itself, so how did the first cell come to be? A few theories are out there such as self replicating RNA cells (Ribonucleic Acid), but this has never been proven. So how did the first cell in existence come to be? That is what I would want to figure out. First, I would find the cell and figure out what it was. I would also want to document how it came to be. I wonder what kind of cell it was! I would also like to know if this first cell even was on Earth and not somewhere else. But, I would have to be careful not to kill it and end all life on Earth. That’s a scary thought!

Meet Humphrey!!!

Posted on by

So as many of you know two months ago I bought Humphrey. Humphrey is now about four months old and is a roborovski hamster.

Robo Facts

 

Robo hamsters were named after an explorer. These are the smallest hamster in the genus Phodopus and are two inches fully grown. They are commonly mistaken as herbivores but they are actually omnivores. These guys will eat plants, incests, and meat. Meaning these guys are also scavengers.

 

Humprhey is getting used to me and is able to be picked up now. Humphrey is very much enjoying his cage that is double the size than the ones in the pet store, which are actually too small.

Chickens???

Posted on by

So for a while, I have taken horseback riding lessons at a farm. At this farm they keep chickens. So for a while I hung out with the chickens a lot. And by a lot I mean A LOT. So after while I thought it would be fun to get chickens. So now my family will be keeping backyard chickens.

 

We have already ordered the coop and it’s on the way. We will be making the run too. The chickens we plan on getting are Rhode Island Red chickens which lay about 250 eggs a year. These chickens are very friendly and good layers. Here is a picture.

We will be getting three. I will do a post and a video when we get them.

 

Awesome Electric House Project!!!

Posted on by

For the past month or so we had been working on an electric house project in science. We did this to learn about our circuit unit. Basically, we had to make a cardboard box, and on top of that box, we had to make circuits with different appliances for our houses. We used lights, motors, and buzzers.

Here is a video of my group explaining our house.

The Science Behind the Electric House from DA MS Student Council on Vimeo.

How It Works:

Our circuits work by having electrons confined to one path, the wire. Voltage, the difference in electrical potential makes the electrons flow. When the electrons flow through the appliances, the appliances transform that electrical energy into different forms, such as mechanical energy, light, and sound.
