Nervous System

 

 

In Science we are learning about the Nervous System

 

The nervous system is a very, very important system in the human body because it is the part of the body that tells your arms and legs to move, your eyes to blink and your mouth to form words. It lets the body feel things, if you stub your toe or get tickled the reason you can feel it is because of the nervous system. The two main parts of the nervous system are the brain, and the spinal cord. The brain is located inside of your skull and your spinal cord is a bundle of nerves surrounded by bones called vertebrae. When you touch something, a neuron is stimulated. It creates an electrical impulse that travels from neuron to neuron using chemicals called neurotransmitters. Did you know that in the time it takes for you to say misisipi three times, an electrical impulse could travel across a football field and back? We would like to learn more about some of the diseases associated with the nervous system and what causes them.

Shark Tank!

Howdy People! In Science this month we have been doing a simulation using Sharks, Minnows and Seaweed. Here is a graph that represents how it went:

 

Let me set up the game for you.

Sharks can run around and eat the minnows. But for the shark(s) to survive they have to eat two minnows. If a shark wants to reproduce, they have to eat the two they need to survive and at least one more to reproduce

Minnows can only fast walk to seaweed and for them to survive, they have to eat at least one seaweed. For minnows to reproduce, they have to eat the one seaweed they need to survive and then at least one more seaweed to reproduce.

Seaweed is anchored to the ocean floor and they can not move. They do not have to eat anything to survive, because they are there only to help the minnows survive. But, at the end of every round, the population of the seaweed that was left standing is doubled, because seaweed can only reproduce once.

If you take the rules I just put out into account, you will be able to imagine how the game went.

Bye, Bye for now!

A 3D Image Of An Atom

What’s up world! In science we have been studying what atoms look like and what they do. We had a test where we had to recreate an atom as acuratly as we could using a 3D printer website. We only had 15 minutes to do it. We had a choice between Hydrogen, Helium, Lithium and Beryllium and I chose Helium. Here it is:

OK, now I will explain to you what in the world all of the spheres are in this picture. The green spheres in the middle are called Protons. The blue spheres in the middle are called Neutrons. The two red spheres on the outside are called electrons and electrons have to be the same amount as protons to have a stable atom because, protons are +1 and electrons are -1 so they cancel each other out.

5th Grade Big Bang

Hey Guys! For the first month of 5th grade science we have been studying the big bang and what it’s importance was! We had to get creative and bring in things from home to make a replica of the big bang! Here is My project!

 

One Accuracy that we had was that all the sparkles spread out really randomly across the paper just like all the atoms spreading across the universe in the big bang. One inaccuracy that we had was that the big bang happened in a millionth of a millionth of a millionth of a millionth of a second but our took a while because the baking soda had to react with the vinegar so that the sparkles could go over the cup.

 

Thanks for watching!:)
