The Nervous System

This week we went over the nervous system. The brain in part the central nervous system. Check out this episode about how the brain works. 

 

Human Body System

We have covered the skeletal, muscular, and digestive systems. This week we move on to the circulatory system. Next week the respiratory and nervous system. 

 Check out this video if you want. 

Skeletal System

 More than just people have skeletal systems. Can you name another organism with a skeletal system? 

BOdy Systems

 Our next standard deals with human body systems : 

Use arguments supported by evidence for how the body is a system of interacting subsystems composed of groups of cells.

We will be focused of six systems, 

Cardiovascular , Muscular, Digestive, Skeletal, Respiratory, Nervous.

Cell Structure and Function

 We have learned about the discovery of cell theory. Now we start our understanding of the structure and function of cells. Watch the video below for an introduction into structure and function of cells. 

How Cells were discovered.

There are many scientist that added to our understanding of the cell.  Do you know any of the scientist and what they did? Watch this video to learn more about microscopes and cells.

Year in Review

This year we started out with what makes things alive. We learned about cells and organelles. 
We then learned that cells have genes that control traits, and how these traits are passed on in genetics. We studied Evolution and learned that living things have common ancestors. The year wrapped up with motion and forces and Newton's Laws. 
Of all we studied this year what stands out to you the most? 

Moon Landing and Newton's Law

Why would a lunar lander need thrust to land on the moon? 
Try the Phet Simulator linked below.
Lunar Lander. Phet

Examples of Newton's Laws

A car is racing down the street, the car weaves in and out of traffic and jumps over obstacles. Can you use any of Newton's Law to describe what is happening. 
Maybe this video will help

Gravity is everywhere.

Gavin said to Mya "There is no gravity in space" Mya corrected Gavin and said "Well little brother, I learned in science that, all matter has gravity" Gavin then asked " Then why do things float on the space station?" 
What should Mya say to Gavin? Why do things seem to float on the International Space Station, when all matter has gravity? 

Watch the videos and find out why.

Hockey

A hockey puck is at rest on the ice. What two forces are acting on it? 

Skateboard Physics

You push a skateboard with a force of 6N. If your mass is 60kg,what is the force the skateboard pushes on you? 

Falling objects

If you dropped a feather and a hammer on the moon at the same time would they hit the surface at the same time? 
Watch this video and find out. 

Penny Drop

Legend says that if you drop a penny of the top of the Empire state building it would go right through a person below. Why is this not true?  

Where is gravity?

 Do all object with mass have gravity?  

Newton's 2nd Law of Motion.

Last week we looked at Newton's First Law of motion. This week we examine the parts of the second law of motion. The second law state that the acceleration of an object depends on the mass of the object an the amount of force applied.This law can be written as a formula. What is the formula for Newton's second law of motion?

At rest

A long time ago scientist thought that all things came to a stop. Then the idea was introduced that things would keep going unless something stop it. Which scientists came up with ideas about objects in motion? 

Video is optional, but give it try if you want. 

Types of Friction

Mya was doing some gnarly skateboard tricks. Then she had an epic wipe out. She yelled at Brody that is was all the fault of gravity. Brody replied that it was gravity and friction. Brody went on to explain there were three types of friction. What are the three types of friction that Brody was talking about? 

VCD May 21 2020 

Staying in Place or Moving

Mya said to Clara "You need a force to keep things moving if there was no force then all things will just stop" Clara disagreed saying it was not true because of Newton's First Law of Motion. 
What does Newton's First Law of Motion say about objects in motion?

Evolution Virtual Classroom Day 8

Last Day of Javelina Week

There are three conditions needed for natural selection to occur are variation, fitness, and inheritability In other words are differences present, do the differences help a species survive, and can the difference be passed onto offspring.  Looking at the image below, what is the evidence of natural selection? 

Virtual Classroom 3.27.20

How fit is your Javelina?

One of the three conditions that must be met for natural selection is a difference in fitness. The different traits must help the individual organism survive and reproduce.  How did a different trait help one cactus survive and reproduce?  What evidence in the picture shows that the cactus is reproducing? 

 Virtual Classroom 3.26.20

Javelina Week Continues

There are three conditions that must be met for natural selection to occur.   The first is there must be a variation in characteristics. Different individuals in a population must have different traits. What was the different trait the surviving cactus had?
