Carbon Dioxide versus Pizza

How does our digestive system relate to global warming? It's simply CO2. With more of a blanket covering the Earth (CO2), our Earth's weather changes, which changes where we need to grow certain crops. Humans are seeing longer droughts and unusually high or low temperatures where they really haven't seen them before. These changes might make it harder to balance our daily food intake like the graph below.

What can you do?

Let's take a close look at what we eat. We'll be using FoodTracker to determine our daily intake for the next week. Here's a quick picture of my intake on Sunday March 23rd. Looks like I need to make some adjustments. Create a profile at SuperTracker

Variables

When we hear of the word 'variables' we think math or least I do, but variables are very important in designing and recording experiments. This week we'll discuss three types of variables:

controlled- things we keep the same.

independent- the one thing we change.

dependent- the measured result.

In order to perform valid experiments like the "Save the Snow" project, we must use these variables correctly or the experiment might not be true.

Save the Snow

    After a successful chicken dissection we noticed that the snow outside is beginning to disappear. The two thoughts seem distant until your freezer breaks down.
    Students will use the scientific method to answer this
                                                 Problem Statement:

              How can we save snow from disappearing outside?

Show Me Chicken!

  This week we dissect chicken wings! We will identify the skeletal muscle, tendons, and fascia of the Muscle System. From the Skeletal System we'll identify the bones, hinge joint, cartilage, and especially the ligaments since Mackenzie had her ACL replaced! We'll also go for red blood cells in the bone marrow along with an artery and a vein from the Circulatory System.

Organizing Your Life.

   As some of you organize your day making sure you have your work done or bring the right stuff to class, scientists are constantly organizing new discoveries! One way we have to make science more understandable is to place what we know about things in groups. That's why we working with Kingdoms in Classification and Body Systems in the Human Body.

    Notice how we organize much like "Sesame Street"!
