Human Body: Frogs & Grasshoppers

Human Body: All Systems

Human Body: Skeletal

Horse, deer, cow, turtle skeleton pieces

Sarah found this skeleton and donated to our classroom!

Human Body: Urinary (Excretory) System

Kidneys filter the blood.

The following are pig kidneys with ureters attached.

This one has dye:

This one does not have dye:

Human Body: Nervous System

What a bunch of BRAINiacs!

This sheep brain includes the cerebrum, cerebellum, and brain stem!

Human Body: Circulatory System

Making Blood...

• Start with plasma (represented by yellow food coloring + water)
• Add red blood cells (cheerios soaked in red food coloring + water)
• Notice what happened to the color of blood!
• Add white blood cells (white marshmellows)
• Add platelets (tiny pieces of a peppermint marshmellow)
• Notice how sticky the platelets are!

Pig Heart Dissection...

The heart is made up of cardiac tissue. We looked at the structure of the heart: right atrium, left atrium, right ventricle, left ventricle, aorta, and vena cava. We also discussed the function of the heart and the function of valves in the heart.

Heart Rate Lab:

Human Body: Digestive System

Did you know that the whole digestive tract can measure 914 cm when stretched out!?

Digestion in the Stomach:

Test Tube 1: Pepsin

Test Tube 2: Hydrochloric Acid

Test Tube 3: Gastric Juices (Pepsin + Hydrochloric Acid)

Egg whites were placed in all three test tubes. 

Test tubes were heated to body temperature, 37 degrees Celsius. 

Recipes for Genetics

We have some cute dogs in the seventh grade!

Students used DNA strips (set of instructions) to figure out the phenotypes for their dog.

ExCELLent Cell Paintings

Ms. Anna Hodge, our former art teacher, volunteered her time to help us out with our painting techniques! The cells look FABULOUS!

Genetics: Strawberry DNA Extraction Lab

Cells: Protists

Cells: Bacteria

Bacteria can be helpful to organisms and the environment

● Bacteria are in our digestive system and aid in breaking down and absorbing food. 

● Bacteria are used to make a variety of foods including cheese and yogurt. 

● Bacteria can decompose dead organisms and release those nutrients back into the environment. 

Bacteria can be harmful to organisms and the environment 

● Bacteria can be pathogens and cause diseases like strep throat, food poisoning, and tuberculosis. 

● Bacteria, such as wheat blight can infect plants that are used as crops.

Cells: Shrink Film Art

Seventh graders partnered with Ms. Dottie's K4 classes and Ms. Stutts' class to create animal and plant cells using shrinky dink. We loved combining cells with chemistry and art!
