For those of you joining me for the first time here's a little background on our current science activities. We are doing an in-depth cell study for science. Over the past seven months we have become familiar with many new words in conjunction with my daughter's Leukemia treatment. Some of which are; white blood cells, red blood cells, platelets, bone marrow biopsy, leukocytes, and neutraphils. With all this going on the timing was just right to study cells for science.
David Macaulay's The Way We Work is the fabulous resource we are using as a guide for our cell activities. Each week I read a few pages in the book and then create an activity to go along with what I read. This week the topic was Energy Breakdown.
Energy breakdown with cells is something like digestion. There are several steps to digestion. Food is smashed by chewing and broken down further in the stomach. It is broken down still further as it works its way through the digestive tract. Within the cells, energy breakdown also happens in several steps.
Glucose represented by crackers
Cytoplasm represented by marshmallows
Enzymes represented by marbles
Cells represented by empty soap bottles
ATP is the output or usable energy which is placed in the empty bowl
Mitochondria Inner Membrane represented by skinny plastic bag
Mitochondria Outer Membrane represented by plastic bag
The next step in energy breakdown happens in the mitochondria. The inner membrane is coiled inside the outer membrane.
When we finish up with cells we are moving into the rest of the human body. To see more of our cell and other science activities please visit the science page.
