Science is not hard, its fun!!

(All at once)

Yeah science is hard!

This class is going to be so hard!

Hello class, I am Ms. Wentz. To start off the year we will be learning about cells. In this lesson you and I will be traveling to the inside of one of your classmate's skin cells. Jaden, can we use your skin?

Umm, I guess so....

To enter the cell, the kids and Ms. Wentz file into the bus, and Ms. Wentz activates her special lazer that shrinks them all into the cell. Jaden asks a scientific question.

What holds a cell together?

A cell is held together by the cell membrane. The cell membrane is a semipermeable membrane that controls what enters and wha exits a cell.

What is that blob thing in the middle of the cell?

That's correct Andrea! Great job!

I know, I know! That's the nucleus. It is the organelle what codes for all of the characteristics and functions of the cell. All organelles have specific functions that support the cell's use of energy.

The students exit the bus and explore the inside of the nucleus. Alex finds something interesting in the middle of the nucleus.

Oh my god, I actually know this one! Chromosomes are made up of genes that code for traits in an organism. They make up DNA!

Hey! What are these X shaped things?

Wow she actually knows something for once!

Haha so funny.

Ok class, we are now entering the mitochondria, also known as the powerhouse of the cell!

Why is it called the powerhouse of the cell?

It is called the powerhouse because this is where the energy that the cell uses is produced. The cell takes in the materials needed to make it's own energy, and then puts it in the mitochondria so that it can be transformed into useable energy.

So far we have entered the cell through the semipermeable membrane, seen chromosomes inside of the nucleus, watched the making of energy in the mitochondria, and now we are pulling up to the organelle called the endoplasmic reticulum. This organelle's function is- what's so funny?

The bus pulls up to the endoplasmic reticulum and Ms. Wentz is trying to tell the students the organelles function, but they are distracted.

WHAT ARE THOSE DOTS?!

Ohhh! Those are called ribosomes! These ribosomes produce protein that is packaged by the Golgi apparatus, which is where we're going next, and shipped out of the cell. Some ribosomes live in the cytoplasm and they also make protein, but that protein is used within the cell.

Irene asks a scientific question about the things the students are laughing about.
