My group made a model of an animal cell. These are the different parts in it:

Peppermint- Mitochondria

Orange peppers- Golgi and Smooth E.R.

Red and small orange Pepper- Vacuole

Dark Reese’s puffs- Lysosomes

Light Reese’s puffs- Peroxisomes

Yellow pepper- Rough E.R.

Apple- Nucleolus, and nucleus

pepper seeds- secretory vessels

Crushed candy cane- centrosome

Graham crackers- Cytosol 

spaghetti(not in the photo)-micro and intermediate filaments

Density Lab

We have been working on density in science. Here is a question I am investigating.

Density Lab Blog Post:

1. Explain what you did in the density lab and explain why the property of density determines whether an object will sink or float.  Also explain how can an two objects of the same size have different densities.

If the density is higher than water’s density(1g/ml), the object will float and if the density is lower than water it will sink. Two objects of the same density can sink or float. For example: Diet Coke and Mountain Dew. The Mountain Dew sinks and the Diet Coke floats. This is because Diet Coke has no real sugar in it and Mountain Dew does have sugar in it. This means that things of the the same exact size and shape can be different densities because of the materials it is made of. For example, a pencil and a pen. A pen might float and a pencil might sink. They are almost the same size and shape but they are different densities.
