What is Science? Science is when you work with animal and plant cells. It is also experimentation which is to explore.

In the real world, scientists... observe a lot. They take notes and share their findings..

In science class we... study about science. We studied about the great scientists and tried to recreate what they did only different. We did experiments as a group but Darwin did them alone.

The purpose of this site is... Communicate with friends or classmates far away. It is also to ask them if you need help or not and they can answer. It is also to share your experimenting results.

Lab safety 1st


 * Don’t reach over
 * Use tongs
 * Supervision when in use

This is my secret life....



Reflection on the the Viscosity Lab

media type="custom" key="10981772" width="70" height="70"

Metals take up most of the Periodic Table. At room temperature Mercury is the only metal that is in liquid form. The zigzag line represents the separation of the metals and non metals. The atomic number represents how many atoms are in each element. If an element has more atoms it’s weight increases. Sulfur is like chalk. It crumbles when it is hit with a hammer. It is a solid. There are metals in the T.V. The element led is in our pencils.

It's Elemental ! Part 1
 * 1) How many electrons surround the nucleus of an atom of Beryllium? Answer: 4
 * 2) How many electrons surround the nucleus of an atom of Helium? Answer: 2
 * 3) How many neutrons does an atom of Polonium have in it's nucleus? Answer: 125
 * 4) How many neutrons does an atom of Samarium have in it's nucleus? Answer: 88

Part 2 Name || # of Energy Levels || # of Valence Electrons || Property: Melting Point || Property: Boiling Point || Property: Density g/cm3 ||
 * Symbol || Element
 * Rb || rubidium || 5 || 38.89 ||  ||   ||   ||
 * Ca ||  ||   ||   ||   ||   ||   ||
 * Xe ||  ||   ||   ||   ||   ||   ||
 * Br ||  ||   ||   ||   ||   ||   ||

Alka Seltzer Lab

The purpose of the lab is to see if temperature rate effects the rate of a chemical reaction.

The vapor pressue (Hand Boiler) experiment: Vapor Pressure video

What is your prediction?
 * My prediction is: I think the ethanol is going to rise by my hot hand.
 * My second prediction is: It's going to come down again.

What is vapor pressure?
 * vapor pressure is defined as:air pressure.

How does vapor pressure affect a liquid or gas?
 * A liquid or gas is affected by vapor pressure by:air.

My observations for this really neat experiment are as follows: Popplet Activity:
 * 1) When the hand boiler is at rest, the ethanol is still.
 * 2) When I cup my hand around the bottom of the hand boiler, it rises.
 * 3) When I take my hand away from the bottom of the hand boiler, it falls.
 * 4) When I cup my hand on top of the hand boiler, I observed it slid downward.

The purpose of the cabbage lab is to turn the juice into a base.
