Mountains

Today in science we learned about mountains. You know if a mountain is old or young by the shape. young mountains are jagged at the top. old mountains are rounded at the top.

Did you know:
Some of the highest mountains are at the bottom of the sea.
Hawaii is at the top of a volcanic mountain in the Pacific Ocean.
More than half the mountain is below water.
The largest range of mountains is in the Atlantic Ocean.

Layers of the Earth

Today in science we learned about the different layers of the Earth. We had to put them in order and say if they were a solid, liquid, or gas. I learned that the core of the Earth is actually a solid and that the upper mantle just below the Earth's crust is liquid like taffy.

Mountains

Today in science we learned about mountains. There are 2 types of mountains.
1. Young mountains. They have jagged tops. They are newer and are still growing.
2. Old mountains. They have rounded tops due to erosion. They have been around for hundreds of years.

science

yesterday in science we were giving a map of the world. we had to post where earthquakes happened. we got the information from our text book. did you know that most earthquakes and volcanoes happen in the northern hemisphere?

science

yesterday in science we watched a bill nye the science guy video on caves. did you know that caves form in rock, water, or ice?

Solar Ovens

Tomorrow we are starting to work on our solar ovens. There are 3 ways to heat the s'more: radiation, convection, and conduction. Radiation is heating without touching the heat source. An example would be the sun. The sun can melt ice cream from a distance. Convection is heating with a liquid or a gas. An example would be a convection oven. The hot air rises to bake the food. Conduction is when the heat transfers through the object. An example would be touching a hot element. The heat transfers through your hand.

sience

in science on Monday we have to make solar ovens. Tomorrow we have to make the design of our oven. did you know that in 40 minutes the chocolate melted and the marsh mellow was soft.

science

Today we had a science test. it was on chapter 7 and 8. it was heat. did you know that temperature is the average movement of particals and heat is the total movement of particals?

Science

Today in science we are going to have a science test on chapter 7 and chapter 8. its on heat.

Heat

In science we are starting a new unit about how heat travels. Heat travels in waves that are invisible to the human eye. Heat can travel three ways: in radiation, convection, and conduction.

Radiation-Radiation is when heat travels through the air.

Convection-Convection is when heat is put directly onto an object.

Conduction-Conduction is when heat travels through an object to heat up another object.

Science

In Science we learned about temperatures and the effect it has on states of matter. (A state of matter is either a solid, liquid or gas.) Did you know that if the particles of an object heat up they expand and if they get cold they contract?

Science

Today in science we corrected a booklet on temperatures and thermometers. Did you know that the center of the sun is 15 000 000 degrees celsius? Also the first thermometer was invented by Galileo in the 1600's.

Thermometers

Today in science we learned what the difference is between a gas thermometer and a liquid thermometer. In a gas thermometer the liquid moves up and down because of the expansion and contraction of gas. In a liquid thermometer the liquid expands and contracts and that how you measure the temperature.

Energy

Today in science, we watched a video on energy. Stored energy is called potential energy. Movement energy is called kinetic energy. The types of energy are: movement, light, heat, electric, sound and chemical energy. Energy can be changed.
Ex: light energy can sometimes get hot and produce heat energy.
Chemical energy in us (food) can make us move and created movement energy.

Science

In science we learned about solutions. There are three types of solutions, the first is saturated solution, that solution can't hold anymore solute. The next is unsaturated solution, that can hold more solute. The last is super-saturated solution, that solution can hold more solute then it's supposed to.

Science

Today in science we did a project were you had to bring a stain, household remover, and a detergent. Then you had to see witch detergent or household remover cleans the stains best. Then you labeled what was what.

science

today in science we are doing stains. my group is doing laundry soap, lipstick, tooth paste and more. we have to wash them in the sink .

Solutions

Today in science we learned about solutions. A solute is a substance that dissolves into another substance. A solvent is a substance that dissolves other substances.

Science

today in science we watched a Bill Nye the science Guy video about chemical reactions. then we talked about it and then we talked about unit 5, chemical reaction and what they are.

Science Test

Today we had our science test. It was on matter, mixtures, pure substances and safety symbols. One thing we learned was:
Heterogeneous means that you can see the bits and pieces in the substance. Homogeneous means that all the pieces look the same.
