density: 0.534 g·cm⁻³

Neutral Boron Atom

2. the degree to which something is filled, crowded, or occupied. d=m/v
3.What did you discover in this simulation about putting an object in water versus putting the object in oil?

If you put the object into the water versus the oil, the object floated higher up and the object was lighter. If it was in the oil, the object sank down further.

Tell me two (2) other things you discovered while using this simulation.

-the brick floated to the bottom no matter if it was oil or water.

-the simulation explained the water level and how high it goes to when you drop it in oil or water. Oil had a higher water level number.

5.
4.1: When conducting science investigations,ask and answer questions that will help decide the general areas of science being addressed.
4.5: when studying a science-related problem, decide what changes over time are occuring or have occured
Standard B
4.1 Use encyclopedias, source books, texts, compuers, teachers, parents other adults, journals, popular press, and various other sources to help answer science related questions and plan investigations
Standard C
4.3 Select multiple sources of information to help answer questions selected for classroom investigations
4.4 Use simple science equipment safely and effectively, including rulers, balances, graduated cylinders, hand lenses, thermometers, and compuers, to collect data relevant to questions and investigations.
Standard D
4.3 Understand that substances can exist in different states-solid, liquid, gas
4.5 construct simple models of what is happening to materials and substances undergoing change, using simple instruments or tools to aid observations and collect data.
4.6 observe and describe physical events in objects at rest or in motion
4.7 observe and describe physical events involving objects and develop record-keeping systems to follow these events by measuring and describing changesin their properties, including: position relative to another object, motion over time, and position due to forces
