Question: what would be words that fall in this science experiment! please?

‘m doing a experiment on how long size D batteries last in flashlights and i need some words to look up that we have to put in our projects as “look up words.” Can anybody give me any?

Answer: battery, circuit, electrons, electrodes, alkaline, acid, charge, ampere, resistance, voltage, parallel, series, current, traditional current flow, filament, wasteful energy…etc.

Question: I’m having AP Biology problems!?

Okay, so I have some questions that I need help with for Advanced Placement (AP) Biology. I have some questions here and let me know if you know them.

1. Ecologists often use mathematical model and computer simulations because:

A. ecological experiments are always too broad in scope to be performed.
B. most of them are mathematicians.
C. Ecology is becoming a more descriptive science.
D. these approaches allow them to study the interactions of multiple variables and simulate large-scale experiments.
E. variables can be manipulated with computers but cannot be manipulated in field experiments.

and last one:

In which of the following biomes is light most likely to be a limiting factor?
A. desert
b. estuary
c. coral reef
d. grassland
e. ocean palagic zone

Answer: d. these approaches allow them to study the interactions of multiple variables and simulate large-scale experiments.

Question: what do you think would be a good science fair project?

hopefully something unique and interesting. The idea is due tomorrow, and unfortunately i am not very creative at the moment. I am interested in mostly botany and biology, so some experiment that has to do with plants and animals would be best (like trying to grow a plant upside down, or testing temp of water on fish color, something like that). Also geology and plate tectonics is ok too. ANy ideas? thanks!

Answer: Science Fair Project Ideas Google that right now, the most important thing you can do is hide your sources. Improve upon an interesting one you come upon and add your own unique touch.
