There's A Hair in My Dirt
This book we read in science today tells of how Harriet (the cough cough lovely maiden cough) loves nature but does not understand it. She ends up killing many animals because of her stupidity and ends up dying because she touches a "cute little mouse" Humans should not interfere with nature unless we know for sure what we're doing. That way, we won't kill animals and plants by accident. -
Abiotic/biotic
Biotic means living, and abiotic means not living. Some abiotic things would be volcanoes, wind, rain, anything that didn't come from anything living. Biotic examples would be hair, animals, plants, finger nails, anything that is living or came from something living that can effect things. -
Venn Diagram
Today I made a venn diagram about what pork chops, steak, and snails had in common. I put that they all had food. -
atrophic level
Each time you move up a level in a food chain you lose ninety percent of energy to heat. -
Planet Earth: Mountain ecosystems
We did an assignment about the biome of mountain ecosystems. We watched Planet Earth and learned about different animals and their place in the ecosystem. -
Population
We made a map showing the classroom, and measured the room, found the area, and found how much space in meters each person had to themselves. Then we chose some limiting factors and how they effect the population. -
Physical Properties 1
Things that stand up and things that don't by themselves -
Chemical/physical properties
a clock is flammable -
What's Wind?
I think wind is a Physical property of air. -
How can you tell what chemical properties a substance has?
chemical properties can only be observed during a chemical change so you have to research and experiment to see the different chemical properties it has. -
Phase changes
a liquid changing into a solid is called freezing, and a solid changing into a liquid is called melting. A liquid changing into a gas is called evaporation. A gas changing into a liquid is called deposition. -
physical and chemical changes
physical changes don't create new substances and they can be reversed. Chemical changes create new substances and aren't easily reversed. -
physical changes lab
Iodine with baking soda equals baby poop. Iodine and cornstarch looks like crushed oreos. vinegar and baking soda fizzes a lot. -
Atoms
Atoms have some electrons in them and they go so fast they make a shell around the nucleus. -
Atomic Structure
There must be more positively charged particles in the atom than negatively charged particles. -
isotopes and ions
what particle determines an ion- an electron makes it ionic. what determines an isotope- a neutron makes it isotopic. -
Periodic Table
What do the columns and rows represent on the table?
Columns: silimar elements
Rows: how many orbitals they have.
