  • Biotic and Abiotic

    We learned about ven diagrams and what the difference is between biotic and abiotic. Biotic things are things that are alive, and abiotic are things that are dead.

  • Biotic and Abiotic

    Today we made 3 circles each of different things. Then we talked about why these three things were alike, and put them in a google docs.

  • Trophic level

    The higher the consumer on the pyramid the less energy they can get.

  • Mountain Movie

    We learned about ecosystems all over the world. We also learned about how the environment affects ecosystems, and learned about some animals in their ecosystem.

  • We did a assigment on Populations

    We talked about populations and wrote down definitions and drew a map of our class on a google docs.

  • Usage assignment on canvas

    We did an assignment on the science book and did a google docs spreadsheet on the usage of things we used in a year and wrote it down.

  • Physical Properties 1

    Today we divided things up into metal, wood, glass, plastic, and wax.

  • Physical, chemical properties

    My object was a projector. a chemical prop. Is that it is probably not flammable, and if it was near a fire, it would melt. Because of the plastic.

  • Is windiness a Physical or Chemical Property

    I think it is a chemical prop. because their is a reaction in the air between cold air and hot air.

  • Physical and Chemical Properties

    How can you tell what chemical properties a substance has? If is is flamable or if it has reactivity with other substances

  • Phase change

    1. Ice cream melting is a physical change 2. A solid to a liquid is a physical change 3. cutting things

  • How do you tell the difference between gaseous physical and chemical change?

    Physical change only changes water to a gas. Chemical change, changes it to a gas, but has different characteristics. Like the smell would change and the color, and you couldn't reverse it so that would be a chemical change.

  • Physical and chemical changes

    I learned that that if you put iodine in cornstarch it turns black, looks thick and forms into spots in the cornstarch. I didn't know that would happen, so i thought it was interesting

  • Atoms

    I learned today that atoms have a nucleus and have a shell, and It also can transport through one thing to another.

  • Atomic Structure

    What is a rule for making a positive ion. You have to have more protons than neutrons or electrons for it to be positive.

  • What particle determines an Ion? Isotope?

    An electron determines an Ion, because it does not have a mass. An Nuetron determines an Isotope, because the charge stays nuetral, but changes the mass.

  • what do the columms on and rows represent on the periodic table?

    They represent the metals and not metals in the periodic table.
