the amount of space an object takes up.
What is volume?

Jakari takes a 8g carrot and chops it up to put into a stew. He chops it in 10 even slices. What is the mass of all the carrot pieces after it is chopped up?
What is 8g.

Shivani measures the mass and volume of 5 different glass marbles. Is this an example of repetition or replication?
What is repetition.
100
A gas condenses into a liquid. Describe the movement of the particles during this change.
What is the particles are slowing down.
200
Mass is 3 g. Volume is 10 mL. Will this substance sink or float in water (Water Density is 1 g/mL). D= mass/volume
What is float?
200
Extensive or Intensive: Electrical conductivity
What is intensive

When salt is added to water, the salt dissolves. Is this a physical change or chemical change?
What is physical change

Kelly and Matt, both cousins, get their grandmother's recipe for macaroni and cheese. They both go home and separately prepare the recipe. Is this an example of replication or repetition?
What is replication.

Draw a 2D model of the particles in a solid.
What is OOOOO OOOOO OOOOO

What is the bolt has the most density.
300
When zinc is added to water, nothing happens. But, when zinc is added to hydrochloric acid, it begins to sizzle and gives off a gas. Is zinc's reactivity to hydrochloric acid a physical or chemical property?
What is chemical property.

Rashawn vinegar and baking soda, and a reaction occurs. He massed both substances before the reaction, and the mass was 31.52 g. After the reaction, the mass was 30.6 g. Why is there less mass than before?
What is the mass was the gas that escaped into the air.

Which of the following is NOT a reason for scientists to replicate an experiment? A. to verify others's results B. to share their data with others who performed the same experiment C. to change their hypothesis if their results don't match. D. to make recommendations for changes in the procedure for future experimentations.
What is C.

If energy is continuously being added to a liquid, which of the following will NOT happen? A. It will turn into a gas B. Its temperature will decrease. C. Its particles will move more quickly. D. It will begin to boil
What is B

In the density lab, we calculated the density of glass marbles of different masses and volumes. This is the reason that the density of the marbles were the same.
What is they are made of the same material.

An extensive property is one that depends on the amount of matter, and intensive is one that does not depend on the amount of matter. Marissa adds sugar 1 tablespoon at a time. Each time, she notices that the sugar dissolves. After adding 10 tablespoons, she notices that the sugar starts collecting at the bottom. Is sugar's solubility an extensive or intensive property?
What is extensive.

Lilah lit her favorite strawberry-scented candle. The candle melted through contact with the heat. Is the candle going through a chemical or physical change?
What is physical change.

Antonio finds a meteor in a lake. Upon inspection of the meteor, he finds that there are microscopic multicellular organisms on the meteor. He also inspects other meteors he found in other areas and finds no organisms. He comes to the conclusion that life exists outside of Earth, and he wants to publish his findings right away. However, no editor is willing to publish his findings. Why not?
He needs others to replicate his experiment.

Andrea fills an ice tray with water and puts it in the freezer. What will happen to the kinetic energy of the particles of water?
Kinetic energy will decrease.
