A student has to identify a material by calculating its density. The student was told that the sample of the material has a mass of 5.8 grams and a volume of .3mL.
What is the density of this material?
19.3 g/mL
Explain how to find the mass of an object.
In order to find the mass of an object you will need to use the triple beam balance.
Students will explain correctly how to use the triple beam balance.
Add up the mass.
What does it mean when an organism is heterotrophic?
Heterotrophic means that he organism has to eat other living things to survive, it can NOT make its own food.
What is a community?
Community is organisms of DIFFERENT species living together.
Element Si (Silicon) is a solid, shiny, semiconductor, and brittle. Is this a metal, nonmetal, or metalloid?
Metalloid
Students were asked to solve for the density of an unknown material. The mass was 5.6 grams and the volume was 3.5 mL.
What was the density of the unknown material?
1.6 g/mL
Explain how to find the volume of a solid.
First, you have to find the volume of the liquid, then add your solid to the graduated cylinder and find the new volume. In order to find the volume of just the solid you will need to subtract the after and before volume.
Why are plants considered autotrophic?
Plants are autotrophic because they can make their own food by the process of photosynthesis.
