You are looking through a high powered microscope. You see an atom. You count 12 positively charge, 10 neutral, and 11 negatively charged particles. Is something wrong? What and why?
What is YES! There are 12 protons and only 11 electrons. The number of protons and electrons is always the same!

Blood is a mixture of cells, platelets, and plasma. However, when you look at it, its just one color. Scientists can separate blood with a fast spinning device, called a centrifuge. Is blood heterogeneous or homogenous?
What is heterogeneous because blood can be separated into different parts, even though it looks all the same.

You are on a desert island and need something to drink. The only thing you have is salt water. How could you survive using the salt water, fire, and beaker (used to collect gas and liquids)?
What is "use evaporation to separate the salt and water. Then, use the beaker to collect the water vapor and let it cool / condense into pure water."
