ROBOTICS of Stars and Chemicals

What process needs to happen for a new substance to be created?

• Mixing

• Chemical Reaction

• Timing

What is the function of the AND logic block in this system?

• It turns the light red or yellow

• It turns the system on and off

• It means that when both Key Press blocks are pressed, the RGB LED will turn orange

Neither result in a new substance.

• The new substance created

• The combination of substances

• The first substance is cornstarch 

How do OR logic blocks function?

• They enforce that one ‘true’ input is needed to activate the output

• They enforce that two ‘true’ inputs are needed to activate the output

• They enforce that two ‘false’ inputs are needed to activate the output

Constellation is a group of stars that form a pattern

• True

• False

The Number blocks in the system of seasonal stars function to ensure the system stays on.

• True

• False

The appearance of stars is the same in both summer and winter

• True

• False

The cooler temperature means the air cannot hold as much moisture as in the summer, so the sky appears clearer in Winter (Northern Hemisphere)

• True

• False

Only a chemical reaction results in a new substance; mixtures do not.

• True

• False

What is the process by which two or more substances combine to form a new substance with different properties?

• Sublimation

• Evaporation

• Dissolution

• Chemical reaction
