Circuits
Describe an open circuit.
Not all of the parts of the circuit are connected. Energy cannot flow through the circuit.
What are the 5 forms of energy?
Mechanical, Electrical, Light, Thermal, Sound
What are the four forms of precipitation?
Rain, sleet, snow, hail
What causes shadows?
An object blocks light
What type of soil is dark brown and soft?
Potting Soil
Describe a closed circuit.
All of the parts of the circuit are connected.
Energy can flow through the circuit.
Give an example of mechanical energy.
Someone riding a bicycle.
Describe the process of evaporation.
The sun heats up water and turns it into a gas.
What time of day are shadows the shortest?
What type of soil retains the least amount of water?
(Potting soil, sand, gravel)
Gravel
Teacher will check answers.
Give an example of electrical energy.
A fan being plugged in.
Describe the process of condensation.
Water vapor cools and turns into a liquid. This creates clouds.
At what time of day are shadows the shortest?
12:00 pm (noon)
What type of soil retains water the best?
Potting Soil
Draw an open circuit.
Teacher will check answers.
Give an example of thermal energy.
A fire.
What causes precipitation?
Water droplets in clouds get to heavy for the cloud to hold then they fall to Earth.
What causes the seasons?
The tilt of the Earth's axis.
If you pour 50 mL of water over a sample of soil and 45 mL drains out, how much water did the soil retain?
Which type of soil is this most likely describing? (Potting soil, sand, gravel)
5 mL
Gravel
What type of materials would complete an open circuit?
Any type of metal (iron, copper, gold, steel, etc...)
Create a T-Chart with THERMAL insulators and conductors.
Insulators: cotton, plastic, wood
Conductors: glass, metal
What are the five parts of the water cycle?
collection, evaporation, condensation, precipitation, runoff
How often do moon phases repeat themselves?
Every 28 days or about one month.
What are the properties of soil that can be observed?
Texter, Color, Ability to retain water
