Powering on Devices
In our lesson, we observed and compared these two types of clocks.
What is a wind-up and plug-in clock?
Energy from electricity travels through this type of pathway to power a device.
What is a circuit?
We created this model energy source on day 3.
What is a wind turbine?
Our Day 4 t-chart was divided into these two categories of energy sources.
What is renewable and non-renewable?
This energy source can be found in farms or on rooftops, which don't cause any pollution or toxic waste.
What is solar energy (or solar panels)?
This tells us that a digital clock is powered on when we see it.
What is the display lighting up?
A circuit must be this in order for electricity to flow and power a device.
What is closed?
Wind turbines are an example of this type of energy, which provide an endless supply.
What is renewable energy?
Our guest speaker discussed the use of this non-renewable energy source.
What is coal?
This connected all of the buildings in our green city.
What are power lines?
This is the main difference between how a wind-up clock and a plug-in clock are powered.
What is their energy source?
This can open or close the circuit to turn things on or off.
What is a switch?
A wind turbine needs this natural resource to generate electricity.
What is wind?
Solar, wind, and hydropower are all examples of this type of energy source because they can be naturally replenished.
What is renewable energy?
Burning coal and other fossil fuels releases gases into the air, causing this to the air.
What is air pollution?
When we observed the two clocks, we noticed the wind-up clock didn't need a cord because it gets its power from this.
What is being wound up (or mechanical energy)?
When we observed a broken circuit, the device stopped working because electricity could no longer do this.
What is travel or flow through the pathway?
Without these on a wind turbine, wind would have nothing to push against and no energy could be generated.
What are the blades?
Coal, crude oil, and natural gas are all non-renewable because once we use them, they cannot do this.
What is be replaced or reused?
While wind turbines are a clean energy source, they can negatively impact the environment by doing this.
What is harming bird populations?
This is why a plug-in clock feels warmer after being on all day as electricity is flowing through it to convert energy and raise the device's this.
What is temperature?
A complete circuit pathway is composed of these four components.
What are energy source, load, wires, and switch?
A wind turbine generates electricity by using wind to spin its blades, which turn this device that converts mechanical energy into electrical energy.
What is a generator?
This energy source is featured in the Dawn Dish Soap ad.
This helps fish migration and safe travel through the dam in hyropower.
What are fish ladders?
