STEM
The process that we use to investigate something in science.
The scientific process.
A group of different species living and interacting in the same habitat.
Community.
The Sun is a natural light source, but this everyday object is an example of an artificial light source.
Light bulb.
This is a push or pull that can make something move.
Force.
These are the remains or traces of plants and animals from long ago, often found in rocks.
Fossils.
Bikes use this type of system to make it move.
Gear system.
This shows how several food chains connect in one habitat.
Food web.
This type of object does not make its own light but lets you see it by bouncing light from another source.
Reflector.
This simple machine has a bar that moves on a fixed point and helps lift or move objects like a seesaw.
Lever.
Melted, liquid rock found beneath the Earth’s surface.
Magma.
A method people use to simulate real life conditions to help make predictions (e.g., creating an online food chain to see what happens if the relationships become out of balance).
Coding
For example, a polar bear’s thick fur helps it stay warm in cold climates.
Adaptation.
Light usually travels in this type of path unless it is reflected or refracted.
Straight line.
This type of motion happens when something spins, like a wheel or a fan.
Rotary Motion.
These naturally occurring solid materials make up rocks.
Minerals.
Before the creation of roads and highways, people used these parts of the natural land to travel from one point to another.
Rivers/lakes.
Planting trees and cleaning up litter are examples of this type of impact on habitats.
Positive impact.
Sound is made when objects do this, creating waves that travel through air or another medium.
This part of a machine helps transfer motion by connecting wheels, like on a bicycle.
Chain.
A rock that is formed by compressed sediment.
Sedimentary rock.
This type of water transportation allows travellers to pass through waterways without disturbing or upsetting the natural marine habitat.
Canoes/non-motorized boats.
When there is not enough food, water, or space, a habitat cannot support more organisms
Habitat limit/carrying capacity.
Streetlights help people see at night, but too many of them can cause this type of pollution that makes it hard to see the stars.
Light pollution.
This explains how machines can work easier by changing the size or direction of a force.
Mechanical Advantage.
Cooled lava on Earth’s surface turns into this type of rock.
Igneous rock.
