Life Systems
These are three of the basic needs of plants
What is air, water, light, heat, nutrients, and space
This force pulls objects towards the Earth without touching them
What is gravity
This is something that holds up and has shapes and purpose
What is a structure
This is obsorbed by soil to help plants grow
What is water
How can we change the state of water?
The process of heating or cooling water can change it between solid, liquid and gas states
This part supports the plant and transports water and nutrients
What is the stem
This happens when you pull a wagon towards you
What is a pull
This is what a structure does, like holding people or objects
What is a function
This is when we take food scraps and natural waste such as fruit peels and let them break down into soil
What is composting
What makes a structure strong and stable?
These factors, such as shape, materials, and design, help structures stay strong and not collapse
Plants get thier energy from this source
What is the Sun
This a push or a pull that can make an object move
What is a force
Making the base wider is one way to improve this
What is stability
This is one of the two natural forces that are major causes of erosion
What is wind and water
What are some natural resources we use, and why should we conserve them?
These materials from Earth, like water, tree, and minerals, are used by humans and should be protected to ensure they are available for the future.
This is the process of a seed beginning to grow
What is germination
This type of force can cause damage during storms, like strong winds pushing objects
What is natural forces
Wood, metal, and plastics are examples of this when building a structure
What is materials
Helps soil become rich and full of nutrients while also reducing food waste
What is the benefit of composting
What is biodiversity, and why is it important for an ecosystem?
This term refers to the variety of living things in an ecosystem and explains why having many different species helps keep ecosystems healthy and balanced
This global issue caused by human activity can affect plant growth and survival
What is climate change
Enginers consider factors such as strength and stability when designing these
What is structures
Adding triangles to structures can help increase this
What is stability and strength
This type of soil is dark in colour, holds water, and is full of living things
What is healthy soil
Why is it important to protect our natural environment?
This explains why we need to care for nature to keep ecosystems healthy, protect living things, and ensure resources for the future
