This method of growing plants uses water and nutrients instead of soil.
Hydroponics
This is what you should always do before preparing or eating food to stop germs from spreading.
Wash your hands
What are the 3 basic needs of plants?
Nutrients, water, sunlight
This common ingredient helps bread rise by producing gas bubbles in the dough.
Yeast
This machine is commonly used to harvest crops like corn, soybeans, and wheat.
Combine
Plants grown hydroponically still need this process to make their own food using sunlight.
Photosynthesis
Keeping raw meat separate from fruits and vegetables helps prevent this type of contamination.
Cross contamination
This underground plant part absorbs water and nutrients for vegetable plants.
Roots
This ingredient gives bread its structure and is usually made from wheat.
Flour
This part of a plant is responsible for making food using sunlight.
Leaves
This important liquid carries nutrients to plant roots in a hydroponic system.
water (or nutrient solution)
This kitchen tool helps make sure foods like chicken and hamburger are cooked to a safe temperature.
food thermometer
Rotating where vegetables are planted each year helps prevent pests and improves this important growing material.
Soil health
This warm liquid is often added to bread dough to help activate yeast.
Warm water
This process of moving pollen from one flower to another helps plants produce fruits and seeds.
Pollination
One advantage of hydroponics is that plants often grow faster because they get nutrients delivered directly to this plant part.
Roots
This is the safe place to thaw frozen foods like meat or poultry to keep harmful bacteria from growing.
Refrigerator/cold water
Adding compost or manure to garden soil helps improve this by providing nutrients and helping soil hold water better.
Soil fertility
Kneading dough helps develop this protein that makes bread stretchy and chewy.
Gluten
This branch of agriculture focuses on managing forests and growing trees for products like lumber and paper.
Forestry
In some hydroponic systems, air stones or pumps are used to add bubbles into the nutrient solution to make sure plant roots receive enough of this essential gas needed for respiration.
Oxygen
Leftover food should usually be put into the refrigerator within this amount of time after cooking to stay safe to eat.
Two hours
This method of watering vegetable crops delivers water slowly and directly to plant roots through tubes or hoses, helping conserve water.
drip irrigation
When bread dough is left to rest and grow in size before baking, it is called this process.
Proofing
This farm practice adds nutrients back into the soil to help crops grow, often using compost or animal manure.
