2. Check if its already been answered.
3. Look at how others did it

What is the difference between diet and nutrition?
Diet is what you eat
Nutrition looks at the food your body needs to function properly
Differentiate between data and information.
Data involves raw values that have no meaning. Information is organized data with meaning.
This variable is what the scientist changes or manipulates in an experiment.
Independent
Differentiate between simple and complex carbohydrates. Give an example of each.
S- Short chain molecules/Easy to Break down
C-Long chain molecules/Harder to Break down

Four of the Following: Observation and Inference, Prediction, Classifying,Measuring and Estimating, Communicating, Controlling Variables, Collecting, Representing, and Interpreting and Experimenting.
When testing the effect of study time on test scores, this is the variable that reflects the change.
Dependent Variable
What is the difference between vitamins and minerals?
Vitamins are organic molecules our bodies need in order to function appropriately.
Minerals are inorganic elements
What is the function of pancreas
Releases enzymatic juices and alkaline fluids.
In an experiment to see how different amounts of light affect fish behavior, the size of the tank and type of fish are examples of this.
Control Variable
Name each step of the Scientific Method in the correct order.
1. Observe/Problem/Question
2. Background Research.
3. Hypothesize
4. Experiment
5. Analyze Data and Draw Conclusions
6. Communicate Results/Report
Derrick has two snake plants, placed on the verandah at his home. He wondered what the effect of water would be on the plant. He watered one with two cups of water every week, and the other with half a cup of water every week. After a month, he notices that the plant watered with two cups of water has grown significantly taller than the one only watered with half a cup of water. What is the independent variable, dependent variable and TWO control variables.
D-Plant Height/Growth
ID-Amount of water
C-Soil, Plant Type
This helps to keep our digestive system healthy and is found in vegetables, grains, cereals, and fruits.
Fibre
List the FOUR major steps in the digestive process. Outline what each step involves
Ingestion-Take in food
Digestion-Breaking down of Food
Absorption-Absorbing of Nutrients
Egestion-Removal of Waste from Body
