Just kidding- this is another living systems question: (The rest are mixtures and solutions)
Give 3 examples of Biotic (living) and Abiotic (non living) factors in an ecosystem.
Biotic - Animals, bugs, decomposers, plants
Abiotic- Rocks, soil, light, temperature, water

Define photosynthesis
Photosynthesis is the process plants go through to convert sunlight, air and water into food.
100
What direction will shadows point at sunrise? (opposite of the sun)
When is the longest and shortest shadow?
Why do shadows lengths change during the day?
Shadow will start West and long, get shorter until midday and then proceed to get longer as it heads East. Shadows are caused by the Earth's rotation

The stages of the scientific method...
300
In science we write in what format?
What does each letter stand for and include?
CER
C- Claim- Restate the question and add your brief answer.
E- Evidence- Use lab data numbers, visible observations, but do NOT explain the relevance yet.
R- Reasoning- Explain what the data means and why it proves that you are correct.
400
How are landforms created?
Landforms: Created at plate boundaries (tectonic plates), including mountain ranges, ocean trenches, and volcanoes.
400
Physical VS Chemical Properties
What is the difference and give 2 examples of each.
400
Draw and explain a Food WEB. with the energy flowing in the correct direction.
What is the difference between a web and a chain?
Start with a producer, go to herbivores or an omnivore, and eat by an omnivore or carnivore.
If a decomposer is included, it can be at the top/and everything can be eaten by it.
Food chain has 1 line of energy, food web shows all of the consumers that share food sources.
400
Define conduction and convection
Conduction is when heat is transferred from one side.
Convection is when heat circulates like in a convection oven with a fan or in a pot of water where hot water rises and cold water sinks.
400
What are the standard units of measurement?
What are the metric units of measurement?
inches, feet, yards,mile, ounces, pounds, teaspoon, tablespoon, cup, pint, quart, gallons
meters, grams, liters, (milli, centi, deci, __, deca,hecto, kilo)
400
Think Music:
Amplitude VS wavelength VS Pitch
Amplitude= loud vs soft (height/ power of wave)
Pitch= High vs Low
Wavelength= The distance between wave peaks.
500
What is the difference between weather and climate?
What are the steps of the Water Cycle:
Weather vs. Climate: Weather is the daily state of the atmosphere; Climate is the long-term observable pattern of weather in a region.
Water cycle- The continuous movement of water through evaporation, condensation, and precipitation.
500
Give an example of each:
Solution
Solute
Mixture
Solvent
Dilute
Concentrated
Solution- lemonade (powdered)
Solute- salt
Mixture- salad
Solvent- water
Dilute - BARELY ANY sugar in water, honey in water, salt in water
Concentrated- SUPER SUGARY koolaid

Compare Yeast, Plant, and Animal nutrition
Yeast nutrition
-Need warm water between 40-50c and sugar to activate it.
-It is single celled.
-It is dormant before activated. When it is too hot it is killed.
Plant Nutrition
-Needs CO2, water, and sunlight
-This creates the process called photosynthesis. O2 and glucose come out of photosynthesis.
-They make energy through cellular respiration using the made products to make CO2 water and energy for themselves
-Soil isn’t needed BUT does provide more nutrients.
-Over-watering plants is not good.
Animal/ Human Nutrition
-Consumers have different teeth that go along with what they eat. Saliva in the mouth breaks down food.
-Then the chewed bolus gets pushed down the esophagus into the stomach where the acid and enzymes liquify the food.
-From there it enters the small intestine which is where the capillaries in the villi take the nutrients and send them through the body. The left overs are sent to the large intestine where excess water is absorbed before it is sent to the excretory system to exit the body.
-Your liver and kidneys are used to break down fats and filter out toxins.
500
Weathering vs Erosion
List 2 non renewable and renewable resources.
Weathering breaks it into sediment, erosion takes it (wind, water, gravity)
non-renewable resources- gasoline, oil, coal
renewable- wind, hydropower, solar, thermal, biomass
500
Construct means:
Destruct means:
Construct means: to create
Destruct means: to destroy
500
Conservation of mass and example.
What does it mean to conserve mass?
The mass remains the same.
For example, water freezing, even though the volume expands, the weight stays the same.
If you put 5mL of salt into a cup of 25mL of water, you'll have 30mL total. After combining the products the mass is staying the same. (If you see a problem like this you will need to do math)
600
What is the difference between potential and kinetic energy?
Energy wise- what happens when two objects collide?
Energy Types: Kinetic (moving objects), Potential (stored energy), Heat, Sound, Light, and Electric.
Collisions: When objects collide, energy is transferred from one object to another and often produced as heat or sound.
600
Define:
atom
molecule / particle
AND
What are mass and volume?
You need both to find....____
Basic units of matter.
mass is the weight, volume is the space it takes up
You need both to find density
600
Structure & Survival:
-Name an internal AND external structure and function of an organism.
- What do sense receptors do?
- Variation in Inheritance means...?
What do Biodiversity and microbes mean?
- Structure & Function: The physical part of an organism (structure) and the job it performs (function).
- Internal vs. External: Animals use external structures (claws, fur) and internal structures (heart, lungs) for growth and survival.
-Senses: Sense receptors (eyes, ears, skin) gather information which is then perceived and stored as memory to influence future behavior.
-Inheritance: Small differences between individuals of the same organisms. Passing traits from parents to offspring.
-Microbes: Decomposers that break down matter.
-Biodiversity: The variety of life in a habitat. A change in one part (like an alpha predator dying) impacts the stability of the entire system.
600
Constellation facts:
Why are some constellations visible all year while others are not?
Give 1 example of both
The constellations above the sun will always be north of us and visible. the others are in closer proximity as we revolve around the sun.
All year- Ursa Minor & Major
Seasonal- any of the zodiac signs roughly 7 months after their birthday range.
