Samaury and her friends have taken a trip to the beach. All of these items were left in the sun for a couple of hours: a bottle of water, a bottle of sunscreen, a large beach towel and a couple of quarters. Which of these items will feel hot the quickest?
What is a couple of quarters? The quarters are metal, and metal is a good conductor of heat therefore they will feel hot faster.
100
Which of the following is not a form of energy: moving water, wind, sunlight OR oxygen
What is oxygen? Oxygen is not considered a form of energy, as it does not have the ability to do work.
100
Look at the following diagram. Which label shows the wavelength of the wave?
What is "A"? The wavelength of a wave is the distance from crest to crest, or trough to trough.
100
Which of the following need weathering and erosion to form? (igneous rocks, metamorphic rocks, sedimentary rocks OR mineral crystals)
What are sedimentary rocks?
100
What adaptation have birds in large cities made over time that affects humans? (Birds have adapted to make nests in unusual places on buildings where people live and work., Birds do not fly in the city and take up too much space on the road., Birds only eat from restaurant trash in the city., OR Birds fly less because of the pollution in cities.)
What is "Birds have adapted to make nests in unusual places on buildings where people live and work."?

Four metallic plates of different colors are placed in sunlight. Initial temperatures of the plates are the same. Which colored plate will have the maximum temperature after ten minutes? red, white, black OR green
What is black? black color absorbs the maximum amount of sunlight and this causes the black colored plate to become the hottest.
200
What type of energy gives the Sun its power and is also used to make electricity? (thermal energy, chemical energy, nuclear energy, gravitational energy)
What is nuclear energy? The Sun's energy is nuclear energy. Nuclear energy can also be used to generate electricity for us to use. Nuclear energy is released by either splitting the nucleus of an atom or combining the nuclei of two or more atoms.
200
Which of the following waves does the electromagnetic spectrum include? (ocean waves, light waves, stadium waves OR earthquake waves)
What are light waves? light is an electromagnetic wave.
200
Which of the following can also become trace evidence of prehistoric animals? (calls, voice, burrows, soft organs)
What are burrows? preserved footprints, trails, or burrows of prehistoric animals are trace fossils.
200
______ is the number of members of one species within an ecosystem or habitat. (Population, Community, Biodiversity, OR Niche)
What is Population?
300
As Kelvin heats up water for hot chocolate, the molecules __________________. (move slower, stop moving, move faster OR move in a straight line)
What is move faster? heat is created when molecules move back and forth, so the faster those molecules move, the hotter a substance becomes.
300
Energy can be transferred by ____________. (pushing a brick on a wall, running in place, pushing a wheel barrow, OR standing on a chair)
What is pushing a wheel barrow? Energy can be transferred by an event such as pushing a wheel barrow, which is the result of motion.
300
Light from the sun travels through a _________ to reach the Earth. (vacuum, solid, galaxy, OR liquid)
What is a vacuum? Space is a vacuum. Light can travel through space to reach Earth.
300
Look at the images of various rock layers with fossils. Which fossil is most likely the oldest?
What is a trilobite fossil? The rock layer containing a fossil provides information about a fossil's age. A trilobite is an extinct marine insect.
300
Why is it important to not pour oil, paint, or other chemicals into a storm drain? It is important to not pour oil, paint, or other chemicals into a storm drain because they ______. (stay in the drain for a long time, do not mix very well with fresh or salt water, will travel with storm water into river ecosystems, OR smell really bad in the drain)
What is "will travel with storm water into river ecosystems".
400
Rubbing two sticking together to create heat.
What is friction?
400
What type of energy does your body use to walk, run, and lift things? (chemical energy, light energy, mechanical energy OR nuclear energy)
What is chemical energy? Your body uses chemical energy from the food you eat.
400
Which of the following can light NOT travel through? (air, vacuum, water, OR mirror)
What is a mirror? Light can travel through space (a vacuum), air, and glass. Light is reflected off of a mirror.
400
What do rock layers tell us about fossils? (age, prey, predators, OR classification)
What is age? The rock layer containing a fossil provides information about a fossil's age
400
Which one is an example of a harmful change to an ecosystem? (reduce erosion, pollution, nutrient cycling, OR seed dispersal)
What is pollution?
500
Describe how a magnifying glass can be used to start a fire.
The magnifying glass can be held in a way to concentrate a ray of sunlight on a piece of wood or other flammable material. As the flammable material absorbs the sunlight, it would heat up & eventually catch on fire.
500
A battery provides _____ energy. When a battery is connected to a light bulb with wires, a closed circuit is formed. (potential, mechanical, electrical, OR circuit)
What is electrical? The battery is providing electrical energy. The electrical energy from the battery travels through the wires and makes the light bulb glow.
500
What property of light helps you see yourself in a smooth, flat, shiny mirror? (refraction, reflection, absorption, OR relativity)
What is reflection? It is correct because light waves are reflected by a smooth shiny surface.
500
What about the rock helps to determine a fossils age? (type of rock, location of the layer, minerals in the area OR chemical composition)
What is the location of the layer? The deeper the fossil location, the older the fossil is.
500
A deciduous forest has had a fire destroy half of the trees. Scientists have identified 87 grey squirrels that live in this forest. What will happen to the population of squirrels in this ecosystem? (stay the same, triple, double OR decrease)
What is decrease? The squirrel population will most likely decrease. Changes in an ecosystem’s food, water, or shelter determine the number in a species that can survive.
