Life Science
This is the smallest unit of a living organism and the basic building block of life
What is a cell?
These processes, such as the collision of tectonic plates, push the ground up to form features like the Himalayas.
What are constructive processes?
This type of change occurs when you mix pretzels, chocolate candy, and nuts to make a trail mix
What is a physical change?
This is the primary purpose of a battery in a simple electric circuit.
What is the power source?
The Mix-Up: You mix pretzels, chocolate candy, and nuts together for a snack. Because you can easily separate them again, this is an example of what kind of change?
What is physical change?
This structure is the "control center" that directs all of a cell's activities.
What is the nucleus?
This specific landform is often created by constructive processes like sand deposition from wind.
What is a sand dune?
This type of change is evidenced by bubbles forming when mixing baking soda and vinegar.
What is a chemical change?
This naturally occurring form of electricity is produced by electrical discharge in the atmosphere.
What is static electricity
Shocking Hair: If you rub a balloon on your head and your hair stands up, you have just demonstrated this "natural" type of electricity.
What is static electricity?
Unlike animal cells, plant cells have these two unique structures for support and making food.
What are the cell wall and chloroplasts?
This tool is used by scientists to record seismic waves and gather data on tectonic activity.
What is a seismograph?
This is the reason snow melts into a puddle when temperatures rise from 29F to 54F.
What is increasing temperature?
This type of material, like a metal wire, allows electricity to flow through it easily.
What is a conductor?
Mystery Bubbles: When you mix baking soda and vinegar, you see bubbles and the container starts to feel colder. These are clues that this kind of change is happening.
What is chemical change?
This tool uses a series of contrasting characteristics to help scientists identify specific organisms.
What is a dichotomous key?
In a meandering river model, this process typically happens on the inner bends of the river.
What is deposition?
This observation—a change in temperature—is a key indicator that this type of change has occurred.
What is a chemical change?
This is the correct step to take to test if a mystery material is an insulator or a conductor.
What is connecting the material to the open ends of the wires (if the bulb lights, it's a conductor)?
Growing Giants: Mount Everest and the rest of the Himalayas are actually getting taller by about 2.4 inches every year! Is this caused by a constructive or destructive process?
What is a constructive process? (Collision of tectonic plates)
These are behaviors that animals are born knowing how to do without being taught, such as a spider spinning a web
What is an instinct?
A student is building a model of a river. They notice that over time, the water carves a deeper path into the soil in one area and drops off sand and pebbles in another. Name the two specific processes occurring AND identify which one is destructive and which is constructive.
What are Erosion (destructive) and Deposition (constructive)?
If you take a 10g piece of paper and burn it completely, the remaining ash weighs only 2g. However, the Law of Conservation of Matter says matter cannot be created or destroyed. Explain where the "missing" 8g of matter went during this chemical change.
What is released into the air as gas and smoke? (The mass is still there, just in a different form).
You have a battery, a lightbulb, and three pieces of wire, but the circuit is open and the bulb won't light. Describe two different ways you could "close" the circuit to make the bulb turn on.
What are: 1. Connect the loose wire ends to each other; 2. Add a metal (conductor) object to bridge the gap; 3. Flip a switch to the "on" position?
The Particle Dance: To earn these points, your entire team must stand up and use your bodies to model the particles in a solid, a liquid, and a gas. Your teacher will call them out one by one!
