Life Science (Biology)
Kahlil finds an object and wants to know if it is alive or not. He looks under the microscope and sees that it is not made of one or more cells. Can the object be alive?
No / Not Alive / Must be made of one or more cells to be alive
The mammoth’s huge teeth could grind the coarse grasses that grew in the cold climate. This helps scientists know that the wooly mammoth was well adapted to:
A warm climate
A dry climate
A cold climate
A tropical climate
A cold climate
The center of our solar system
What is the Sun?
The basic building block of life. In other words, all living things (organisms) are made of one or more of these.
What is a cell?
Members of this kingdom use light energy (the sun) to produce food through photosynthesis. Their cells have chloroplasts and a cell wall. They are multicellular.
A. Plantae (Plants)
B. Animalia (Animals)
C. Protista (Protists)
D. Fungi (Fungus)
Plantae (plants) Including grasses, trees, shrubs, aquatic plants, etc.
We looked at single-celled fungus called yeast under the microscope. Single-celled means:
Made of just one cell (bacteria/some fungi/most protists)
A change in which one or more substances combine or break apart to form a new substance.
Physical change
Chemical change
Chemical change (new substance is formed)
All existing matter and space considered as a whole (everything that exists) is called the
Solar system
Galaxy
Universe
The Universe
The traces or remains of a past life form. Types include trace, casts, and molds.
What are fossils?
These are known as decomposers as they break down and absorb food. They have chitin cell walls and most are multicellular.
A. Plantae (Plants)
B. Animalia (Animals)
C. Protista (Protists)
D. Fungi (Fungus)
Fungi (Fungus) Including yeast, mushrooms
Which is not a multicellular organism:
Human
Bacteria
Pine Tree
Lobster
Bacteria (only made of one cell)
Wegener found similar ____ of several different animals and plants that once lived on or near land had been found on widely separated _____. This evidence supported the idea that the plates have moved over long periods of time.
Plants; Mountains
Fossils; Continents
Fossils; Rock Layers
Fossils; Continents
(Fossils of non-swimming animals were found on continents separated by large oceans suggesting the land was once connected allowing animals to walk around, die, and become fossilized. After that, the land separated at the plate boundary and an ocean formed in between.)
Which of the following is an accurate model of how the Sun, Earth, and Moon move?
Sun and Moon orbit Earth
Earth and Moon orbit Sun
Earth orbits the Sun and the Moon orbits Earth
Earth and Sun orbit Moon
Earth orbits the Sun (about one year) and the Moon orbits Earth (about one month)
During a solar eclipse, the _____ comes between the Sun and Earth.
moon
ll members of this kingdom are multicellular. They get their energy from consuming/eating other organisms. Their cells do not have cell walls or chloroplasts.
A. Plantae (Plants)
B. Animalia (Animals)
C. Protista (Protists)
D. Fungi (Fungus)
Animalia (animals) Including fish, amphibians, reptiles, birds, mammals, insects, etc.
Which is not a life process that living things do?
Reproduce
Release wastes
Respond to the environment
Walk on two legs
Walk on two legs
(grow, get or make food, break down energy from food (cell respiration))
This hypothesis developed by Alfred Wegener proposed that Earth’s continents had once been joined as a single landmass that broke apart and sent the continents adrift.
What is
The Theory of Continental Drift
The Theory of Earth’s Plates
The Theory of Puzzle Fit
The Theory of Continental Drift

The amount of matter in an object (like its weight on Earth). We can measure this in grams by using a triple beam balance. Density = _____ / Volume.
Mass
All members of these TWO kingdoms are unicellular (made of one cell) and their cells do not have a nucleus. Examples are E. Coli, Staphylococcus, Streptococcus, and Methanobacteria. They break down materials in the ecosystem.
A. Archaebacteria (Ancient Bacteria)
B. Eubacteria (Bacteria)
C. Protista (Protists)
D. Fungi (Fungus)
Archaebacteria (ancient bacteria) and Eubacteria (bacteria)
Plants have additional cell parts such as chloroplasts because they need to ______
Photosynthesize or produce their own food
Reactions that release energy, usually in the form of heat (thermal energy) or light. Feels hot! Elephant’s toothpaste is an example.
Endothermic
Exothermic
Exothermic
A galaxy is a system of millions or billions of stars, together with gas and dust, held together by gravitational attraction. There are billions of galaxies in the universe! Name the galaxy that Earth is located in.
The Milky Way Galaxy is a spiral galaxy
Anything that has mass and takes up space (the stuff in the universe that we can touch and/or see). It can be solid, liquid, gas, or plasma.
Matter
Most are unicellular (made of one cell) and their cells have a nucleus. Some can make their own food and some consume food. Some members of this kingdom include algae, diatoms, and amoebas.
