35 Essentials for
5th grade Science
Anthony Figueroa
1. Lab safety rules are to avoid injuries
2. Refraction is bending (eyeglasses and mag.
glass), reflection is bouncing (mirror)
vs
3. Sound vibrates
4. Metals conduct heat and electricity; plastic,
glass, and wood are insulators.
Hot handle
Spoon not hot
5. Tides occur twice per day. Moon’s gravity
causes tides.
6. Planet order: MVEMJSUNP; my very educated
mother just served us nine pies (I still like
Pluto)
7. Rotation = 24 hours = day and night
8. Revolution = 365 ¼ days = 1 year
9. Tilt causes seasons. No tilt = no seasons
10. Lane #1 on a race track is best because it is
shorter to run around the track in Lane#1.
Mercury goes around the Sun fastest, because
it is closer to the Sun (Lane #1). Earth is 3rd
fastest (lane #3)
11. Moon….light on the right, the moon is
getting bright
Waxing
Waning
12. Sun is the source of all energy and light on
Earth and it is in the middle of the solar
system.
13. Producers are plants and grass; Consumers
are wolves and frogs who eat stuff to get
energy. The sun is the source of all life.
14. Plants absorb sunlight, breathe in CO2, and
release O2 (photosynthesis)
15. Food chains show energy transferring from
one organism into another.
16. Inherited your born with a trait; Learned
behaviors are taught
Inherited
Learned
vs
17. Clay or play-dough is good for making a copy
of a fossil.
18. The oldest rock is on the bottom (bedrock).
Youngest rock on top (surface)
Youngest rock
Oldest rock
19. What you start with is what you end with.
Start with 10 grams of salt, end with 10 grams
of salt after evaporating it. The water
evaporates, not the salt.
What to do
1. Pour salt into one of the bowls
2. Pour 150ml of water into each bowl.
3. Stir the salt well
4. Put the two bowls at the same place where
it is well exposed. It is best if they are placed
under the sun.
Conclusion
When salt water is evaporated, the salt is left behind.
20. Mixtures are not chemically combined and
can be separated.
Flour and water
Markers
21. Solutions are a type of mixture that looks
the same throughout. Ex. Salt water, air, brass
copper + zinc = brass
Oxygen + Nitrogen + other gases = air
Salt + water = salt water
22. To separate the following: Sand can be
filtered through a sieve & salt water can be
evaporated
23. Iron is Magnetic. Use a magnet to separate
mixtures that are made of iron.
24. Liquid  gas is evaporation (boiling). Water
boils at 100 degrees Celsius
25. Condensation is in the clouds when water
vapor turns to liquid; precipitation is rain
falling
26. Weathering is breaking rocks down, Erosion
is moving them, & deposition is building up
Weathering: Processes that change the
characteristics of rocks on the Earth’s surface
Erosion:
The removal of weathered
rocks by the action of:
–Water
–Wind
–Ice
–Gravity
27. The mouth of the river is the end of it
(where it flows into the ocean); a delta is a fan
shape of silt and clay at the end of the river
Nile river delta
28. Glaciers form valleys; rivers form canyons
(Colorado river formed the Grand Canyon)
Glacier-Valley
River-Canyon
29. Mass never changes. Weight does change.
So if you are the moon, your mass is the same,
but you do not weight the same.
Weight changes
(due to mass + gravity)
Mass doesn’t
change
30. Triple beam balance is for finding the mass.
Grams (g) and kilograms (kg) are the units
Mass of 195.5g
31. A Graduated cylinder is for finding volume of
a liquid. Liters (L) and milliliters (mL) are the
units. More accurate than beaker or flask.
32. There should only be one variable in an
experiment. Find it on the test and circle it.
Only 1 thing can be different
*pots same?
*seeds are same?
*soil same?
*amount of light same?
Only 1 thing can be different
33. Inexhaustible energy is energy man cannot
be “messed up” by humans: solar, tides, wind
34. Renewable is energy that will be there if we
take care of it: Trees, crops, meat from
animals, fresh air, fresh water
35. Nonrenewable is energy that Mother Nature
made once and only once: Fossil fuels (oil,
coal, natural gas) and minerals (gold).
