Science Benchmark Skills Check

I was so excited to hear kids say, "My mom made me study!"

I was also asked by parents, "Are you going to make a science review?"

So here it is!

As promised, here is a review for the Science Benchmark that we will be having this week.

Vocabulary

-One of the most imperative things to know is the words increase and decrease. 

Science Safety

-Know science gear (goggle, lab coat, gloves) and why it is useful

-Know science tools such as beaker, thermometer, balance, etc.

Properties of Matter

-EVERYTHING is made up of matter.

-There are three states of matter- solid liquid and gas

-Solid-Have their own shape (know examples)

-Liquids- take the shape of their container and are easily poured (know

examples)

-Gas-fill their container, most times, they can not be seen (know examples)

-Water can be a solid (ice), liquid (water) and gas (steam)

-Know what happens when you increase and decrease the temperature of water.

**Classifying Matter (this ties into lots of the different topics we have learned)

-You can classify matter by shape, size, texture, flexibility, color, and temperature.

-Classify means to sort things

Changing Matter

-You can change the properties of matter such as shape color and size by doing things such as cutting, folding and bending them.  These changes are not permanent.

-If you mix beads and blocks in a bowl you can take them apart (reversible change of matter)

-If you mix flour, sugar, milk and eggs, and make cookies you can NOT take the ingredients apart (that’s an irreversible change)

Structures

-A structure I something that is made up of a number of parts that are held or put together in a particular way.

-Structures can be held together by tape, glue, etc. 

-Certain shapes can make structures stronger…like a triangle

-Twisting or folding can make a structure stronger also.

Light Energy

-Know the word dim.

-When you decrease light, things get dimmer.

-When light is dimmer it makes it harder to see.

-There is natural light (sun, fireflies, fire, stars) and man made light (light bulbs, flashlights)

Sound Energy

-Sounds are made by vibrations

-The vibrations make sound waves that travel to our ears

-Sounds can be loud (increase) or soft (decrease)

-You can change the way something sounds by moving further away from it or even by covering your ears.

-Ex. A car horn going off in the school parking lot, will not sound as loud if you are inside the school building.

-The pitch of a sound can be high (like a flute) or low (like a tuba)

Heat Energy

-Heat can be increased or decreased. 

-If you increase heat, properties of things can change:

-Candle wax can melt

-Water can boil

-If you decrease heat, things such as water can freeze into ice

Magnets

-Magnets are used in our everyday life

-Magnets attract (pull together) and repel (push away)

-Magnets have two poles (north and south)

-Opposite poles attract

-Magnets attract things made of metal (iron, steel, nickel)

-The earth acts as a magnet because of its iron core

Motion

-Friction can make heat by rubbing two things together

-Motion works by PUSH and PULL

-Gravity is a pull

-Different motions are: turn, twist, spin, slide, roll, etc.

Man...I never know how much we have learned until making these skill checks! We have learned so much this year already and still have another half of the year to go.
