a Potato
Balloons
·
chemical reaction/gas “stinky science”
§ Vinegar
and baking soda in bottle create gas which blows up balloon stretched over
bottle opening
o A
much slower way to inflate a balloon with gas: http://blogs.roanoke.com/botetourtview/2013/09/cloverdale-elementary-school-uses-scientific-method-and-a-banana-to-inflate-a-balloon/
·
Rockets (with straw)
o Same
as under straws above: http://childparenting.about.com/od/schoollearning/ss/science-fair-topic-ideas-physics_5.htm
·
Rocket powered cars
·
Sound amplifier-great for a station
·
Static electricity-positively and negatively
charged particles:
o
Evan-Moor Science Experiments, Volume 2 p. 48 “Springtime Science”
§ Optional addition to first experiment-tissue paper
butterfly which the negatively charged balloon affects by making the wings of
the positively charged paper flutter up and down as the balloon is brought
toward and away from the butterfly
·
Air takes up
space:
o
kindergayle.files.wordpress.com/2012/01/air-huff-and-puff-trick3.doc
§ Balloon inside water bottle won’t be blown up
·
Warm air
rises:
§ Balloon,
bottle, ice water in bowl, hot water in bowl-air in bottle will warm, rise and
fill balloon (after being in ice water first effect is dramatic)
·
Screaming Balloons
Food coloring and/or watercolor markers (see individual
instructions for material)
·
Clouds and condensation:
·
Color mixing with milk-chemical bonds
·
Hot/cold water color mixing-molecule speed
·
Density and diffusion
§ ¾ jar
water, ¼ jar oil and a couple drops of food coloring in baby food jar-kid
experiment or have a few premade at a station—glue the lids on if at a station!
·
Absorption
·
Chromatography
·
Candy Chromatography
Paper and cardstock:
·
Air Pressure
§ Paper,
ruler-air pressure holds paper to table when ruler is hit
o http://www.stevespanglerscience.com/lab/experiments/heavy-newspaper-air-pressure-science-experiment
·
Air Pressure
§ 2
strips of paper to illustrate air moves from area of high pressure to area of
low pressure
·
Weight affects spin speed of objects Let’s do this one in the workshop!
o
Evan-Moor Science Experiments, Volume 2 p. 63 “Super Bunny”
§ Which of four objects makes Super Bunny spin the fastest?
·
Color Mixing
Wheel
o
Water:
·
Air pressure and water surface tension
·
Refraction
o
http://scientificteacher.com/2011/09/02/bent-out-of-shape-over-refraction/
-good tips on helping kids understand refraction
·
Cohesion and Adhesion
§ With a toothpick, pull a drop of water along a wax paper
covered maze
·
Surface
tension
§ Pennies added to cup of water (could use bowl) to break
surface tension as well as other experiments related to surface tension. Great explanation of surface tension and
surfactants, etc.
·
water density and temperature
o
Evan-Moor Science Experiments, Volume 2 p. 36“Plip, Plop, Drip, Drop”
§ Procedure: “Fill a glass bowl with warm water. Fill a small bottle with cold water and add a
little food coloring. Hold the bottle
sideways and lower it into the warm water.
Take away your thumb and watch what happens!”
§ Explanation: “The cold water will sink to the bottom
because it is “heavier” (more dense) than the warm water. The molecules in cold water are tightly
compacted so it appears to be heavier.
Warm water molecules expand and therefore seem “lighter.”

Tornadoes in
a Bottle

meteorologist for kids and parents/teachers

--experiment
Miscellaneous materials:
·
Inertia
§ Playing
card, penny and cup-flick card, penny falls into cup
o

--look for #35 of these 101 hands-on science
experiments-DEMONSTRATION ONLY for primary grades!
§ Bottle
with cork, vinegar, baking soda-demonstrate Newton’s Third Law of Motion- for
every action there is an equal and opposite reaction
·
Fire needs oxygen
o
Evan-Moor Science Experiments, Volume 1 p. 45
“Festival of Lights”
§ Pie plate, sand, votive, 3 different glass jars
·
2 substances
can combine to form a new substance
§ Salt and vinegar = hydrochloric acid and will cause oxygen
atoms from dull pennies to join the acid and leave copper pennies shiny.
·
Sound (vocal
chords produce sound with air as the travel medium)
§ Closed mouth humming is stopped when nose is pinched (no
air flow over vocal chords)
·
Air expands
when heated and contracts when cooled-demonstration only
§ Peeled, hard boiled egg, bottle, lighted piece of
paper-contracting air creates a vacuum and sucks the egg into the bottle
§ Reverse the egg in the bottle by adding air and increasing
the air pressure, causing the egg to pop out of the upside down bottle
§ Also includes instructions for doing same experiment with
a water balloon
·
Non-Newtonian
fluid
o http://www.scientiareview.org/pdfs/43.pdf see p 58 of this
document prepared to align with the MA Elementary Science and
Technology/Engineering Curriculum Frameworks
§ Ooblek
with cornstarch and water http://www.stevespanglerscience.com/lab/experiments/quicksand-goo

Screaming Cups – can also be decorated to look
like a bird
