Stomp Rocket Science: Free Lesson Plan and a Giveaway

After being cooped up all winter with textbooks and indoor activities, even moms get spring fever! With the sun starting to make its debut and the weather turning warmer, now is the perfect time to get out from behind those text books and get some hands-on science lessons outdoors.

Give Spring a Science Boost with Stomp Rockets

Maybe you remember Stomp Rockets as a kid, or you’ve seen them in the store? After all, they have been around for almost 25 years. If you have’t played with them yourself, you can tell it’s going to be fun, just from the name. Stomp Rockets!

Stomp Rocket Ultra LED is 100% KID powered: Run, jump and STOMP to launch these rockets up to 150 feet in the air! Click to turn on the powerful LED light inside, and these Stomp Rockets will really shine in the night sky, so it’s fun to play outdoors after dusk and on gloomy days too. Light up the night with vibrant color. The LED lights inside these rockets make them bright enough to double as a flashlight! Stomp Rocket Ultra LED is strong and durable, and great for active, outdoor play. Stomp Rockets have won lots of awards from industry experts, including iParenting Media, Dr. Toy and Creative Child Magazine. Includes a Stomp Launcher and 4 foam-tipped Ultra Stomp Rockets with bright LED lights inside. Refill rockets also available (item #20502). For kids ages 6 and up.

As if running, jumping, stomping and launching rockets into the air wasn’t just great all by itself, there are a TON of science experiments and concepts to learn from all of this fun.  Concepts include force, gravity, trajectory and so much more.

You can do a quick Google search to find some activities but did you know there is a corresponding curriculum you can use with your Stomp Rockets???

Use the “Stompin’ Science” book with Stomp Rocket Launch Sets to make science a blast! Kids can learn about things like gravity (what goes up must come down), trajectory, force and more by running, jumping and STOMPING to launch rockets — so learning is fun, interactive and active! Plus, the “Stompin’ Science” book makes teaching easy. It contains lessons for students of all ages and grade levels. Great for teachers, homeschoolers and parents who’d like to have some educational fun with their kids.

Here’s a peek at the lessons included in this book:

3 Fun Science Experiments Using Everyday Objects

everyday-science

Teaching science in your homeschool doesn’t need to be expensive or complicated.  (I can’t guarantee that it won’t be messy, though!)  With a few, simple, everyday objects from around the house you and your children can conduct these fun science experiments easily!

Click the “next” arrow for experiments to learn about gravity, static electricity and sound.  Get ready for some fun! Finger in the Bowl

goldfish-gravityConcept: Gravity

Does a bowl of water weigh more with a goldfish in it than it does without the fish?  This question usually provokes considerable argument.  What do you think the answer is?  If you said “Yes,” then you are correct!  The bowl’s weight is increased by exactly the weight of the fish inside.

Suppose you nearly poke a finger into the water.  Most people would guess that this would not make the bowl heavier, but it does.  The bowl’s weight is increased by the weight of the water your finger displaces, as you can easily demonstrate.

Place a glass on each end of a ruler, with a pencil beneath, to form a crude balance scale.  Adjust the pencil until the scale is almost, but not quite, balanced.  Now plunge your finger into the raised class, taking care to touch only the water.  The extra weight will immediately tip the “scale” the other way.

Unpepper the Salt

static-electricity-scienceConcept: Static Electricity

This is an amusing dinner-table stunt to show friends on dry winter days when static electricity is easy to produce.  Shake a pile of salt on a tablecloth, flatten it with your finger, then shake some pepper on top of it.  The problem is to remove the pepper from the salt.

Not many people are likely to think of the easy solution.  Just put a static charge on a pocket comb by running it a few times through your hair.  Bring one end of the comb to about an inch above the salt.  The grains of pepper, which are lighter than the salt grains, will jump to the comb!

Coat-Hanger Chimes

Big Ben at the Houses of Parliament, Westminster Palace, London, UKConcept: Sound

Tie the hook of a wire coat hanger to the center of a piece of string about five feet long.  Wrap one end of the string several times around your left index finger; then wrap the other end the same way around your right index finger.  Push the tips of both fingers into your ears.

Now bend forward and allow the hanger to strike against the side of a chair.  You’ll be startled to hear the sound like the chiming of an old-fashioned clock or church bell tolling in the distance.

The done is produced, of course, by the vibrations of the hanger.  The sound waves are transmitted to your eardrums via string and fingers!

There’s a much better way to teach kids aside from reading books. Here are 10 easy science experiments you can do with your kids today that they’ll definitely remember far longer compared to when they just read them from the books!

Click the “next” arrow for these 10 easy science experiments.  Get ready for great learning and some awesome fun!

Hard to Freeze

hard to freezePurpose

To determine the effect of dissolved nutrients on the freezing rate of water. How does this affect the freezing rate of plants?

Materials

  • 2 5-ounce (150 mL) paper cups
  • tap water
  • masking tape
  • marking pen
  • refrigerator
  • 1 teaspoon (5 mL) salt
  • spoon

Procedure

  1. Fill both cups with water. Use the tape and marking pen to label one salt water and the other water.
  2. Add the salt to the cup labeled salt water and stir.
  3. Place both cups in freezer.
  4. Observe the cups periodically for 12 hours.

Results

The salt water never freezes as hard as the pure water.

Why?

Salt lowers the freezing point of water. The pure water was able to freeze at a warmer temperature than the salty water. Plants freeze at different rates. Their surface area affects this, but it is also possible that the amount of dissolved nutrients in the cell fluid affects their resistance to the cold. Farmers find that bean, cucumber, eggplant, and tomato plants cannot stand even the lightest frost while plants like broccoli, brussel sprouts, cabbage and turnips can withstand heavy frosts. Some of these durable plants have large leaves. The materials dissolved in the leaves may help to make these plants more frost resistant.

Magic Solution

magic solutionsPurpose

To float an egg in a “magic solution”.

Materials

  • 2 clear, plastic cups
  • tap water
  • ¼ teaspoon (1.3 mL) milk
  • 3 tablespoons table salt
  • spoon
  • 2 small eggs

Caution: Always wash hands after touching an uncooked egg. It may contain harmful bacteria.

Procedure

  1. Fill both cups ¾ full with water.
  2. Add the milk to 1 cup of water. (This will be referred to as the magic solution.)
  3. Place an egg in each cup.

Result

The egg floats in the “magic solution” but floats in the milky solution.

NOTE: If the egg does not float in the magic solution, add more salt to the water.

Why?

The milk was added only to give the water a cloudy appearance like the “magic” salt water. The egg floats because it is not as dense as the salty water. The dense salt water is able to hold the egg up. The egg in the milky water is denser than the water; thus, it sinks.

Spheres of Oil

spheres of oilPurpose

To demonstrate that gravity has little effect on drops of oil submerged in a liquid.

Materials

  • ½ cup (125 mL) tap water
  • clear drinking glass
  • ½ cup (125 mL) rubbing alcohol
  • eyedropper
  • cooking oil

Procedure

  1. Pour the water into the glass.
  2. Tilt the glass and very slowly pour in the alcohol. Be careful not to shake the glass because the alcohol and water will mix. Caution: Do not get alcohol near your nose or mouth.
  3. Fill the eyedropper with the cooking oil.
  4. Place the tip of the dropper below the surface of the top alcohol layer and squeeze out several drops of oil.

Results

The alcohol forms a layer on top of the water.

Why?

The downward pull of gravity has little effect on the drops of oil because they are surrounded by liquid molecules that are pulling on them in all directions. The oil drops are also pulling on each other, and without the effects of gravity, the oil pull itself into a shape that takes up the least surface area, a sphere.

Pile Up

pile upPurpose

To demonstrate how sand dunes are formed.

Materials

  • shallow baking pan
  • flour
  • meat baster

Procedure

  1. Cover the bottom of the baking pan with a thin, flat layer of flour.
  2. Use your hand to support the baster with its open end about 2 inches (5 cm) from the edge of the flour.
  3. Squeeze the bulb of the baster 10 times.

Results

The flour moves away from the end of the baster in a semi-circular pattern. The flour piles up close to the end of the baster.

Why?

The moving air leaving the baster has kinetic energy (energy of motion). The flour particles are small enough to be lifted by the moving air and carried forward. Some of the smaller particles move farther away, but most lose energy and fall, forming a mound near the end of the baster. As this mound builds, it blocks the movement of even the smaller flour particles that would have traveled farther. This demonstrates how sand dunes are formed.

Snap!

snapPurpose

To demonstrate that an object remains stationary due to inertia.

Materials

  • scissors
  • ruler
  • typing paper
  • unopened can of soda

Procedure

  1. Cut a 4-inch X 10-inch (10 cm x 25 cm) strip of paper.
  2. Lay the paper strip on a clean, dry table.
  3. Place the soda can over one end of the paper. Note: Be sure that the bottom of the can is clean and dry.
  4. Hold the other end of the paper and push it close to the can.
  5. Quickly snap the paper away from the can in a straight line.

Results

If you pulled the paper quickly enough, it moved from under the can, but the can remained upright and in the same place.

Why?

Inertia is a resistance to any change in motion. An object that is stationary remains that way until some force causes it to move. The can is not attached to the paper. Because of the can’s inertia, it remains stationary even though the paper moves forward.

Bottle Organ

bottle organsPurpose

To demonstrate how frequency affects the pitch of sound.

Materials

  • tap water
  • 6 small-mouth bottles of comparable size
  • metal spoon

Procedure

  1. Pour different amounts of water in each bottle.
  2. Gently tap each bottle with the metal spoon.
  3. Note the difference in the pitch produced.

Results

The bottle with the most water has the lowest pitch.

Why?

Sounds are made by vibrating objects. The number of times the object vibrates – moves back and forth – is called the frequency of the sounds. As the frequency increases, the pitch of the sound gets higher. Tapping on the bottle causes the bottle and its content to vibrate. As the height of the water column increases, the pitch of the sound gets lower.

Bigger

bigger 2Purpose

To demonstrate how tiny water droplets in clouds grow into raindrops.

Materials

  • eyedropper
  • tap water
  • clear plastic lid (coffee can lid)
  • pencil

Procedure

  1. Fill the eyedropper with water.
  2. Hold the plastic lid in your hand, bottom side up.
  3. Squeeze as many separate drops of water as will fit on the lid.
  4. Quickly turn the lid over.
  5. Use the point of a pencil to move the tiny drops of water together.

Results

Some of the water falls when the lid is inverted, leaving small drops on the lid. The small drops combine, forming larger drops that eventually fall.

Why?

Water molecules have an attraction for each other. This attraction is due to the fact that each molecule has a positive and a negative side. The positive side of the molecule attracts the negative side of another molecule. The tiny water droplets on the plastic lid, as well as in clouds, join to form larger, heavier drops, which fall. The falling drops from clouds are called raindrops.

Soggy

soggyPurpose

To demonstrate how salt is used to measure humidity.

Materials

  • scissors
  • black construction paper
  • 2 saucers
  • teaspoon (5 mL)
  • table salt
  • pencil

Procedure

  1. Cut a piece of black construction paper to fit in the bottom of both saucers.
  2. Sprinkle ½ teaspoon (2.5 mL) of salt on the black paper in each saucer.
  3. Hold your mouth about 6 inches (15 cm) from one of the saucers.
  4. Exhale toward the salt in one saucer for about 2 minutes.
  5. Use the pencil to stir the salt in both saucers.

Results

The salt that was breathed on forms clumps when stirred, while the salt crystals on the other dish remain separate.

Why?

Exhaled breath contains water vapor. Table salt has a strong attraction for water and readily absorbs moisture from the air or your breath. The water causes the salt crystals to stick together. Air that contains a large amount of water causes salt to become soggy. You can tell the humidity is high when salt is difficult to shake from saltshakers.

Straight

straightPurpose

To demonstrate that light travels in a straight line.

Materials

  • scissors
  • ruler
  • cardboard
  • modeling clay
  • flashlight
  • index card

Procedure

  1. Cut three 6-inch (15 cm) squares from the cardboard.
  2. Cut 1-inch (2.5 cm) square notches from the center of one edge of each of the three cardboard squares.
  3. Use the clay to position the square about 4 inches (10 cm) apart with the notches aligned in a straight line.
  4. Lay the flashlight behind the column of cards.
  5. Use clay to position the index card like a screen at the other end of the column.
  6. Darken the room and observe any light pattern on the paper screen.
  7. Move the notches so that the notches are not in a straight line.
  8. Observe any light pattern on the paper screen.

Results

Light appears on the screen only when the notches are in a straight line with each other.

Why?

Light travels in a straight line. When the notches were in line, the light rays were able to pass through the openings, but when the notches were out of line, the rays were blocked by the cardboard.

See Through

see throughPurpose

To test the movement of light through different materials.

Materials

  • cardboard
  • wax paper
  • plastic sandwich bag

Procedure

  1. One by one, hold the plastic, wax paper, and cardboard pieces in front of your eyes while you note any differences in how objects in the room appear.

Results

There is little or no change in appearance when things are observed through plastic. The wax paper makes objects look dull and frosty, while nothing can be seen through the cardboard.

Why?

In order for you to see anything, light must be reflected from the object you are looking at to your eyes. The clear plastic is an example of a transparent material. Transparent means that light rays move straight through the materials and allow you to see objects as they are. Translucent materials, like wax paper, change the direction of the light rays that pass through. This change in direction makes objects look dull, frosty, and sometimes distorted. Cardboard is an opaque material – no light rays can pass through. Without light rays passing through to your eye, nothing on the opposite side of opaque materials can be seen.
