Observation of Rivers and Landforms

[Science] Landforms Created by Rivers and Their Functions

The actions of flowing water—erosion, transportation, and deposition—are expressed as landforms around rivers.

For example, deltas, which are often seen near river mouths, are landforms created by deposition.

Using the internet, books, or maps, investigate places where these landforms can be found, then visit them to observe directly.

If you take photos and also record surrounding conditions—such as the river’s shape and how the water flows—you may discover patterns you hadn’t noticed before and deepen your understanding of how flowing water works.

Origami Kaleidoscope

Origami: How to make an origami magic star fireworks kaleidoscope – kaleidoscope – origami kaleidoscope

As a topic for independent projects, making kaleidoscopes is popular, isn’t it? Here, let’s try a slightly unusual “origami kaleidoscope” that doesn’t use mirrors.

There are many steps, so it’s best for upper elementary grades, but if there are older siblings around, kids in the middle grades could give it a try too! The basic idea is to make lots of identical units and then assemble them.

You’ll need plenty of patience—and plenty of days to complete it.

When searching online, in addition to “origami kaleidoscope,” try “origami star” and “origami magic ball” as keywords.

Make a big kaleidoscope and amaze your friends!

transparent skeletal specimen

Transparent Seahorse Tube: Mysterious Charm ♡ Faux Transparent Skeletal Specimen

Here’s how to make a beautiful transparent skeletal “specimen” you’ll want to look at forever.

Draw the skeleton of a creature like a seahorse on shrink plastic using colored permanent markers.

Put the shrink plastic with the skeleton drawing into a microwave and heat it.

Once the plastic has shrunk, fill a jar tightly with store-bought deodorizing gel beads and set the shrunken piece in the center.

Then pour in purified water… the gel beads seem to disappear, and—like magic—the skeletal specimen appears to float.

It’s easy to make, so try it with creatures that have different kinds of skeletons!

Fun-to-shake shaker

Here’s a fun shaker made from a plastic wrap core.

Use origami made of film.

Wrap double-sided tape around the core and seal one end with the origami.

From the other side, add beads or similar fillings and seal it the same way with origami.

Wrap washi tape around it, then cut the origami into strips and wrap them on.

Add googly-eye stickers and a mouth to finish! It’s fun to dance with to music, too.

Little kids will enjoy it, so be sure to make it together and have a great time!

Maze ideas

You can make a fun maze with a cardboard wrap core! Here’s a simple way to do it.

First, cut construction paper to the length of the wrap core, and draw a maze on it using any writing tools you like.

Attach double-sided tape to the paper with the maze and wrap it around the core.

Next, cut a piece of wrapping film to about 5 cm and stick your favorite stickers on it—that’s it! Thread it through the wrap core to play the maze game.

If you make the construction paper removable, you can enjoy original mazes over and over again.

It’s also recommended to use stickers of your favorite characters to enjoy a themed world.

Fly! Core Rocket

http://www.lemon8-app.com

Here’s how to make an easy “core rocket.” You’ll need a plastic wrap core, a toilet paper core, two rubber bands, and a straw.

First, cut the straw so it’s just a little longer than the opening of the toilet paper core.

Link the two rubber bands by looping them together.

Tape the rubber bands to the straw, then tape the straw onto the plastic wrap core with cellophane tape.

Once it’s set up so the toilet paper core can be launched, you’re done! Decorate the toilet paper core however you like to make your own original rocket.

Have fun and get creative!

Making instruments with a plastic wrap core

No drill or cutter needed: Make instruments with a plastic wrap core [Crafts]

Let’s make a Chilean instrument that sounds like rain using a plastic wrap core! First, mark a bunch of toothpicks at the length of the wrap core so they match its length.

Next, cut the wrap core in a spiral.

Glue the cut toothpicks along the spiral using wood glue or similar adhesive.

Once you return the spiraled core to its original shape, seal the openings with duct tape.

Put in grains like mixed grains, different sizes of rice, beads, or beans.

After you cap it, your Chilean instrument, the rainstick, is complete!
