Specific gravity experiment: “Rainbow Juice”

[Science × Sweets] Rainbow Juice Using Liquid Density [At Home]

It’s a juice with a mysterious, rainbow-like look, where beautiful layers of color appear in a single glass.

The key is the amount of sugar added to each color, using differences in liquid density to build the layers.

You’ll make three colors—red, yellow, and blue—varying the sugar content, and pour them into the glass in order from heaviest to lightest.

While creating some blended transitions between layers, it’s important to pour slowly over the back of a spoon so the colors don’t mix completely.

As-is, it would just be sugar water, so I also recommend adding flavorings or similar ingredients to make it taste good.

Experiment on the action of flowing water

Kimie Gangi, 5th Grade Science: “The Work of Flowing Water and Its Relationship to Water Volume” — Experiment Methods and Results #EducationalContent

In fifth grade, I think you also learn in class about the work of flowing water, such as erosion, transportation, and deposition.

Let’s actually observe these processes through an experiment.

For the method, build a slope out of collected soil, make a channel for water, and run water through it.

Try observing how erosion, transportation, and deposition actually appear, whether these processes change depending on the amount of water, and whether the way they appear differs between a straight channel and a curved one.

Test various conditions and summarize your findings in a report.

Investigate the conditions required for seed germination

5th Grade Science: Conditions Required for Seed Germination

In fifth grade, students also learn about seed germination.

So let’s investigate, through experiments, the conditions necessary for seeds to germinate.

When examining which conditions are needed, you must conduct a controlled experiment: keep all other conditions the same and change only one condition for comparison.

Try various conditions to confirm what leads to germination.

You may have already learned about the conditions for germination in class; if so, this experiment would be a good way to review what you learned.

Research how to make a paper airplane fly farther

How to fold a paper airplane that flies 100 meters, paper airplane folding Guinness record

Summer vacation is fun, but the thing that always trips us up is the independent research project or craft assignment, right? We also have to do our other homework, and we’ve got to go out and play! So here’s a project you can finish in one day.

This is a paper airplane everyone knows well… but it’s one that flies straight and far.

By getting creative with how you fold it and how you throw it, you can make a paper airplane that’s a little different.

How about explaining, with diagrams and text, how you came up with your ideas?

Let’s take a photo with the magnifying glass camera.

[Camera using a magnifying glass] You can print photos on light-sensitive paper. Learn how photography works! It’s also great for summer vacation crafts and independent research projects! You might even start to understand focus, exposure, shutter speed, and sensitivity!

When you take photos, you probably use a smartphone or a digital camera, but you can actually make a camera with everyday materials.

Prepare an outer tube made of cardboard with a magnifying glass attached to its bottom, and an inner tube made from a milk carton with tracing paper attached to its bottom.

Insert the inner tube into the outer tube, and your camera is complete.

You can focus by moving the inner tube.

When taking a photo, first adjust the focus, then attach photosensitive paper to the tracing paper, fix the camera in place, and wait.

Take out the photosensitive paper and apply heat with an iron, and the image will appear.
