This experiment is suitable for people of all ages. The algae and pollution experiment can be done with your entire family!
Algae is a natural feature of the pond ecosystem and grows naturally in ponds. Certain pollutants, on the other hand, can have an impact on algae growth. Phosphorus is one of the most critical elements for plant growth, but too much phosphorus in a pond, river, or lake can cause algae and other aquatic plants to grow out of control. They consume all of the oxygen in the water, suffocating other organisms such as frogs and fish. Another contaminant to be concerned about is acid rain. When the pH level in water is outside of the typical range, algae and other living organisms die.

Image Source/ Tutorial: Learning-Center Home Science Tool

Science can do a lot of things, including helping us comprehend our world, developing new technology, and even solving crimes! Forensic science is a branch of science that aids in the investigation of crimes.

All you need to do:

1. Leave prints on a microscope slide by touching it with your finger a few times. (If you want more visible prints, apply lotion to your hands.) To make cleanup easier, place the slide on a piece of paper before dusting.

2. Sprinkle a small amount of powder on the microscope slide, then gently wipe away the excess powder with the soft brush, taking care not to disturb the fingerprint. It can take some practice to get this just perfect.

4. Once you’ve mastered dusting a slide, go on to other surfaces such as doorknobs and faucets.

5. See whether any of the prints you make can be identified. To do so, take your family members’ prints and compare the known prints to the “mystery” prints. Color a few square inches of paper with a pencil, then have a family member wipe their finger around the square to pick up graphite, then press their finger against the sticky side of a piece of tape. Tape a white sheet of paper to the tape and write the name of the print on it.

Light Measuring Circuit Experiment For Students

 Light measuring Circuit Experiment For Students Science Fair Projects & Experiments for 8th Grade

Image Source/ Tutorial: Science Buddies

Using a light-emitting diode (LED) and a photoresistor, create an electronic color-detecting circuit. An LED is a little light that comes in a variety of colors. A photoresistor is a sort of resistor that is unique. Resistors are electronic components that prevent electrical current from flowing (their resistance is measured in ohms []). The resistance of a photoresistor is affected by light; it has a high resistance in darkness and reduces when exposed to light.
In this project, you’ll analyze how a photoresistor’s resistance varies when different color surfaces are illuminated with a red LED, and then use that data to design a circuit that can distinguish between red and green surfaces. Consider this the first step in creating a fully automated farming robot!

To use a liquid, soak paper or wood in it and let it dry before burning it, or pour the liquid into a shallow dish, let it evaporate, and collect the solid for use in crafts.

How to Write a Science Fair Project Abstract

We all know the Science Project abstract plays an important role in any science project fair. But do you know what an abstract means? And why it is so necessary to make an abstract? Before moving further, let me tell you what an abstract means?

Meaning of Abstract

The abbreviated version of the final report of your science project is known as abstract. Mostly science fairs put a word limit of up to 250 words. The science fair project abstract appears at the beginning of the report as well as on the display board.

These are the very important six pieces that most scientists and engineers agree that an abstract should have. These steps include:

1. Introduction

2. Motivate

3. Problem statement

4. Procedures

5. Results

6. Conclusion

Introduction: In this step, you have to describe the purpose for doing your science fair project or invention. This is a very important step as in this step you will tell your visitors, what special did you do in your project. You have to tell them what specialty does your project or invention contains, to attract the audience.

Motive: In this step, you have to motivate the reader to read the entire paper or display board so that they can understand your science project work more clearly.

Problem Statement: This step contains identifying the problem you solved, or the hypothesis you investigate.

Procedures: In this, you have to step out the approaches you’ve used to solve the problem. But don’t go into detail, unless they are critical to your success.

Result: In this step, you have to mention the result obtained. Do not use vague terms like “most “or “some”.

Conclusion: This is the final step, in this step you have to mention the science fair project or invention contribution to the area that you worked in, or did you get the desired result?

To make a good impact or for presenting your project in a proper way, the abstract is really important. Let us know why the abstract is so important.

Importance Of Abstract

A science fair project abstract helps people to quickly determine if they wanted to read the entire post or not. The Abstract also works as an advertisement for your project work. By working on an amazing abstract you can easily impress judges and the public about the science fair project.

An Abstract is always short, so it’s better to choose words wisely and convert the important message.

Meeting Up The Required Word Limit

Sometimes it’s hard to summarize a very long topic in a very short description. You should keep in mind to include all the key information. Just look for ways to make your abstract full of valuable information related to your work.

With the help of these guidelines, you will definitely create an amazing science fair project. So be ready to impress your target audience.

I hope that you had a great time reading and trying to make these Science Fair Projects & Experiments for 8th Grade. And if you want more ideas then read more posts and let me know which Science Project you like the most.
