Learn why an oil spill is so devastating for wildlife and the ecosystem with this hands-on activity. Kids experiment to find the best way to clean up oil floating on water and rescue the animals affected by the spill.
Build simple model structures, then experiment to see how the actions of earthquakes affect them. Do research into what engineers and architects build in earthquake zones, then perform an experiment to see if you can improve on their findings.
The human body needs iron to be healthy, and many breakfast cereal boxes boast that they contain it. Conduct a 6th grade science fair project to find out if cereals really contain all the iron they say they do.
Use common household items to make old oxidized coins clean and shiny again in this simple chemistry experiment. Form a hypothesis about which method will work best, then do some research to explain the results.
Vitamin C might not immediately cure your cold, but it definitely has health benefits. Does orange juice really have the most vitamin C? Conduct an experiment using an iodine titration method to learn the answer.
This is a classic science activity for the classroom, but it works well for 6th grade science fair projects too. Form a hypothesis about the strongest type of bridge design, then build your own models to test it out.
The rockets used for space flight generally have more than one stage to give them the extra boost they need. This experiment uses balloons to model a two-stage rocket launch, teaching kids about the laws of motion.
Choosing a science fair project means finding a subject that really interests you and coming up with a unique question to answer. Use some of these 5th grade science fair project ideas to create a cool experiment all your own.
Soil erosion is a serious problem that can lead to natural disasters like landslides as well as causing problems for farmers, who lose valuable topsoil. Try this experiment to learn how plants help keep soil in place naturally, and change up the variables like soil composition or types of plants.
Settle an age-old debate with this 5th grade science fair project. Collect saliva from both humans and canines with cotton swabs and place each sample in labeled petri dishes. Check the bacterial colonies in each and compare the results.
Every kid loves LEGO bricks, so incorporate them into your 5th grade science activities! Challenge kids to design and build their own zip line. You can set the parameters, like distance and slope, then let students get to work.
Ball-run challenges are always fun, but this one has a twist. Your goal is to build a run that gets the ball to the bottom taking the longest time possible! This requires kids to think about friction, slopes, and other creative features.
Prove that hot air rises by using candles to spin a homemade pinwheel. Then experiment to see how the number of candles affects the spinning speed. (As always, make sure kids use fire under safe conditions.)
Learn about the value of solar energy by building an oven that cooks food without electricity. Enjoy your tasty treats while discussing ways we can harness the energy of the sun and why alternative energy sources are important. (Love edible science projects? Get more ideas here.)
To design a safe bridge that meets the needs of the community, engineers must understand the capabilities and limitations of the bridge. This project is great for budding 5th grade engineers as they simulate constructing a bridge that serves its purpose and keeps community members safe.
Every 5th grade science curriculum is different, but many include some common concepts. Learn about the states of matter, matter and its interactions, and energy science with these neat 5th grade activities.
Discover the science of sublimation by turning dry ice from a solid directly into a gas. Then play around with surface tension as the resulting vapor fills a giant bubble. This one is so cool to see in action!
This density demo is a little more complicated than other science projects, but the effects are spectacular. Slowly layer liquids like honey, dish soap, water, and rubbing alcohol in a glass. Your 5th grade science students will be amazed when the liquids float one on top of the other like magic (except it is really science).
This easy experiment uses hot and cold liquids and some food coloring to explore the thermal and kinetic energy that creates convection currents. Take things a step further and research how convection currents work in large bodies of water, like oceans.
This is the classic science experiment that helps you teach the reactions between acids and bases, plus what happens when you mix different substances together. Fill a bottle with vinegar and a balloon with baking soda. Fit the balloon over the top, shake the baking soda down into the vinegar, and watch the balloon inflate.
Kids love crystal projects, and this one results in winter decorations for your classroom. Your students will learn about supersaturated solutions and crystallization. (See more winter science activities here.)
This document appears to be a biology investigatory project on drug addiction completed by a student. It includes sections on the objective, classification of drugs, how addiction begins, effects of specific drugs like tobacco and alcohol, and conclusions. The project received guidance from the student's biology teacher and utilized several references in its completion.Read less
Welcome to WikiProject Biology, a WikiProject for discussing biology-related articles, editing issues, projects, and guidelines. The purpose of this project is to provide common ground for editors working in all biology-related projects, for seeking advice or requesting help from a broader community of biology editors, and for coordinating the categorization of biology articles. Please join us for discussion!
WikiProject Biology serves as a metaproject coordinating multiple subprojects. As a whole, WikiProject Biology and its subprojects maintain tens of thousands of articles, categories, templates, and other pages. However, WikiProject Biology itself only directly tags articles which pertain to the science of biology as a whole, which are relevant across many disciplines, or in some cases those which represent the field of biology as a whole to the public.
WikiProject Biology is a daughter project of WikiProject Science. We serve as a meta-project with several subprojects under our purview. The organization of these is presented below in a cladogram. WikiProject Molecular Biology is a proposed merger of WP:BIOP, WP:COMBIO, WP:GEN, and WP:MCB and their taskforces into a single project. This and other merges may change this diagram in the future. See discussion here.
Many biology categories are in bad shape. They tend to fill up with articles on minor topics that are better placed in subcategories (or sub-subcategories, etc.). A little maintenance of the top category and 30 subcategories would go a long way towards keeping articles properly sorted. These are listed below.

Biology is an important branch of science, it is the study of life, living things and the evolution of life. CBSE curriculum for class 12 includes investigatory biology projects which help the students to understand the fundamental theories. This blog will provide you with details on how to prepare a biology project for class 12 with some ideas topics and more.
It is important to monitor the chemical properties of the water we drink or use every day. The permissible pH of the water that is safe for our life and health is 6.5-8.5. If the pH is 3 to 5 it is too acidic for the survival of most organisms. Below the pH of 4.5, fishes die and only a small number of acid-tolerant insects survive. Likewise, a pH of more than 8.5 is too basic for the survival of most organisms.
Aim: Seed germination is affected by the pH of the germinating medium. The amount and type of various minerals and quantity and quality of humus control the pH in soils. A specific level of pH is required for different seeds for maximum germination. The level of pH also affects the growth and development, reproduction and metabolism activities of the plant.
Yeast is classified as a fungus and is made up of eukaryotic microbes, i.e, they have cells with nuclei. Fermentation is the process of breaking down a substance by bacteria, microorganisms or yeast. Yeast gets activated when mixed with sugar as it breaks down due to fermentation. Yeast alone or when mixed with water does not give any reaction.
Abstract: Sugar is a source of energy. When sugar is added to water while watering plants, the plants should grow healthier and stronger as they get additional energy from the sugar. This could be observed by visual inspection and measurement of plant samples with and without sugar for comparison.
Procedure: Soak the bean seed in separate cups containing- distilled water, hydrogen peroxide, malt, humic acid, potassium nitrate, and fish emulsion. Keep the seeds damn by placing them in between coffee filters. Record germination results over a period of 4 days.
Principle: Onion cells have 8 chromosomes. During cell division, the two strands of the DNA double helix separate, and for each original strand, a new complementary strand is produced, for the process of DNA replication. This is followed by the process of mitosis which assures that each daughter cell receives one copy of each of the replicated chromosomes. During this chromosomes pass through several stages of mitosis. These stages include interphase, prophase, metaphase, anaphase and telophase.
