- Grow a Butterfly. Students can gain knowledge about the various phases of development, from the egg to the larva to the pupa to the adult butterfly, by studying and taking care of a butterfly during its whole life cycle.
- Dissecting a Flower. Dissecting a flower can aid students in honing their analytical and observational skills. This may also aid in their comprehension of how a flower’s various components interact to facilitate reproduction, which is the flower’s main objective.
- Extracting a DNA. The extraction of DNA is an excellent experiment for high school students to gain a better understanding of the principles of molecular biology and genetics.
- Looking at Fingerprints. Exploring fingerprints can be a fun and intriguing experiment. This experiment encourages students to develop their problem-solving skills and attention to detail, as they must carefully analyze and compare the various fingerprint patterns.

In-person lab: Extracting DNA from Strawberries
This activity teaches students about the structure and function of DNA while also demonstrating how DNA can be isolated from cells. Students crush strawberries and use a lysis buffer to break down cell and nuclear membranes, releasing the DNA. The mixture is then filtered, and rubbing alcohol is added to precipitate the DNA, making it visible as a cloudy, stringy substance.
Virtual lab: DNA: Structure and Function
In the narrative of this virtual lab, students will work as an intern for a science magazine, Science Explained. One of the magazine’s readers has written a letter. They’re confused about DNA and have some questions about its structure and function. It’s their job to find out the answers and clear things up. They’ll get to learn how DNA is structured and how DNA’s code translates to functional molecules called proteins.
In-person experiment: Onion cell microscopy
This teaches students about cell structure and function using onion epidermal cells. Students prepare a wet mount slide with a thin layer of onion cells, stain them with iodine, and observe the cells under a microscope. It allows students to visualize plant cell components, such as the cell wall, cell membrane, and nucleus, while gaining experience with microscopy techniques.
Virtual lab: Meiosis, Mitosis and Plant Gametes
Students will use microscopy to study samples of lily anthers while helping the team at the laboratory. They’ll study the process of cell division and discover the key differences between meiosis and mitosis.
In-person lab: Diffusion and osmosis with eggs
Students use decalcified eggs (eggs soaked in vinegar to remove the shell) to study the processes of diffusion and osmosis. By immersing the eggs in various solutions, such as distilled water or corn syrup, students can observe changes in mass and size due to the movement of water across the semi-permeable membrane of the egg.
Virtual lab: Osmosis and Diffusion: Choose the right solution for an intravenous drip
In this virtual lab, students will help save Frank’s life by choosing the correct saline solution for an intravenous drip. He’s dehydrated because of sunstroke and needs extra fluids. They’ll join our virtual lab assistant in the lab to discover what a hypotonic, isotonic, and hypertonic solution is and how water is transported across the cell membrane in osmosis.
In-person lab:Photosynthesis and respiration in plants
Students use an aquatic plant, such as Elodea, and a dissolved oxygen probe or a simple inverted test tube setup to measure the rate of oxygen production during photosynthesis and consumption during cellular respiration. This experiment helps students understand the complementary processes of photosynthesis and cellular respiration in plants.
Virtual lab: Photosynthesis: Electron transport chain
To understand how photosynthesis works, students will shrink to a tiny size and go inside the plant cell of a leaf. Travel further inside the cell into the chloroplast, and then look at the thylakoid membrane. The process of photosynthesis takes place here. Observe the different components of the electron transport chain, from the start of the chain at photosystem II to the end of the chain at ATP synthase.
In-person experiment: Bacterial growth and antibiotic resistance
Students culture bacteria (e.g., E. coli) on agar plates and test the effectiveness of different antibiotics. They observe zones of inhibition, where bacterial growth is prevented, and learn about antibiotic resistance and the importance of proper antibiotic use.
Virtual lab: Gram Stain: How stains and counterstains work
Dive into the microscopic world and discover the colorful magic of the Gram staining procedure! Students will compare and contrast the cell wall of Gram-positive and Gram-negative bacteria by diving into their microscopic samples and observing how the cell wall structures retain certain reagents during the experiment. Discover how the four reagents of the Gram stain interact with structural components of the cell wall to color the bacteria.
In-person experiment: Monohybrid Cross and Mendelian Genetics
Students observe the results of monohybrid crosses involving a single trait. Using Punnett squares, students predict offspring ratios and compare them with observed outcomes from live organisms, such as pea plants or fruit flies. This activity helps students understand inheritance, dominant and recessive alleles, and how traits are passed from one generation to the next.
Virtual lab: Mendelian Inheritance: From genes to traits
Did you know that more than 99% of your genes are identical to those found in any other human being on the planet? In this simulation, students will learn how Mendel's postulates can be applied to determine how characteristics are inherited by being passed from one generation to the next. Are you excited by the idea of virtual labs? Check out our catalog of over 300 simulations and our free 30-day all-access educator’s pass.
- Extract DNA. Everyone knows DNA is the agent behind our hereditary traits. Residing in the cell’s nucleus, it guides major aspects of our physiognomy. Usually, the DNA is not visible to the naked eye, you need a powerful microscope to view it, but with this experiment, you can have a fine look at the DNA with this DNA extracting experiment.
- Dissect A Flower. Everyone has theoretically seen and known the different parts of a flower. Some exceptional students might even have that picture inscribed in their memory.
- Raise A Butterfly. Again, we have the theoretical knowledge of the life cycle of a butterfly. Yet it takes us by surprise and wonder when we see the process through our own eyes.
- Frog Dissection. Dissecting a frog is one of those lab activities that fascinate and chill you simultaneously. But before you start with the dissection, make sure you take note of all the outer organs like the skin, legs, head, digits, and urinary outlet (cloaca) of the specimen.
Water in Living Things – investigate how much water is stored in grass clippings. Gummi Bear Experiment – inquiry lab investigating the dissolving properties of gummi bears. Mystery Eggs – students use the scientific method to guess how many nails are hidden inside plastic eggs. Mystery Powder – containers with baking soda, corn starch ...
Summary. An experiment is a special type of scientific investigation that is performed under controlled conditions, usually in a laboratory. An experiment generally tests how one variable is affected by another. The sample size in an experiment directly affects the interpretation of the results.
