The experiments will be carried in a container stored in the crew compartment of the Orion capsule for the duration of the mission as it passes through the Van Allen Belts on the way out to the Moon and again on the way back to Earth. All specimens will be returned to the researchers for post-flight analyses after the spacecraft splashes down in the Pacific Ocean.
The field of biology offers a wide range of fascinating experiments that can deepen our understanding of the living world around us. From studying the behavior of cells to investigating the intricacies of ecosystems, biologists use a variety of methods to uncover the secrets of life.

Another easy to perform experiment for high school students is the yeast. This experiment is simple since all that is required is the removal of four different food samples onto separate plates and a thorough examination of the mold that develops on each sample over time.
The human tongue has specialized taste receptors that respond to five primary tastes: sweet, salty, sour, bitter, and umami (savory). Taste perception plays an important role in determining food preferences and dietary habits, as well as influencing the overall eating experience.
Bacteria are easily accessible and can be grown in a laboratory or even at home with simple equipment and materials. This makes it a practical and cost-effective experiment for schools with limited resources.
Light is a fundamental environmental factor that plays a crucial role in the growth and development of plants. By conducting this experiment, students can gain a deeper understanding of how light affects plant growth and why it is important.
Planaria regeneration allows students to design their own experiments, as they can choose which body parts to remove and study the effects of different variables, such as temperature, pH, or chemical treatments on the regeneration process.
Making a seed board can be a fun and engaging activity for students, as they can see the progress of their plants over time and share their results with others. It can also foster a sense of responsibility and ownership in caring for their plants.
Dissecting an owl pellet provides a hands-on learning experience for students, allowing them to practice skills in scientific observation, data collection, and analysis. Students can also learn about the anatomy of the prey species found in the owl pellet.
Growing an herb cutting provides a hands-on learning experience for students, allowing them to practice skills in plant care, experimental design, and data collection. Students can learn about the different stages of plant growth and the factors that affect it.
Creating an edible cell model connects to various disciplines, such as biology, anatomy, and nutrition. Students can learn about the different organelles that make up a cell and their functions, as well as the nutritional value of the food materials used in the model
Making a habitat diorama provides a hands-on learning experience for students, allowing them to practice skills in research, creative design, and presentation. Students can learn about different ecosystems and the organisms that inhabit them.
Creating a fall leaf (or signs of spring) journal provides a hands-on learning experience for students, allowing them to practice skills in observation, data collection, and analysis. Students can learn about the changes that occur in nature during the fall or spring season.
I'm planning a biology experiment I need to complete. I was planning on measuring the affect of pH on algae growth. I chose chlorella to be the test algae I use (are there any algae that would be easier to test?) and I have no idea how to measure the growth. My school does not have a spectophotometer, just basic biology and chemistry stuff. Also how can I change the pH of the water for my different samples? I'm a beginner and don't really have much experience so any help is appreciated!
For growth you could measure the mass of algae before and after the experiment. If you have a centrifuge you can pellet the cells or use a filter to remove the culture medium. Alternatively, if you have access to a hemocytometer and a microscope, you could get an accurate cell count that way.
For controlling pH, you'll need a buffer in your culture medium. You should select a buffer with a pKa close to the pH you want to test and then titrate the pH of the medium with a strong acid or base (HCl or NaOH). Make sure to check the pH before and after the experiment to be sure that it didn't change due to growth of the algae.
Get a bunch of jars or old soda bottles and in each one make a bunch of solution of the pH you want. So you will have a 2.5 stock bottle, a 3 stock bottle, a 4, a 5 on up. Then you can top up your algae grow jars as they dry out. Or better: pour out the old water and pour in new. Don't pour out your algae by accident.
Each algae grow jar is a 12 or 20 ml drinking water bottle. 3 bottles per pH level. Big number on each showing pH. Put them in a row in the sun. Change the water every 2 days. Take a photo every day.
Biology is fascinating, but not all of us have access to state-of-the-art laboratory equipment to do biology experiments. However, it is possible to do some simple experiments at home with the right materials. These DIY biology experiments are suitable for all ages and levels of knowledge. The main goal is to have fun with science and get curious.
In this video, you can find a step-by-step tutorial on how to make agar plates in your kitchen. Once you get some microbes to grow on the plates, you can experiment with how different conditions affect their growth or test the effect of antibiotics on the different microorganisms. (And if you have a DNA sequencer, you can use it to find which species are growing on your petri dish.)
For the creative souls out there, you can also make petri dish art by taking advantage of the different colors and textures of the different microbes you can find. Every year, the American Society for Microbiology runs a worldwide contest of agar art where you can submit your best creations.
There are many options to choose from, ranging from drinks such as kombucha, kefir, or mead, to yogurt, cheese, kimchi, and sauerkraut. In most cases, what you need is just a starter culture of the bacteria or fungi that make the food you will be fermenting. You can get it from someone that is already doing fermentation at home, or buy them online.
Each fermented food has different requirements, so make sure you have everything you need before starting. There are plenty of online tutorials you can follow, and once you get comfortable with the techniques, you can start playing with different conditions and starter ingredients to modify the taste and texture of your food.
The cells located at the tips of onion roots are also a very good subject of study. Whether you prepare and stain them yourself or you buy premade microscope slides, these cells are great to observe the different stages of mitosis and how the DNA gets duplicated and rearranged as the cells divide.
