Perhaps no class is better suited to science experiments for high school kids than chemistry. Learn more: Genetically Modified Seeds/Science Buddies Let’s go green and see what happens when we pit our crops against some weeds! Will genetically modified plants come out on top or will the weeds reign supreme? Let’s find out in this exciting biotech and plant challenge! Explore the impact of genetic modification on seeds Let’s spice things up in the botanical kitchen! Mix up some “recipes” for your students’ plants by experimenting with different types of fertilizer and see which one they devour the most. Investigate the efficacy of types of fertilizer Learn more: Antiseptics and Disinfectants/Amy Brown Science 12. You’ll be able to see which ones effectively inhibit bacteria growth. Grow bacteria in a petri dish along with paper disks soaked in various antiseptics and disinfectants. Students will be amazed to see science theory become science reality right before their eyes. Look for cell mitosis in an onionĬell mitosis (division) is actually easy to see in action when you look at onion root tips under a microscope. Learn more: Carbon Cycle/Science Lessons That Rock 10. We know that plants take in carbon dioxide and give off oxygen, right? Well, this experiment helps you prove that and see the effect light has on the process. Learn more: Antibiotics Project/Home Science Tools 9. You can get a gram stain kit, bacillus cereus and rodospirillum rubrum cultures, and antibiotic discs from Home Science Tools. In this experiment, students first determine the two groups, then try the effects of various antibiotics on them. See the effects of antibiotics on bacteriaīacteria can be divided into two groups: gram-positive and gram-negative.
#Science experiments for middle schoolers how to
Show them how to observe an area over time, record their findings, and analyze the results. Teaching students to conduct field surveys opens up the possibility of lots of different science experiments for high school. Learn more: Taste Threshold/Science Buddies 7.
#Science experiments for middle schoolers series
Try this experiment to test subjects’ taste perceptions and thresholds using a series of diluted solutions. The sense of taste is fascinating-what some people think is delicious, others just can’t stand. Taste foods to find your threshold for sour, sweet, and bitter We’d all like to know the answer to this one: Is it really safe to eat food you’ve dropped on the floor? Design and conduct an experiment to find out (although we think we might already know the answer). Learn more: Phototropism/Science Buddies 5. So science experiments for high school students on this topic need to introduce variables into the process, like covering seedling parts with different materials to see the effects. Make plants move with lightīy high school age, kids know that many plants move toward sunlight, a process known as phototropism. Learn more: Mendel’s Pea Plants/Love to Know 4. Re-create his cross-pollination experiments with a variety of pea plants you’ve grown yourself. Gregor Mendel’s pea plant experiments were some of the first to explore inherited traits and genetics.
Learn more: Strawberry DNA/Numbers to Neurons 3. Turn this into a science fair project by trying it with other fruits and vegetables too. You don’t need a lot of supplies to perform this experiment, but it’s impressive nonetheless. Learn more: Potato Catalase/Practical Biology 2. Try this lab to isolate catalase from potatoes using hydrogen peroxide. Mash potatoes to learn about catalaseĬatalase is found in nearly all living cells, protecting them from oxidative damage. But there are plenty of other useful labs and hands-on projects for teens to try. When it comes to biology, science experiments for high school students usually bring dissection to mind. (Just a heads up, WeAreTeachers may collect a share of sales from the links on this page. That changes a classroom lab into a true scientific method experiment! Just consider variables that you can change up, like materials or other parameters. Many of these science experiments for high school are intended for classroom labs, but most can be adapted to become science fair projects too. Other projects involve fire, chemicals, or other materials they couldn’t use before. Some science experiments for high school are just advanced versions of simpler projects they did when they were younger, with detailed calculations or fewer instructions. The cool thing about high school science experiments and projects is that kids are old enough to tackle some pretty amazing concepts.
