This causes more bubbles to form, and soon they do not have anywhere to go but up, causing a soda fountain. Adults: Pour the peroxide into the bottles. After drying the initial components, NI3 forms, which is a very reactive compound. Learn about endothermic and exothermic reactions and energy exchange by experimenting with temperature change in chemical reactions. How long did it take for the reaction to occur? This is the simplest type of chemical reaction. The mixture should start to fizz and bubble which is a clue to the fact that a chemical reaction is happening, but have the kids keep their eye on the thermometer. I didn't find exactly what I was looking for (in my class, we have to design a lab experiment to test the rate of reaction, and I can't find a chemical reaction I can do), but this is overall an informative post. Cesium is one of the most reactive alkali metals. Not really much help I’d say. This is a physical change as water molecules vibrate faster, they enter the gas phase and become water vapor. The bubbles you see forming are a chemical reaction forming carbon dioxide. Then have them pour the yeast into the bottle with the peroxide and watch what happens! This science fair project idea examines which type of insulation holds in the most heat. Rocket balloons are a fun way to study the laws of motion, plus they use a safe propellant. You can design a middle school experiment exploring the effect of balloon size on the distance a rocket travels, whether the temperature of the air makes a difference, whether a helium balloon rocket and an air balloon rocket travel the same distance, and more. Shankar Ganesh Radhakrishnan from Chennai, India on May 25, 2015: Cool stuff, indeed! There are 4 main clues that a chemical change has occurred. The rate of evaporation does not affect final crystal size. sadie423 (author) from North Carolina on June 30, 2012: I hope you give them a try to that your kids enjoy them! Sadie has been an online writer for over six years. To Wrap or Not to Wrap? So, grab a glass dish and place a small pile of the sodium acetate powder from the pot in the center (This act as a seed for the crystals to start forming on). Sometimes chemical reactions can have an exciting end. There is a formation of gas which can be seen by a fizzing or bubbling, The reaction will cause heat, light or odor to be emitted, Leraner.com, "Physical Science: Session 4, A Closer Look: Chemical Vs. Tell them you are going to add a different liquid to each of the 3 tubes of colored water and they have to decide if a chemical change happens or not. Add a couple of these to your science lesson plans to help your middle schooler understand the science behind a … They kindly sent us some to try out and share here with you and I am excited to do so! Next we have an experiment that shows how a chemical reaction can produce heat. There is a lot of science to bubbles, too. Look at the sand mixture and the salt mixture. The Best Stain Remover for Clothes: Testing Laundry Stain Removal, Endothermic and Exothermic Reactions Experiment, Total Alkalinity and pH of Personal Care Products. Check out this fun science fair project idea to determine if the size of a particle affect the rate or speed of a chemical reaction. Were they right? This is fun experiment with a fun outcome so don't forget to let them play with the new substance for awhile! 3 test tubes with lids (or any container) filled half full with water, 3 containers: 1 containing bleach, 1 containing vinegar, 1 containing hydrogen peroxide. Ask them for any observations. Try the same filtering method with the sand water. Pour the peroxide into the bowl and place the thermometer in the liquid. thanks. Make sure to have an adult help you with this experiment. How do they know? Next up is the formation of a solid. i'am going to try these experiments with my kids at home this weekend and if they work well I demonstrate them at school. This is definitely a project for the outdoors, so you have less mess to clean up. In the cup, mix the water and yeast and stir for a few seconds to combine. Dr. Helmenstine holds a Ph.D. in biomedical sciences and is a science writer, educator, and consultant. When vinegar and baking soda mix, they form a chemical called sodium acetate. At that rate, we'd get in pretty big trouble with a lot of parents and teachers! Have them take one dropper full of the vinegar and add it to one of the colored tubes. And finally, here is an activity that can either be done as a demonstration or done by the kids on a smaller scale. These 10 completely awesome chemistry experiments will make anyone enjoy science. Crystals are good middle school experimental subjects. Like why is it changing colour etc. Middle school students like to perform experiments. 4 tablespoons of baking soda {sodium bicarbonate}, a glass measuring cup or mason jar {heat safe glass}. Doesn't explain what is happening. This science fair project idea sheds some "light" on which color of candles burn the longest. You can do some chemical reaction experiments in the classroom, with goggles and teacher supervision. Great hub. These types of experiments also increase practical life and fine motor skills. Science projects can be a lot of fun, even if you aren’t a science whiz. In another cup, stir a spoonful of salt into a half a cup of warm water. This experiment will demonstrate this simple concept to your students or children. Check out this cool science fair project idea to explore the relationship between pulse rate and blood pressure in healthy people. Such as when mixing sugar and water, the sugar appears to be no longer present so children assume a chemical change has happened when in reality the mixture can be separated back into its original substances. The last thing to look for when trying to tell the difference between and chemical and physical reaction is the occurrence of a color change. I mean it's pretty cool but I want something more advance, i will sure do this with my pupils. Set one nail aside for the control. 20 Science Experiments for Middle School Students. So funny and interesting. When it comes into contact with water, it reacts to form cesium hydroxide and hydrogen gas. Then have them stir while slowly pouring in the borax solution (this is a good 2 person job). Ashleyyyyyyyyyyyyyyy on January 25, 2018: I loved all the experiments and i would like to do all of them. Unsubscribe at any time. Kalaichelvi Panchalingam from PETALING JAYA on June 12, 2014: As a teacher I can say for sure that kids learn best by doing. Crystal Experiment ResourcesCrystal Science Fair ProjectsWhat Is a Crystal?How to Grow CrystalsHow to Make a Saturated SolutionCrystal Projects to Try. Don't worry, we still have lots of bubbles, fizzes, … Ask your children or students to guess why this has happened. Sometimes chemical reactions can have an exciting end. it's pretty cool but I want something more advance. It's called elephant toothpaste and it's even better than the exploding baking soda and vinegar. Students also experiment with density in the context of sinking and floating and look at substances on the molecular level to discover why one substance is more or less dense than another. This video should be taken down and the experiments performed with proper safety precautions. With easy science projects for elementary school students and more advanced chemistry science projects for older students, Education.com's science fair resource has what you need for an afternoon of fun science! Liked the elephant toothpaste part :) I'm sure gonna try and impress my 3 year old kid with these amazing experiments. Find out how to perform an experiment and get a hypothesis to test. There are several experiments you can design around this topic. Thanks! What happens to the water and the sand?
