Watch the video below and read this tutorial for more information and ideas. Let us know in the comments below. This project used cassava starch as an effective component for a biodegradable plastic, but you could try using a few different starches and see what works best.
Watch the video below for more information and a complete walkthrough of their scientific process. But my problems are more superficial, like forgetting where I put my keys or what time my dentist appointment was supposed to be.
What is an inexpensive and easily accessible way to make produce stay fresh longer?
Making Biodegradable Plastic Plastic bags are actually illegal in Santa MonicaCA and soon to be Los Angeles because of their threat to the environment due to insane resistance to biodegradation. If not iodine is readily available, it can be chemically made either with sulfuric acid and alkali metal iodide or hydrochloric acid and hydroxide peroxide.
Your project could revolve Science lab ph 1 ip finding the best option, and testing out some of your own browning-prevention solutions to see if you can come up with a better one. But for your investigatory science project, you will want to come up with your own hypothesis based on that information and test it out.
But how does it work? Anything from a lemon to an applepotatoor even passion fruit will work. There are tons of studies on memory and memory loss that you can research.
What about drinking grape juice or sniffing rosemary? Make Homemade Glue from Milk With milk, white vinegar and baking soda, you can make your own glue right at home. So, creating a better biodegradable plastic bag would be a huge achievement. Make it an investigatory project by changing up the recipe and testing which results in the strongest glue.
Figure out what your hypotheses will be and follow along with this video for you own investigatory project. With the high prices of regular gasoline and diesel fuel, the possibility of creating a usable diesel fuel from household cooking oils is pretty exciting.
Can you create your own ice or cool drinks quickly by another method? An investigatory project is basically any science experiment where you start with an issue or problem and conduct research or an investigation to decide what you think the outcome will be.
Create Another Alternative Fuel Image via wonderhowto. Most science experiments performed, from elementary to high school students and all the way up to professional scientists, are investigatory projects.
Check out this clip from King of Random. Well, let the investigation begin. Making Soap Out of Guava Basic hygiene should be available to everyone, but what about people who live in areas without easy access to grocery stores or pharmacies? Can you truly affect the way you act and feel by simply changing your posture?
You can also find more information, as well as another way to perform the experiment, here. In order to combat this, researchers and doctors have begun infusing iodine into regular table salts.
This experiment looks to discover how to build the strongest paper bridge by varying how the pieces are held together. Used Cooking Oil as a Substitute for Diesel We all know how lucrative the oil business is, but what if the next huge innovation in oil was sitting right inside your kitchen cabinet?
These are the types of questions you may look to answer. Purifying Used Cooking Oil Speaking of oil, if you use it to cook, you know that a lot of it goes to waste. You can make a DIY battery with a few different types of fruits and vegetables.
There are various methods and materials you can use to slow down the ripening process, such as honey and lemon juice. Your project goal would be to research methods of filtration or purification and test it on cooking oils. Although creating diesel fuel out of cooking oils that will run a BMW may sound like a reach, it still makes for a great project.
This article contends that memory can be improved by looking at NSFW images or thinking of dirty associations. The harder and more intriguing the initial question is, the better the resulting investigation and experiment will be.
You could also try varying the ingredients to make it dry faster, or work on different materials wood vs. Solar Water Purification One of the biggest world problems is finding clean water.
While these researchers focused exclusively on chitosan coating on bananas, you can branch out no pun intended and try an assortment of other fruits, veggies and possible coating materials.Mettler Toledo InLab Expert Go-ISM IP67 pH Sensors Cable length: m Thermometers, pH Meters, Timers and Clocks Classroom Science Lab Equipment; Environmental Science; Physics Classroom; with integrated temperature probe, PEEK shaft, fixed cable and ISM.
