The American Chemical Society has stated: "To learn chemistry, students must directly manipulate chemicals, study their properties and reactions, and use laboratory equipment and modern laboratory instruments. Commercial laboratory manuals contain experiments that range from trivial those dumb measurement labs to challenging e. Some experiments serve little purpose other than busy work to illustrate a principle and leaves students asking "so, what? On the other hand, there are a lot of independent experiments developed by individuals and posted on the Internet that are on the cutting edge of today's research e.

Don't look for these in commercial manuals. Many school and university teachers tend to be dinosaurs and are reluctant to try something new and are slow to change.

Easy Chemistry Experiments to Do at Home

I am a firm believer in integrated lecture-laboratory classes and utilize a range of experiments, some traditional and some non-traditional, in my classes. Some experiments are intended as introductions to course topics, some are used to reinforce concepts taught in class, and some are investigations to accompany course material. Although I list most experiments on separate course pages for students to download, I am assembling many of those experiments on this page to make them easier to find on my website.

All the following are experiments used, written, or modified, by David A. There are additional laboratory experiments that can be found under Chem Courses and Information.

Quick links. It must be relatively creative in the sense that it can branch off of a previously completed experiment or a supported new one. It can be related to any chapter of IB HL. Some elements that are not permitted to be used are Alkali metals, strong bases and acids.

The topic must be connected to a real-life situation such as implications in the household. Some example of compounds that can be used are baking soda, vinegar, lemon juice, milk, soap, etc.

I would be very pleased if anyone can help me with this! Good Luck and Have fun with the experiment! We are working on our IAs in class and I am struggling to find an experiment that I can perform where I can measure the exact concentration of sodium in Gatorade to see if there is a difference between experimental sodium concentration and the labelled amount of sodium in Gatorade. Is this a valid chemistry experiment or is there a more realistic experiment I could perform using the conductivity of Gatorade?

Project Ideas.Chemistry is an experimental science that combines academic study with the acquisition of practical and investigational skills. It is often called the central science as chemical principles underpin both the physical environment in which we live and all biological systems.

Apart from being a subject worthy of study in its own right, chemistry is often a prerequisite for many other courses in higher education, such as medicine, biological science and environmental science.

Through studying a science subject students should become aware of how scientists work and communicate with each other. While the scientific method may take on a wide variety of forms, the emphasis on a practical approach. The sciences are taught practically. Students have opportunities to design investigations, collect data, develop manipulative skills, analyse results, collaborate with peers and evaluate and communicate their findings.

How to write a Level-7 Chem IA in 3 hours

The investigations may be laboratory based or they may make use of simulations and data bases. Students develop the skills to work independently on their own design, but also collegiately, including collaboration with schools in different regions, to mirror the way in which scientific research is conducted in the wider community. The external assessment of chemistry consists of three written papers. In paper 1 there are 30 at SL or 40 at HL multiple-choice questions.

Paper 3 has two sections; Section A contains one data-based question and several short-answer questions on experimental work on the core and AHL material at HL. Section B contains short-answer and extended-response questions from each of the four options. Much of this information is taken directly from the chemistry subject guide, available to all IB teachers on the programme resource centre. Learn more about chemistry in a DP workshop for teachers.

Chemistry Chemistry is an experimental science that combines academic study with the acquisition of practical and investigational skills. While there are core skills and activities common to both SL and HL, students at HL are required to study some topics in greater depth, to study additional topics and to study extension material of a more demanding nature in the options.

The distinction between SL and HL is one of breadth and depth. A practical approach to the course delivery is emphasised through the interdisciplinary group 4 project and a mixture of both short-term and long-term experiments and investigations.

This investigation may involve a hands-on approach, use of data-bases, modelling, simulation or a hybrid.

Chemistry IB IA ideas 2019-2020

Student work is internally assessed by the teacher and externally moderated by the IB.Color change chemistry experiments are interesting, visually appealing, and illustrate a wide range of chemical processes.

These chemical reactions are visible examples of chemical changes in matter. For example, color change experiments can show oxidation-reductionpH changes, temperatures changes, exothermic and endothermic reactions, stoichiometryand other important concepts.

Colors associated with holidays are popular, such as red-green for Christmas, and orange-black for Halloween. There's a colorful reaction for just about any occasion. The Oscillating Clock or Briggs-Rauscher reaction changes color from clear to amber to blue. The reaction cycles between colors for a few minutes, eventually turning blue-black. For example, you can use phenolphthalein indicator to make water appear to turn into blood or wine and back to water clear - red - clear.

Turn Water into Blood or Wine. Transition metal complexes produce brightly-colored chemical solutions. One nice demonstration of the effect is called the Olympic Rings. Clear solutions change color to make the symbolic colors of the Olympic Games. Make Olympic Rings with Chemistry. Alchemists try to turn elements and other substances into gold.

It's a fascinating color change reaction. Turn Water into "Liquid Gold".

Here's a fun color change project in which a solution is poured from a water glass into a wine glass, tumbler, and beer glass.

Pre-treating the glassware causes the solution to change to appear to go from water to wine to milk to beer. This set of reactions is perfect for a magic show as well as a chemistry demonstration. You can use household ingredients to observe color change chemistry. For example, red cabbage juice changes color in response to pH changes when it is mixed with other chemicals.

No dangerous chemicals are needed, plus you can use the juice to make homemade pH paper, which will change color when used to test home or lab chemicals. The classic 'blue bottle' color change reaction uses methylene blue in a reaction that changes color from clear to blue and back to blue. You can use a pH indicator solution to display a rainbow of colors.

All you need is the right indicator and either a glass tube containing indicator solution and a pH gradient or else a series of test tubes at different pH values.

Two indicators that work well for this color change are Universal Indicator and red cabbage juice. Make a pH Rainbow Wand.

The Old Nassau reaction is popular as a Halloween chemistry demonstration because the chemical solution changes from orange to black. The traditional form of the demonstration uses mercury chloride, so this reaction is not commonly seen anymore because the solution shouldn't be poured down the drain.

Try the Old Nassau Reaction. The "Hot and Cold Valentine" is a temperature dependent color change that goes from pink to colorless and back to pink. The reaction uses the common indicator phenolphthalein. The "Vanishing Valentine" uses a resazurin solution that starts out blue. After a matter of minutes, this solution becomes clear.

When the flask is swirled, the contents change to pink. The liquid again becomes colorless and can be cycled through the clear-to-pink cycle multiple times. You can use indigo carmine to prepare a solution that changes color from green to red, making an excellent Christmas chemistry demonstration.

The color of the solution can be cycled between green and red.Want to do science but don't have your own laboratory? Don't worry. This list of science activities will allow you to perform experiments and projects with materials you likely already have in your cupboards. You don't need esoteric chemicals and a lab to have a good time with chemistry. Yes, your average fourth-grader can make slimebut that doesn't mean it's any less fun when you're older. Making a borax snowflake is a crystal-growing project that is safe and easy enough for kids.

You can make shapes other than snowflakes, and you can color the crystals. The snowflakes sparkle really nicely. If you use these as Christmas decorations and store them, the borax is a natural insecticide and will help keep your long-term storage area pest-free.

If you make the volcano and find the eruption to be disappointing, substitute these ingredients. You can clean pennies, coat them with verdigris, and plate them with copper.

This project demonstrates several chemical processes, yet the materials are easy to find and the science is safe enough for kids.

But we're not talking about fire here; the heat of a normal light bulb is all that's required to darken the lettering. Fire is fun. Colored fire is even better. These additives are safe. They won't, in general, produce smoke that is any better or worse for you than normal wood smoke. Depending on what you add, the ashes will have a different elemental composition from a normal wood fire, but if you're burning trash or printed material, you have a similar result.

This is suitable for a home fire or campfire, plus most chemicals are found around the house even of non-chemists. Heavier liquids sink to the bottom, while lighter less dense liquids float on top. Science experiments can taste good! This cooking chemistry project potentially uses no dishes, so cleanup can be very easy. It happens so quickly that you can form crystal towers as you pour the liquid into a dish.

You can set a bill on fire, yet it won't burn. Are you brave enough to try it? All you need is a real bill. Exploring separation chemistry with coffee filter chromatography is a snap.

You can also devise a project comparing the separation you get using different brands of paper towels. Leaves from outdoors can provide pigments. Frozen spinach is another good choice.
