This activity continues the idea as to why objects sink or float using the mathematical formula density equals mass divided by volume.

In this chemistry experiment, students will learn the fundamentals of copper plating (without using electricity) and if desired, extend the activity using different variables.

This experiment is a lab activity in which students will learn how different liquids react when put together.

This activity is a classroom lab in which students investigate and observe three types of balloons to help identify the states of matter and their properties.

This is a short unit (including hands on activities) on polymers and plastics to expand our study of physical/chemical properties and changes.

In this fun hands-on activity, students will create two different polymers, similar to Flubber and Silly Putty, using Elmers glue, liquid laundry starch, and Borax. Students will then compare the properties of the two polymers.

This activity is a classroom investigation where student observe several properties of water; adhesion and cohesion. They will transfer this knowledge to predicting other materials that will have adhesion with water molecules.

This activity will give kindergartner the chance to see what happend when they paint an iodine solution over a lemon juice message. They get to make thier own invisible message!

This activity can be used to teach concepts how different densities of liquids can be layered and/or how the salinity of water affects the movement of ocean water.

This activity is a guided discovery where students make chemical mixtures using sodium, learn about the Periodic Table, view salt under a microscope, and have a final result of bath salts for the bathtub

This activity is an extension activity following a unit study on mixtures and solution. Students will use variables to create a unique cola formula and present their findings.

This Chemistry experiment investigates physical changes, solutions, supersaturated solutions, and states of matter.

This activity is an inquiry lesson where students learn how to accurately read a thermometer and then set up an investigation to compare the temperatures of different materials or locations.

In this activity, students investigate the properties of a heterogeneous mixture, trail mix, as if it were a contaminated soil sample near a construction site. This activity shows students that heterogeneous mixtures can be separated by physical means, and that when separated, all the parts will equal the whole.

This activity is a laboratory extension where students test and collect data on two kitchen materials in the categories of solubility, saturation, chemical reaction and weights. Thus, giving students opportunity to reinforce skills already learned.

Through three lessons and their four associated activities, students are introduced to concepts related to mixtures and solutions. Students consider how mixtures and solutions and atoms and molecules can influence new technologies developed by engineers. To begin, students explore the fundamentals of atoms and their structures. The building blocks of matter (protons, electrons, neutrons) are covered in detail. The next lesson examines the properties of elements and the periodic table one method of organization for the elements. The concepts of physical and chemical properties are also reviewed. Finally, the last lesson introduces the properties of mixtures and solutions. A comparison of different mixtures and solutions, their properties and their separation qualities are explored.

A fun lab experience with little extra prep or materials needed. Kids are amazed that 1+1 doesn't equal 2!

In this classroom guided inquiry lesson, students will complete a serious of tests using five different mystery powders. Student will develop hypotheses, make observations, and draw conclusions about what each powder is and the physical and chemical reactions that occur when heat, water, iodine, and vinegar are added to each substance.

Students are introduced to acids and bases, and the environmental problem of acid rain. They explore ways to use indicators to distinguish between acids and bases. Students also conduct a simple experiment to model and discuss the harmful effects of acid rain on our living and non-living environment, as well as how engineers address acid rain. In an associated literacy activity, students learn how persuasive techniques are used to develop an argument, and create an environmental case study.

Students will use science skills of observing, describing and measuring in the context of Making Ice Cream. Students will understand the concept that physical properties can change.
