Students examine how candles work and how scientific theories are developed and tested. Students propose hypotheses about what is burning in a candle then perform tests in order to develop their scientific theory. After a teacher...

Fourth graders experiment with the viscosity of different liquids. They use a stopwatch to time the a steel ball as it drops through different liquids.

Students complete calculations involving the structure and properties of matter. They engage in a variety of problem solving activities to help them determine the center of gravity.

Students examine how to apply conservation of energy and properties of matter to a spectroscope.  In this energy lesson students build their own spectroscope and observe three kinds of spectra.

Fifth graders relate the elements in the human body to those produced during a supernova. In this space science and chemistry lesson, 5th graders listen to a lecture and view visuals about the big bang. They relate the production of...

Alone, or as part of the intended unit on chemical reactions, this activity allows learners to experience an exothermic reaction. Here, learners add calcium chloride to a baking soda solution and watch the temperature rise! They will...

Investigators construct a makeshift balance and compare equal volumes of wax and water. They do the same for clay and water. Then they discover whether the wax and clay will float or sink in water. Ultimately this is a comparison of...

First graders understand that gases take up space even though you can't see or smell it. This is done through many experiments like trapping air in different sized bags, using balloons and plastic bottles, and blowing bubbles. They...

First graders gain knowledge about solids, liquids and gases by taking a look at the things around them. They have to classify certain picture cards based on which category they feel the picture falls under. As a whole, the class...

In this science instructional activity, students look for the words that are associated with the measurements taken in an average science class.

In this chemical bonding instructional activity, learners read about the invisible killer, dihydrogen monoxide. Students read about the products it is used in and the problems it causes to the environment. Then learners complete 19 short...

Students work in a mini lab where they measure the temperature every 30 seconds for several minutes as water is heated. They are asked what makes liquid different from a solid. Students view a PowerPoint on the model of liquids,...

First graders investigate the changing states of water.

Eighth graders explain what makes up matter.  In this atoms lesson students define an atom and what its components are and identify properties of elements. 

Tenth graders distinguish between chemical and physical properties and changes in matter when given specific examples. They view a video of sports activities. Students chose their favorite sport and design an experiment to improve sports...

Young scholars investigate the properties of air through hands-on activities in conjunction with the demonstrations in a 3-2-1 Contact Video.

Fourth graders identify characteristics of a simple physical and chemical change. They describe objects by the properties of the materials from which they are made and that these properties can be used separate. Students describe the...

Students examine the differences between elements, compounds and mixtures. Using diagrams, they compare and contrast atoms and molecules and describe various chemical reactions. They distinguish the differences between ionic and...

Students explore polymers by designing and preparing an inexpensive and effective reusable ice pack. They develop and test a design for a reusable ice pack in the science lab. Students apply chemical and physical properties of polymers...

Seventh graders describe and conduct an experiment that identifies the physical properties of light. They explore sources of visible light and an electromagnetic spectrum. Students explain the conversion of one form of energy to another.

Second graders explore states of matter when they change a liquid to a solid. Working students make ice cream in a zip-lock bag.

Ninth graders explore the relationship between heat and temperature. After performing experiments, 9th graders record their observations and discuss the results. They investigate the properties of heat and explore how energy possessed...

Students conduct an experiment. In this forms of water lesson, students observe ice to see what changes take place and then write in their journal about what they observed.

Eleventh graders use titration methods to study properties of antacids. They look at the strength, effectiveness, PH, and effect of supplements taken at the same time. They make observations after the different mixtures are combined and...
