Delv into the states of Matter. Students engage in the scientific inquiry process to uncover the exciting world of Matter. They watch a series of videos, and conduct experiments in order to collect and analyze data on the various state...

Here is part one of a two-part lesson in which scholars investigate the changing states of water—liquid, solid, and gas. With grand conversation and up to three demonstrations, learners make predictions about what they think will happen...

Here is part two of a two-part instructional activity in which scholars investigate the changing states of water—liquid, solid, and gas—and how energy from heat changes its molecules. With grand conversation, two demonstrations, and...

Super scientists visit ten stations to predict, observe, and draw conclusions about the physical and chemical changes that occur when different states of matter—liquid, solid, and gas—are placed under a variety of conditions. To...

Crystals are more than meets the eye! Can learners tell them apart simply by observation? As they examine five samples with a magnifier, they find that appearance alone is not enough. This serves as an introduction to a mini unit on...

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...

Liquids, gases, and solids are the states of matter in which scholars investigate in a lesson plan that offers in-depth information and engaging activities that look into the three states and the changes their properties make when mixed...

Once investigators have learned how their mystery liquids interact with water during the preceding activity, they now use their observations to identify them. This is an ideal conclusion to the mini unit on the properties of water. 

Blue-tinted water is added to unknown liquids that have been tinted yellow to find out how they interact. This is a memorable activity that is part of an investigation on the properties of liquids, which is part of a unit on the...

Take a "conservative" approach to planning your next unit on mass and matter! What better way to answer "But where did the gas go?" than with a lab designed to promote good report writing, research skills, and detailed observation....

From gas to liquid condensation to solid frost, water undergoes phase changes before learners' eyes! Using ice, salt, water, and a metal can, they set up an investigation that can be used in a physical science setting, or as part of a...

This is one in several lessons that explore the relationship between temperature and phase changes of water. After some discussion, elementary physical scientists place wet paper toweling on a hot and a room-temperature water bag...

If the area you live in is arid, or the preceding experiment in this unit didn't yield obvious results, use this one in place of it to help reveal where condensation comes from. The mini unit that this is part of a comprehensive...

There's a container for every matter—liquid, solid, and gas. Pupils design three different containers, each with the capability to hold one of the states of matter, and share their design with the class.     

Never trust an atom; they make up everything! Young chemists make modeling dough and add another ingredient to change the properties. Scholars then compare the properties of emulsion to composite materials. A reading passage and analysis...

Ah, caffeine! What would some of us do without it? Teach your high school chemistry class the concept of sublimation as they complete a hands-on experiment to visualize the changes caffeine undergoes during heating and cooling....

Putty is proof that learning can be fun! Share the wonderful world of polymers with your class through an experiment. Young scientists create their own silly putty, then examine its properties.

A phenomenal activity on sound is here for your third graders! In it, learners engage in hands-on activities, watch video, take part in Internet activities, and complete tasks in cooperative groups in order to explore the world of sound...

A fantastic lesson plan on survival in outer space should excite your learners! Pupils explore the challenges that living, working, and surviving in space elicit. They focus on the spacesuit itself; how it protects astronauts, and...

Take young geologists on an exploration of the rock cycle with this six-lesson earth science unit on rocks and minerals. Through a series of discussions, demonstrations, and hands-on investigations your class will learn...

Who can grow the best crystals? Challenge class members to develop strategies for enhancing growth in the crystals. Through a lab investigation, learners study the properties of crystals and test the effectiveness of different...

Chemical and physical properties give compounds an identity. Learners use the identity of a compound to predict what it is. By performing different tests like solubility, flame, heat, and reactions, individuals attempt to identify an...

After challenging themselves to correctly choose the form of erosion and length of time required for a given landform to develop, earth science class members model mechanical and chemical weathering with various lab demonstrations over...

Solidify understanding of the properties of crystals by crushing them to compare hardness. After some class discussion, a procedure is planned, and then small groups go about making observations as they crush five different crystal...
