Learners investigate the gas laws and how they apply to changes in gases. In this gas laws lesson, students use Boyle's Law and Charles' law to show the relationships between pressure and volume and volume and temperature of gases.

In this experimental design worksheet, students evaluate experiments using a design checklist. They suggest ways to improve the experiments and they identify all the components of the design.

Students watch video, The Elements, research information about elements using both the Internet and CD-ROM program, and create atoms out of gumdrops and licorice.

Students investigate the acidity and alkalinity of common household products in an experiment. They use red cabbage juice and litmus paper to show the difference between strong acids and bases as they work with vinegar, dish washing...

Students perform two experiments to show the properties of enzymes. They use pectinase to produce apple juice from applesauce to show enzyme action and then taste the difference between raw and boiled papaya seeds as evidence of enzyme...

Students extract DNA from green peas. In this DNA extraction lesson plan, students use a blender to chop up peas, they mix them with a little soap, they tenderize them and they mix them with alcohol to see the DNA precipitate through the...

Students investigate diffusion using different solutions of chemicals placed in agar dishes. In this diffusion lesson plan, students observe 3 demonstrations of diffusion using perfume, food coloring in water and sugar cubes in water....

Fourth graders complete three activities. In this water supply lesson, 4th graders learn that water can exist in different forms and watch a demonstration of each form. Students explore the water cycle and make a water cycle using the...

Students explore objects before and after heating using their senses.  In this matter and energy lesson, students experiment with a variety of objects and use their senses (except taste) to make predictions and record observations...

Students observe that plants need air, food, light, and water to survive.  In this plant biology activity, students observe the growth and development of two plants, one is the control plant and the other is denied either air,...

Eighth graders explain the difference between acids, bases and neutral solutions. In this chemistry lesson, 8th graders describe the properties of each. They determine the pH of an unknown solution using the indicator paper and pH scale.

In this density activity, students use the mass of aluminum and copper at different volumes to create a graph in order to calculate the density of these metals. This activity has 1 graph, 2 short answer, and 5 word problems.

Young scholars research the growth of coral. In this coral polyps instructional activity, students simulate the growth of coral by using available materials to grow crystals. Young scholars record observations in a scientific journal.

Sixth graders use teacher prepared samples of substances. They perform the same observations and complete charts for each substance. After recording and analyzing their results, 6th graders make changes in the recipes to create a better...

Students use water, beakers, hot plates, paper dots, and goggles to participate in a hands on activity where they see how a convection current creates wind. For this convection current lesson plan, students participate in a hands on...

Develop an understanding of the universe. Learners answer 10 multiple choice questions about several topics in astronomy. Questions contain information about the age of the universe, gravitational attraction, galaxies, planets and comets...

There's no need to water down the resource. A tutorial takes learners through the process of creating dilutions for any solution. Specifically, it focuses on serial dilutions with successive factors of 10.

How are chemical reactions affected by gravity? Learners explore the phenomenon of effervescence as part of the Christa's Lost Lessons series. They compare findings in an experiment on effervescence to a video of a similar experiment in...

Don't be shocked when your class has a blast making their own batteries! Science scholars examine a dry cell battery, then design and construct a wet cell battery. The activity guides them through the parts of a battery, the variables...

After reading an informational text detailing the ins and outs of snowflakes, scholars draw their own special design then work cooperatively to role play a snowman building scenario. 

Third graders complete an experiment to introduce them to the concept of water pressure. In this water pressure lesson plan, 3rd graders create pressure in a water bottle and observe the force of water that is created.

Give young scientists a new appreciation of fresh, clean drinking water. After learning about the ways astronauts recycle their air and water, your class will work in small groups creating and testing their very own water...

For this identifying the weather terms activity, students read phrases about the weather and choose the term being described. Students choose 11 multiple choice answers.
