Learners 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 test for the presence of enzymes in fruit and the specificity of those enzymes, as well as to identify and show the susceptibility of enzymes to certain environmental factors (temperature and pH) originating in the enzyme's...

Learners are introduced to basic engineering principles, road construction and material science. They explore how material properties and strength can be affected. Students become Civil Engineers by both creating Asphalt cookies and by...

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 conduct scientific investigation in which they observe glacial effects on landscape, develop and explain their own theories of how glaciers change land, and demonstrate understanding and explain basic motion and force principles.

Second graders examine different types of graphs and discover the meanings of the symbols used on them. After gathering data about themselves, their communities, and the world, they use that information to create graphs. Among the...

Students identify photosynthesis as a process through which organisms make their own food. They practice the process for writing the formula for the photosynthesis equation. Students describe how the processes of photosynthesis and...

In this density graph learning exercise, students graph data displayed in a chart. Students also calculate the density of each metal shown in the graph. Students answer questions about which detail is more dense.

In this density worksheet, students review this property of matter and the mathematical equations for density, mass, and volume. The worksheet has 10 fill in the blank statements and 3 word problems.

In this density worksheet, 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 worksheet has 1 graph, 2 short answer, and 5 word problems.

In this chemical reactions instructional activity, students by comparing the chemical reactions of baking soda and baking powder. This instructional activity has a graphic organizer and 7 short answer questions.

In this basics of science worksheet, students review the metric system, the difference between homogenous and heterogenous mixtures, the scientific method, and science lab first aid. This worksheet has 15 short answer, 43 fill in the...

High schoolers find the density of two substances. For this density lesson plan, students determine the density of water and ethyl alcohol and compare their densities. They enter their data into the computer to produce a class compiled...

In this thermodynamics learning exercise, students fill in the blanks with terms related to specific heat, calorimetry, phase changes, enthalpy, entropy and free energy.

In this experimental relationship worksheet, students read about direct and indirect relationships between variables in experiments. They answer three questions about relationships between variables.

In this chemical reaction worksheet, learners are given the details of an experiment where sodium chloride and silver nitrate are mixed in a chemical reaction. Students answer nine questions about the chemical reaction, they determine...

Third graders do dental flossing. In this dental care lesson plan, 3rd graders demonstrate proper dental flossing technique and describe the benefits of flossing.

Students investigate why cells divide. In this cell size lesson plan, students observe how far a solution travels into 3 different size model cells of agar. They answer questions about the most effect movement of "nutrients" into the...

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....

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

Fourth graders complete three activities. In this water supply instructional activity, 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...

Students understand how clouds are formed. In this cloud lesson, students participate in three experiments to make clouds. Students complete activity sheets for each experiment.

Learners 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...
