Tenth graders identify the parts and functions of the cell. In this series of science lessons, 10th graders investigate crystal formation in covalent compounds. They investigate the factors affecting reaction rates.

Students identify animals that are active at night and the reasons why. They examine the features needed to be a nocturnal animal. They create a representation of one of the animals.

Students use Excel to explore population dynamics using the Logistic equation for (S-shaped) population growth. This activity is primarily intended as an introductory tutorial on using Excel.

Students examine the energy dependence of active transport as well as te properties of specificity, competition, saturation, and inhibition. They anesthetize an insect and inject saline into the abdomen.

Raise the energy level of your physical science class with this exciting hands-on activity. Applying their knowledge of kinetic and potential energy and Newton's laws of motion, young engineers use foam tubing and marbles to create...

Here is a physical science activity where pupils place thermometers inside of a white and a black paper pocket and place them under a lamp. They record and compare the temperature increase over a ten-minute period. Have your class...

Young scientists present their experimental designs from the previous experiment. The ninth instructional activity in the series outlines what learners should present, what class discussions should happen, and the solution NASA came up...

Groups make a model of an Ocean Commotion exhibit based on what they saw during the fieldtrip. These dioramas can be used as an informal assessment of student knowledge acquired at Ocean Commotion.

Investigate bubbles through the use of scientific inquiry. Pupils blow bubbles using several methods and measure the resulting bubble print. Measurements are recorded on a data table and transferred to a bar graph. Results are discussed...

A good concept map requires high thought processes. This makes it a great tool for teaching and evaluating your pupils. A helpful article describes a great approach for teaching young scholars the art of concept map building and how best...

Using footballs, basketballs, tennis balls, and more, learners conduct experiments to illustrate Newton's Laws of Motion.  The experiments are conducted outside, and require them to throw, kick, and hit a variety of balls. Your...

This optional lesson introduces the class to the idea of a minimum spanning tree. The activity focuses on determining an algorithm that will find the most efficient path in a network to transfer data. 

How do people determine if something is acidic or basic? Learners make their own acid-base indicators using red cabbage and then determine the acidity and alkalinity of different substances. First, they test substances of known pH and...

Help young scientists connect with nature and learn about trees with a fun life science activity. Heading out into the school yard, children choose a tree to adopt, taking measurements, writing descriptions, and drawing sketches of it in...

Celebrate the circle of life with this fun hands-on activity. After cutting out, gluing together, and assembling this visual model, students are able to spin through and observe the life cycle of penguins.

Students sort teddy bears according to types and then graph the results. They each bring a bear to class and then discuss their similarities and differences. Once the bears have been sorted into groups according to size and color,...

Students identify the food groups and agricultural sources of pizza ingredients. They construct a construction paper pizza, identify the crops grown for pizza ingredients, and make and eat English muffin pizzas.

Students, working in groups, create "artificial seeds" for a wind dispersal experiment. After trial runs, they redesign their seeds, and re-test them under the same conditions. Finally, they interpret, compare, and evaluate the original...

Students are introduced to biodiversiy. They use a simulation of two forests, one planted with only Douglas Fir trees, and one with diverse species of trees. Students also use the simulation of two forests, one a monoculture of only one...

Discover the coldest animals in the world with a lesson about the Arctic habitat. Kids use a glossary and information sheet about animals found in the Arctic Circle to complete several activities, including tracking the lemming...

Students in this inquiry-based experiment, put in the role of a method development chemist. The scenario they are given is that a train wreck has occurred resulting in a chemical spill. Students are told that the spill mixture consists...

After a whole-class discussion of water reservoirs, ten liters of water are given to each lab group to represent Earth's total amount of water. They divide the water into smaller containers, each representing one of those reservoirs. The...

Curious physical scientists follow a lesson on the properties of water with this lesson on distillation. They observe a miniature water cycle model that filters dirty water into clean water. These two lessons combined are an enriching...

Learners explain the complexities of environmental decisions, rather than to recreate the actual circumstances and outcome of the original case. They simulate a real environmental case a regarding the Pine Barrens of Long Island, NY.
