Students explain the causes of erosion, describe the effects of erosion, and devise a method of preventing erosion. They model the before-and-after-effects of erosion.

Students work together to design and build a paper rocket. They place a propellant in the contraption to make it fly. They discover Newton's third law of motion.

Students investigate human needs and how they have adapted to different environments. They complete an experiment to discover the effect of stress on muscles. They use the food pyramid to create a plan for healthy eating.

Students explain that photosynthesis is a process that plants use to convert light energy into glucose. They summarize photosynthesis as a chemical process in which the plant uses carbon dioxide and water to form glucose and oxygen.

Learners simulate photon transmission, scattering and absorption. In this physics lesson, students explain why some objects appear bright while others appear dark. They define photon and radiation in their own words.

Students identify the causes of hypothermia. In this biology lesson, students investigate the different types of heat transfer and heat loss. They discuss several practical measures to avoid hypothermia.

Students examine force and conduct activities that model parachutes and helicopters.  In this airplanes lesson students identify the forces that make airplanes fly higher and land. 

Amazing science can sometimes happen right before your eyes! The class gets cozy as they watch crystals grow. They use Epsom salts, rocks, and food coloring to create crystals. They'll observe the entire process, documenting every step...

Students explore birds, their territory, breeding, and seasonal movement. They research and collect information on birds through writing letters to ornithologists, reading in books, comparing web sites, and observing pictures. Students...

Students, through hands on games and activities, discover how bats live and how bats benefit ecosystems. They play a game designed to show them how echolocation works and another to show how mother bats locate their young through their...

Second graders create models, practice inquiry skills, work with fellow students in teams, and reinforce concepts discussed in class all by using the theme of BIOSPHERES.

In this unit conversion instructional activity, students are given 3 stories about situations where errors in the conversion of units caused dramatic problems in science. For each situation, students practice converting units to solve...

Students identify the desired features of an aircraft and the limits that they, the Wright Brothers, or NASA scientists might face in designing one, and methods to solve these. They review parts of an airplane and what makes it fly. They...

In this vertebrate activity, learners review the different adaptations for the 5 groups of vertebrates: birds, mammals, reptiles, amphibians, and fishes. This activity has 12 matching, 1 fill in the blank, and 7 short answer questions.

Learners build a model rocket. In this model rocket instructional activity, students explore a rocket launch cycle. Learners investigate the laws of physics for each part of the launch. Students build model rockets and launch at school.

Students examine effects of the sun on the planets in our solar system.

Students construct their own rocket-powered boat called an "aqua-thruster." These aqua-thrusters will be made from a film canister and will use carbon dioxide gas - produced from a chemical reaction between an antacid tablet and water -...

In this science worksheet, students create details given an imaginary story to reinforce the topics of mammals and birds. The second page has more puzzles for them to do.

In this Ares 1-X launch worksheet, students read about the path of this rocket's launch and solve 2 problems. Students find the number of seconds it took the rocket to fall from a given altitude and they determine how far from the launch...

In this rocket launch learning exercise, students solve 3 problems about the Ares 1X rocket and its launch, trajectory, and motion in both the vertical and horizontal direction.

For this astronomy and song lyrics worksheet, students are given 10 lyric fragments from different artists. Students select 3 of the fragments and write short essays about each to explain their thoughts from a human and astronomical...

Students describe the complementary relationships between pollinators and the plants they pollinate, identify adaptations that flowers have developed to "encourage" pollination, and create and draw their own "designer" flowers.

Young scholars complete a scavenger hunt worksheet as they find examples in their classroom, at home, etc., of minerals. Excellent worksheet!
