Elementary schoolers count and order objects using numbers 1-300. They bring recyclable items from home. Students group the items, skip count by 2's, 3's, and 5's, and arrange the items on a number line. Recyclable plastic bags are put...

How many planets can you name? Did you get all 13 in our solar system, including the dwarf planets, or were you surprised when you read there are 13 planets? The lesson helps scholars understand the scale of the universe including the...

How many pennies can an aluminum foil boat hold? That is the challenge in a collaborative activity designed to explore the concept of buoyancy. Learners use aluminum foil to build makeshift boats and test the weight they hold before...

Young scientists use electrolysis to separate water into its elements before experimenting with fire to learn about their properties. A helpful resource provides a reading passage and analysis questions. 

Not only do future engineers learn the difference between accuracy and precision, they also get some hands-on experience using different measuring tools. 

Watch your classroom turn into an arcade. Pupils work in groups to build pinball machines from boxes and other found objects. Gamers must incorporate a variety of obstacles and launchers into the machine to see their designs in motion.

First graders gain knowledge about solids, liquids and gases by taking a look at the things around them. They have to classify certain picture cards based on which category they feel the picture falls under. As a whole, the class...

Part of a larger online space science website, this page has a brief explanation of electromagnetic radiation and a chart of wavelengths as compared to common objects. There are four questions to answer about the information. This can be...

Students develop an understanding of the mole and molar masses of elements. In this mole lesson plan, students use beans to find their relative masses and draw parallels to the atomic masses of elements. Students work in teams and each...

Second graders examine the seeds in fresh fruit. For this seeds lesson, 2nd graders view different seeds and tell how they are alike and different. Students separate the seeds into groups according to their characteristics.

In this brightness of stars activity, high schoolers answer 7 questions about the apparent magnitudes of stars, the sun, and the moon. They compare the brightness of stars, galaxies, astronomical objects and the sun.

In this radioactive decay and half-life worksheet, students use given half-lifes to calculate the amount of time it will take for certain amounts of elements to decay. They also find the age of samples and determine how many grams of...

In this stellar magnitude scale worksheet, students use a scale showing the magnitude of objects in the sky to answer 5 questions about the brightness of the moon, the planets and stars.

Students complete a unit with cross-curricular activities to learn about a healthy body and maintaining their health. In this health lesson, students complete 8 lessons to learn about good health, a healthy diet, healthy foods, healthy...

Students experiment with varied balls to determine the bounce factor in centimeters. In this physics lesson, students experiment to find the height a ball must be dropped from the have the highest bounce rate. Students graph the results...

Fourth graders design and launch rockets.  In this rocket lesson, 4th graders observe the changes in outcome caused by size and fuel variables. Students navigate the NASA website to learn the parts of a rocket. Students load the...

In this calculations review worksheet, students convert from one metric unit to another, they identify significant figures in numbers, they find density of substances, and they solve problems using dimensional analysis.

In this physics review worksheet, students compare average and instantaneous speed, review Newton's laws, electricity, and magnets. This worksheet has 12 fill in the blank, 8 short answer questions, and 6 problems to solve.

Students perform a simulation in which they work for a toy company and have to figure out how many marbles of different sizes can be made with the provided material. They must design their own experiment to figure this out.

First graders investigate objects using rulers and magnifying glasses. They record their observations using a data-recording sheet and write a characteristic for each item they observe. They use the ruler to solve math problems.

Students examine tree rings to determine its age.  In this tree ring lesson, students examine core tree samples, identify the tree rings, and then determine its age. Students complete a worksheet, deciding which of the two core...

Students line themselves up from smallest to tallest at the chalkboard with the teacher marking their heights. After recording their names on the board next to their mark, they work with a partner to measure their height using several...

First graders explore measurement in relation to size of objects.

Students investigate work and power. For this energy lesson, students use the scientific method process to explore how much work and power it takes for a person to climb a stair case.
