Quiz your learners on density, mass, and volume with six equations. Each equation prompts kids to consider an object made of a different material, and to find the desired measurement.

Weathering is not necessarily a result of the weather. Scholars conduct an experiment to explore the effect of surface area and volume on the weathering process. They create their own sugar cube rocks using the same number of cubes—but...

Estimate the value of one of the most famous irrational numbers. The hands-on instructional activity instructs classmates to measure the circumference and diameters of circles using yarn. The ratio of these quantities defines pi.

After reading "Aquatic Alchemy," an article about recapturing water for reuse when in space, your class will use calcium hydroxide or hydrated lime to purify cloudy water. Geared toward high school chemistry or environmental science...

Get things moving with this elementary science unit on simple machines. Through a series of nine lessons including teacher demonstrations, hands-on activities, and science experiments, young scientists learn about forces, motion,...

See how design and geometry go hand in hand. The activity asks learners to use geometry to design a backyard garden given dimensions of each feature. Scholars work with ratios and scale to develop an accurate scale drawing that includes...

Temperature rises and land disappears! Through a lab exploration, learners understand the effect of temperature increase on water similar to the effect of global warming on our oceans. As they heat the water in a flask, they measure the...

Circles, circles, everywhere! Pupils learn all about circles, central angles, inscribed angles, circle theorems, arc length, area of sectors, and radian measure using a set of 12 lessons. They then discover volume formulas through...

What makes particles attract? Here, learners engage in multiple activities that fully describe colligative properties and allow the ability to critically assess the importance of these properties in daily life. Young chemists...

The Law of Conservation of Matter can be complex for young scientists to fully grasp. Use this experiment to help simplify the process as pupils perform two experiments to determine mass: one that melts a substance and the other that...

The Deepwater Horizon oil spill directly impacted an area of the Gulf of Mexico the size of Oklahoma. A marine biology activity looks at the impact of an oil spill on the deeper parts of the ocean. Scholars download actual data collected...

How do you create a map of the ocean floor without getting wet? Middle school oceanographers discover the process of bathymetric mapping in the third installment in a five-part series of lessons designed for seventh and eighth graders....

Get your class outside to observe their surroundings with a lesson highlighting weather patterns and seasonal changes. First, learners take a weather walk to survey how the weather affects animals, people, plants, and trees during...

How does radiation affect our daily lives? Answer that question and others with a lesson that discusses radiation and its use in thermal energy transfer through electromagnetic waves. Pupils investigate vaporization and...

Learn about polymers while playing with shrinky dinks. Young scholars create a shrinky dink design, bake it, and then record the area, volume, and thickness over time. They model the data using a graph and highlight the key features of...

Middle schoolers redesign their school to make it more energy efficient, and create a model of their design. Learners get together in groups of 5, and they take on the task of making their school more energy efficient. To do this, they...

This lesson starts with geometers discussing how to find the volume of a cone and pyramid, using what they know about the volume of a cylinder or prism. Then, using the formulas, they calculate the volume of cones and...

Plant respiration can be a difficult concept for young biologists to grasp; with a hands-on lab, learners can collect and graph data, then calculate the metabolism rate for the plants they studied. If you do not have a respirometer,...

How do you properly illustrate the extreme size difference between two planets—Earth and Jupiter? With the help of jellybeans, of course! Create a scale model of Jupiter's mass compared to Earth using a fishbowl, 1,400 beans, and a...

Are you getting enough vitamin C? Young scientists determine the amount of vitamin C in fruit juice samples. They accomplish this task by adding DCPIP solution to the samples until the blue color of the DCPIP persists. Once this happens,...

Forget your ID number? Your pupils learn to use logarithms to determine the number of digits or characters necessary to create individual ID numbers for all members of a group. 

We can't see most gases and we can't see things at the molecular level — but that's about to change! A simulation shows pupils the activity of molecules in a gas. The simulation allows scholars to vary the volume, heat, and...

Explore the chemical components of water through an electrolysis reaction. Scholars use a battery to divide various water solutions into different gases. As they collect the gases, they measure the volume and make a comparison to the...

Enjoy a hands-on lesson that will certainly hold water with your classes. Young scientists design an experiment to determine the materials that absorb water the best. They test both man-made and nature-made materials and conduct...
