Weight, time, length, cost, and mass are all things we can measure. Learners are introduced to the concepts they'll need to know before embarking on any measurement adventure. They are introduced to each type of measurement and types of...

Teach the masses about the metric system with this hands-on measurement lesson. Given a fruit or vegetable, learners estimate, measure, and convert its mass using the metric units gram and kilogram.

How do you teach a student with visual impairments about the conservation of mass? You use tactile models that represent the theoretical concept. Baking soda and vinegar are used to add gas to a deflated balloon. Learners will feel the...

Conversion immersion — it's measuring mania! A set of four activities teaches scholars to convert between customary and metric units. Resource covers unit conversions in length, temperature, weight/mass, and volume.

Atoms, elements, and molecules, oh my! Teaching the fundamentals of chemistry to curious sixth graders has never been easier to accomplish. Here is a resource that pulls together everything needed to get them off to a good start,...

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

Prove the Law of Conservation of Mass through a lab investigation. A well-designed instructional activity asks groups to combine materials and monitor indicators for chemical reactions. Measuring the mass of the reactants and products...

Investigate the Law of Conservation of Mass through a lab exploration. Individuals combine materials to initiate chemical reactions. They monitor for signs of reactions and measure the masses before and after the reactions for...

Will the block float? Pupils take measurements to calculate the volume of various blocks of different materials. Using a scale, they determine the mass of each block and then calculate their densities. Scholars finish by ranking the...

Explore the connection of surface area to bonding within atoms. Learners complete lab investigations to model changing surface area with different sizes and concentrations of atoms. A flour fireball demonstration follows the labs to...

Young scientists learn that seeing isn't necessarily believing when it comes to the states of matter. After performing a fun class demonstration that models the difference between solids, liquids, and gases, children complete a series of...

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,...

Swimmers know to float by turning their bodies horizontally rather than vertically, but why does that make a difference? In an interesting lesson, scholars explore buoyancy and the properties of air and water. They test cups to see which...

If a car gets heavier, it goes farther? By running an activity several times, teams experience Newton's Second Law of Motion. The teams vary the amount of weight they catapult off a wooden block car and record the distance the...

Stop and drop what is in your hand! Pupils investigate how form effects drag in the 12th part of a 22-part unit on aviation. Groups create equally weighted objects and determine which one falls the fastest by collecting data.

Bathymetry is not a measure of the depths of bathtubs! Through the three lessons, scholars explore two different types of maps and how they are made. The resource focuses on topographic and bathymetric maps and teaching the techniques...

Adjust the melting time of ice without varying the temperature! Learners experiment with different materials to decide how the materials affect the rate an ice cube melts. They then connect their findings to the conductivity of each...

The first STEM lesson in a group of 10 explores composting. After discussing how to make a better tomorrow, classes are challenged to track garbage in their communities, visit a local waste management facility, and conduct a survey...

Hydrologists create a concept map about how water is used and a sentence strip defining water and describing its unique properties. Small groups work together to fill a small milk carton and compute the mass of water inside. The next...

Preparing for an AP test is about more than bubble sheets and memorization. The two activities in this resource require a direct application of skills learned throughout an AP Physics course.
