Students formulate a testable research question containing a comparison and a quantitative measure. They state the null and alternative hypothesis for a testable research question. In addition, they describe some of the abiotic and...

Learners identify units of measurement. In this measurement lesson, students predict the length and width of their hands and feet. Learners discuss their findings and if their predictions were correct.

Learners investigate safe laboratory procedures, classroom management guidelines, and group roles and procedures. They study a set of safety guidelines with their parents, and to sign a contract stating that they understand the...

Students collect and analyze data on a fictional cereal company's products. In this measurement lesson, students collect data from cereal boxes (weight, volume, surface area, etc.) to determine if the boxes labels correctly inform...

Crystals form before your very eyes! What sixth grader wouldn't enjoy this lesson on igneous rock formation? Using hot Salol, junior geologists observe the crystal formation process as the material cools. This comprehensive lesson plan...

Chemistry explorers prepare a crystalline derivative and find its melting point. Once they discover the melting point, they can identify whether the substance is pure or an aldehyde or ketone. This outstanding laboratory activity helps...

We see curved mirrors every day in spoons, rear-view mirrors, stores as a safety measure, make-up mirrors, and in novelty stores. Scholars explore the changes to an image based on the curve of the mirror, the location of the image, and...

Step-by-step procedures are outlined in the learning exercise and calculations for junior chemists to perform in their science journals. This laboratory exercise is intended for experienced chemistry learners.

Scientific method, linear measurements, friction, inertia. Imagine learning scientific vocabulary in an ELA class. Before researching and developing a presentation about simple machines, class members build a common, but decidedly...

Learners explore how to measure length and volume. They compare and order objects according to their measurable attributes and measure items using non-standard units. Students put 4 pencils in order from shortest to longest after...

Students explore the concepts of mean, median, and mode. They develop an understanding and familiarity with these concepts. Students explore mean and median in an efficient way. Students explore three different measures of center.

Compose and decompose sets of 13 and 14 and compare sets of each with your little learners. They use objects to construct sets of 13 and 14, record their answers, and compare sets in several different ways.

Students take measurements throughout the day using a simple sundial called a gnomon. They record the results on a Data Log and convert from English units to metric (S.I.) units. Data points are plotted on the same graph and analyzed.

Ever wondered how many pieces of paper a binder clip can hold? Viewers of a short video are about to find out! Given measurement data for three different sized binder clips, learners must develop a method for figuring out how many pieces...

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...

Young scientists grab their measuring tapes, rulers, and yard sticks as they see how big Arctic animals really are. To conceptualize the trait of height or length, each small group will measure out the entire length of an arctic animal....

Potty humor is always a big hit with the school-age crowd, and potty algebra takes this topic to a whole new level. Here the class develops a model that connects the dimensions (radii, paper thickness, and length of paper) of a...

Students calculate the standard and metric measurements of a playground. In this measurement lesson, students use GPS coordinates and graphing calculators to determine the dimensions of an area outside of the school in both standard 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,...

What starts as a basic question of division and remainders quickly turns abstract in this question of related ratios and radii. The class works to surround a central coin with coins of the same and different values, then develops a...

How do we determine how much information to include and what can be left out? By playing a game of 20 questions, the class generates the best strategies for finding a number. They then move on to guessing the next letter in a short...

Cooperative groups select from one of four scenarios regarding hurricanes, greenhouse gases, thunderstorms, or the global climate domino effect. They discuss what kind of research needs to be conducted to address their chosen scenario...

Young geometers become pool sharks in this analysis of the angles and lengths of a trick shot. By using angles of incidence and reflection to develop similar triangles, learners plan the exact placement of balls to make the shot....

Students discuss what heat is and how it travels. They discover that one way to cool an object in the presence of a heat source is to increase the distance from it or change the angle at which it is faced.
