Students describe how inclined plane and pulleys make work easier. In this physics instructional activity, students calculate work done and mechanical advantage of both simple machines. They collect data from the experiment and construct...

Young scholars experiment with common objects such as spools, string and soap to determine how pulleys make it easier to move large objects. They look at the difference between fixed and movable pulleys. They examine the many uses...

Fifth graders use information from their text to read and discuss pulleys and levers. They examine a top sketch of the arrangement of a fixed pulley. Working in groups, 5th graders perform experiments to test the effect of using a pulley...

Students investigate to use simple machines for the purpose of maximizing the work provided by mechanical advantage. They design an experiment that illustrates how to move a load easier and then calculate the amount of work performed...

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...

Sixth-grade scientists gain understanding of how genetic traits manifest with simple experiments, such as determining whether their tongues are roller or non-roller, taster or non-taster. Extensions include performing tests at home with...

A teacher's guide for Kindred provides instructors with a wealth of materials to enrich either a full-class reading or independent study of Octavia E. Butler's popular science fiction novel. The activities are designed to...

Celebrate the whimsical world of Dr. Seuss on Read Across America Day with a collection of science, technology, engineering, the arts, and mathematics activities, each linked to a popular Dr. Seuss story. 

Do predators look for different things in different seasons? The quick interactive shows how some species survive longer in one season than another based on the conditions. The challenge questions encourage pupils to demonstrate that...

When you need a review worksheet for your AP biologists on water and nutrient transport in plants, this one is for you! From the simple stuctures involved to the complex mechanisms that make it happen, the details of transport are...

While a simple exploration of plants, this resource which is designed for first graders, provides a series of extension activities to make for a rich experience. First, learners watch a video about plants and label the parts. Then, they...

Humans are so used to gravity as a force that we don't tend to pay much attention to it on a daily basis. Through a couple simple activities, learners experience changes to their center of gravity and come to the understanding that...

There's an app for that! Pupils learn to build an app that will store data on an Android. The lesson introduces class members to the tiny database, TinyDB, for Android devices. A video tutorial provides an example that uses the...

You don't want to break these chains! Show young chemists and biologists the basics of polymerization with a simple interactive. The resource gives learners three types of polymers to experiment with, as well as a brief tutorial about...

Sugar isn't good for you, but it's great for microbes. A simple experiment has pupils investigate the digestion of starch by microbes to produce sugars. They apply two bacterial cultures, an amylase solution, and distilled water on a...

Young scholars experiment and discuss circuits and how they work. In this science lesson plan, students construct a telegraph machine using cardboard, wires, battery, electric tape and masking tape. They investigate what happens as the...

Learners research human health by reading an educational story in class. For this oral health lesson, students identify the importance of brushing their teeth and consuming calcium. Learners read the book A Teeth Changing Experience...

Students identify the components of sound. They describe the relationship between pitch and frequency and explain the terms sympathetic vibrations and resonance. They perform simple experiments about the world of sound and explain the...

Fifth graders understand what a lever is, how it works and what the parts of a lever are. In this first class lever lesson plan, 5th graders label pictures and design a lab lever. Students predict the outcome of experiments with their...

An evaporation investigation! This collection of slides walks future scientists through the process of setting up an experiment on how to speed up evaporation. The experiment is simple enough to use at the beginning of the school...

Opening with one slide on cnidarian reproduction, this PowerPoint is more focused on phylum platyhelminthes. It touches on flatworm structure, feeding, body systems, and reproduction. Simple, yet informative, this resource will support...

Here is a fun little exploration of the potential energy potential of falling water. Learners drop water from various heights using a straw, and they analyze the diameter of the splash. Pair this with two more activities of the same...

Your class will agree that this is the best way to demonstrate the greenhouse effect: making solar s'mores! Using a clear plastic cups as mini atmospheres, lab groups compare how adding different materials affects the melting rate of...
