Learners describe the characteristics of algae. In this biology instructional activity, students perform a series of experiment to explore algae. They investigate the basic things algae need to survive.

Students explore the theory of simple harmonic motion (SHM) by performing hands-on, practical application experiments. In this harmonic motion activity, students use strings of various lengths and bobs of different weights to create a...

Students develop procedures to explore the behavior of fish.  In this scientific experiment lesson students from a hypothesis, write a question, identify different variables and controls in their experiment. 

Third graders study and define force. They determine that the cause of movement is pushing or pulling which are the types of force used when operating simple machines. They experiment to determine which object requires the most amount of...

Students discover what simple machines are and identify a gear, a pulley, and a lever. In teams, they build at least two models each of simple machines and challenge them with specific instruction cards. Finally, students present and...

Sixth graders plan and conduct an experiment on food spoilage. They design the experiment, create a display, record and analyze data, and make inferences regarding the results of the experiment.

Fourth graders choose a simple machine and write about they way they believe it will work. Students experiment, write down procedures used and record observations. They will find a picture of the machine and add it to their report.

Students observe examples of gravity, friction, and force on the playground. They then experiment and participate in a variety of activities in centers back in the classroom.

Students construct an extremely simple series circuit that powers a lamp on and off with a switch. They are in groups of 4 and are given a set of components and have to build the circuit working together as a group. Finally, they have to...

Students investigate seed germination. For this lesson on scientific prediction, students conduct a scientific experiment using oat seeds.

Students demonstrate an awareness of the types of simple machines and classify common objects in relation to the simple machines involved.

Fourth graders participate in a scientific experiment involving growing lima beans. Students plot information gathered on included charts and graphs. Students use the steps of the scientific method throughout this experiment.

A combination of informative text, photos, and graphics comprise this sharp show on electromagnetic radiation. Some slides mention hands-on activities for demonstrating concepts, so if you want to include them you will need to figure out...

In this switched circuit experiment learning exercise, students follow the procedures to build a simple circuit with batteries, light bulbs and paper clips.

In this pulleys experiment worksheet, students follow the procedures to set up an experiment with one and two pulleys, a rope, bucket and load.

Students, by way of the Olympic Games event of ice skating, are introduced to the concepts of gravity. They try some hands-on gravity experiments and explore the concept of gravity through art.

In this conductors and insulators experiment worksheet, students follow the procedures to set up an experiment that tests which common materials are conductors or insulators.

Students investigate temperature and pressure with simple laboratory equipment. They use a handheld with sensors and probes to study temperature and pressure. Students explore the nature of gases with respect to temperature and are able...

students investigate light levels under the ocean by conducting several simulations. After creating solutions representing seawater, they shine a light sensor on it to discover how light diffuses and is absorbed by the impurities in the...

Students will visualize how DNA is extracted from cells by performing a simple laboratory experiment. They will then use this knowledge to further understand how scientists are using DNA extraction to try to clone human cells, and to...

Students research and conduct experiments with several types of simple machines. They examine levers, pulleys, inclined planes, wheels, axles, wedges and screws and then consider the physics behind "Green Eggs and Ham".

Students participate in a culminating activity for a unit on Energy and Simple Machines. They are challenged to incorporate simple machines in to a complex mechanical system. While designing and testing their machine they will also...

Fourth graders provide a habitat for live mealworms and observe their life cycle. In this animal life cycle and scientific inquiry lesson, 4th graders create a habitat for a live mealworm and observe and record related data as it grows....

Sixth graders discuss nutrients and examine foods for starch.  For this starch testing lesson, 6th graders use iodine to test foods for starch and record their results. Students complete a worksheet and self reflection.
