Second of six lessons in a unit on dissolving, this one focuses on how sugar behaves in different liquids. Learners stir it into water, alcohol, and oil and make observations. This lesson can stand alone, but is best used as part of the...

Here is the first of four experiments to differentiate among unknown liquids by their behaviors and properties. Pupils observe how different liquids respond to being placed on plastic and paper, and they take notes about their...

Fourth in a set of several little lessons on density, this one compares the density of fresh and salt water. First by demonstration, and then by a hands-on activity, learners find that adding salt increases the density, as is evidenced...

Couches, carpets, and even computer keyboards now advertise they are spill-resistant, but what does that mean? Scholars use physical and chemical methods to coat surfaces with thin films to test their hydrophobic properties. Then they...

Rotating through five stations, evolutionary biologists explore the question of how changes in DNA facilitate the changes in a population over time. High-quality, colorful cards of animals, skeletons, skulls, and DNA sequences can all be...

If you have taught the first instructional activity in this mini unit, learners already know that cabbage juice and vinegar cause chemical changes in some materials. Now, they get a chance to use them to compare the liquids' reactions to...

How can you tell what an owl has eaten? Study the food chain and flow of energy in an ecosystem by dissecting an owl pellet and noting the bones found inside. Additionally, the instructional activity includes a game about consumers and...

How do plants and animals get their food? Learn about where energy comes from, how animals store energy, and aerobic respiration, in a instructional activity that allows scholars to diagram energy flows. 

Third graders observe and create a record of seed growth over time. After planting a seed, 3rd graders record their observations of the seed's growth over a three week period. Upon conclusion of the experiment, they write a paragraph...

Students engage in a variety of activities designed to facilitate the understanding of DNA. Activities include preparing human chromosome spreads, separating a mixture of dyes using gel electrophoresis and extracting DNA from onion cells,

Students extract DNA and test for its presence from unroasted (raw) wheat germ using a prescribed procedure. They modify the procedure to provide a less expensive, easier method. They also extract DNA from different available plant,...

Students identify the different parts and functions of the cardiovascular system. In this forensics lesson, students collect and analyze evidence on a fictional crime. They describe different causes of cardiac arrest.

In this polymer worksheet, learners make two types of cross linked polymers and they test their physical properties. These include their response to agitation, stretchability, viscosity, and resilience.

Students perform an experiment to demonstrate the principles of antibody-antigen binding, the secondary immune response, cross reactivity, and complement fixation. The materials to be used include antibodies from a rabbit that was...

Fourth graders explore the history of electricity. In this electricity lesson, 4th graders review the connection between electricity and magnetism. They do a research project on the history of electricity. 

Middle schoolers explore a specific method of identifying fungi, using a written key and an illustrated key. Powdery mildew fungi can be identified to genus by the morphology (appearance) of the sexual stage (cleistothecia).

Students explore the senses. In this Applied Science lesson, students investigate the items in "feely" boxes with their hands, both touching the items and shaking the boxes to hear the sound the items make. Students also smell and taste...

Second graders explore simple machines. In this technology lesson, 2nd graders look at pulleys and gears and what the uses are for each. They complete a worksheet comparing the two. 

Third graders discuss electric currents. For this circuit lesson, 3rd graders create a picture of a battery circuit and a light bulb. They show the positive and negative charge and the flow of electrons. 

Third graders discuss how energy is created. In this energy lesson, 3rd graders look at how a city receives energy and how it is made. They create their own generator using a pin wheel and pipe cleaners. 

Fifth graders look at the impact of sound and noise. In this sound lesson, 5th graders review the decibel and common sounds along with their noise levels. They complete a worksheet about the different sounds that one might hear during...

Recording scientific evidence allows for important discoveries and conclusions. A remote learning resource outlines how to create a field journal to record scientific observations. The outline resource includes notation about the...

Get your class to take a closer look at DNA. Pupils conduct research to determine the methods used by scientists to analyze the molecular structure of DNA. The class members investigate different types of molecular imaging along with gel...
