Learners investigate the differences between a physical and chemical change. They observe various demonstrations involving physical or chemical changes, make predictions, and record what they see, hear, and smell.

Students design and conduct an experiment to investigate what happens when salt and ice come together and to determine if one form of salt is better for melting ice on steps and sidewalks.

Students observe a jar of pond water and predict how much life they think exists in the jar and watch a "Bill Nye: The Science Guy" video regarding protists. They participate in an online virtual pond dip where they begin to familiarize...

Students explore physical science by completing a lab assignment. In this sunlight lesson, students define a list of scientific vocabulary terms and complete fill in the blank questions. Students conduct a photographic experiment in...

High schoolers investigate the difference between plant and animal cells. They observe a variety o plant and animals cells by looking at a piece of cork, an onion, elodea, prepared slides of paramecium, human bone, frog blood, and human...

Students formulate a more accurate understanding of the true nature of scientific research and the challenges and rewards of field investigations.

Students brainstorm ants and their characteristics in a class discussion. They observe the ants and answer question pertaining to their behavior; then they apply the scientific method in creating and investigating a problem.

Students investigate growth rates of flowstone formations. They view a virtual field trip and discuss how flowstones form. They observe the cave fieldtrip and predict the growth rate for a cave formation. They graph growth rates and...

Students use a microcomputer connected to a light sensor and temperature probe to explore the reflection and absorption of radiation for different surfaces. Students follow instructions in this guided inquiry based lab and are then asked...

Learners investigate chromatography. In this chromatography lesson, students investigate a lab set up for chromatography.

Students practice calculating density and examine examples of the physical characteristics of soil. They solve a "crime" based on the evidence and laboratory investigations.

Learners investigate the physical and chemical properties of a candle before and after it is lit. They conduct a burning candle experiment, and complete a KWL chart and worksheet, recording the results of the investigation.

Students investigate ways that animals adapt to their environments through hands-on activities using isopods and an interactive video.

Pupils investigate how varying the concentrations, volumes, and other factors affects reaction rates. Students design and conduct investigations to obtain data used to create graphs of an uncatalyzed reaction vs. a catalyzed reaction....

Students investigate the mixing of light. They form a hypotheses to reason why color changes occur and they write conclusions and ask new questions arising from the investigation. Students identify the primary and complementary colors of...

In this science worksheet, students test the quality of water taken from a local source and test it in a lab for the ingredients present.

Seventh graders investigate the temperature change in open and closed containers. In this earth science lesson, 7th graders relate this lab activity to greenhouse effect. They create a line graph from data collected in the experiment.

Tenth graders investigate the process of how specific products are made from trees. For this chemistry lesson, groups of students must choose among ice cream, bubble gum, paper, toothpaste and lipstick. They research, design and...

Young scholars discuss the criteria for living things with their groups. They come to a consensus on at least five or more characteristics of a living thing. They determine if the lab samples are living, non-living, or other.

Third graders experiment with magnets. In this magnet experiment instructional activity, 3rd graders explore magnetic attraction and repulsion. Students rotate through four stations and investigate the properties of magnets.

Ninth graders perform a series of experiment to investigate heat transfer and phase changes. In this physical science lesson, 9th graders identify and calculate the different subatomic particles. They explain the importance of scientific...

Young scholars investigate the Polymerase Chain Reaction technique that is used to create larger amounts of a gene. They watch and discuss a PowerPoint presentation, explore a website, and write a report listing the materials needed to...

Young scholars explore how the energy flow through a system is related to trophic levels. They investigate how organisms affect the cycling of elements and water through the biosphere. Students participate in lab activities to observe...

Students design an investigation to test whether vegetation in an area helps regulate the ambient air temperature. They make comparisons between the investigation and global changes in climate. In groups, they present their findings to...
