Students investigate air resistance using many objects. No formal lab procedure, just a few simple instructions leaves a guided-inquiry lab activity.
This activity can be conducted in the classroom. The students are given an opportunity to discover the basic concept of balance/counterbalance and how evenly distributed weight affects an object.
This activity is an inquiry where students will design an electrolytic cell that produces work in the form of lighting a bulb.
In this lab activity, students use brine shrimp as a proxy for krill to study how environmental factors impact behavioral responses of krill in the unique environment of Antarctica.
This learning experience is where students launch a bottle rocket and compare how long the bottle was in the air to how much water is placed in the rocket.
This lab activity allows students to apply their knowledge of Archimedes' Principle by calculating the maximum buoyant force that a ship can produce.
This activity is a lab where students design an experiment to construct a self-powered mini-submarine that stays underwater for at least 10 seconds, and then float back up to the top of the water level. Buoyancy and density are applied and discussed.
This classroom lab allows students to develop skills of the scientific method while exploring the characteristics of enzymes.
This activity is an inquiry based lab where students determine 3 ways to change the rate of the chemical reaction between hydrochloric acid and alka-seltzer.
This activity is a classroom investigation where students separate pigment in dyes in order to learn about mixtures and solutions. They use chromatography to design and experiment with a single variable to answer a question about which ink will separate the most - has the greatest variety of pigment.
This activity is a lab investigation where students design an experiment to extract pigments (AKA chromatography) from different colored, water soluble markers.
This activity is a lab investigation where students design an experiment to extract pigments (AKA chromatography) from different colored, water soluble markers.
This activity is a indoor lab where students investigate the current differences in different circuits where students build a small house and construct different types of circuits.
In this activity, students download historic temperature datasets and then graph and compare with different locations. As an extension, students can download and examine data sets for other sites to compare the variability of changes at different distinct locations, and it is at this stage where learning can be individualized and very meaningful.
This activity uses two interactive simulations to illustrate climate change, 1) at the micro/molecular level - modeling the impact of increasing concentrations of greenhouse gases in the atmosphere on surface temperature and 2) at the macro level - modeling changes in glacier thickness and flow as a result of rising surface temperature.
In this activity, students explore the role of combustion in the carbon cycle. They learn that carbon flows among reservoirs on Earth through processes such as respiration, photosynthesis, combustion, and decomposition, and that combustion of fossil fuels is causing an imbalance. This activity is one in a series of 9 activities.
In this chemistry lab experiment, students explore the properties of color using chromatography. Students will observe and compare color patterns to differentiate compositions of various colors. Students gather data on color patterns and develop new experimental questions based on their data.
This sequence of activities using real-world data to explain the importance of coral reefs and the relationship of coral reef health to the surrounding environment. Unit includes five activities.
This is an exploratory activity involving matter and density. There are many assessment pieces including a laboratory.
This activity is an interactive demonstration of the concept of density with a guided inquiry component.
