In this activity, learners use a microscope to examine three different microbes: bacteria, yeast and paramecia. Educator will need to prepare the yeast solution one day before the activity.

This activity (on page 3 of the PDF under GPS: Body Electricity Activity) is a full inquiry investigation into conductivity.

In this activity, learners use their senses to collect information about a fruit and record their findings in a Science Journal.

This three-part lab helps learners understand the essential principles governing diffusion and osmosis.

In this data analysis activity, learners quantify the abundance and distribution of sea scallops in and adjacent to the Mid-Atlantic closed areas.

In this activity, learners explore the different salinities of various sources of water by taste-testing.

In this activity, learners use two different techniques to estimate how many little things fit into one bigger thing.

In this activity, learners create an electrical circuit and investigate how some dissolved substances conduct electricity.

In this set of outdoor games, learners increase their awareness of the outdoor environment by going on a scavenger hunt and an out-of-place hunt.

In this math lesson, learners apply the concepts of ratio and proportion to the capture-recapture statistical procedure.

In this laboratory activity, learners design an experiment to evaluate how environmental factors influence the growth of molds.

In this activity on page 7 of the PDF, learners investigate the solubility of gas in water at different temperatures. This experiment will help learners determine if temperature affects solubility.

In this data analysis activity, learners use data collected by the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) to study Chilean sea bass populations.

In this genetics activity, learners create imaginary creatures known as "Reebops" to explore the relationships between genes and inherited traits.

In this activity about engineering, nutrition, and physical activity, learners design and build a healthy bone model of a space explorer which is strong enough to withstand increasing amounts of weigh

In this activity, learners will investigate the impacts of harmful phytoplankton using NOAA's Coastal Services Center Harmful Algal Bloom Forecasting (HABF) Project data.

In this activity, learners compare the ways of life of Plains Native Americans who hunted and moved frequently to follow the buffalo herds, and Native Americans who farmed and lived in more permanent

In this activity, learners observe how salinity affects the freezing point of water by making and enjoying ice cream.

In this activity, learners collect, categorize, weigh and analyze classroom trash and discuss ways that engineers have helped to reduce solid waste.

In this activity, learners solidify their conceptualization of cells by building a model of a cell in a ziplock bag.
