Learn more about the longest day of the year in the northern hemisphere through these multidisciplinary hands-on activities focusing on art, observation, outdoor engineering, movement, and adventure. Resources can be used in formal and informal learning environments.
Objectives
* Learners will understand the astronomical phenomenon of solstice.
* Learners identify the differences in how solstice impacts their local, sub-arctic
This lesson was created by Rebecca Harris after being a part of the Arctic Glacial Lakes PolarTREC Expedition. She was inspired by how important suspended sediment, something so often overlooked by non scientists, was for developing paleoclimate models as well as ecosystems. Students will observe a watershed or a model of a watershed to make predictions about what might
This lesson plan was created by after being a part of the Arctic Glacial Lakes PolarTREC Expedition. I was inspired by the massive amount of data collected over the course of the research project and the complexity of hydrology in glaciated and non-glaciated basins in the Brooks Range of Alaska. Students will work together to make hypotheses about patterns
Through investigation, you will determine which solution has the highest density.
Objective
To determine, through experimentation, which of a variety of solutions has the highest density.
Preparation
Background: The waters of the ocean are constantly moving in many different ways. The surface of the ocean rises and falls in rhythm. These movements, in the form of

Students will build a simple plankton net from a nylon stocking, then (optionally) use it to collect plankton in ponds, lakes, streams, bays, oceans, or even aquariums.

Since most plankton is smaller than we can see, they must be looked at using a microscope. They are usually strained from the water using fine mesh nets or sieves with tiny holes. Typical plankton nets have a round opening and look like a funnel that leads into a collection bucket at the end of the net. The nets are
One of the simplest biological samplers, zooplankton nets are made in a wide variety of styles and sizes. The two nets in the MARMAP Bongo vertical-haul net system explained here each have a mouth diameter of about 25 cm.
