Dating a Volcanic Eruption

Young scientists show how carbon dioxide in the air affects plant growth. This math and science activity provides a good platform for learners to combine scientific knowledge with mathematical representation of data. A simple, yet...

Could the seasons be changing? Using National Park data, learners recognize patterns in the growth of seasonal plants. They look specifically at the first bloom date of cherry blossoms in Washington DC and compare them to temperature...

Did you know there are 20 volcanoes erupting at any given time? Pupils look at various igneous rocks, read local geologic maps, and determine if their area has a history of volcanic activity. A reading passage and analysis questions...

There can be a steep learning curve when teaching about exponential growth, but the instructional activity helps kids make sense out of the concept. When talking about exponential growth of viruses, learners may not be very interested,...

Whether you have your class plant seeds or begin when sprouts are visible, math skills are used here to predict and track growth over time. Straw bar graphs show plant height on a given day while the graph as a whole shows changes over...

If any of the limiting factors in an environment change, both animal and plant populations also change. The video explains two different models of growth and the impact of limiting factors. It highlights the carrying capacity of an...

Learners discover the various ways in which tree rings can give information. After a brief disucssion of concentric tree rings, they use cross section cut outs of tree rings to identify the time and type of various naturally occuring...

Fifth graders use modern technologies which allow them to gain a new, dynamic, and intersting understanding of themselves, their community, and the world. They focus on environmental education and the effect of the environment on plant...

Middle schoolers examine the growth of marigolds in a greenhouse environment. They chart data in spreadsheets showing plant growth over time and under a number of conditions. They record measures of plant height and greenhouse temperature.

Students construct a defined plot on school grounds and observed patterns in plant life. They count trees, shrubs, cacti and record on a data sheet. They compare data and generate a plant diversity overlook for their school.
