Environment: Battling for Oxygen

In a math or life science class, "mini-me" models are created with cardstock to reflect a 1:10 scale of students' bodies. Learners measure each others' heights with meter sticks, and then reduce the size by 10. After this exercise, they...

When van Leeuwenhoek saw cells and single-celled organisms for the first time, he knew these small things were a big deal! Share his discoveries with young learners through a narrated video, model-building activity, and scale study....

She had a terribly busy day converting oxygen into carbon dioxide; now she just needs a moment to breathe. In the activity, scholars review the function of the respiratory system and discuss bioengineering's role in medicine/health and...

Here is a fascinating instructional activity about the life cycles of plants and animals, and other cycles found in nature. Learners explore the cycle of the moon, the tides, and other sequences of events in every day life. The big...

The most important chemical process on Earth is photosynthesis. Scholars explore the changes in the gases in our atmosphere as life on Earth developed. They create a model of photosynthesis and consider simple questions.

Young scientists construct an understanding of molecular compounds in this hands-on science instructional activity. Using LEGO® to model the atoms of different elements, students build molecules based on the chemical formulas...

Using gumdrops and toothpicks, students conduct a large-group, interactive ozone depletion model. Students explore the dynamic and competing upper atmospheric roles of the protective ozone layer, the sun's UV radiation and harmful...

Students make several models of the solar system to learn the positions of the planets in the solar system as well as relative distances and sizes. Creation of these models will help them identify the planets by size, shape, color,...

Students Use data sets from MY NASA DATA to produce graphs comparing monthly and yearly ozone averages of several U.S. cities. They analyze and evaluate the data and predict trends based on the data. In addition, they discuss and...

Pupils develop the concepts of flood stage, levees, floodplain, and the dynamics of river flooding. They construct river models and test various flow rates and volumes. This lesson has an excellent experiment for students to do.
