What geometric patterns can we identify on a leaf?
- September 9
A mathematical pattern is any sort of repeated property - something occurs frequently in nature! Taking a look at magnolias in particular, we identify branching patterns in leaf veins, and their degree of sub-level repetition. This allows us to understand various geometric concepts. This material is based upon work supported by the National Science Foundation under Grant DRL 2115393.

How can we estimate the amount of produce in a garden?
- September 9
In order grow plants efficiently, making certain estimations is valuable - how well plants will grow, how much produce each plant will give use, or, even more fundamentally, how many plants we can fit in a given plot of land. Taking information we know about marigolds as an example, we showcase ways to determine these sorts of important predictions. This material is based upon work supported by the National Science Foundation under Grant DRL 2115393. Any opinions, findings, and conclusions or re... CONTINUE READING
Recipe Ratios: Which recipe uses more chiles?
- September 9
When using recipes, determining how much of each ingredient is needed is an important task - particularly if you're making an amount different than what the recipe directly instructs! By looking at two different recipes for salsa, and using ratios and unit conversions to make them more easily comparable, we can begin to determine how much of these wonderful garden ingredients we'd need to use for each dish. This material is based upon work supported by the National Science Foundation under Grant... CONTINUE READING
What determines where leaves are positioned on branches?
- September 9
Leaves are what plants use to gather sunlight, necessary for plants to grow and thrive. This means that it is to a plant's advantage if their leaves' position is such that all leaves receive the most possible sunlight - minimizing overlaps and shadow wherever possible! Different plants use different strategies and arrangements to make this happen, though there are some common trends across many different species. By using a protractor to measure the angles between leaves, we can tease out some o... CONTINUE READING
Is it possible to measure an animal’s behavior?
- September 9
Animals have a wide varieties of behaviors, many of which can be difficult to analyze. To make animal behavior research easier, scientists use ethograms - tables of possible behaviors that they can check off as the observation goes on. The ethogram used by zoo employees to study their elephants is discussed, and ways of making use of and presenting that data investigated. This material is based upon work supported by the National Science Foundation under Grant DRL 2115393. Any opinions, findings... CONTINUE READING
