Bonus Module: Lenses
This week’s Distance Learning theme is optics, light, and the electromagnetic spectrum.
On Wednesday, we looked at how refraction impacts the way we see an object in water. This module builds on that activity, by using a bowl full of water and a few household props to further explore the properties of lenses.
Stick to just the hands-on activity for younger learners, or bring in the written blog content for middle/high school physics-lovers!
At-Home STEM Activities: How Many Seeds?
In honor of National Wildflower Week, this week’s Distance Learning offerings are focusing on the plant world.
When fruits and other seed plants reproduce (make more of themselves), a tiny new plant embryo forms inside their seeds. The seed protects the embryo and stores food for it. Seeds are released by the parent plant and dispersed (sent to new places) by wind, water, or animal activity. If the seed lands where the conditions are right, the embryo germinates and grows into a new plant.
In this all-ages activity, we’ll practice our estimating, counting, basic math, and motor skills using the seeds from fresh cherry tomatoes! This activity is modified from a lesson developed by National Agriculture in the Classroom.
