Welcome to STEM camp!
Today we talked about Biology, the science of living things! We learned about how seeds move and how plants grow. We talked about the parts of a plant. We also talked about the importance of water to living things.
Here is our Zoom meeting link:
Today is Tuesday, August 18.
The resources for today are posted below.
Did you know that trees can "talk" to each other?
Watch this video to find out how they do it and what they have to talk about!
Watch this video to see a bean plant sprout and grow!
Questions to ask:
What is happening to the bean?
Can you find the different parts of the plant? Stem, roots, leaves?
What does this plant need in order to grow?
Do all plants need the same things to grow?
What is Capillary Action?
Capillary action is how plants get water from way down in their roots all the way up to their leaves! Water molecules use Cohesion to stick to each other, Adhesion to stick to a solid surface, in this case, the inner walls of a plant's stems and roots, and Surface Tension which holds the water together at the top as it moves up the stem and roots holding the water molecules together so they don't fall down. The water molecules work together, pulling each other up, up, up because they stick together with the power of Cohesion.
You can try this simple experiment to see how capillary action works!
You will need:
3 clear cups, a roll of paper towels, food coloring.
Seed Scavenger Hunt
How many different kinds of seeds grow near your home? Every type of plant and tree has to have a way to reproduce, or grow more of itself! That's what seeds are for! Today we talked about how seeds can travel in 3 main ways: by water, by air, or by animal!
Take a walk slowly around your backyard (or a nearby park or a forest trail if you are near one).
Pay attention to plants on the ground and to those above, like trees.
Try to guess where the seeds from that plant are stored. Some are very visible, some are harder to see.
Look for berries, seedpods, flowers, nuts, and any other seed types you can find.
Collect samples carefully (be aware of poison ivy and remember to keep fingers and plants out of the mouth).
Look at the seeds and try to guess how they might travel. Do the seeds blow in the wind? Do they float over the water? Do animals eat them and poop out the seeds somewhere else? Do the seeds get stuck to their fur?
How many seeds did you find? Are there any seeds in the fruits or veggies in your kitchen?
See the picture for an example of the seeds Ms. Julia found walking around her yard!
What are natural resources? Why are they important to our survival?
Tuesday Experiment: Water Filter
Water can have dirt, bacteria, or other things in it that might make people sick if they drink it. That's why our water has to be filtered before we drink it! Today on Zoom we learned about how people are inventing portable filters for people to use to clean their water anywhere they go!
Today's activity is a homemade water filter. This filter will not clean our muddy water enough to be able to drink it, but it will show you how filters work by removing smaller and smaller pieces of contaminants as the water trickles down.
After you make your filter, look for other examples of filters in your home. Do they filter water, air, something else? How do you think they work?
Watch this video to see Ms. Julia explain how to set up your Sensory Jar for STEM week:
You will need:
Your sensory jar bag from the mystery box
A clear, empty plastic bottle with a cap (from home)
Please supervise your child carefully as many of these items are small and could be a choking hazard. You may want to glue the cap of the bottle on when you are done for extra security.
