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.
Some activities may be challenging for little hands, and your child might need help with the experiments in this week's mystery box. Look for green text on the posts below for some ideas on how to differentiate the activity if it is too challenging for your child, or ideas for extensions or questions to ask. Enjoy!
Here is our Zoom meeting link:
Today is Tuesday, August 18.
The resources for today are posted below.
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 n order 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!
You can try this simple experiment to demonstrate how water can move through a plant and provide water and nutrients to all its parts. Let your child help drop in the food coloring or twist the paper towels. While you wait for the water to travel up the paper towel, you can go on a Seed Scavenger hunt! (Directions below the video).
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!
Water is a very important part of life here on earth for all living things! Watch this video to hear a song that will teach you all about the water cycle.
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.
You may want to pour the various materials (charcoal, gravel, sand, rocks) into small cups for your child to pour into the filter, rather than having them pour from the bags. Before they pour in the dirty water, look at it together, and then compare it to the water that comes out of the filter. What changed? Look at any other filters you might have in your home, like a Brita filter or an air conditioner filter, and talk about how they clean water and air to make it safe.
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.
