We are so excited to host our Home School Science Fair again this year! I know the home schoolers are excited and already thinking about which experiments they would like to do. Below are the guidelines for the Science Fair. If you have any questions, please do not hesitate to ask your home school teacher, oremail Mrs. Patti at firstname.lastname@example.org.
Science Fair 2017 Rules and Guidelines
The Science Fair will take place during our regular class time on May 22nd. The students have two weeks to complete their experiments, as well create their presentation boards.
Students will setup and present during the first half of class. Parents are invited to attend from 2:15-3 pm.
We sent home a safety pledge with the students this week showing them ways to stay safe when performing their experiments. Remember: Safety First!
We want to encourage independent work with the students. Parents should be there for guidance and assistance, but make sure the students are performing as much as the experiments themselves as possible.
If you are researching a topic idea, make sure it is age-appropriate. For instance, a good Google search would be something like “Science Fair Projects for 3rd graders”.
If you have a tablet, you may show a video of the experiment in addition to the tri-fold board. However, the student will be responsible for bringing, setting up and keeping track of the equipment themselves. Our computers will not be available to the students.
Judging will be based on a variety of things including:
Did you follow the scientific method? Is each section presented on the tri-fold board?
Thoroughness of investigation and research
Clarity of presentation
Report of Findings
Creativity of ideas!
Awards will be given for 1st, 2nd, and 3rd place in each age group. Awards will be presented at the end of class.
The display board should be a tri-fold board. The students will be asked to include the following information:
Title – really big for everyone to see!
The Materials Used
The Results – charts or graphs
Your Conclusion – was your hypothesis right or wrong?
Have fun with the boards! Include pictures of you performing the experiments, or pictures of the end results.
**Please Note: We will not be performing the experiments in class, only the findings. You may bring props or end result, if it is not messy or space consuming. Please do not bring any live specimens, food or chemicals to class.
We look forward to seeing everyone’s presentations! Happy Experimenting!
If you plant a flower, you will provide food for pollinators like butterflies, bees, beetles, and even some birds. If you have insects, you will attract animals that eat them like frogs, toads, and lizards. If you have frogs and lizards, you will provide food for bigger animals like opossums, snakes, and larger birds.
Insects, reptiles, amphibians, birds, AND mammals? Look how many organisms you helped! All because you planted a flower.
My point? GO PLANT FLOWERS! 🙂 Start with the seed balls we sent home today! Our seed balls were made with potting soil, clay, and water. We added a wildflower seed mix in the middle of each ball. All you have to do is plant it somewhere in a pot or a garden, then water it, and wait for the beautiful blooms to arrive!
In addition to making seed balls to take home, we spent time in our meadow sweep netting for insects! Check out the pictures below. We did manage to get pictures of a few of the insects before we released them back to their habitats. Would you like to try and identify them? Check out Bug Guide or iNaturalist for references.
iNaturalist.org is an online community for people who love nature – like us! It is a place where you can record and share your wildlife observations, identify species of flora and fauna, talk with other naturalists, and learn about nature!
In celebration of National Citizen Science Day (April 15th) and Earth Day (April 22nd), iNaturalist is hosting a City Nature Challenge! Cities from across the nation are competing in a four day competition to see who has the most observations, species identified, and people participating. Houston, Austin, and Dallas/Fort Worth are the 3 cities competing in Texas. And of course, The Houston Arboretum & Nature Center was excited to join in the fun!
We grabbed our iPads and hit the trails with the Home Schoolers in search of as much wildlife as we could find! The pictures are being uploaded to iNaturalist.org today to be added into the final count for Houston!
The deadline for pictures is tonight, so go outside and take some shots of nature!
Toad adobes are a great project for your student to make! It is a fun and easy way to provide a habitat for a toad in your yard. Toads are beneficial creatures because they are a natural pest control for your garden. An adult toad can consume an average of 10,000 insects in one summer! That’s a lot of bugs and slugs!
Like most animals, toads prefer a certain habitat. You want to place your toad home in a shady spot where the soil is the dampest. You can put it under a bush, near a downspout, or under an air conditioner drip. You can place the adobe on a few rocks so the toad can hop inside. You can also lay it on it’s side and bury it a little in the dirt. (See pictures below).
Remember organisms also need water to survive. You can place a small, shallow saucer with water near the abode. Here are some of the awesome toad abodes decorated by our Home School kids this week!
Just a reminder! Only a few days left to register for April Home School!
In April, we will be learning about Urban Wildlife! We will see which animals have adapted to city life. The dates are April 10th, 17th, and 24th. We still have a few spots open if you haven’t already registered!
May will be Science Fair month! Students will learn about the scientific method while performing experiments. Then, they will create a science fair project at home to showcase on the last day of class. Class dates are May 8th, 15th, and 22nd.
We still have a few spots open for both months! Don’t forget to sign up!
Biomimicry has played a big role in the designs of transportation. Everything from boats and submarines to airplanes and helicopters have been based on the shape of various fish and birds. One of my favorite examples of transportation biomimicry is based on the sleek beak of the kingfisher.
In the late 1990’s, Japanese engineers designed their famous bullet train which allowed people to travel from city to city with speed reaching close to 200 mph! There was one big problem though. Whenever the train would exit the train tunnels it would create a sonic boom (a loud sound) that could be heard up to 400 meters away, waking up nearby residents and disturbing local wildlife. The sound registered well above normal environmental standards. People on the train had also noticed a change in atmospheric pressure when entering and exiting the tunnels. After studying the design of the the train, the engineers realized the shape of the train’s nose was the problem. It was round like bullet.
So we ask:
How does nature flow without turbulence?
How does it streamline to move efficiently?
Avid bird watcher and engineer Eifi Nakatsu looked to nature for a solution. Nakatsu noticed the kingfisher had a unique beak that allowed him to dive effortlessly into water with minimal splashing. The kingfisher’s spear-shaped beak and head pierces the surface of the water and creates an opening for the bird’s body to glide in smoothly.
Nakatsu redesigned the bullet train’s nose and front end to resemble the kingfisher’s wedge-shaped beak. The train can now travel smoothly through the tunnels with lower resistance and a lot less noise. And, thanks to the streamlining of the train, it uses 15% less energy and runs 10% faster.
In class, the students took on the role of engineers looking to make the best gliders. First, we learned about different animals who glide through air and water like flying squirrels, birds, and sea turtles. Next, students created one or two designs they thought would work. After they assembled their gliders, it was time to test and tune! We measured to see how far the gliders would go, if they flew straight, and checked to see what kind of landing it had. After that, they took them back inside for modifications and tweaks, and tested them again! There were some pretty awesome designs being made!
Here is your take-home challenge:
Water transportation! Research different ocean animals to learn their body shapes and any cool adaptations they have. Collect a bunch of materials from around your home (cardboard, foil, water bottles, tape, glue, scissors, Popsicle sticks, straws, etc) and have your student create a vessel for the water. It could be a sailboat, a large ship, or even a submarine! After their design is complete, test it out in a bathtub to see how well it moves in the water. Remember, engineers will try several designs to see what will work the best. Happy creating!
