As always, ns am excited to be earlier for another Saturday Science. We love experiments for kids! scientific research is such a staple in our house and also guides the rest of our lessons for the week. This week, I assumed it would be fun to share part old science fun us had prior to we ever before started homeschooling. This experiment is one us did as soon as Legoman was in 2nd grade because that his scientific research fair project.

Since this science experiment to be for scientific research fair, we necessary to follow the clinical method. If you are a continual here, you know exactly how much we love science and how we try to teach the correct procedures and techniques associated in scientific research explorations. This science experiment would be an excellent for any age, v some modifications and adult assist for the younger ages.

Question/ Hypothesis

Question: exactly how do assorted liquids tap water, flow water, salt water, carbonated water, and also soda result plant growth?

Hypothesis: Legoman predicted the the plant the was given the flow water would prosper the most.

Materials and Procedure

*

What we needed:

6 tree (all the exact same variety, about the exact same size)(We chose to use established plants to view the results of the liquids ~ above the tree growth)

6 different LiquidsWe used tap water, river water, salt water, carbonated water, and also soda but you could use any type of liquids your kid wants come investigate

PlantersRulerMeasuring Cup (to for sure you room using the same quantities of liquid with each plant)Journal and also pencil (for record data)

*
Procedure

Step One

We planted every plant in individual pots and used our handy label device to label each pot with the liquid we would certainly be providing it over the next two weeks. We additionally labeled each fluid container so the they would enhance the plants.

Something important about a science experiment is come teach children around constants (unchanging elements) and the variables (what you space manipulating).

For this project, our contants are the form of tree used, the container, and also the quantity of liquid for every plant.

Step Two

We measure up the exact same amount that liquid and “watered” each plant. Us notated the amount we offered (this will certainly vary relying on the dimension of her pot) We used 1/4 cup at the beginning. You will see in observations, that we later had to readjust this.

*

It is vital to note: We also measured each plant at the start of the task to obtain the beginning size because that each plant. We want to know just how much the plants prospered over time and having a baseline measure was an extremely important.

Step Three

Each day us measured each plant, “watered” it v the ideal liquids, and accumulated the data in our science notebooks. We repeated this for 2 weeks.

Observations/Data

*

Every job Legoman would grab his tray that plants, his ruler and also his liquids. He was excited to wake up up each day and also “get come work”. It was immediately obvious that the plant with the salt water was starting to wilt. Because that day one, many of the plants had actually not grown any, however the salt tree had began to shrivel.

If we were reporting this as a scientific research fair (and if girlfriend repeat this) we would report what taken place every day, with the measurements and the changes. However, I have to leave something because that you to discover out! Don’t you want to watch what happens?

*

One important observation us made was that the pots we used did not enable for the fluid to drain. This intended we essential to change the quantities and frequency we were offering out tree “water”. 

*

Results

We couldn’t think what occurred to the plants! Seriously, girlfriend will want to shot this one and also this is the perfect season! I want to have a printable obtainable for you but couldn’t uncover it. I’d love to understand if you room interested or have actually a require for a printable science journal and science task packet.

Legoman really had fun placing all his data right into the computer and making graphs because that his science board.

ARE YOU all set FOR much more SCIENCE FUN?
