Easy Science Experiments Scientific Method

Easy Science Experiments Scientific Method – Teaching students about the processes scientists use is a key step in building a scientific foundation at the beginning of the year. In this post I will share a fun and simple science experiment for students to explore floating while learning the steps of the scientific method.

Milk and cookies are all children’s favorite foods. Why not use it to teach science? We thought milk and cookies were the perfect ingredients for our first science experiment, and of course we could eat leftovers too!

. This experiment allows students to observe and conduct experiments while investigating why some things sink and others float.

I want to start with a small lesson to introduce you to the concept of buoyancy and explain some more scientific terminology. Terms like molecule, density and buoyancy. I also ask “Why do you think some float and some sink?” “How can something as heavy as a cargo ship float on the sea without sinking?”.

I posed the question “Do cookies float?” And “will they sink or float in the milk?”. After going through the steps of the scientific method, I took note of the questions and guided my students to practical steps they could take to find out.

The students were divided into groups of 4 and each received 4 different cookies and 4 glasses of milk. I used mini cookies I found at Walmart and the dollar store.

Before starting the science experiment, the students observed the characteristics of each cookie and recorded them on a piece of paper. Then, they predicted whether the cookie would sink or float.

The Scientific Method: Steps, Uses, And Key Terms

When the students performed experiments, the results were not always what they expected. Some of the cookies sank right away, while others took a while. The students observed which cookies absorbed milk quickly and which did not.

Students draw their results and discuss why they think each cookie sank or floated. Here are some things students should consider: the weight of the cookies, are there visible air pockets and “Do you have 1 or 2 cookies with filling in the middle? Do they float because of the oils and fats they contain?”

This simple milk and cookie float experiment is super fun and a great activity to teach kids the scientific method.

The PowerPoint lecture and student handouts shown in this post are available in the complete science unit, Scientists and the Scientific Method.

Light, Sound, And Waves Science Fair Projects, Using The Scientific Method (physics Science Projects Using The Scientific Method)

This unit contains 10 science lessons, educational strengths, and science labs that introduce students to scientists, types of science, science tools and safety, and the scientific method. Three science experiments, student journal activities, posters, and anchor charts provide everything you need to start the year by laying the groundwork for future science lessons.

Breathing Leaf Photosynthesis Experiments for Kids Solids, Liquids, and Gases: Pop Science Experiments Rocks Architecture and Surface Writing

I’m Linda Camp, an elementary school teacher for 20 years with a passion for creating educational materials that excite students and make learning fun! Everyone wants to make slime these days. Because it’s a cool activity you can try! Did you know that making slime is also a cool science? To help your kids get more out of their slime-making experience, turn to science experiments and apply a little scientific method. Read on to find out how to set up slime science experiments and make cool science fair projects for 4th, 5th, and 6th graders.

Simple Summer Science: Explore The Scientific Method With Lollipops!

Homemade slime is a real snack for kids and a very popular activity right now that makes a great science fair project. We’ve tested our slime recipes over and over to give you the best activity possible!

We also have a very cool bubbly slime recipe. Watch the video and get the slime recipe here. Two chemistry demonstrations in one!

Chemistry deals with the states of matter including liquids, solids and gases. It deals with how different substances are put together and how they are put together, including atoms and molecules. Chemistry is the way substances behave or form new substances under different conditions. Like slime!

Sludge is an endothermic reaction, not an exothermic reaction. Endothermic reactions absorb energy (heat) instead of releasing energy (heat). Have you ever noticed how cold slime is?

Kids’ Science Projects

Mucin activators (borax, sodium borate and boric acid) reposition these molecules in a process called cross-linking!

This is a reaction between PVA glue and borate ions in the slime activator. Instead of flowing freely, the molecules become entangled to form a sticky substance. Think freshly cooked spaghetti versus leftover cooked spaghetti!

We always like to include a little homemade slime science in here! Slime is a great chemistry experiment and kids will love it too! Mixtures, materials, polymers, cross-links, states of matter, elasticity and viscosity are just some of the science concepts you can explore with homemade slime!

What is slime science? Borate ions from a slime activator (sodium borate, borax powder, or boric acid) are mixed with polyvinyl acetate (PVA) glue to create this cool, stretchy stuff. This is called cross-linking!

The adhesives are polymeric and consist of long, repeating, identical strands or molecules. These molecules flow over each other, and keep the glue in a liquid state. Until…

When borate ions are added to the mix, these long strands begin to bind together. They begin to tangle and mix until the substance is not like the liquid you started with and is thicker and more rubbery like slime! Mucus is a polymer.

Imagine the difference between wet spaghetti and leftover spaghetti the next day. When the slime forms, the tangled molecular strands look a lot like a clump of spaghetti!

We call them non-Newtonian fluids. Because there is a bit of both! Different amounts of foam beads are used to increase or decrease the viscosity of the slime. Can I change the density?

Science Fair Project Evaluation Checklist

You can use slime making to explore the states and interactions of matter. Find out more below…

You’ll want to apply the scientific method to transform your slime-making activity from a science demonstration to a slime science experiment. You can read more about using the scientific method with children here.

Remember, the secret to conducting a good science experiment is to have only one variable. For example, water can be a urinal. Water was removed from the recipe to ensure the slime needed water as an ingredient. The rest of the recipe remains the same!

We’ve compiled a list of slime science experiment ideas. If you haven’t tried slime recipes yet, we recommend learning how to make slime first!

Simplifying The Scientific Process

This was a really fun experiment we tried and the results were pretty cool! We tested and compared three different slime recipes, but you can do it with one type of slime and see what happens. Hint… liquid starch slime without water is no fun! If you want to choose just one recipe, try this Borax Slime or Salty Slime recipe instead.

This is a great opportunity to test Elmer’s Washable Classic School Glue along with Dollar Store/Staples brand glue or Crayola glue!

The key to this slime science project is determining how different batches of slime made with each brand of glue compare. Of course, keep the recipe and method for making slime the same each time. Think about what makes a good slime. Determine how elasticity and viscosity or flow measure the properties of each slime. Your observations about the “feel” of each slime are also valid data.

We tried the science experiment of this slime using the classic liquid starch slime recipe. That’s how we got to FLUBBER! Decide how you want to change the amount of glue. for example; You can make one batch with the usual amount of glue, twice as much glue, and half as much glue.

Scientific Method Worksheet

Similarly, if you want to change the amount of glue, change the amount of baking soda in a salty slime, or change a fluffy slime recipe, check what happens to the slime, put it without baking soda and compare. Baking soda is usually used to enhance this slime recipe.

What is the powder to water ratio for making borax free fiber slime? Test out your preferred consistency for gooey slime with our safe stringy slime recipe. We went through several groups to see which one worked best. Decide ahead of time how to measure the slime consistency for each batch.

How many styrofoam beads are best for homemade floors? This is how we test our flows and record the results along the way. Or you can be different
