Kinetic Energy

The concepts of potential and kinetic energy are two well studied concepts in physics. Children, often learn about them in elementary school grades. However, transforming these abstract concepts into concrete ideas can be challenging. So, I thought I would take an engineering activity that children love to do and combine it with science. I amContinue Reading

Parachutes on the Moon?

A few days ago, I posted an activity about moon craters. Many of you reached out to me and told me your children loved the activity. So, here is a similar activity: parachutes. Parachutes cannot be used in the moon because there’s no atmosphere. But, they make for a wonderful invention here on Earth. ThisContinue Reading

Swinging Blocks

A traditional experiment physicists study is pendulums. It is a cool experiment for children to semi-replicate at home. This experiment promotes connections to every day life-playground time. So, our question for this activity is: Is it faster to swing by myself or with my friend?  Bring the pendulum to a pre-determined height. Then, gently releaseContinue Reading

Observing Clouds

My first grade students have been fascinated by clouds. Logically, I wanted to unlock those wonderings with them. They wanted to know cloud names, how are clouds formed, why do they look so different, and much more. So I began to plan a chillaxscience lesson.

Obstructing or Hiding Science? A book that puts forward complexity

I love a good picture book that brings forward a complex topic! The author John Light and illustrator Lisa Evans did an amazing job depicting science as a taboo concept in their book The Flower (2006).

Homeschooling When a Rare Disease Attacks

When my youngest daughter was four years old, dermatomyositis, a rare autoimmune disease revealed itself. It was sudden, and caught us by surprise. The disease’s offset was fast and furious-within weeks, my baby couldn’t walk.

Advanced Evolution Work

My oldest child is very interested in the concept of evolution. Specifically, how animals (humans included) have changed over time to adapt to climatic changes. So far, she has used the traditional Montessori chart and has dived deep (through books) in the world of cheetahs and elephants. Because the Montessori key chart was not enough,Continue Reading

Teaching About the Layers of the Atmosphere

I don’t know about you, but summer season allures me to spend more time outside. With that, naturally, wonderings about the universe and my surroundings follow. The Montessori teacher in me (which drives my parenting style,) articulates those wonderings aloud in hopes that my children will also feel inspired to learn more about their surroundings.Continue Reading

How does Montessori Science Meet the Next Generation Science Standards (NGSS) ?

Becoming a Montessori teacher was a transformative experience for me. It gave me new knowledge on how to isolate science content that leads to easier understanding and retention. Montessori teaching also made evident the benefits of chillaxed teaching. Montessori teaching posed some problems because it presented science in a somewhat static and isolated way. ThisContinue Reading

What to Teach in Second Grade

Next Generation Science Standards (NGSS) NGSS has positively shifted the way we think about science teaching. Our science standards are now more comprehensive, coherent, and integrated across science disciplines. However, these changes present challenges in terms of time constraints. Oh wait, which teacher or homeschooler doesn’t have time constraints? If you are not familiar withContinue Reading

Storytelling in Science

Have you used storytelling in science? It is an underused technique! We often think of storytelling as an instructional technique in language arts and sadly not one for science. But, it gets children hooked into a topic and can provide a historical context in science. Atoms are invisible and an abstract concept to children. SoContinue Reading

Chemistry Lesson

My fifth grade students were ready to dig deeper in their study of rocks and minerals. So, we started following the “traditional” route of doing simple tests to identify the minerals present in the rocks they found in the playground. However, as we were doing these tests, I realized that I could take an alternativeContinue Reading

Science and Graphic Organizers

Graphic organizers have been in the world of education for a long time. If you google for example, the keyword ‘graphic organizer’ about 174,000,000 entries pop-up. Wow, what an overload! However, if you are a little more specific and use the keywords ‘science graphic organizer’ the number is reduced to approximately 38,900,000 results. Goodness, stillContinue Reading

Engineering in the Montessori Classroom

The engineering design process is an important element to include in the classroom, whether a Montessori environment or a traditional classroom. When guiding children to be part of the process we should consider the following elements as important: there’s a problem and there is access to attempt to solve the problem. In other words, childrenContinue Reading

Introduction to Microscopes

My children are intrigued by how things look under a microscope. So, I obviously wanted to turn such interest into a more in-depth learning experience. First, I took a picture of our microscope and labeled all the parts.

If you have a similar microscope and would like to use our picture, you can download it here for free Labeled Microscope. I didn’t spend a lot of time on the parts of the microscope as the objective of the lesson was simply to name the parts by its proper name. If you don’t have a microscope, Amazon has some excellent and affordable options.

We then jumped right into using the microscope within the context of learning how the internal parts of a plant help them survive, reproduce, behave, and grow. I used the commercial and economical set of slides by AmScope. Despite their low price they are very good quality. Great deal for the price! You can get them through Amazon or any learning store.

I wanted to guide their work hence, I used sugar and salt to get them thinking about how to describe substances in ways that are rich and useful. I prepared a microscope slide (labeled A) with sugar and another one (labeled B) with salt. We looked at these together and created a word bank of appropriate descriptive words by category. This is what they came up with some prompting.

Criteria Descriptors
Color White, blue, black, brown, gray
Geometric shape Prism, circular, asymmetrical, spherical, round, rectangular
Clarity Transparent, translucent, opaque, reflective
Pattern Repetitive, not visible

Although I usually encourage my children to write in their  journals I just wanted to have fun in the lesson, so they didn’t record the word bank. You may want to extend the lesson and encourage your children to record these observations in their science journal. It will be handy in future lessons, that’s for sure!

Finally, on a different day, I gave my girls the AmScope slides: fern root, fern stem, and fern leaf.  For each slide, the task was to observe, draw, and describe. We had a lot of fun and the girls can confidently and independently use the microscope any time!

The Story of the Earth

Introduction to the Geological Evolution of Planet Earth Over the years, I have noticed that children go deeper in science when it is interwoven with history and math.
