Sourgrass Natural Dye Video Tutorial

There’s more to sourgrass than its lip-puckering powers. Dig a little deeper with this natural dye video tutorial.

Sourgrass (Oxalis sp.) is a plant of extremes: children love its strong flavor, pollinators gorge on its abundant nectar, many adore its ability to overwhelm a field when in bloom, and many still detest the invasive qualities of some of its species. Oxalis pes-caprae, native to South Africa, has made itself comfortably at home in California, forming dense mats that outcompete native plant species for light and space.

Whether you love it or can’t stand it, sourgrass has an interesting hidden quality that is both useful and exciting: it dyes fabric a vibrant, neon, highlighter-yellow color. Watch our video tutorial to learn how to play with its pigment and explore more resources below:

What’s In a Naturalist’s Backpack?

Who is a naturalist?
It doesn’t take much to be a naturalist – anyone can be one! A naturalist is someone who enjoys spending time in nature, exploring aspects of the natural world, and making observations about the things that they see. Does that sound like you? If so, you are a naturalist! A naturalist is CURIOUS, EXCITED about learning and discovering, and RESPECTFUL towards all living and non-living beings in the world.

What do you need to be a naturalist?
Your most important tools are the senses you have available to you. Those senses may include: SIGHT, HEARING, TOUCH, SMELL, and TASTE. You can use these “tools” in so many ways to observe your surroundings and to discover patterns in nature!There are some other tools that naturalists bring with them to investigate nature more closely. Many of these tools can fit right inside a backpack, meaning that you can take them anywhere! 

Safety first!
Before we talk about WHAT you can bring on your adventure in nature, it’s important that we go over a few things to help keep you and the environment safe.

  • During Corona Virus Shelter-in-place orders: maintain a safe distance of 6 feet and explore the outdoors close to home rather than traveling far away.
  • Some essentials to pack: appropriate layers depending on the weather where you live, water to stay hydrated, a snack to fuel you through your day, and a first aid kit. If you’re going for an adventure further from your house, these things are very important!
  • Kids – make sure to take a trusted adult on your nature exploration. 
  • Avoid touching, picking, or eating plants that you are not familiar with. Even if you think you know what something is, it’s important to ask an adult and get an I.D. confirmation first. Never attempt to touch or approach a wild animal. 

Journal and Art Supplies 
A great place to start is with paper and pen or pencil. An important part of being a naturalist is taking notes and recording the things you see!

Why do you think it’s important to record observations in this way?

If you like to draw, you can take your favorite art supplies with you to make sketches of the things you see. There is no wrong way to nature journal! Ask questions in your journal, get creative, make graphs – it’s up to you! 

If you’re stuck on what to write about, you can try “I Notice, I Wonder, and It Reminds Me Of”. All you have to do is choose something you  see in nature and finish those sentences based off of the observations that you’re making with your senses! 

Some good resources to help you with nature journaling:

A page of notes relating to the definition and functions of a field guide

What’s That?
Have you ever been on a walk in nature, saw something AMAZING , and wondered, “What IS that?”. This is where field guides come in handy! A field guide is a book or handout that helps you identify things that you can find in the natural world. There are so many field guides out there in the world – whatever you are interested in, there is definitely a field guide for it! 

Field guides are great to use after you have spent time with your organism, making observations about what you notice about it. They can tell you the name of the organism as well as any other cool information about it! 

There are a lot of helpful books to get you started on your identification. Field guides can be foldable pamphlets, too – easy to carry around in a backpack! There are also so many field guides online that you can download to either print or view. You can even create your own field guide!

Look Closer!
Up close or far away – there are a lot of tools we can use to help us focus our eyes on the things we see in nature! Here are just a few.

Binoculars
Look! There’s a bird perched high up in that tree. One way to look at it a little more closely is by using a pair of binoculars. Binoculars are tools that have two lenses for your eyes that help magnify your vision.

How to Use Binoculars 

  • First, focus on the object you want to see more closely with just your eyes. Then, slowly raise the binoculars to your eyes. 
  • Adjust your binoculars. If it is blurry when you look through the lenses, you can adjust your binoculars to make them more clear. Your binoculars should come with a set of instructions on how to do this – often there is a knob at the top or around the lenses you can rotate.
  • Use binoculars only when standing still, not walking – you could trip and fall! Make sure to never look at the sun through your binoculars – this could cause permanent damage to your eyes.

Magnifying Glass or Hand Lens
These tools help us see details up close- like the scales on a butterfly wing, tiny hairs on a fuzzy plant, or tiny organisms swimming around in the water! Peer into a magnifying glass or hand lens and see what you can find.

 Good places to find these tools:

A bug net being held outdoors

Gettin’ Buggy!
Watch a spider spinning its web, follow a butterfly from flower to flower, or watch a worm wriggle in the dirt! There is so much to learn about these tiny creatures – they are not to be overlooked! 

There are ways we can safely look more closely at insects. An insect net is a tool that helps you safely capture insects so that you can make observations. You can carry some small jars with holes in the lid or sides to create a temporary home for the insect while you take a closer look. It is always better to just look with our eyes when we find insects, but if we are careful, we can use these tools to get a better understanding of our six-legged friends.

Remember! Never pick up or touch an insect you are not familiar with. Make sure to be gentle when using your net to observe living creatures. Always release insects in the same place you found them after you are done making observations! 

Now your bag is all packed and you’re ready to explore! 

  • Your senses, curiosity, and excitement will help you make observations and discoveries on your way.
  • Your field guides will help you go deeper and learn more about plants and animals that you find.
  • Your insect nets will encourage you to notice the similarities and differences between the insects you may see.
  • Your binoculars, hand lens, or magnifying glass will give you an up close view of nature.
  • Your journal will help you record your findings, take notes, draw pictures, and ask questions about the things you find along the way!

Who knows what wonderful surprises you’ll find out in nature?

Weather Observation Activity | 3rd grade

Careful observation and data collection are practices that all scientists and naturalists employ to aid in exploring and understanding the natural world. Weather provides a great way for students to practice both, as they watch from their window or take measurements outside. As students begin to detect patterns and notice differences in weather, questions emerge: how do clouds affect temperature? What about wind? Is what I’m seeing normal for this time of year? Diving into weather observations reveals a world of phenomena at play all around us every day.

This lesson is designed to run over the course of a week or more, requiring small time commitments of 5-10 minutes each day from individual students and then either group or self-reflection and analysis at the conclusion.

Skull Detectives Activity | 2-3 grade

beaver skull

There’s a mystery that we need to solve. What do these animals eat? Observe three different native animal skulls and learn about different types of teeth to solve this mystery! 

In this 30-40 minute activity, students will use a slideshow to guide them. Students will learn about the different types of teeth that animals have, and how teeth can be clues that help us figure out what an animal eats. Students will observe three different native animal skulls and make educated guesses about if they are a carnivore, herbivore, or omnivore. Based on their learning, they will draw one of the animals and label the different types of teeth. 

This activity was adapted from the Our Animal Neighbors Program for distance learning and is for 2nd and 3rd graders. It can be used with younger grades, but students may need assistance with reading.

Prompt: Engage Your Senses

There are so many great ways to use a nature journaling project to connect to your local habitat(s). One of my favorites is sequential observations — making notes and sketches about an organism you observe over time. Spring is a great time to do this because there are so many visible changes happening in our environments.

Your yard may look like a bunch of weeds but somewhere hidden amongst the chaos is an oasis you can indulge in for a little while.

The finished painting of the cacti

Find a sit spot in your yard where there is something that has caught your eye. Take a comfortable seat and before even putting pen to paper just sit and take everything in. Use all your senses to hear, see, smell, feel, and maybe even taste the elements, plants, and critters that surround you.

Do a quick free write to get your brain juices flowing and then sketch away and enjoy the comfort and beauty of your own home!

Community Connections

During these isolating times, it’s more important than ever to connect with nature and to connect with our community. Even from home, you can help nature and inspire stewardship of the natural world! Below are a few of our favorite stewardship and community science opportunities. In addition to environmental stewardship projects, we also encourage you to be a steward of your social community.
For all volunteer and stewardship programs, be sure to maintain safe practices as highlighted here.


Stewardship

The produce section of a large grocer

Volunteer Grocery Shopper
Help homebound seniors and others in need by shopping for their groceries. The individual will provide you with a list, and you leave the groceries at their door. Give essential assistance to members of your community who require extra help.

Resources: Sign up at the Volunteer Grocery Shopper form here. Background checks and some other paperwork required (takes about one week to process).


Connections Without Walls
Give social support to isolated elderly adults across the country with simple phone calls. This flexible program is offered for free during the COVID-19 outbreak as so many people (including you and me) need friendly socializing. It’s a good way to connect to our national community in times of need.

Resources: Sign up with the Family Eldercare program here.


Neighborhood Cleanups
One way you can be a steward of both your community and your planet is by doing a neighborhood or beach cleanup. Get started with this tutorial:

Notice: Access to beaches and parks may be limited due to ordinances regarding COVID-19. Please check your local guidelines for up-to-date guidelines.

Community Science

iNaturalist
One of the best ways to advance science is by utilizing the community to build a previously unheard of body of knowledge and researchers both locally and globally are using data found on iNaturalist. Simply photograph and record the location of what you find to build a database of your observations and contribute to studies of how ecosystems are changing with time.

With iNaturalist you can explore nature, take photographs, and help scientists. What’s not to love? Get started!

Sudden Oak Death Bioblitz
California’s iconic oak trees suffer from a devastating disease known as Sudden Oak Death (SOD). UC Berkeley’s community science program invites volunteers to track the spread of SOD by walking through forests, identifying trees that have SOD, and creating a real-time map of the trees and forests affected. 

This does require some training (watching a video and answering a questionnaire), as well as the use of both a website and app. The bioblitz can be done by all ages.

Ohlone Matching Game | 3-4 grade

Native people living along the Central California Coast practicing the Ohlone culture understood nature and responsibly stewarded resources for their survival. Do you know what it means to be a steward of nature? To be a steward is to take care of something. To be a steward of nature you first must understand nature and then you can learn how to care for it and preserve it for the future. In the past and today people have depended on natural resources to survive. Today we are going to learn about natural resources that were important to the Ohlone.

Matching Game
This 20- to 30-minute activity is for students to learn about natural resources that were important to the Ohlone culture and reflect on natural resources that we rely on today. Students will look at photos and read descriptions of natural resources and match the resource with the artifact they think came from it. Students will check their own answers by reading facts about the artifacts. This activity was adapted for distance learning from the Ohlone Classroom Kit and was created for 3rd/4th graders.

Science Illustration Prompt: Sequential Observations

Explore science illustration with artists featured in our annual exhibit, The Art of Nature, and get tips for how to make your own science illustrations at home. This post is from Megan Gnekow, recipient of the Museum’s 2019 Laura Hecox Naturalist Award.

I make scientific illustrations because I want to inspire folks to look closely at the world around them. I want to make complexities and relationships more clear, helping people understand that all organisms are connected to each other. — Megan Gnekow

Prompt: Sequential Observations

There are so many great ways to use a nature journaling project to connect to your local habitat(s). One of my favorites is sequential observations — making notes and sketches about an organism you observe over time. Spring is a great time to do this because there are so many visible changes happening in our environments.

Choose an organism that you can observe regularly over a period of time (the period of shelter-in-place is a good place to start!). Observe the organism you have chosen as frequently as you are able to and make notes and sketches about what you observe. Note date, time, location (macro-habitat and micro-habitat). Use as many of your senses as you can and record what you learn!

Recording your observations over time gives you insights into an organism and the environment in which it lives. Hopefully this plants a seed for further observations and exploration. Don’t worry about making beautiful drawings. Just sketch and/or note what you observe! 

If you can’t get outside or have other limitations to observing organisms, there are plenty of webcams available to inspire you — I would suggest a bird camera hosted by the Cornell Lab of Ornithology or the falcon cam at UC Berkeley.
